α肿瘤细胞系坏死因子（TNF－α）起初是作为一种诱发某些肿瘤和肿瘤坏死的蛋白而确认的。可通过激活巨噬细胞释放出来。作者研究了TNF－α受体的表达，以了解TNF－α在肺癌细胞和正常肺组织中的生物活性。材料和方法选择因肺癌手术的患者15例，包括鳞癌8例，腺癌5例，小细胞肺 Alpha tumor cell necrosis factor (TNF-α) was initially identified as a protein that induces necrosis of certain tumors and tumors. It can be released by activating macrophages. The authors studied the expression of TNF-α receptors to understand the biological activity of TNF-α in lung cancer cells and normal lung tissues. Materials and Methods 15 patients with lung cancer surgery were selected, including 8 squamous cell carcinomas, 5 adenocarcinomas, and small cell lungs.
