Figure Lengend Snippet: LA released from T-gel degradation induces macrophage M2 polarization and promotes fibroblast activation and collagen production. (A) Flow cytometry analysis of the association between T-gel degradation products and macrophage M2 polarization ( n = 3, data represent mean ± s.d.). ∗∗∗∗P < 0.0001. (B) RNA-seq analysis of M2 macrophage marker expression in tissues one week after ID and SC injection of T-gel. (C–D) Immunofluorescence analysis of CD206 (C) and FAPα (D) expression in tissues ( n = 3, data represent mean ± s.d.). ∗∗P < 0.01. (E) Schematic diagram of the co-culture system showing RAW264.7 macrophages pretreated with T-gel extract medium that were subsequently co-cultured with L929 fibroblasts. (F–G) Collagen expression in L929 cells from the co-culture system assessed by Western blot (F) and ELISA (G). “C” represents RAW264.7 pretreated with blank medium; “T” represents RAW264.7 pretreated with T-gel extract medium. n = 3, data represent mean ± s.d. ∗P < 0.05 and ∗∗P < 0.01. (H) ELISA analysis of TGFβ expression in RAW264.7 cells treated with T-gel extract medium ( n = 3, data represent mean ± s.d.). ∗∗P < 0.01. (I) Schematic representation of LA, released during T-gel degradation, programming macrophages toward an M2 phenotype and subsequently promoting fibroblast activation and collagen secretion.

Figure Lengend Snippet: Effects of CCPI on the expression of iNOS and CD206 proteins. (A) Representative Western blot bands showed the expression of iNOS and CD206 after CCPI treatment. (B,C) Quantitative analysis of the iNOS/GAPDH and CD206/GAPDH ratios in the CCPI-treated groups, respectively. Data are presented as mean ± SD ( n = 3). ### p < 0.001 vs. Control group; *** p < 0.001 and ** p < 0.01 vs. AD model group.

Figure Lengend Snippet: Comparison of the effects of CCPI and LA on IL-6 secretion, STAT3 phosphorylation, and the expression of markers associated with pro-inflammation (iNOS) and anti-inflammation/repair (CD206) in AD model cells. (A) IL-6 levels in the AD model cells were measured by ELISA. (B) Western blot showed the expression of iNOS, CD206, STAT3 phosphorylation, and STAT3 after CCPI and LA treatment. (C–E) Quantitative analysis of the iNOS/GAPDH, CD206/GAPDH, and STAT3 phosphorylation/STAT3 ratios in the CCPI and LA-treated groups, respectively. Data are presented as mean ± SD ( n = 3). ### p < 0.001 vs. control group; *** p < 0.001, ** p < 0.01 and * p < 0.05 vs. AD model group; ns p > 0.05 compared with the CCPI group; compared with the LA group, ns p > 0.05.
