Abstract

Recent evidence suggests that synovial macrophage activation may be involved in cartilage destruction and pain in osteoarthritis (OA). The macrophage-inducible C-type lectin (Mincle) Clec4e is expressed in macrophages and is regulated in inflammatory conditions. Given that the regulation of Mincle in synovial macrophages has not been elucidated, we investigated the expression and regulation of Mincle in human synovial tissue (ST) harvested from patients with radiographic knee OA during total knee arthroplasty. Immunohistochemical and flow cytometric analyses were used to identify cells with Mincle expression in resected tissues. CD14-positive (CD14
