The immune system has evolved to become highly specialized in recognizing and responding to pathogens and foreign molecules. Specifically, the function of HLA class II is to ensure that a sufficient sample of peptides derived from foreign molecules is presented to T cells. This leads to an important concern in human drug development as the possible(More)
BACKGROUND Epitope vaccines have been suggested as a strategy to counteract viral escape and development of drug resistance. Multiple studies have shown that Cytotoxic T-Lymphocyte (CTL) and T-Helper (Th) epitopes can generate strong immune responses in Human Immunodeficiency Virus (HIV-1). However, not much is known about the relationship among different(More)
BACKGROUND Studies have shown that in the genome of human immunodeficiency virus (HIV-1) regions responsible for interactions with the host's immune system, namely, cytotoxic T-lymphocyte (CTL) epitopes tend to cluster together in relatively conserved regions. On the other hand, "epitope-less" regions or regions with relatively low density of epitopes tend(More)
We performed a quantitative analysis of the HLA restriction, antigen and epitope specificity of human pathogen specific responses in healthy individuals infected with M. tuberculosis (Mtb), in a South African cohort as a test case. The results estimate the breadth of T cell responses for the first time in the context of an infection and human population(More)
Accurate measurement of B and T cell responses is a valuable tool to study autoimmunity, allergies, immunity to pathogens, and host-pathogen interactions and assist in the design and evaluation of T cell vaccines and immunotherapies. In this context, it is desirable to elucidate a method to select validated reference sets of epitopes to allow detection of T(More)
Computational prediction of HLA class II restricted T cell epitopes has great significance in many immunological studies including vaccine discovery. With the development of novel bioinformatics approaches, prediction of HLA class II binding has improved significantly but a strategy to predict the most dominant HLA class II epitopes has not been defined.(More)
Human Immunodeficiency Virus (HIV-1), one of the fastest evolving organisms, is a leading cause of death in the world today. But regardless of isolated stories about HIV cure in one patient and a modest success in a clinical vaccine trial, a perfect vaccine that can give total protection or a drug for a complete cure still remains intangible. Epitope(More)
