Figure 2. Frequency of central memory or effector memory CD4+ cell subsets does not significantly vary between HIV susceptible, HIV not susceptible, and North American samples.
Frequency of CD45RO+CD27+ (central memory) and CD45RO+CD27− (effector memory) cells were determined after gating on viable CD3+CD4+ lymphocytes. Lines represent median values. N=8 for each group.
