BMDMs were stimulated with C.albicans for 24h and the supernatant was isolated and added to primary ILC3 cells. (1) Supernatant from BMDMs without stimulation. (2) Supernatant from BMDMs with stimulation of C.albicans. (3) Supernatant from BMDMs with stimulation of C.albicans and IL-7 antibody. Productions of IL-22 by ILC3 cells were detected by ELISA. mRNA expressions of Il-22 in ILC3 cells were detected by qPCR.
