大鼠外周血淋巴细胞与绵羊红细胞(SRBC)在含Ca~(++)、Mg~(++)的Hanks液中,37℃温育4h后,进行扫描电镜观察。发现淋巴细胞与SRBC紧密接触,SRBC表面出现孔隙,形态改变。根据过去的实验认为起这种作用的淋巴细胞是NK细胞,NK细胞引起SRBC穿孔和破坏很可能是通过它所释放的某些物质。 Rat peripheral blood lymphocytes and sheep erythrocytes (SRBC) were cultured in Hanks solution containing Ca ~ (++) and Mg ~ (++) at 37 ℃ for 4 h, then observed by scanning electron microscopy. Lymphocytes were found to be in close contact with SRBC, with pores and morphological changes on the SRBC surface. According to past experiments that play a role in this lymphocyte is NK cells, NK cells caused by SRBC perforation and destruction is likely to be some of the substances released by it.
