Human tumor-infiltrating lymphocytes (TILs) derived from pleural or ascitic fluid were incubated with recombinant interleukin 2 and transfected with human tumor necrosis factor (TNF) alpha gene by the lipofection procedure. The resulting TILs secreted significant amounts of TNF in the culture supernatant and exhibited cytotoxicity against established cell lines, such as K562 and Daudi, and autologous tumor cells. The TNF gene-transfected TILs exhibited an augmented killing of autologous tumor cells.
将源自胸水或腹水的人肿瘤浸润淋巴细胞(TILs)与重组白细胞介素2一起孵育,并通过脂质转染法用人类肿瘤坏死因子(TNF)α基因进行转染。所得的TILs在培养上清液中分泌大量TNF,并对诸如K562和Daudi等已建立的细胞系以及自体肿瘤细胞表现出细胞毒性。转染了TNF基因的TILs对自体肿瘤细胞的杀伤作用增强。
