Abstract: Targeting of proteins to APCs is an attractive strategy for eliciting adaptive immune responses. However, the relationship between the choice of the targeted receptor and the quality and quantity of responses remains poorly understood. We describe a strategy for expression of Ags including hydrophobic proteins as soluble fusion proteins that are optimized for proteasome-dependent MHC class I-restricted cross-presentation and form stable complexes with a wide variety of targeting Abs. Upon s.c. immunization, these complexes were initially taken up by CD169+ lymph node subcapsular sinus macrophages. In the OVA model system, receptor-targeted antigenic complexes primed specific T and B cell responses in vitro and in vivo at least 100-fold more efficiently than Ag alone. Comparison of 10 targeting receptors allowed us to establish a ranking with respect to priming of CD8+ T cell responses and demonstrated striking differences with respect to the relative efficacy of CD8+ and CD4+ T cell subset and B cell priming. The described fusion proteins should help in developing optimized strategies for targeted delivery of protein Ags in the context of tolerization or vaccination..

Abstract: BACKGROUND Results of the few cohort studies from countries with low incomes or middle incomes suggest a lower incidence of dementia than in high-income countries. We assessed incidence of dementia according to criteria from the 10/66 Dementia Research Group and Diagnostic and Statistical Manual of Mental Disorders (DSM) IV, the effect of dementia at baseline on mortality, and the independent effects of age, sex, socioeconomic position, and indicators of cognitive reserve.
METHODS We did a population-based cohort study of all people aged 65 years and older living in urban sites in Cuba, the Dominican Republic, and Venezuela, and rural and urban sites in Peru, Mexico, and China, with ascertainment of incident 10/66 and DSM-IV dementia 3-5 years after cohort inception. We used questionnaires to obtain information about age in years, sex, educational level, literacy, occupational attainment, and number of household assets. We obtained information about mortality from all sites. For participants who had died, we interviewed a friend or relative to ascertain the likelihood that they had dementia before death.
FINDINGS 12,887 participants were interviewed at baseline. 11,718 were free of dementia, of whom 8137 (69%) were reinterviewed, contributing 34,718 person-years of follow-up. Incidence for 10/66 dementia varied between 182 and 304 per 1000 person-years, and were 14-27 times higher than were those for DSM-IV dementia (99-157 per 1000 person-years). Mortality hazards were 156-569 times higher in individuals with dementia at baseline than in those who were dementia-free. Informant reports suggested a high incidence of dementia before death; overall incidence might be 4-19% higher if these data were included. 10/66 dementia incidence was independently associated with increased age (HR 167; 95% CI 156-179), female sex (072; 061-084), and low education (089; 081-097), but not with occupational attainment (104; 095-113).
INTERPRETATION Our results provide supportive evidence for the cognitive reserve hypothesis, showing that in middle-income countries as in high-income countries, education, literacy, verbal fluency, and motor sequencing confer substantial protection against the onset of dementia.

question:
Abstract: Lipid droplets are ubiquitous triglyceride and sterol ester storage organelles required for energy storage homeostasis and biosynthesis. Although little is known about lipid droplet formation and regulation, it is clear that members of the PAT (perilipin, adipocyte differentiation related protein, tail interacting protein of 47 kDa) protein family coat the droplet surface and mediate interactions with lipases that remobilize the stored lipids. We identified key Drosophila candidate genes for lipid droplet regulation by RNA interference (RNAi) screening with an image segmentation-based optical read-out system, and show that these regulatory functions are conserved in the mouse. Those include the vesicle-mediated Coat Protein Complex I (COPI) transport complex, which is required for limiting lipid storage. We found that COPI components regulate the PAT protein composition at the lipid droplet surface, and promote the association of adipocyte triglyceride lipase (ATGL) with the lipid droplet surface to mediate lipolysis. Two compounds known to inhibit COPI function, Exo1 and Brefeldin A, phenocopy COPI knockdowns. Furthermore, RNAi inhibition of ATGL and simultaneous drug treatment indicate that COPI and ATGL function in the same pathway. These data indicate that the COPI complex is an evolutionarily conserved regulator of lipid homeostasis, and highlight an interaction between vesicle transport systems and lipid droplets..
