Abstract
The frequency of cytomegalovirus (CMV)-specific CD4+ T lymphocytes was determined in CMV-seropositive rhesus macaques with or without simian immunodeficiency virus (SIV) infection by using the sensitive assays of intracellular cytokine staining and gamma interferon ELISPOT. Both techniques yielded 3- to 1,000-fold-higher frequencies of CMV-specific CD4+ T lymphocytes than traditional proliferative limiting dilution assays. The median frequency of CMV-specific CD4+ T lymphocytes in 23 CMV-seropositive SIV-negative macaques was 0.63% (range, 0.16 to 5.8%). The majority of CMV-specific CD4+ T lymphocytes were CD95(pos) and CD27(lo) but expressed variable levels of CD45RA. A significant reduction (P
