Evaluation of nonspecific ADCC activity mediated by invariant NKT cells. a The representative flow plots indicated CD16, CD161 and CD69 expression on human invariant NKT cells (iNKT, CD3+ 6B11+) and CD56+ T cellsrespectively. b Comparison of CD16, CD161 and CD69 expression on iNKT and CD56+ T cells from ten healthy donors. c The representative flow plots indicated IFNγ production by iNKT and CD56+ T cells stimulated by Ab-bound P815 cells. d The frequencies of IFNγ+ iNKT and IFNγ+ CD56+ T cells from ten healthy donors in response to P815 cells alone or Ab-coated P815 cells. All P values were two-tailed and considered significant when less than 0.05
