FIG. 4.
Plasmacytoid dendritic cells induce CLA expression by memory CD4 T cells responding to HSV-2 antigen. (A) Representative histograms showing CLA expression after exposure of the indicated cell populations, gated for CD4+ CFSElow lymphoblasts, to viral antigens or PHA. Either the whole PBMC (left) or purified CD4+ T cells were labeled with CFSE. (B) Means and standard deviations of CLA expression levels from triplicate assays for a representative subject. Mono, monocytes.
