Expression of HIV-1 does not affect phagocytosis of E-C3bi. Phagocytosis assays were performed as described in Materials and Methods. The mean phagocytic indices of untransfected U937 control cells for E-IgG and E-C3bi were 237 ± 21 and 176 ± 15, respectively. Data represent the mean ± standard error of mean (SEM) (n = 3).
