IL-15 dose response.

Dose-response of IL-15 on chemotaxis (A) and fungicidal activity (B) of PMNs from untreated HIV⁺ patients (gray columns) and healthy controls (black columns). PMNs were incubated with medium alone or with increased concentrations of IL-15 (10 to 1000 ng/mL) for 6 hours. Results represent the mean ± SEM of values from 3 experiments. Asterisks indicate a significant increase in PMN chemotaxis and fungicidal activity (P < .05).
