Macrophages in AL periprosthetic tissues do not express TH or ADRB2. The expression of TH, ADRA1, ADRA2A and ADRB2 (a) and the expression of NPY and Y1R (b) by macrophages (CD68+) was evaluated in periprosthetic tissues from AL patients and in synovial tissues from OA patients through double immunohistochemistry staining. Macrophages expressing TH, ADRA1, ADRA2A, ADRB2 or NPY are highlighted with triangle head white arrows. Simple head white arrows indicate macrophages and white arrowheads highlight TH, ADRA1, ADRB2, NPY and Y1R staining in cells other than macrophages (positive control). Scale bar = 20 μm.
