Piezo1 expression is related to the TH9 cell differentiation in allergic airway inflammation and tumors (A) Piezo1 mRNA expression examined by qPCR analyses in T cells activated by various T cell subset-inducing conditions for 5 days (expression in naive T cells was set to 1). (B) Naive T cells were activated by indicated condition for different time course, and Piezo1 mRNA expression was determined by qPCR. Expressions in naive T cells were set to 1. (C) Expression of Piezo1 examined by western blot in T cells activated by the indicated condition for 5 days. (D) Wild-type (WT) mice were sensitized and challenged intranasally with ovalbumin (OVA). mRNA expression of Il9 and Piezo1 in sorted CD4+ T cells isolated from pulmonary dLN cells in WT mice at the indicated time point. (E and F) B16.F10 (E) and EL-4 (F) tumor cells were implanted subcutaneously in WT mice. mRNA expression of Il9 and Piezo1 in sorted CD4+ T cells isolated from tumor in WT mice at the indicated time point.
