Peritoneal exudate T lymphocytes from mice immunized with live Listeria monocytogenes were cloned in double-layer soft agar containing heat-killed L. monocytogenes (lower layer) and syngeneic accessory cells (upper layer). Colony-derived T cells were propagated in vitro in the presence of listerial antigen, syngeneic accessory cells, and T cell growth factor. In vitro proliferation, interleukin secretion, and bystander help for B cells of six such T cell lines and several sublines derived from them were found to be antigen dependent and restricted by the H-2IA locus of the major histocompatibility complex. In vivo, these T cell lines conferred delayed-type hypersensitivity to listerial antigen and protection to live L. monocytogenes. It is concluded that different biological functions of acquired antibacterial immunity can be mediated by a single T cell population.
用活的单核细胞增生李斯特菌免疫的小鼠的腹腔渗出液T淋巴细胞,在含有热灭活的单核细胞增生李斯特菌(下层)和同基因辅助细胞(上层)的双层软琼脂中进行克隆。来自菌落的T细胞在李斯特菌抗原、同基因辅助细胞和T细胞生长因子存在的情况下进行体外增殖。发现六个这样的T细胞系及其衍生的几个亚系的体外增殖、白细胞介素分泌以及对B细胞的旁观者辅助作用是抗原依赖性的,并受主要组织相容性复合体的H-2IA基因座限制。在体内,这些T细胞系赋予对李斯特菌抗原的迟发型超敏反应,并对活的单核细胞增生李斯特菌提供保护。得出的结论是,获得性抗菌免疫的不同生物学功能可由单一T细胞群体介导。
