1 RESULTS: IVIG inhibited the PHA-induced proliferation of CBMCs as reflected by the decreased expression of CD25 and CD45RO. cbmcs interleukin 2 receptor subunit alpha Homo sapiens
2 But a decreased response in CD25(+) CBMCs (77.29% +/- 0.63%, 51.48% +/- 1.85% and 62.73% +/- 1.24%) and CD4(+)CD45RO(+) CD3(+) T lymphocytes (35.47% +/- 2.55%, 40.14% +/- 1.16% and 36.41% +/- 2.96%) was observed when IVIG was added in IVIG pre-inhibition group, PHA pre-activation group and PHA+IVIG group, and the degree of inhibition of IVIG on cord blood CD3(+) T lymphocytes was much lower than that of CBMCs. cbmcs interleukin 2 receptor subunit alpha Homo sapiens
3 CONCLUSIONS: Cord blood T lymphocytes activation was inhibited by IVIG through the inhibition of CD25(+) CBMCs expression and the prevention of transformation from CD4(+)CD45RA(+) cells into CD4(+)CD45RO(+) cells. cbmcs interleukin 2 receptor subunit alpha Homo sapiens
