     m6A levels in EVs regulate inflammatory responses via TLR8 in macrophages. Differentiated THP‐1 cells (dTHP‐1) were pretreated with or without CU‐CPT‐9a (HY-112667; 48 h) and CU‐CPT‐4a (HY-108473; 48 h). Whole‐cell lysates obtained from dTHP‐1 cells were subjected to Western blot analysis using an anti‐phospho p65 antibody, anti‐p65 antibody and anti‐β‐actin antibody. Representative images from three independent experiments are shown.

     TLR3 antagonist CU CPT4a inhibited NTG-induced mechanical allodynia. Repeated treatment with CU CPT4a (5 mg/kg, i.p.) or vehicle (equal volumes of DMSO) every other day before NTG injections for 9 days. Repeated treatment with CU CPT4a inhibited basal hind paw mechanical and periorbital mechanical allodynia.

     TLR3 antagonist CU CPT4a inhibited NTG-induced mechanical allodynia. Repeated treatment with CU CPT4a (5 mg/kg, i.p.) or vehicle (equal volumes of DMSO) every other day before NTG injections for 9 days. Post-treatment responses, including hind paw mechanical and periorbital mechanical allodynia, were estimated 2 h after NTG administration.

     Immunofluorescence images of MMP21 in the absence or presence of RIG012 or CU-CPT 4a. β-cat ΔN/RasV12 cells were mixed with β-cat ΔN cells in the presence of BFA, and were treated with DMSO, 2.5 μM RIG012 or 50 μM CU-CPT 4a. Cells were stained with Hoechst 33342 (blue) and anti-MMP21 antibody (white).
