Expression of CD57 by CD8+ and CD4+ T cells derived from the cervix and blood of HIV+ and HIV− women. (A) Representative plots showing the frequency of CD57 expression by blood (left panels) and cervical (right panel) CD8+CD3+ (top panels) and CD4+CD3+ (lower panels) T cells. (B) We compared the frequency of CD57+ expression by CD8+CD3+ (upper panel) and CD4+CD3+ (lower panel) T cells in blood and cervical T cells from HIV− (n = 5) and HIV+ (n = 13) women. Each dot represents an individual woman's CD57 frequency and lines joining dots indicate matched blood and cervical frequencies in individual woman. Paired Student's t-test was used to compare CD57 expression frequencies in blood and at the cervix. An unpaired Student's t-test was used to compare CD57 expression frequencies in HIV+ and HIV− women. (C) Association between the frequency of CD57 expression by cervical and blood-derived CD8+CD3+ (left panel) and CD4+CD3+ (right panel) T cells. Regression lines and Pearson R-values are shown for correlations. p-values ≤ 0.05 were considered significant.
