Figure Lengend Snippet: CIRBP promotes collagen production and proliferation via TLR2/4-dependent IL-6 signaling. ( A ) IL-6 concentrations in the culture supernatants of primary lung fibroblasts treated with rmCIRBP, with or without C23, TLR4-I, or TLR2-I, measured by ELISA. ( B ) Soluble collagen levels in the supernatants following treatment with rmCIRBP ± anti-IL-6 antibody.

( E ) Fibroblast proliferation measured using the WST assay following cotreatment with rmCIRBP and TLR4-I or TLR2-I. ( F ) Schematic representation of the proposed mechanism: CIRBP, which is highly expressed in fibrotic lungs, stimulates IL-6 production via TLR2/4, promoting collagen secretion and fibroblast proliferation in an autocrine manner and contributing to the progression of tissue fibrosis. Data are presented as mean ± SEM. *P < 0.05 using one-way ANOVA and Tukey’s multiple comparison test.
