Monocyte phenotype distribution in peripheral blood and expression of costimulatory molecules (CD86 and CD40) nonclassical monocytes. (A) Monocyte phenotypes among the antiretroviral therapy (ART)-treated human immunodeficiency virus (HIV)⁺ individuals with CD4 count of >500 cell/µL and supressed viral load in comparison with the age-matched, healthy, HIV-negative population from the same community. (B) CD86 and CD40 expression on nonclassical monocytes of ART-treated HIV-infected and HIV-negative individuals after 1 ng/mL lipopolysaccharide stimulation. The Mann-Whitney U test was used to compare the monocyte proportions between HIV-infected and healthy subjects.
