Abstract

Evaluation of: Pleguezuelos O, Stoloff GA, Caparros-Wanderley W. Synthetic immunotherapy induces HIV virus specific Th1 cytotoxic response and death of an HIV-1 infected human cell line through classic complement activation. Virol. J. 10(1), 107 (2013). AIDS vaccine development represents an unprecedented challenge in both immunogen design and delivery to induce potent and long-lasting HIV-specific immune responses, including neutralizing antibodies and cytotoxic T lymphocytes (CTL). Pleguezuelos and coworkers recognized that immunogen design must address both HIV and HLA diversity to make a global vaccine. The HIV-v synthetic polypeptide vaccine described here sets a new standard in antigen design by selecting conserved regions of global HIV-1 and HIV-2 isolates and epitopes from most frequent HLA types of the human population. The new vaccine induced both antibody and CTL responses. Importantly, the authors demonstrated vaccine-specific HLA restricted CD8(+) CTL responses for one HLA allele that was involved in the antigen design. HIV-v vaccine is a new candidate to be tested in human subjects carrying frequent HLA types.
