Synovial fibroblasts from non-inflamed synovium express numerous ligands for natural killer (NK) cell receptors. Synovial fibroblasts derived from tissue of non-inflamed joints were surface stained for expression of (a) fibroblast-marker CD55 and macrophage-marker CD68, ligands for activating NK cell receptors (b) NKG2D [MHC class I-chain related protein A,B (MIC-A,B) and UL-16 binding protein 1 (ULBP-1; ULBP-2/5/6,3)] and (c) DNAX accessory molecule 1 (DNAM-1; CD155 and CD112), lymphocyte function-associated antigen 1 (LFA-1; CD54) and 2B4/CD244 (CD48); and (d) ligands for inhibitory NK cell receptors. Filled histograms represent isotype-matched control immunoglobulin. Figure shows stainings from two donors.
