天然LFA-3对于猪血清溶血作用和猪PBMC Et花环的影响

Natural LFA-3 on Hocemolysis of Normal Pig Serum and the Et Rosetle Forming of Pig PBMC

根据解离、吸收猪血清能够阻止正常猪血清对SRBC的破坏作用和猪PBMCE_1花环的形成,推断正常猪血清中存在天然的LFA—3,并从天然LFA—3与游离CD_2和膜CD_2的可能关系中提出了T淋巴细胞激活中游离CD_2调控途径的设想。

Based on the fact that the re-dissociation and SRBC aborbed pig serum can prevent the destruction of normal pig serum on SRBC and the Et rosette-forming of pig PBMC, we deduced that the nermal pig serum contains natural LFA-3, and further, we present a hypothesis of free-form CD2, regulating mechanism in the process of activating of T lymphocyte in accordance with the likely relationships between the natural LFA-3 with Free-form CD2 of cell membrane.
