Figure 4
T cells express ADRA1 both in AL periprosthetic tissues and OA synovial membrane. The expression of TH, ADRA1, ADRA2A and ADRB2 (a), and the expression of NPY and Y1R (b) in T cells (CD3+) was evaluated in periprosthetic tissues from AL patients and in synovial tissues from OA patients through a double immunohistochemistry staining. T cells expressing TH or ADRA1 are highlighted with triangle head white arrows. Simple head white arrows indicate T cells and white arrowheads highlight ADRA1, ADRA2A, ADRB2, NPY and Y1R staining in cells other than T cells (positive control). Scale bar = 20 μm.
