Fig. 6. Correlation of TRPM8 mRNA expression with IL-25 (A), TSLP (B), and IL-33 (C) expression in the sputum of asthmatics. The relationships between TRPM8 and cytokines were assessed by using Spearman rank correlation.

TRPM8, transient receptor potential melastatin family member 8; IL, interleukin; TSLP, thymic stromal lymphopoietin; GAPDH, glyceraldehyde 3-phosphate dehydrogenase.
