Mincle deficiency failed to respond to Malassezia. (A) Malassezia-induced cytokine production. Mincle+/+ and Mincle−/− BMMφ were stimulated with 1, 3, 10 × 106 of M. pachydermatis, 100 μg/ml zymosan or 1 ng/ml LPS for 18 h. *, P < 0.05. (B) Malassezia-induced cytokine transcription. BMMφ was stimulated with 10 × 106 M. pachydermatis or 100 μg/ml zymosan for 4 h, and mRNA expression was determined by real time PCR. Relative mRNA levels were expressed as fold induction. *, P < 0.05. (C) Mincle+/− (WT) and Mincle−/− (KO) mice were injected with 4 × 107 M. pachydermatis i.p. After 18 h, the peritoneal cavity was washed out with 5 ml of saline and cytokine concentration was determined by ELISA. Each symbol represents an individual mouse. Data are representative of two independent experiments. *, P < 0.05. (D) Mincle+/+ or Mincle+/− (WT) and Mincle−/− (KO) mice were injected with 2.5 × 107 M. pachydermatis i.p. At 20 h after injection, peritoneal cells were stained with CD11b and Gr1 and analyzed by flowcytometry. Total number of peritoneal cells (Left) and CD11b+Gr1+ cells (Right) were indicated. Data are representative of two independent experiments. *, P < 0.05.
