ABSTRACT
Objective To observe secretive ability of three C-C chemokines, macrophage inflammatory protein-1?(MIP-1?),MIP-1? and regulated-upon activation.normal T-cell expressed and secretory factor(RANTES)by lympocytes and moncytes of cord blood from chinese necnates and peripheral blood from chinese adults.Method Using Ficoll density-gradient centrifugation and gelatin-coated flask,the Iympocytes and monocytes were isolated from cord blood samples of seventeen Chinese neonates and peripheral blood samples of twenty Chinese adults.Purified lymphocytes and monocytes were incubated with PMA and LPS,respectively.Supernants were tested by ELISA for concentrations of MIP-1?,MIP-1? and RANTES.Results Concentrations of MIP-1?, MIP-1? and RANTES in cord blood lymphocyte and monocyte were (3920?730)pg/ml, (4910?590)pg/ml,(1470?410)pg/ml,(3240?980)pg/ml,(1960?1300)pg/ml and (240?120)pg/ml,respectively,and in adults peripheral blood were (6560?840)pg/ml,(5810?1150)pg/ml,(2250?570)pg/ml,(3010?1350) pg/ml,(2280?870)pg/ml,(690?430)pg/ml,respectively.Cord blood lymphocyte and monocyte showed diminished ability to secrete RANTES than adult peripheral blood.Conclusions The diminished RANTES secretion of cord blood lymphocyte and monocyte may be releted to the pathogenesis of Chinese neonatal HIV infection,and indicated some immunotherapies are feasible for preventing neonate from HIV mother-to-child transmission.
