Abstract

Mononuclear cells from normal rabbit blood were cytotoxic to a number of cell lines in vitro. The cytotoxic cells were contained in the monocyte-enriched fraction adherent to plastic. Supernatants of the monocyte-enriched fraction had the same cytotoxic specificity as the parent cells. The cytotoxic factor precipitated in 50% saturated ammonium sulphate solution and on gel filtration was heterogeneous with a mol.-wt. range of 30--50,000 u. On the basis of specificity and molecular characteristics, this cytotoxic factor closely resembles rabbit tumour-necrosis factor (TNF) suggesting that TNF or a closely related factor is a normal product of mononuclear phagocytes.

摘要

正常兔血中的单核细胞在体外对多种细胞系具有细胞毒性。细胞毒性细胞存在于附着于塑料的富含单核细胞的部分中。富含单核细胞部分的上清液与亲代细胞具有相同的细胞毒性特异性。细胞毒性因子在50%饱和硫酸铵溶液中沉淀,经凝胶过滤后分子量不均一,范围为30 - 50,000道尔顿。基于特异性和分子特征,这种细胞毒性因子与兔肿瘤坏死因子(TNF)非常相似,表明TNF或密切相关的因子是单核吞噬细胞的正常产物。
