FIG. 5.

Chemotactic responses of PMN to C5a (50 ng/ml). PMN were incubated for 30 min at 37°C in 5% CO₂ alone (NS) or with heat-killed acapsular cryptococci (7698) (E/T ratio, 1:4), GXM alone (250 μg/ml), heat-killed 7698 (E/T ratio, 1:4) pretreated with GXM, or heat-killed encapsulated cryptococci (6995) (E/T ratio, 1:4). The results are the mean and standard error of the mean for three independent experiments with cells from three different healthy subjects. Statistical significance was determined by using ANOVA with Bonferroni's posttest analysis.
