Cognitive-behavioural impairments after forebrain ischemia in rats: Relationship to disruptions in emotionality and neuroendocrine regulation
Creators: name: Milot, Marc R

Subjects: subject: Psychology, General.

description: Cognitive deficits observed in rodents subjected to forebrain ischemia (mimicking the cerebral ischemia observed following cardiac arrest) are generally interpreted as produced by neuronal degeneration to discrete regions of the brain, principally the hippocampus. Challenging this view, the presence of ischemia-induced neuronal damage is not always associated with manifestations of cognitive impairment, or conversely, impairments post-reperfusion can originate at times when neuronal damage has yet to occur. The current thesis investigated whether the impairing effects of ischemia on cognitive functioning might in part be attributable to endogenous alterations of emotional systems regulating anxiety, stress, and/or arousal, thus not exclusively to discrete neuronal damage. The behavioural findings of Experiment 1, 2 and 3 suggested that hyperactivity in response to novel testing contexts in ischemic animals (as measured in the open field) is modulated by changes in emotional reactivity, and demonstrated time-dependent alterations of anxiety and behavioural activation at discrete reperfusion delays following a 10 minute forebrain ischemia. In Experiment 4, we demonstrated that cerebral ischemia is a significant stressor having lasting impact on HPA axis reactivity, effects associated to spatial memory impairments at delayed post-reperfusion intervals. Specifically, the testing-induced elevations in plasma corticosterone observed in ischemic rats (to a greater extent than sham-operated rats) was elicited after a return to pre-surgery resting levels, suggesting that increased neuroendocrine response was the result of behavioural testing and closely associated with cognitive deficits. Finally, Experiment 5 showed that excessive central noradrenergic reactivity in ischemic rats mediated some of the observed cognitive impairments or behavioural alterations. Overall, the thesis experiments suggest that cognitive-behavioural outcome after forebrain ischemia in rats is associated with impaired emotional regulation and/or arousal. These findings are not compatible with the common hippocampal-based interpretation of cognitive deficits after ischemia, and question the ecological validity (and generlizability) of functional outcome measurements of rats subjected to cerebral ischemia given that cognitive impairments in human survivors of ischemic episodes are not considered the result of arousal deficits.

description: Academic staff often find it difficult to introduce active learning principles into lectures, where the room design often prohibits movement and focuses attention on the teacher. This paper describes a new interactive quiz on plagiarism, and discusses how this resource was used in a lecture to trigger lively class discussion. The quiz (and how it was incorporated into the lecture format) will be demonstrated at the forum presentation.
Thriving in the academic domain: The role of career development on academic self-determined motivation

Publisher: name: Université d'Ottawa / University of Ottawa
Year: 2009
Subjects: subject: Psychology, General.

description: The central purpose of the present research project was to examine the role of career development on academic motivation among adolescents. Based on self-determination theory (SDT; Deci & Ryan, 1985a) and future-oriented frameworks, it was hypothesized that two career development indices, namely career decision-making need satisfaction (i.e., competence, autonomy, and relatedness) and career decision progress would be associated with enhanced academic self-determined motivation. Second, perceived usefulness of school activities was expected to mediate the relationship between career decision progress and academic self-determined motivation. Third, the two career development indices were anticipated to contribute to perceived usefulness and academic self-determined motivation over and above the effect of academic need satisfaction. Four studies, using various methodologies and multiple age groups were conducted to test these hypotheses. Study 1 (n = 60) and Study 2 (n = 207) examined the role of career decision-making need satisfaction (i.e., competence exclusively) and career decision progress in the prediction of academic self-determined motivation. Using a two-wave longitudinal design, Study 1 showed that the career development indices contributed to variance in academic self-determined motivation over and above gender and baseline academic self-determined motivation. Using a pre-experimental design, Study 2 (i.e., pre-post career development course) demonstrated that an increase in the career development indices was associated with an increase in perceived usefulness and in academic self-determined motivation. Moreover, perceived usefulness mediated the relationship between career decision progress and academic self-determined motivation. Study 3a (n = 637) and Study 3b (n = 243) included satisfaction of all three needs postulated by SDT. Using a cross-sectional design (Study 3a) and a two-wave prospective design (Study 3b), findings showed that academic need satisfaction was associated with academic self-determined motivation, and that perceived usefulness partially mediated this relationship. Furthermore, Study 3b found that career decision-making need satisfaction and career decision progress contributed to variance in perceived usefulness and academic self-determined motivation, even after statistically controlling for academic need satisfaction. Together, these studies suggest that need satisfaction in both life domains and career decision progress enhance academic self-determined motivation. Future research pertaining to the role of career development on motivation is discussed.

description: Interest in behavioural ecotoxicology is growing, partly due to technological and computational advances in recording behaviours but also because of improvements of detection capacity facilitating reporting effects at environmentally relevant concentrations. The peer-reviewed literature now contains studies investigating the effects of chemicals, including pesticides and pharmaceuticals, on migration, dispersal, aggression, sociability, reproduction, feeding and anti-predator behaviours in vertebrates and invertebrates. To understand how behavioural studies could be used in regulatory decision-making we: (1) assessed the legal obstacles to using behavioural endpoints in EU chemicals regulation; (2) analysed the known cases of use of behavioural endpoints in EU chemicals regulation; and (3) provided examples of behavioural endpoints of relevance for population level effects. We conclude that the only legal obstacle to the use of behavioural endpoints in EU chemicals regulation is whether an endpoint is considered to be relevant at the population level or not. We also conclude that ecotoxicity studies investigating behavioural endpoints are occasionally used in the EU chemicals regulation, and underscore that behavioural endpoints can be relevant at the population level. To improve the current use of behavioural studies in regulatory decision-making contribution from all relevant stakeholders is required. We have the following recommendations: (1) researchers should conduct robust, well-designed and transparent studies that emphasize the relevance of the study for regulation of chemicals; (2) editors and scientific journals should promote detailed, reliable and clearly reported studies; (3) regulatory agencies and the chemical industry need to embrace new behavioural endpoints of relevance at the population level. © The Royal Society of Chemistry 2020
Globalized e-curriculum making and/as cyberfeminist poetics
Creators: name: Arnold, Josie
Publisher: name: Swinburne
Year: 2024

description: Is the global inherently flawed by its Western patriarchal source? In what ways can cybercolonisation act against gender blindness? This paper looks at the ways in which cyberfeminist ideas of textuality and discourse might fruitfully be conceptualised and explored to open up the influence of feminist poetics upon e-curriculum-making and hence the student experience of online multi-media. Clearly, the ways in which we view cultural representation influence the spaces provided in the cyber. Thus, an important aspect of e-education is a consideration of the possibilities for cyber-colonisation as being disruptive to dominant cultural real-space 'norms'. This paper explores how the cyber enables and is enabled by laterality of discourse. It proposes that the experience of writing online curriculum multi-media materials is a contemporary challenge to educators. In doing so it both proposes and explicates 'subjective academic narrative' as a feminist research methodology. It is based upon my experiences and insights as a teacher, academic and widely-published writer in a number of genres, including interactive multi-media and curriculum.

description: Due the sheer size and complexity of genomes, it is essential to develop automated methods to analyze them. To compare genomes, one distance measure that has been proposed is to determine the minimum number of evolutionary changes needed to transform one genome into another. In recent years, great progress has been made in this area with efficient exact algorithms that can transform one genome to another applying a wide range of evolutionary operations. However, gene duplications, a common occurrence and arguably the most important evolutionary operation, have proven to be one of the most difficult evolutionary operations to integrate. We examine the most successful gene duplication algorithms: a family of algorithms that we call the rearrangement-duplication algorithms. Rather than compare two genomes, these algorithms attempt to efficiently remove the duplicates from a genome using the fewest number of duplications and other evolutionary operations. In this thesis we give a complete survey of all the genome halving algorithms, a highly successful group of rearrangement-duplication algorithms that efficiently and exactly handle whole genome doubling ( tetraploidization). We also introduce the genome aliquoting algorithms, a new variation on the genome halving problem, that attempts to handle unlimited scale whole genome duplications. As a new and challenging problem there are currently no efficient exact algorithms. However, early results include two approximation algorithms.

description: Prioritizing brownfields for redevelopment in real estate portfolios can contribute to more sustainable regeneration and land management. Owners of large real estate and brownfield portfolios are challenged to allocate their limited resources to the development of the most critical or promising sites, in terms of time and cost efficiency. Authorities worried about the negative impacts of brownfields - in particular in the case of potential contamination - on the environment and society also need to prioritize their resources to those brownfields that most urgently deserve attention and intervention. Yet, numerous factors have to be considered for prioritizing actions, in particular when adhering to sustainability principles. Several multiple-criteria decision analysis (MCDA) approaches and tools have been suggested in order to support these actors in managing their brownfield portfolios. Based on lessons learned from the literature on success factors, sustainability assessment and MCDA approaches, researchers from a recent EU project have developed the web-based Timbre Brownfield Prioritization Tool (TBPT). It facilitates assessment and prioritization of a portfolio of sites on the basis of the probability of successful and sustainable regeneration or according to individually specified objectives. This paper introduces the challenges of brownfield portfolio management in general and reports about the application of the TBPT in five cases: practical test-uses by two large institutional land owners from Germany, a local and a regional administrative body from the Czech Republic, and an expert from a national environmental authority from Romania. Based on literature requirements for sustainability assessment tools and on the end-users feedbacks from the practical tests, we discuss the TBPT's strengths and weaknesses in order to inform and give recommendations for future development of prioritization tools.© Elsevier 2016

Year: 1997
Subjects: subject: Biology, Molecular.

description: I have examined the fidelity of both the DNA-dependent DNA polymerase and the RNA-dependent DNA polymerase activities of five different forms of recombinant HIV-1 reverse transcriptase (RT). The DNA synthesis fidelity assay was based on the frequency with which mutations were introduced into the lacZ gene of Escherichia coli (E. coli). RNA and DNA of the lacZ reporter sequence were used as templates for DNA synthesis and the frequency of mutation was determined by the frequency of appearance of light blue or colorless colonies of E. coli on reporter plates. My results show that these enzymes are active and are error-prone during synthesis in vitro with DNA and RNA templates. Overall, fidelity of synthesis from an RNA template is lower than that from a DNA template. Sequence analysis of mutants generated with the two substrates reveal that base substitutions are random, whereas deletions and insertions are base specific. 'Hot spots' are observed with the mature form (p66/p51) of RT but not with the precursor forms of RT. In both DNA and RNA-dependent DNA synthesis, the mature form of the RT (p66/p51) has the highest error rate and the precursors have significantly lower error rates. In addition, the HIV-1 integrase domain appears to confer higher fidelity to the mature p66/p51 polymerase. I propose that the RT precursor plays a significant role in the replication of the virus and that the hypermutability observed with the virus is a result of multiple factors which include RT and selection for surviving mutants.

description: The purpose of this study was to compare the pattern of blood pressure (pressor) response to isometric handgrip contractions between older and younger males with and without blood occlusion. Ten older males (mean age 54.7 +/- 3.0 yrs) and ten younger males (mean age 26.6 +/- 1.9 yrs) normotensive at rest and dynamic exercise participated in this study. Following the determination of their maximum voluntary contraction (MVC), subjects performed handgrip contractions (dominant) at 20%, 40%, and 60% MVC (for 30 seconds), and at MVC (for 12 seconds), with and without blood occlusion. Systolic blood pressure (SBP), diastolic blood pressure (DBP), mean arterial pressure (MAP) and heart rate (HR) responses were recorded at every 5 seconds for the 20%, 40%, and 60% MVC, and at every 2 seconds during the MVC test using a Finapres BP monitor. Results indicated that without blood occlusion the mean absolute SBP, DBP, and MAP to isometric handgrip contractions were significantly higher in the older males than in the younger males for all contraction intensities although the mean absolute HR at all intensities was significantly lower in the older males. With blood occlusion, the mean absolute SBP was also significantly higher for all contraction intensities in the older males; mean absolute DBP was significantly higher in the older males only at MVC and mean absolute MAP was significantly higher in the older males except at 60% MVC. Mean absolute HR was again significantly lower in the older males during blood occlusion. However, there were no significant differences with and without blood occlusion between the two age groups in the slopes of SBP, DBP, MAP, and HR responses to the isometric contractions except for DBP at 60% MVC with blood occlusion, which was higher in the younger males. Within the younger age group, the mean absolute SBP was significantly greater with blood occlusion than without blood occlusion at 20% and 40% MVC, but similar at F 60% MVC and at MVC; mean absolute DBP and MAP were significantly higher with blood occlusion than without blood occlusion at 20%, 40%, and 60% MVC but not at MVC. Mean absolute HR was similar between blood occlusion and no blood occlusion for all contraction intensities. Within the older age group, there were no significant differences between with and without blood occlusion for mean absolute SBP, DBP, MAP, and HR responses to isometric handgrip contractions. It is concluded that although absolute pressor response to isometric handgrip contractions is higher in older males, the pattern of pressor response to isometric handgrip contractions is similar between the two age groups. Blood occlusion during isometric handgrip contractions did not influence the pressor response of older males. However, blood occlusion increased in the pressor response of younger males at lower percentages of MVC.

description: Introduction: Dyspareunia has been traditionally divided into superficial (introital) dyspareunia and deep dyspareunia (pain with deep penetration). While deep dyspareunia can co-exist with a variety of conditions, recent work in endometriosis has demonstrated that co-existence does not necessarily imply causation. Therefore, a re-consideration of the literature is required to clarify the pathophysiology of deep dyspareunia. Aims: To review the pathophysiology of deep dyspareunia, and to propose future research priorities. Methods: Narrative review after appraisal of published frameworks and literature search with the terms (dyspareunia AND endometriosis), (dyspareunia AND deep), (dyspareunia AND (pathophysiology OR etiology)). Main Outcome Variable: Deep dyspareunia (present/absent or along a pain severity scale). Results: Potential etiologies for deep dyspareunia include gynecological, urological, gastrointestinal, nervous system, psychological, and musculoskeletal system related. These etiologies can be classified according to anatomic mechanism (contact with a tender pouch of Douglas, uterus-cervix, bladder, or pelvic floor, with deep penetration). They can also be stratified into four categories (as previously proposed for endometriosis specifically), which can be utilized to personalize management: Type I (primarily gynecologic), Type II (non-gynecologic comorbid conditions), Type III (central sensitization and genito-pelvic pain penetration disorder), and Type IV (mixed). Sociocultural and genetic factors and sexual response may also be important for deep dyspareunia. Conclusion: We propose the following eight research priorities for deep dyspareunia: 1) development of deep dyspareunia measurement tools; 2) focus on the population who are avoiding intercourse due to deep dyspareunia; 3) clarification of the role of non-gynecologic comorbidities in the generation of deep dyspareunia; 4) addressing of ethnic and other sociocultural factors; 5) initiation of clinical trials with adequate power for deep dyspareunia outcomes; 6) inclusion of partner variables; 7) elucidation of pathways between psychological factors and deep dyspareunia; and 8) empirical validation of personalized approaches to deep dyspareunia.

Consequences of loss of the murine dsRNA-dependent protein kinase, PKR, by natural mutation or genetic ablation.
Creators: name: Abraham, Ninan.

description: The IFN-induced, dsRNA activated protein kinase PKR, is a member of the family of eIF-2 a protein kinases that has well defined roles in anti-viral, anti-proliferative and apoptosis responses. Using a strategy designed to identify phosphotyrosine protein kinases, we have identified PKR as a member of the family of dual specificity kinases since it phosphorylates residues on serine, threonine and autophosphorylates on tyrosine residues. Although this activity has not yet been identified in mammalian expression of PKR, the significance of this novel property raises the possibility of new signaling pathways impinged by PKR. This work examined the consequences of mutation of PKR, initially examining a mutation identified in a lymphocytic leukemia cell. The putative mPKR del polypeptide encoded by this mutation was cloned and tested in expression studies. Although mPKRdel was shown to be catalytically inactive and to bind dsRNA and endogenous PKR, it nonetheless did not demonstrate transdominant inhibition of PKR or alter cell growth when expressed. Instead, no evidence of expression of the mutant polypeptide could be found in the lymphocytic leukemia cell and it is believed the mutation is either silent or exerts an effect not evident in our assays. A more direct approach to the implications of loss of PKR function was taken using targeted disruption of PKR in the mouse by homologous recombination. Functional ablation of PKR was accomplished by targeting the catalytic domain, in contrast to others who had disrupted PKR at the amino-terminal end. The absence of elevated tumorigenesis, normal anti-vaccinia and influenza responses, intact apoptotic induction and unimpaired cytokine signaling was unexpected. Although possible that a subtle phenotype has been missed, the major finding of this work is that non-concordance in phenotype compared to the other PKR-null model suggests that loss of PKR can be compensated by previously unappreciated homologs. The unambiguous inactivation of PKR catalytic function has allowed us to determine that rescue of PKR ablation is occurring since phosphorylation of eIF-2 a is unaffected. Finally, PKR ablation appears to impair Epo signaling in erythroid CFU suggesting non-redundancy in these cells.

description: Accurate subtraction of the bright night sky emission lines in the near-infrared is crucial, given that the object being observed is often several magnitudes fainter than the sky background. Most integral field spectrographs (IFS) have a modest field of view (FoV), and it is often not possible to achieve good sky subtraction by nodding the object within the FoV, as is common practice for long slit spectrographs. In principle, it should be possible to use sky background information from one part of the FoV (typically the periphery) to subtract the sky from all other parts of the IFS FoV. However, this has never been achieved in practice. We show that the reason on-IFU sky subtraction does not work is that the spectrograph spectral response function (line spread function, or LSF) varies strongly with wavelength, position within the field of view, and telescope pointing (flexure). By micro-stepping the grating of the SINFONI IFS at the ESO-VLT, we have been able to hyper-sample the spectral PSF and reconstruct detailed LSF profiles for all wavelengths and all field points for SINFONI H band data. Using this information, we can conclusively demonstrate improvements in observing efficiency by over a factor of two. Our technique not only removes the need for separate sky exposures, but can also improve the noise of the sky background measurement itself, providing further potential gain over pairwise frame subtraction. We explain our algorithms, including non-parametric descriptions of the LSF, and present the results from applying our method to archival SINFONI data.

The Potential of Using Immobilized Xylanases to Enhance the Hydrolysis of Soluble, Biomass Derived Xylooligomers

description: Earlier work had indicated that enzyme-mediated hydrolysis of xylooligomer-rich water-soluble streams (derived from steam pre-treated wheat straw) resulted in the effective production of xylose which was subsequently used to produce bio-glycol. In the work reported here, both the thermostability and recyclability of xylanases were significantly improved by covalent immobilizing the enzymes onto alginate beads. The immobilized xylanases showed a lower hydrolytic potential (~55% xylooligomer conversion) compared to the commercial xylanase cocktail HTec3 (~90% xylooligomer conversion) when used at the same protein loading concentration. This was likely due to the less efficient immobilization of key higher molecular weight enzymes (>75 kDa), such as β-xylosidases. However, enzyme immobilization could be improved by lowering the glutaraldehyde loading used to activate the alginate beads, resulting in improved hydrolysis efficacy (~65% xylooligomer conversion). Enzyme immobilization improved enzyme thermostability (endoxylanase and β-xylosidase activities were improved by 80% and 40%, respectively, after 24 h hydrolysis) and this allowed the immobilized enzymes to be reused/recycled for multiple rounds of hydrolysis (up to five times) without any significant reduction in their hydrolytic potential.
Accurate indoor positioning methods for smart devices using improved pedestrian dead-reckoning and collaborative positioning techniques
Creators: name: Liew, Lin Shen
Publisher: name: Swinburne
Year: 2024

description: This thesis investigates and proposes methods that can accurately estimate the locations of smart-device users in indoors, by leveraging on only smart-devices and Wi-Fi access points. Today’s smart-devices contain various sensors which can be utilized to predict user’s motion, e.g. how far its user has walked and what direction is he/she moving towards. The estimation accuracy can be further enhanced by making use of the wireless signals emitted from surrounding Wi-Fi access points and smart-devices of other users. The research contributes to the development of indoor positioning system (IPS) which will make Location-Based Services possible in indoor environments whereby the Global Positioning System (GPS) is unavailable.

description: Carbon nanoparticles are newly discovered materials that possess interesting optical properties and can be used for sensing applications. This work reports the simple synthesis approaches for the production of homogenous spherical carbon nanoparticles using alginate as starting precursor. Optimum synthesis conditions have been obtained and the properties of the carbon nanoparticles have been characterised. The unique fluorescence has been leveraged for optical sensing of ferric ions, ascorbic acid and cardiac troponin T. This leads to the potential for real applications in environmental monitoring and as medical diagnostic tools.

description: The officers of Parliament now form a group which includes the Auditor General and seven other "ethical regulators"i. Because of its independence and the nature of its members' mandates, this group is thought to be key to restoring the public's faith in government. However, the officers do not clearly fall within one of the three branches of government and are not fully subject to democratic accountability mechanisms, raising questions about the legitimacy of their exercise of authority. This thesis explores alternative theories for supporting the legitimacy of officers of Parliament and draws lessons from that exercise for the future development of this virtues-based institution.

description: The International Breakfast Research Initiative (IBRI) set out to derive nutritional recommendations for a balanced breakfast using a standardized analysis of national nutrition surveys from Canada, Denmark, France, Spain, UK and the US. In all countries, the frequency of breakfast consumption by age was high and U-shaped with children and older adults having a higher frequency of breakfast consumption. Breakfast contributed 16% to 21% of daily energy intake. In all countries, breakfast was a carbohydrate- and nutrient-rich meal, providing more carbohydrates (including sugars), thiamin, riboflavin, folate, calcium, potassium, and magnesium, and less vitamin A, fats and sodium relative to its contribution to daily energy intakes. Breakfast consumers were stratified by tertiles of the Nutrient Rich Foods (NRF) index, used as a measure of diet quality. Breakfast intakes associated with the top tertile of NRF, along with the Codex Alimentarius international food standards and World Health Organization (WHO) diet guidelines, were used to derive the proposed nutrient recommendations. The goal was to preserve the nutrient density of existing breakfasts, while addressing concerns regarding added sugars, saturated fats, dietary fiber, and vitamin D. This initiative is unique in seeking to derive nutrient recommendations for a specific meal using the observed nutritional profile of such meal.

description: It's difficult to imagine anything other than a comfortable change of government at the next federal election. This judgement is not greatly influenced by the recent result in Western Australia, where a huge two-party-preferred swing to Labor delivered it almost 70 per cent of Legislative Assembly seats. Despite the inevitable scramble to draw federal meaning from state outcomes, and the routine overlaying of state results onto federal boundaries, the record shows that one does not portend the other, except on random occasions. The reason we should expect Labor to win the next election – gather around everyone, take notes – is the opinion poll figures. Stretching back almost to the last election, they have had the opposition consistently and comfortably ahead, recently by large amounts, and most often these days by about 6 per cent.

description: Background Peritoneal carcinomatosis occurs in different cancer subtypes and is associated with a dismal prognosis. Some doubts remain whether the whole abdomen can be treated by regional hyperthermia, therefore we analyzed feasibility conducting a pilot study. Methods A simulation of the abdominopelvic heat distribution in 11 patients with peritoneal carcinomatosis was done using the HyperPlan software and the SIGMA-60 and SIGMA-Eye applicators. Tissue-specific region-related electrical and thermal parameters were used to solve the Maxwell’s equations and the bioheat-transfer equation. Three-dimensional specific absorption rate (SAR) distributions and, additionally, estimated region-related perfusion rates were used to solve the bioheat-transfer equation. The predicted SAR and temperature distributions were compared with minimally invasive measurements in pelvic reference points. Results In 11 patients (7 of them treated in the SIGMA-60 and 4 in the SIGMA- Eye applicator) the measured treatment variables (SAR, temperatures in the pelvic reference points) indicated that the heated volumes were higher for the SIGMA-Eye applicator. The mean computed abdominal SARs were less for the SIGMA-Eye (33 versus 44 W/kg). Nevertheless, the temperature distributions in the abdomen (peritoneal cavity) were more homogeneous in the SIGMA-Eye applicator as compared to the SIGMA-60 as indicated by higher values of T 90 (mean 40.2 versus 38.2 °C) and T 50 (mean 41.1 versus 40.2 °C), while the maximum temperatures were similar (in the range 41 to 43 °C). Even though the mean abdominal SAR was lower in the SIGMA-Eye, the heat distribution covered a larger volume of the abdomen (in particular the upper abdomen). For the SIGMA-60 applicator the achieved T 90 appeared to be limited between 41 and 42 °C, for the SIGMA Eye applicator more effective T 90 in the range 42 to 43 °C were obtained. Conclusion Our results suggest that an adequate heating of the abdomen and therefore abdominal regional hyperthermia in PC patients appears feasible. The SIGMA-Eye applicator appears to be superior compared to the SIGMA-60 applicator for abdominal hyperthermia.

description: Background Aging and latent infection with Cytomegalovirus (CMV) are thought to be major factors driving the immune system towards immunosenescence, primarily characterized by reduced amounts of naïve T-cells and increased memory T-cells, potentially associated with higher morbidity and mortality. The composition of both major compartments, γδ as well as αβ T-cells, is altered by age and CMV, but detailed knowledge of changes to the γδ subset is currently limited. Results Here, we have surveyed a population of 73 younger (23–35 years) and 144 older (62–85 years) individuals drawn from the Berlin Aging Study II, investigating the distribution of detailed differentiation phenotypes of both γδ and αβ T-cells. Correlation of frequencies and absolute counts of the identified phenotypes with age and the presence of CMV revealed a lower abundance of Vδ2-positive and a higher amount of Vδ1-positive cells. We found higher frequencies of late-differentiated and lower frequencies of early-differentiated cells in the Vδ1+ and Vδ1-Vδ2-, but not in the Vδ2+ populations in elderly CMV-seropositive individuals confirming the association of these Vδ2-negative cells with CMV-immunosurveillance. We identified the highest Vδ1:Vδ2 ratios in the CMV-seropositive elderly. The observed increased CD4:CD8 ratios in the elderly were significantly lower in CMV-seropositive individuals, who also possessed a lower naïve and a larger late-differentiated compartment of CD8+ αβ T-cells, reflecting the consensus in the literature. Conclusions Our findings illustrate in detail the strong influence of CMV on the abundance and differentiation pattern of γδ T-cells as well as αβ T-cells in older and younger people. Mechanisms responsible for the phenotypic alterations in the γδ T-cell compartment, associated both with the presence of CMV and with age require further clarification.
