Mobilizing Subdominant Hiv-Specific Ctls As A Novel Vaccine Strategy, Margaret Christina Costanzo

Open Access Theses & Dissertations

To overcome the extreme antigenic diversity of HIV, there is increasing interest in developing vaccines that target CD8 T cell responses to conserved regions of the viral proteome. Understanding the immunogenic potential of these domains is therefore critical for the success of this vaccine strategy. CD8 T cell responses to conserved domains restricted by the "neutral" and highly prevalent HLA-A2 allele have not been extensively characterized. Here we describe a novel essentially invariant 10-mer epitope in HIV Gag (p2414-23, RTLNAWVKVV (RV10)) in that it is expressed by the majority HIV isolates from all clades. Here we examined the character of …
