Primary HIV-1 infection was associated with differential T-cell and NK-cell activation.

Abstract

<p>T-cells (A) and NK cells (B) were activated following HIV infection. The proportion of activated T-cells and NK cells was significantly correlated before (C), but not following HIV-1 infection (D). In contrast, during primary infection, both T-cell (E) and NK-cell (F) activation were positively correlated with HIV viral load (log₁₀ copies/ml) but not CD4+ T-cell counts (G and H respectively).</p
