AM expression of proinflammatory cytokines TNF-α, IL-6, IL-1β, and chemokine RANTES drastically increased 2-wpi compared to AMs of naïve macaques (p < 0.0001 for all), but dropped significantly with progression to chronic infection. In addition, the low proinflammatory cytokine response in chronic infection was not associated with an increase in IL-10-expressing AMs. To investigate AM activation, BAL cells obtained from naïve and acute and chronically infected macaques at weeks 2, 4, 8, 12, and 20 wpi, were incubated with native gp120 from R5 tropic SIV or LPS for 6 h, and intracellular expression of MIP-1β and IL-6 was assessed (Figures 3A,B) . Decreased Fc receptor expression on innate immune cells is associated with impaired antibody-mediated cellular phagocytic activity in chronically HIV-1 infected individuals ./cache/cord-259131-36udb7uc.txt ./txt/cord-259131-36udb7uc.txt
