IL15 and fungal infectious disease: Of the proteins tested, eight in groups F24 and F48 (G-CSF, GM-CSF, M-CSF, IL-3, IL-15, IL-1 β, IL-6, IL-19) showed a significant increase in fluorescence intensity on the fluorescein isothiocyanate (FITC) channel compared to the control (Figure 1); this indicated an increase in their levels in hemocytes after fungal infection.
