Immune Response toward Mycobacterium Tuberculosis Infection
Authors: Ikram Hasanuddin Abdi Dzul , Roswita Nanang , Virnanda Amu Ivan
Published: August 2020

Understanding the human immune response toward Mycobacterium tuberculosis infection is important for controlling its infection. Its transmission through the air consists of "droplets nuclei" containing TB bacilli. After initial infection, the human body will provide diverse immune responses and will determine different clinico-histopathologic finding. This response starts from innate immunity that consists of phagocytosis by distal alveolar macrophages or nasal microfold cells, then will be continued by dendritic cells to be transferred to mediastinal lymph nodes to induced adaptive immune responses. This response is mediated by cells through IFN- γ signaling which will enhance phagocytosis. If this response is effective, there will be a latent infection with an initial histopathological finding of caseosa granulomas and predominantly followed by chronic granulomas. In a few cases, it can be reactivated via the IL-10 activation pathway and exogenous factors, it will induce a great adaptive immune reaction and provide more severe clinico-histopathological manifestation. The existence of the human body's immune response to Mycobacterium tuberculosis, etiher innate or adaptive immunity will determine the clinical course and pathology that will occur.

Published: September 2020

Ingestion of abnormal materials by cetaceans has been reported worldwide, but few studies have investigated the causes of foreign material ingestion. We retrospectively analysed necropsies performed between 2012 and 2019 on 88 cetaceans stranded along the coast of Catalonia, Spain, and evaluated the association of abnormal ingested materials with 2 risk factors, namely disease of the central nervous system (CNS) and maternal separation. Abnormal materials were found in the digestive tract in 19 of 88 (21.6%) cetaceans; of these, 13 (60%) had lesions in the CNS, such as morbilliviral encephalitis, neurobrucellosis or encephalomalacia, and 3 were diagnosed as having experienced maternal separation. In a logistic regression model, CNS lesions and maternal separation were identified as risk factors for ingestion of foreign material, but with wide confidence intervals, probably due to the small sample size. In contrast, abnormal ingestion was not identified in any of the 25 (28%) cetaceans whose cause of death was attributed to interaction with humans. Abnormal ingestion should be interpreted with caution, and efforts should be made at necropsy to exclude CNS diseases through pathologic and microbiologic investigations. If disease of the CNS is a significant risk factor for ingestion of marine debris by small odontocetes, results of monitoring programmes may be biased by the prevalence of CNS disease in a specific area or population.

Published: September 2020

This is the first report of betanodavirus infection in 2 species of finfish, Kuhlia rupestris (jungle perch) and Ambassis marianus (estuary perchlet). This report also describes isolation of betanodavirus from infected pond water using the SSN-1 cell line. Histopathology of K. rupestris larvae revealed vacuolation in the eye and brain, which was confirmed using betanodavirus-specific immunohistochemistry. The eye and brain from A. marianus and betanodavirus isolated from pond water were confirmed using real-time PCR and Sanger sequencing. High throughput sequencing was used to obtain betanodavirus sequences from paraffin blocks containing infected K. rupestris. The phylogenetic analysis of betanodavirus RNA1 and RNA2 sequences from all 3 sources were associated with the red-spotted grouper nervous necrosis virus (RGNNV) genotype. The RNA1 nucleotide sequence from jungle perch showed 100% identity with the betanodavirus water isolate and 99.37% identity with A. marianus. Furthermore, we have demonstrated the usefulness of combining recovery of viable virus from environmental samples through fish cell line culture with PCR testing as a means of validating the efficacy of chlorination to eradicate betanodavirus from the pond environment.

Published: September 2020

Results of the work on the synthesis of highly effective nanocomposite platinum-containing oxygen reduction electrocatalysts for hydrogen-oxygen fuel cells are presented and ways of increasing their activity are considered. Fuel cells (FCs) represent the most promising renewable and environmentally friendly energy sources that can operate at low temperatures with high efficiency and with low or zero levels of hazardous waste. The main problem of fuel cells is that the oxygen reduction reaction is slowed down in relation to the hydrogen oxidation reaction, which leads to an increase in the overvoltage at the cathode and, as a result, to a decrease in the productivity of FCs. To solve this problem, the new methods are being developed for the synthesis of highly efficient platinum electrocatalysts, which currently have the best performance, since platinum has the highest specific catalytic activity among other materials used in low temperature FCs. The purpose of this work is to determine the optimal composition of reaction mixture and conditions for the preparation of a platinum based catalyst for oxygen electroreduction where Vulcan XC-72 nanodispersed carbon black is used as a carrier. We have worked out 6 methods for preparing Pt  (40 %)/XC-72 catalysts. To evaluate the activity of the prepared catalysts and to determine the kinetic parameters of the oxygen reduction on them, cathodic stationary polarization curves were recorded in a 0.5 M H2SO4 solution on a floating gas diffusion electrode superficially modified by the catalysts. For preparation of all electrocatalysts we are used 3.6 ml of a hexachloroplatinic acid (H2PtCl6) solution, containing 18.8 mg Pt/ml, 100 ml of ethylene glycol or its mixture with deionized water (3 : 1) and 100 mg of Vulcan XC-72 carbon black, previously oxidized in HNO3 solution. 1 M NaOH or KOH solutions were used to create the necessary medium (pH = 11). Some Pt(40 %)/XC-72 electrocatalysts were prepared when additions of polyvinylpyrrolidone (PVP) (100 mg or 300 mg) and/or 60 ml of formaldehyde were introduced into reaction mixture. Temperature during syntheses was in the range 75 - 160 °C. It was shown that reducing the synthesis temperature from 160 to 75 °C and introduction of PVP together with formaldehyde into reaction mixture had a positive effect on the activity of obtained nanocomposite platinum-containing catalysts Pt(40 %)/XC-72 for oxygen electroreduction.The sizes of the obtained platinum clusters on the surface of carbon black nanoparticles were in the range of 1.7 - 5.7 nm, and under optimal synthesis conditions they were evenly and densely distributed on the surface of the carbon carrier. The obtained kinetic characteristics of oxygen electroreduction on the studied catalysts indicate that the mechanism of this process depended on both the current density and the method of catalyst synthesis.

Published: September 2020

Aim: To describe the development and outcomes of a rehabilitation intervention for persons with Parkinson’s and their near-ones. Material and methods: Customer-understanding-based intervention development; and a pilot study: a random sample of persons with PD (n=18) and their near-ones (n=7) were divided into subgroups: Persons with PD, Gym rehabilitation; Persons with PD, Home rehabilitation; Near-ones, Gym rehabilitation; Near-ones, Home rehabilitation. Data included clinical measurements, scores from a PDQ-39 questionnaire and a simple diary, analyzed with descriptive statistics. Results: The PISER intervention was established to be feasible in relation to study and data collection procedures, outcome measures and to recruitment of persons with PD. After the eight-week intervention, both Persons with PD subgroups and Near-ones in Gym group had better clinical outcomes and better emotional, social and communicative health-related quality of life. Near-ones, Home rehabilitation had marginally poorer clinical outcomes, but still reported better cognitive well-being. Conclusions: The PISER intervention was shown to be feasible. By engaging in systematic physical activity, persons with PD and near-ones maintained or developed their functional capacity, psychosocial well-being and certain aspects of health-related quality of life. An eight-week rehabilitation intervention had a positive impact on self-management, especially in gym-groups, in which the participants enjoyed the social aspects of group rehabilitation and received individual instruction and feedback during physical activity. This kind of person-centered, systematic physical activity intervention may prevent inactivity and fall risks, and delay onset of activity limitations. It is vital that healthcare professionals and clients with PD together analyze and discuss the meaning of physical activity and self-rehabilitation.

Prioritizing Facilitators for Successful Implementation of PBSS in Indian Urban Areas Using BWM Method
Authors: Patel Samir Jayprakash , Patel Chetankumar Ramanlal
Published: August 2020

The demand for mobility is increasing day by day along with the rise in population. In the absence of clear guidelines and policy regarding the use of shared transport or Mass transportation, the use of personalized vehicles has grown rapidly. The personal vehicle owned individually, in which one cannot use others even belonging to the same family this leads to more traffic on the road. This leads to more consumption of fossil fuel and responsible for climate change. The Public Bicycle Sharing System (PBSS) is the concept, based on shared mobility in which users enable to use it for short-distance trips and drop it at any location through check-in/check-out operations without any accountability and likewise anyone can again use it with the same procedure. These multiple uses of the system conserve natural resources and increase the national economy by reducing the consumption of fossil fuel for mobility. The PBSS in urban areas, normally used for short-haul trips. However, by integrating it into public transport, the coverage of PT may also be increased, which attracts more users. In India implementation of this system is introduced in mid-2017 at Bhopal and within the short span, nearly 14 cities adopted PBSS in their urban areas. However, the majority of the system presently facing ridership issues due to the absence of bicycle-friendly infrastructure. Hence, it is essential to overcome such barriers using an appropriate facilitator. The BWM approach used in this study identifies the top facilitators based on the expert opinion survey to implement PBSS successfully. The result of this study shows that city infrastructure facilitators, technological facilitators, as well as a dedicated bicycle lane, government policy are the most effective facilitators which can improve the ridership and promote a circular economy through shared mobility. This study will help the decision-makers in developing the facilitator and enhance the ridership of PBSS.

Published: August 2020

Analytical expressions are used frequently for the determination and analysis of plasma parameters. Instead of relying on analytical expressions, the proposed method uses regression techniques supplemented with experimental data for the selected parameters (plasma potential). In the machine learning domain, this is equivalent to the creation of the training data set, building and training the model, and authenticating the result over a range of desired physical parameters. An experimental dataset is built using two axially movable Triple Langmuir Probe (TLPs) which measure the electron temperature, electron density, and electric potential of a plasma. The presented work is a first step towards developing an inclusive model with detailed kinetic simulations capable of characterizing the HELicon Experiment for Negative ion source (HELEN-I) with a single driver. Plasma potential is measured at different axial locations (z) by keeping pressure fixed at 6 mTorr.

Published: August 2020

When it comes across problems in creating Internet of Things (IOT) architecture, the major problem that arises is an automatic stipulation of resources. At the same time in today’s era, it is very important to integrate this problem with better Quality of Services (QoS) because of which the cloud computing is taking a shift. As being well acquainted that in fog computing, network’s bandwidth is limited, therefore it becomes quite important to build a joint architecture with resource allocation problem giving it a better quality of services with enhanced efficiency and low latency communication. Priority of QoS is determined by Systematic Ladder Process (SLP) and decision parameter evaluation by RECK algorithm. In this paper, there will be a design of a better framework for IOT resource allocation scheme with better efficiency and better QoS. The paper too highlights the comparison of the previous works of the resource allocation algorithms and schemes with RECK algorithm.

Existing approaches to formation of quantitative indicator of resilience of objects of different complexity operating under conditions of external impacts are discussed. Advantages and disadvantages of approaches under discussion are specified. As general basis for application of resilience concept, the class of so-called target-driven systems oriented to achieving some preset target in a certain period is marked out. It is proposed to use the value of the indicator constructed using methodical apparatus "difficulties of achieving target" of I. B. Russman for quantitative assessment of resilience of similar systems. Methods of calculation and results of model assessments of resilience using this approach are presented. Directions of Russman’s approach development are proposed based on application of so-called method of trajectory analysis of behavior of target-driven systems, described by dynamics of integral indicator characterizing object of study in coordinates of rate and acceleration of its changes.
A Two-Stage Mutation Stochastic Model of Carcinogenesis Driven by a Three Level Environmental Process
Authors: Yadavalli V. S. S. , Udayabaskaran S. , Pravina C. T. Dora , Sreelakshmi S.
Published: August 2020

A two-mutation model of carcinogenesis which evolves under the influence of three level random environment on the production process is formulated and analyzed. A random environment occupies one of the levels 1, 2 and 3 at any time t according to a Markov process. When the environment is in level 1, a normal cell either divides into two normal cells or dies; and an intermediate cell divides into two intermediate cells or dies. When the environment is in level 2, a normal cell either divides into one normal cell and one intermediate cell or dies and an intermediate cell either divides into one intermediate cell and one malignant cell or dies. When the environment is in level 3, a normal cell either divides into two intermediate cells or dies and an intermediate cell either divides into two malignant cells or dies. It is assumed that, once a malignant cell is produced, it generates a malignant tumor with probability 1. We obtain the mean numbers of normal, intermediate and malignant cells at any time t.
Finding Top-k Nodes for Temporal Closeness in Large Temporal Graphs
Authors: Crescenzi Pierluigi , Magnien Clémence , Marino Andrea
Published: August 2020

The harmonic closeness centrality measure associates, to each node of a graph, the average of the inverse of its distances from all the other nodes (by assuming that unreachable nodes are at infinite distance). This notion has been adapted to temporal graphs (that is, graphs in which edges can appear and disappear during time) and in this paper we address the question of finding the top-k nodes for this metric. Computing the temporal closeness for one node can be done in O(m) time, where m is the number of temporal edges. Therefore computing exactly the closeness for all nodes, in order to find the ones with top closeness, would require O(nm) time, where n is the number of nodes. This time complexity is intractable for large temporal graphs. Instead, we show how this measure can be efficiently approximated by using a “backward” temporal breadth-first search algorithm and a classical sampling technique. Our experimental results show that the approximation is excellent for nodes with high closeness, allowing us to detect them in practice in a fraction of the time needed for computing the exact closeness of all nodes. We validate our approach with an extensive set of experiments.
Core Self-Evaluations, Self-Leadership, and the Self-Serving Bias in Managerial Decision Making: A Laboratory Experiment
Authors: Cristofaro Matteo , Giardino Pier Luigi
Published: September 2020

The self-leadership construct has received great attention from scholars over the last 40 years due to its capacity to influence personal effectiveness. However, despite strongly influencing individuals’ self-efficacy, performed studies did not determine whether self-leadership is connected, and how, with the Core-Self Evaluation (CSE) trait—a complex personality disposition based on self-efficacy, self-esteem, locus of control, and emotional stability—that has been found impacting decision-making processes within organizations. Moreover, it has not been identified whether individuals with a high level of self-leadership are more prone to be victims of some cognitive biases in decision-making processes, such as the internal attribution of successes and external attribution of failures (i.e., Self-Serving Bias, SSB) that are usually led by the strong belief of individuals in their own capacities. The outlined gaps can be substantiated by the following two research questions: “How is self-leadership related with CSE?” and “How does self-leadership influence the attribution of successes/failures?”. To answer these questions, the following were identified and analyzed for 93 executives: (i) the tendency in the attribution of successes and failures, (ii) the CSE, and (iii) their self-leadership level. Results show that: (i) a high level of CSE is connected with high levels of self-leadership; (ii) high levels of self-leadership bring individuals to the internal attribution of successes and external attribution of failures. This work reinforces the stream of (the few) studies that considers a high level of CSE and self-leadership as not always being desirable for managerial decision-making processes and consequent performance. This paper aims to enrich the debate concerning the relations between, on the one hand, self-leadership and, on the other hand, personality traits between self-leadership and decision making.
Real Time Measurement of Airplane Flutter via Distributed Acoustic Sensing
Authors: Bakhoum Ezzat G. , Zhang Cheng , Cheng Marvin H.
Published: August 2020

This research group has recently used the new technology Distributed Acoustic Sensing (DAS) for the monitoring and the measurement of airplane flutter. To the authors’ knowledge, this is the first such use for this new technology. Traditionally, the measurement of airplane flutter requires the mounting of a very large number of sensors on the wing being monitored, and extensive wiring must be connected to all these sensors. The new system and technology introduced in this paper dramatically reduces the hardware requirements in such an application: all the traditional sensors and wiring are replaced with one fiber optic cable with a diameter of 2 mm. An electro-optical system with the size of a desktop PC monitors simultaneously one or more of such fiber optic cables and detects/characterizes any mechanical disturbances on the cables. Theoretical and experimental results are given.

Published: September 2020

The largest group of cabbage plant pests are the species in the owlet moth family (Lepidoptera: Noctuidae), the most dangerous species of which is the cabbage moth (Mamestra brassicae L.). In cases of heavy infestation by this insect, the surface of plants may be reduced to 30%, with a main yield loss of 10–15%. The aim of the present study was to assess the susceptibility of M. brassicae larvae to nine native nematode isolates of the species Steinernema feltiae (Filipjev) and Heterorhabditis megidis Poinar, Jackson and Klein under laboratory conditions. The most pathogenic strains were S. feltiae K11, S. feltiae K13, S. feltiae ZAG11, and S. feltiae ZWO21, which resulted in 100% mortality at a temperature of 22 °C and a dosage of 100 infective juveniles (IJs)/larva. The least effective was H. megidis Wispowo, which did not exceed 35% mortality under any experimental condition. For most strains, there were significant differences (p ≤ 0.05) in the mortality for dosages between 25 IJs and 50 IJs, and between 25 IJs and 100 IJs, at a temperature of 22 °C. Statistical analysis of the effect of temperature on mortality showed that only strain H. megidis Wipsowo exhibited significant differences (p ≤ 0.05) when applied at dosages of 50 IJs and 100 IJs.
How Can Weedy Rice Stand against Abiotic Stresses? A Review
Authors: Fogliatto Silvia , Ferrero Aldo , Vidotto Francesco
Published: August 2020

Weedy rice is one of the most common weeds in rice cultivation in many rice areas throughout the world and it is able to cause significant yield reductions. Weedy rice is characterized by a high biological diversity that permits different populations to be identified on the basis of their morphological and physiological traits. This variability contributes to its success in different environments and allows different abiotic stresses, which are intensified by climate change, to be faced. Taller plants, enhanced tillering, seed shattering and the presence of red pericarp, variable hull coloration and awn morphology, linked to a deeper seed dormancy, are some of the traits that help weedy rice to spread in changing environments. The higher phenotypic plasticity and genetic variability of weedy rice make it more able to cope with temperature variations, intermittent water availability, soil salinity, drought conditions and increased CO2 concentrations than cultivated rice. As these abiotic stresses will become more frequent in the future, weedy rice competitiveness may be higher, with a spread of infestations. Thus, the control of weedy rice should be based on an integration of different preventive and agronomic techniques, a sensible use of herbicides and the use of suitable rice varieties.

Leaf rust (LR) and stem rust (SR) pose serious challenges to wheat production in Kazakhstan. In recent years, the susceptibility of local wheat cultivars has substantially decreased grain yield and quality. Therefore, local breeding projects must be adjusted toward the improvement of LR and SR disease resistances, including genetic approaches. In this study, a spring wheat segregating population of Pamyati Azieva (PA) × Paragon (Par), consisting of 98 recombinant inbred lines (RILs), was analyzed for the resistance to LR and SR at the seedling and adult plant-growth stages. In total, 24 quantitative trait loci (QTLs) for resistance to rust diseases at the seedling and adult plant stages were identified, including 11 QTLs for LR and 13 QTLs for SR resistances. Fourteen QTLs were in similar locations to QTLs and major genes detected in previous linkage mapping and genome-wide association studies. The remaining 10 QTLs are potentially new genetic factors for LR and SR resistance in wheat. Overall, the QTLs revealed in this study may play an important role in the improvement of wheat resistance to LR and SR per the marker-assisted selection approach.

Published: August 2020

The aim of this study was to analyse the genetic and phenotypic differentiation of bacteria isolated from root nodules of Trifolium rubens, a rare clover species. The symbiotic compatibility of selected isolates was investigated using two agronomically important plants, red clover (Trifolium pratense L.) and pea (Pisum sativum L.). A high genetic diversity of analysed strains was shown using the Enterobacterial Repetitive Intergenic Consensus Polymerase Chain Reaction (ERIC-PCR) method. Most of the strains showed a high similarity to R. leguminosarum in the 16S rRNA sequence. Two strains were identified as Agrobacterium spp. There was a strong positive correlation between fresh clover weight and the number of root nodules and a statistically significant increase in the number of the root nodules in selected strains compared to the negative control. Phenotypic tests and BIOLOG analysis showed the ability of the analysed strains to grow in different experimental conditions (pH = 6–10, 0.5–3% NaCl, different carbon and nitrogen sources), which makes them suitable for application as an agronomically important factor.
Survey on Sheep Usage in Biomedical Research
Authors: Berset Corina Mihaela , Lanker Urban , Zeiter Stephan
Published: August 2020

Currently, there is a lack of detailed information about sheep used for biomedical research. Therefore, a European survey was conducted among sheep users gathering information on the current situation, with emphasis on animal selection criteria and issues encountered in practice. The ultimate goal was to identify needs for improvement, which will subsequently lead to a refinement and reduction of the total number of animals used for experimental studies. From the 84 respondents, 77.4% were veterinarians, 71.4% were employed at academic institutions and 63.1% had worked with sheep as research animals for more than 5 years. The majority of the respondents were using females (79.8%) with no clear age preference, mainly for surgical procedures and testing medical devices. The main criteria for choosing a sheep supplier were the animals’ health status, their availability, the trust and experience in the sheep provider and the animals’ uniformity. Approximately 60% of the respondents had encountered problems in their sheep not related to the experimental protocol and almost half of them did not have a health monitoring program for their animals. In conclusion, there is definitely a need for refinement in selecting sheep used in biomedical research, with their health status as possible starting point.
The Contribution of Mutual Grooming to Affiliative Relationships in a Feral Misaki Horse Herd
Authors: Shimada Masaki , Suzuki Nae
Published: September 2020

Although herd size, structure, stability, and social rank among Misaki feral horses have been reported, no studies have been conducted on the affiliative relationships and interactions among members in a Misaki horse herd. The validity of three hypotheses regarding the function of social grooming, the affiliative relationship strengthening hypothesis, the worsened relationship restoring hypothesis, and the grooming parasite removal hypothesis, were tested in a Misaki feral horse (Equus caballus) herd in Cape Toi, Japan. All the nine horses in the “6m” herd were investigated in terms of kinship, grooming, aggression, proximity, social rank, and social network. Mutual grooming occurred only in pairs and was almost perfectly symmetrical. For each member, there was a significant negative correlation between total grooming received from other individuals and self-grooming. Controlling for kinship, there were significant positive partial correlations between mutual grooming and proximity and between aggression and proximity. No correlation was observed between aggression and mutual grooming. The results suggest that mutual grooming symmetry may contribute that both participants simultaneously benefit from parasite removal and strengthen affiliative relationships between seasonally changing herd members; however, mutual grooming did not foster restoring the worsened relationship following aggression promoted by physical proximity. The findings of this study may elucidate the mechanisms by which interactions between herd members are maintained or strengthened.
Beneficial Land Management for Hedgehogs (Erinaceus europaeus) in the United Kingdom
Authors: Yarnell Richard W. , Pettett Carly E.
Published: September 2020

Hedgehogs (Erinaceus europaeus) are traditionally thought of as being a rural dwelling species, associated with rural and agricultural landscapes across Europe. However, recent studies have highlighted that hedgehogs are more likely to be found in urban than rural habitats in the United Kingdom. Here, we review the status of rural hedgehog populations across the UK and evaluate the potential benefits of agri-environment schemes for hedgehog persistence, while highlighting a lack of empirical evidence that agri-environment options will benefit hedgehog populations. Our synthesis has implications for future conservation strategies for hedgehogs and insectivorous mammals living in agricultural landscapes, and calls for more empirical studies on agri-environment options and their potential benefits to hedgehogs.

(1) Background: Under practical conditions, newly hatched chicks were usually withheld feed and water for 48 to 72 h. It was shown that early feeding after hatch promoted gastrointestinal development of broiler chicks. However, the mechanism of early feeding affecting intestinal development in chicks needs further research. The present study was conducted to investigate the effects of first feed administration on intestinal morphology, barrier function, and plasma hormones in broilers during the initial 168 h posthatch. (2) Methods: A total of 720 one-day-old chicks (newborn chick, Lingnan Yellow) were placed 2 h after hatch and randomly assigned to three treatments: Group A (feed immediately after placement), Group B (fasting for 24 h after placement), and Group C (fasting for 48 h after placement). The trial lasted for 168 h and water ad libitum all the time. Sampling was performed at 0, 24, 48, 72, 120, and 168 h. (3) Results: Higher (p < 0.05) absolute weight and relative weight of the small intestine were observed in Group A. Moreover, the villus height, crypt depth, and ratio of the jejunum and ileum were significantly higher (p < 0.05) in Groups A and B than those in Group C. Microvilli of the duodenum were closely packed in Group A but sparse and disorganized in Groups B and C. The expression levels of mRNA and protein of tight junction genes (occludin and claudin-1) were upregulated (p < 0.05) in Group A. The levels of gastrin and insulin in plasma were decreased (p < 0.05) significantly in the Groups B and C. However, chicks in Groups B and C had higher (p < 0.05) plasma glucagon levels at 24 and 48 h after placement. (4) Conclusions: These results suggested that early feeding posthatch had a positive effect on small intestinal growth increasing weight and improving intestinal morphology and barrier function.
Antibiotics Differentially Modulate Lipoteichoic Acid-Mediated Host Immune Response
Authors: Algorri Marquerita , Wong-Beringer Annie
Published: September 2020

In Staphylococcus aureus bacteremia, our group has shown that a dysregulated balance of pro- and anti-inflammatory cytokine response biased towards an immunoparalysis phenotype is predictive of persistence and mortality, despite receipt of antibiotics. Certain antibiotics, as well as lipoteichoic acid (LTA) released from S. aureus, can modulate immune response ex vivo. Here, we evaluated the effects of three anti-staphylococcal antibiotics (vancomycin, tedizolid, and daptomycin) on the expression of cytokines and cell surface markers of immune activation (TNFα, HLA-DR) and immunoparalysis (IL-10, PD-L1) in human peripheral blood mononuclear cells (PBMC) exposed to high (10 μg) and low (1 μg) doses of LTA. Results suggested a dose-dependent relationship between LTA and induction of anti- and pro-inflammatory immune responses. Differential antibiotic effects were prominently observed at high but not low LTA condition. Vancomycin significantly induced IL-10 and TNFα expression, whereas daptomycin had no effects on cytokine response or expression of cell surface receptors. Tedizolid increased TNFα and modestly increased HLA-DR expression, suggesting a stimulatory effect. These findings suggest that anti-staphylococcal agents differentially alter LTA-mediated immune cell activation status and cytokine response, providing support for future clinical studies to better elucidate the complexities of host–microbial–antibiotic interaction that can help direct precision therapy for S. aureus bacteremia.
