Figure Lengend Snippet: Autophagy is triggered and mediates the secretion of IL-1β upon stimulation of wear particles. (A, B) WB and immunofluorescence results of autophagy-related proteins in RAW264.7 cells challenged with different wear particles (scale bar: 20 μm). (C) Quantification of LC3-II level in WB. (D) Quantification of LC3 immunofluorescence intensity. (E) Concentrations of IL-1β and pro-IL-1β in culture supernatants of RAW264.7 cells stimulated with wear particles for 12 h in the absence or presence of 3-methyladenine (3-MA) (5 mM). (F) Immunofluorescence staining on RAW264.7 cells and 3D reconstruction for IL-1β (red), LC3 (green), and DAPI (blue) (scale bar: 5 μm). Yellow spots indicate co-localization. (G) 3D co-localization analysis was conducted using the IMARIS coloc plugin. (H) Co-localization analysis of red channel (IL-1β) and green channel (LC3) conducted by FIJI software. (I) Colocalization line tracing analysis from images in (F). Gray arrows indicate the region of red-green overlap. (J) Pearson's colocalization coefficient for IL-1β and LC3. Sample size: n = 3 per group. All experiments were performed with n = 3 independent biological replicates. (ns indicates P > 0.05, *** indicates P < 0.001, and **** indicates P < 0.0001).
