Figure Lengend Snippet: (A) Representative Giemsa-stained images of multinucleated FBGCs in WT BMDMs left untreated or stimulated with IL-4 plus GMCSF (25 ng/ml, 96 h), in the presence or absence of the TRPV1 antagonist AMG. (B-D) Quantitative analysis of FBGC formation from (A): (B) number of FBGCs per high-power field, (C) percentage of fused BMDMs, and (D) average FBGC size. Data represent n = 3 biological replicates with 5 images per group; scale bar, 100 μm; Student’s t-test, ***p < 0.001, ****p < 0.0001. (E) Representative immunofluorescence images of WT BMDMs transfected with scramble or TRPV1-targeting siRNA, stained for TRPV1 (red) using anti-TRPV1 IgG (original magnification, 60x; scale bar, 2 μm). (F) Quantification of TRPV1 fluorescence intensity (n = 10 cells per condition; Student’s t-test, ***p < 0.001). (G) Immunoblot showing TRPV1 expression in WT BMDMs 48 h after transfection with scramble or TRPV1 siRNA. (H-J) Quantification of FBGC formation following TRPV1 knockdown: (H) number of FBGCs per high-power field, (I) percentage of fused BMDMs, and (J) average FBGC size. Data represent n = 3 biological replicates with 5 images per group; Student’s t-test, ***p < 0.001.
