HLA-DR Marks Recently Divided Antigen-Specific Effector CD4 T Cells in Active Tuberculosis Patients.

Upon Ag encounter, T cells can rapidly divide and form an effector population, which plays an important role in fighting acute infections. In humans, little is known about the molecular markers that distinguish such effector cells from other T cell populations. To address this, we investigated the molecular profile of T cells present in individuals with active tuberculosis (ATB), where we expect Ag encounter and expansion of effector cells to occur at higher frequency in contrast to -sensitized healthy IGRA individuals.

Molecular Signatures of Dengue Virus-Specific IL-10/IFN-γ Co-producing CD4 T Cells and Their Association with Dengue Disease.

Dengue virus (DENV) can cause diseases ranging from dengue fever (DF) to more severe dengue hemorrhagic fever/dengue shock syndrome (DHF/DSS). Whether antiviral T cells contribute to the protection against or pathogenesis of severe disease is not well defined. Here, we identified antigen-specific IL-10IFN-γ double-positive (DP) CD4 T cells during acute DENV infection.

Dengue-specific CD8+ T cell subsets display specialized transcriptomic and TCR profiles.

Accumulating evidence demonstrates that CD8+ T cells contribute to protection from severe dengue virus (DENV) disease and vaccine efficacy. Nevertheless, molecular programs associated with DENV-specific CD8+ T cell subsets have not been defined. Here, we studied the transcriptomic profiles of human DENV-specific CD8+ T cells isolated after stimulation with DENV epitopes from donors who had been infected with DENV multiple times and would therefore be expected to have significant levels of adaptive immunity.

Population genetic data for ten miniSTR loci in the Sri Lankan population.

Allele frequencies and forensically important parameters of ten autosomal miniSTR loci, D1S1677, D2S1776, D10S1248, D11S4463, D12SATA, D14S1434, D17S974, D18S853, D20S482, and D22S1045, were obtained for 278 unrelated adults from the Sri Lankan population. The combined power of discrimination and probability of exclusion was found to be 0.999999999621539 and 0.
