Stimulation of the cold-sensing receptor TRPM8 activates skin ILC2s.
(A) Percentages and numbers of Lin− ILCs in
the menthol versus control (ethanol)-treated skin of WT mice. (B-E)
Comparison of the percentage and number of CCR10+MHCII+
ILCs (B), CCR10+Clec12a+ ILCs (C),
CCR10−CD81+ (D) and
CCR10−ST2+ (E) ILCs in the menthol versus
control (ethanol)-treated skin of WT mice. (F) Analysis of IL-5
expression by ILCs of the menthol versus control (ethanol)-treated skin of WT
mice. (G) Analysis of CCR10 and CD81 expression on skin ILCs in
WT mice versus TRPM8−/− mice treated with menthol daily
for 2 weeks. (H) Analysis of CCR10 and ST2 expression on ILCs of
the menthol-treated skin of WT versus TRPM8−/− mice.
Both WT and TRPM8−/− mice carry a
CCR10-knockout/EGFP-knockin (CCR10+/EGFP) allele for purpose of
identifying CCR10+ cells with EGFP. One dot is one sample.
*P<0.05, **P<0.01. ***P<0.001, ***P<0.0001, NS: no
significant difference. Statistical significance was determined by unpaired T
test for the panel F, paired T test for panels A-E, G-H.
