Effects of rIL-10 and rTGF-β on granzyme-B release by NK cells
PBMCs were co-cultured with rIL-10 and/or rTGF-β for 5 h, and then stimulated with PMA and ionomycin for 6 h. The inhibition of granzyme-B release by NK cells using different concentrations of rIL-10 (a) or rTGF-β (b) was determined. The effect of treatment with both rIL-10 and rTGF-β on granzyme-B release by NK cells was synergistic (c)
