Influence of RNase A on mixed lymphocyte reaction. A, CD4+ Teff cells were isolated from naive human PBMCs and exposed to buffer only or towards polyclonal antiCD3/antiCD28 antibodies; proliferation of resting Teff cells was carried out by a CFSE dilution assay. B, The proliferation of allogeneic stimulated Teff cells was analyzed in MLR (co‐culture of isolated Teff cells with donor PBMCs in a ratio of 1:4) in the absence or presence of RNase A. Data represent the analysis of 2 independent experiments (n=6) and are shown as means±SD. CFSE indicates carboxyfluorescein succinimidyl ester; MLR, mixed lymphocyte reaction; PBMC, peripheral blood mononuclear cells; Teff, effector T cell.
