Fig. 3From: Increased inflammation but similar physical composition and function in older-aged, HIV-1 infected subjectsFrequency of CD45RO-expressing memory CD4+ T cells, but not CD57+ CD4+ T cells, is associated with CD4+ T cell decline. PBMC samples were analyzed by flow cytometry by first gating on the total mononuclear cells and then on the CD3+ T cells. The frequency of (a) CD4+ CD45RO+ T cells was then determined. The correlations between total peripheral blood CD4+ T cell counts and (b) T cells CD4+ CD45RO+ T cells, (c) CD4+ CD28+ CD57+ T cells, or (d) CD8+ CD28− CD57+ T cells were determined (Pearson correlation)Back to article page
