C10 stimulation augments the phagocytic capacity of peritoneal macrophages. Peritoneal macrophages were pretreated with C10 (500 ng/ml) for 1 h prior to the addition of E. coli (10⁶ cells). After a 1-h exposure to the bacterial challenge, the experiment was terminated and the cells were stained. Intracellular bacteria were counted in a sample population of 200 cells per well. Graphed values represent the mean number of E. coli per cell. Statistics were analyzed using a two-tailed t test. Three separate experiments were performed, and the data were pooled. ∗, P < 0.05.
