IL-13Rα1 (A) and IL-13Rα2 (B) proteins were reduced by their specific shRNA compared to each scrambled shRNA-treated control. C-F, Effect of IL-13Rα1/2 knockdown on IL-13-induced chemerin (C), TNFα (D), CCL17 (E), CCL22 (F) release from mDRGs (2-way ANOVA followed by Bonferroni’s post hoc analysis). Pam3CSK4 pre-treatment increased IL-13 induced release. Data are presented as mean ± SEM; n ≥3. For A and B, Student 2-tailed t-test: ***P < 0.001.

Article Snippet: For cytokine array, cells incubated with or without Pam3CSK4 (1 μg/ ml) or vehicle for 6 h at 37 ◦C were washed and stimulated by IL-13 (100 ng/ml, Abcam) at 37 ◦C for 24 h. Cell-culture supernatants were analysed using proteome profiler mouse XL cytokine array kit (R&D Systems) before being analysed with ImageJ software.

Figure Lengend Snippet: Fig. 8 A schematic diagram of mechanism of exosomal HSPC111 facilitates CRLM via reprogramming lipid metabolism in CAFs. Exosomal HSPC111 derived from CRC cells phosphorylates ACLY in CAFs, leading to the increased levels of acetyl-CoA and histone acetylation to secrete CXCL5, and resulting in CRC cells colonized in liver via the CXCL5-CXCR2 axis.
