ABSTRACT
Objective To observe the variations of the functional states of T helper cells(Th) in peripheral blood of children with mycoplasma pneumoniae pneumonia(MPP) in acute phase,and to explore their roles in the pathogenesis of MPP.Methods Peripheral blood mononuclear cells(PBMC) of 40 MPP children were stimulated with PMA and ionomycin and cultured in vitro for 48 hours.The levels of IL-4,IFN-?,and TGF-?1 in the supernatants of PBMC were detected by ELISA.Results The levels of IFN-? and the ratio of IFN-?/IL-4 of MPP children in acute phase were significantly lower than those of the controls(P0.05).Conclusions The function of Th2 relatively prevails over Th1 in MPP children.The protective or regulative function of Th3 in vivo increases,but the protective regulation of TGF-?1 is insufficient,so the imbalance of Th1/Th2 can not be corrected.The variation of the functional states of T helper cells in acute phase has no relationship with or without the extrapulmonary damage.
