In a longitudinal study of HIV seropositive patients, there were fluctuations in the specificity
of cytotoxic T cells for the virus. This was matched by variability in proviral gag DNA epitope
sequences in the lymphocytes of these patients. Some of these viral variants are not
recognized by autologous T cells. Accumulation of such mutations in T-cell antigenic targets
would provide a mechanism for immune escape.
