At 2 days post-fertilization (dpf),Lyz:dsRed or mpx:GFPlarvae were transferred into DMSO ctrl or FK506 (1 μg/ml) containing 0.5 × E2. At 3 dpf, zebrafishlarvae were microinjected with AFeGFPconidia into the hindbrain and mortality, and fungal burden and neutrophil recruitment were assessed. D TNF-α mRNA levels were measured in whole non-infected or infected larvae 48 h p.i. Immunosuppression led to significant and almost complete inhibition of TNF-α expression during infection.
