BACKGROUND Timely access to antiretroviral therapy is a key to controlling HIV infection. Late diagnosis and presentation to care diminish the benefits of antiretrovirals and increase risk of transmission. We aimed to identify late presenters in patients sent for first CD4 T cell count after HIV diagnosis, for therapy initiation evaluation. Further we aimed(More)
BACKGROUND & OBJECTIVES DCs trigger both innate and adaptive immune responses to control HIV infection and represent a viral reservoir acting as target and HIV carriers for infection of permissive CD4(+) T-cells. DCs thus form a very attractive study subject to further our existing knowledge of HIV induced immunopathogenesis due to its diverse and crucial(More)
Cytotoxic T lymphocyte (CTL) responses to Gag have been most frequently linked to control of viremia whereas CTL responses to Nef have direct relationship with viral load. IFN-γ ELISpot assay was used to screen CTL responses at single peptide level directed at HIV-1 subtype C Gag and Nef proteins in 30 antiretroviral therapy naive HIV-1 infected Indian(More)
Polyfunctional CD8+ T-cells have been described as most competent in controlling viral replication. We studied the impact of antigen persistence on the polyfunctional immune responses of CD8+ T-lymphocytes to HIV Gag and Nef peptides and polyclonal stimuli in 40 ART naïve HIV infected individuals and analyzed the alterations in T-cell functionality in early(More)
Methods Multiparametric flow cytometry and intracellular cytokine staining was performed to study the effect of HAART on poly functional responses of CD8+ T lymphocytes to HIV Gag and Nef peptides and polyclonal stimuli in 40 ART naïve and 10 ART treated HIV infected individuals to compare and examine the degree of immune restoration after ART. We analyzed(More)
