Randomized trial examines CTL responses across HIV-1 clades in different populations, suggesting cross-immunity potential.

This research aims to investigate how variability among HIV-1 subtypes affects CTL responses in different patient populations.
Analyzed protein sequences of HIV-1 Env and Gag from patients in France and Africa.
Tested CTL responses against target cells expressing proteins from HIV-1 clades A and B, as well as HIV type 2.
All African patients were mainly infected with clade A viruses, while French patients were infected with clade B.
Frequent cross-reactions of CTLs with proteins from different clades were observed.
Conserved epitopes in Gag proteins were particularly noted for their cross-reactivity.

Duralı et al. (1998) studied this question.
