Monocytic myeloid-derived suppressor cell (M-MDSC) frequencies. (A) Polymorphonuclear myeloid-derived suppressor cell (PMN-MDSC) levels were significantly lower than M-MDSCs in the New Era (NE) population (p = 0.008). (B) M-MDSCs in the NE group were similar to the 3ART patients. (C) Comparable frequencies in the subgroups primary HIV infection (PHI) and chronic HIV infection (CHI) (p = 0.2). (D) The M-MDSC levels in the patients with antiretroviral therapy (w ART) and w/o ART were significantly increased compared with the HIV-uninfected controls (HC) group (p < 0.002) [HC: n = 10; 3ART: n = 10; NE: n = 19 (PHI: n = 8; CHI: n = 11); progressors (PR): n = 10; CO: n = 10].
