Abstract

Residual immune activation was studied in 51 HIV-infected individuals, 16 with viral load between 1 and 20 copies/ml and 35 with viral load less than 1 copy/ml, and compared with results in 20 healthy blood donors. Higher T-cell activation and IP-10/CXCL10, MIG/CXCL9 and sCD14 plasma levels persisted in both HIV+ groups. The proportion of activated HLA-DR+ CD4 T cells was inversely correlated with the CD4 nadir and the current CD4 cell counts.
