Figure 5. Phagocytic events accumulate in older flies.

Figure 5

A) One and five week old flies from the natural variant line 387 were injected with fluorescent E. coli and dissected at indicated times. Phagocytic events were counted for active cells only. Young flies exhibit a near-constant number of engulfed bacteria while older flies accumulate bacteria with time. N= number of flies and (total cells) assayed. B) Time course of bead engulfment. One and five week old flies from the natural variant line 387 were injected with fluorescently labeled plastic beads, which are not broken down by phagocytosis. Flies were dissected and fixed at indicated times. Hemocytes of young and old flies appeared to engulf and accumulate beads at a very similar rate, with no statistically significant difference between the ages. (See text for statistical analyses.)
