Expression of natural killer (NK) cell receptors on paired rheumatoid arthritis synovial fluid mononuclear cell (RA SFMC) and peripheral blood mononuclear cell (PBMC) samples. Frozen samples of paired SFMC and PBMC from n = 4 to n = 8 RA donors were stained for expression of various NK cell receptors as indicated. Dot plots in (a) are representative examples of NK receptor expression and (b) shows % NK cells positive for a given receptor, relative to isotype-matched control immunoglobulin. NK cells were gated as viable, single, CD3− CD14− CD56+ cells.
