To investigate the effect of treatment with a pan anti gamma/delta antibody , lymphocytes were incubated for 3 hr with the antibody , and then interleukin ( IL ) -10 , IL-12 and progesterone -induced blocking factor ( PIBF ) expression ( by immuno-cytochemistry ) as well as natural killer ( NK ) cell activity were determined .
