A: IHC with anti-CD68 antibody in tissues containing titanium particles (highlighted), only inflammatory cells around the particles are positive. B: IHC with anti-CD68 antibody in tissues without titanium particles. Arrow shows inflammatory cells with intense CD68 positivity. C: IHC with anti-TGF-β antibody in tissues containing titanium particles (highlighted), only inflammatory cells around the particles are positive. D: IHC with anti-CD68 antibody in tissues without titanium particles and minimal inflammatory cells positivity. E: IHC with anti-RANKL antibody in tissues containing titanium particles (highlighted), only inflammatory cells around the particles are positive. F: IHC with anti-RANKL antibody in tissues without titanium particles, certain inflammatory cells, morphologically identified as macrophages show intense positivity (arrow). G: IHC with anti-IL33 antibody in tissues containing titanium particles (highlighted), most inflammatory cells around the particles are positive. H: IHC with anti-IL33 antibody in tissues without Ti particles, some inflammatory cells, show intense positivity (arrow). Images are at 200× magnification.
