能抑制不同种流感病毒的复制，拥有强大的抗病毒效果。肿瘤坏死因子α的主要作用是调节免疫细胞的功能。作为一种内源性致热原，它能够促使发热，引起细胞凋亡，（通过诱使产生IL1和IL6（英语：Interleukin 6））引发败血症，引起恶病体质，引发炎症，阻止肿瘤发生和病毒复制（英语：Viral replication）。肿瘤坏死因子α生产的失调被认为与许多人类疾病有关，包括阿兹海默氏症、癌症、重性抑郁障碍和肠炎。虽然仍有争议，不过当前的研究认为肿瘤坏死因子α的水平与抑郁和肠炎有关。基因工程生产的肿瘤坏死因子α被用作免疫兴奋剂（英语：Immunostimulant）（国际非专利药品名称为他索纳明）。 肿瘤的恶变过程中，肿瘤坏死因子α常异位表达，而其过量表达同副甲状腺素一道与引发继发性高钙血症和癌症有关。炎症过程中释放的TNF-α与H2O2诱导的BCa转化有关，伴血吸虫感染的BCa患者血清中TNF-α水平显著升高。另外，T3及T4期患者TNF-α水平高于T1及T2早期患者，提示TNF-α水平可能有助于BCa的进展。由于TNF-α有助于BCa的形成和发展，故而可以作为评估BCa侵袭性和恶性程度的指标。医学导航：遗传代谢缺陷代谢、k,c/g/r/p/y/i,f/h/s/l/o/e,a/u,n,mk,cgrp/y/i,f/h/s/l/o/e,au,n,m,人名体征药物(A16/C10)、中间产物(k,c/g/r/p/y/i,f/h/s/o/e,a/u,n,m)
