Abstract
Individuals infected with different subtypes of HIV-1 (A, B, C, D, CRF01_AE and CRF02_AG) were analyzed for their antigen-specific immune response with respect to their HLA genetics. The p24 Gag protein was selected for analysis, since previous studies of the same cohort of patients had shown that almost 80% of these individuals responded to Gag peptides of subtypes A, B and/or C. A large number of Gag antigen-specific responses were recorded. Both previously recognized as well as new epitopes were identified, assumed to bind HLA classes I and/or II. Fifteen individuals showed class I cellular responses to T cell epitopes irrespective of the infecting virus subtype. For five individuals infected with subtypes A, B, D and CRF02_AG, new T cell epitopes are described. Responses related to the patient's class I alleles are frequent, and several new putative class II responses were found.Entities:
