Persistent depletion of CCR5-expressing NLHP Th lymphocytes in PHI patients undergoing HAART treatment.

The median (IQR) CD4⁺ T cell count (A), the median (IQR) percentage of CCR5-expressing NLHP Th cells (B), the median (IQR) CCR5-expressing NLHP Th cell count (C), and the median (IQR) α₄β₇⁺ Th cell count (D) were followed in 12 PHI patients treated with HAART. Shaded areas represent the 75% to 25% IQR values for healthy controls. The solid symbol in the shaded area represents median for the controls. *P < .05; **P < .005 by 2-tailed Student t test.
