FBMC proliferate in response to C. neoformans. FBMC (2 × 105/well) were cultured for 7 days with medium alone, C. neoformans (2 × 105/well), SEB (1 μg/ml), or tetanus toxoid (1:10 Lf). This experiment was repeated four times with similar, statistically significant results. ∗, P < 0.05 compared to the value for FBMC alone; NS, not significant compared to FBMC alone.
