Figure 4From: Changing survival, memory cell compartment, and T-helper balance of lymphocytes between severe and mild asthma(A) The mean OD value ± 2 standard errors of in vitro PBL synthesis of IFN-γ increased significantly with asthma severity. (B) The mean OD value ± 2 standard errors of in vitro PBL synthesis of IL-4 was significantly highest in mild asthmatics than severe asthmatics and HV groups. (C) The mean ratio ± 2 standard errors of IL-4/IFN-γ was remarkably lower in severe asthmatics than mild asthmatics and HV groups.Back to article page
