Effect of IL-15 on chemotaxis and fungicidal activity of PMNs from 8 patients with continuous viral suppression after 52 to 130 weeks of HAART.

(A) PMNs were incubated with IL-15 (10 ng/mL) or medium alone for 6 hours and then tested for their ability to migrate in a blind-well chamber toward fMLPB as chemoattractant. (B) PMNs were incubated with medium alone or IL-15 (10 ng/mL) for 6 hours and then assayed for killing activity against Candida by the methylene blue staining technique. Each pair of symbols represents different patients. The gray horizontal zone represents the mean ± SEM of healthy controls.
