TRPV1/TRPA1 Control TSLP in Nasal Epithelial Cells
2026-09-24
The study links TRPV1 and TRPA1 activation in nasal epithelial cells to calcium-dependent NFAT signaling and increased TSLP production. Its combination of channel perturbation, calcium chelation, gene-silencing, and NFAT localization helps distinguish the TSLP response from accompanying changes in IL-25 and IL-33, while leaving important questions about pathway specificity and in vivo relevance open.
