腫瘤壞死因子（TNF）舊稱腫瘤壞死因子-α（TNF-α）^[1]以區別腫瘤壞死因子-β，屬腫瘤壞死因子超家族一員，是一種涉及到系統性炎症的細胞因子，同時也是屬於引起急相反應（英語：Acute-phase protein）的眾多細胞因子中的一員。主要由巨噬細胞分泌，不過有一些其它類型的細胞也能生產。

功能

總括而言，腫瘤壞死因子能抑制不同種流感病毒的複製，擁有強大的抗病毒效果^[2]。腫瘤壞死因子的主要作用是調節免疫細胞的功能。作為一種內源性致熱原，它能夠促使發熱，引起細胞凋亡，（通過誘使產生IL1和IL6（英語：Interleukin 6））引發敗血症，引起惡病體質，引發炎症，阻止腫瘤發生和病毒複製（英語：Viral replication）。

腫瘤壞死因子生產的失調被認為與許多人類疾病有關，包括阿茲海默症^[3]、癌症^[4]、重性抑鬱障礙^[5]和腸炎。^[6]雖然仍有爭議，不過當前的研究認為腫瘤壞死因子α的水平與抑鬱和腸炎有關。^[7]基因工程生產的腫瘤壞死因子被用作免疫興奮劑（英語：Immunostimulant）（國際非專利藥品名稱為他索納明）。腫瘤的惡變過程中，腫瘤壞死因子α常異位表達，而其過量表達同副甲狀腺素一道與引發繼發性高鈣血症和癌症有關。

炎症過程中釋放的TNF與H2O2誘導的BCa轉化有關，伴血吸蟲感染的BCa患者血清中TNF水平顯著升高。另外，T3及T4期患者TNF水平高於T1及T2早期患者，提示TNF水平可能有助於BCa的進展^[8]。由於TNF有助於BCa的形成和發展，故而可以作為評估BCa侵襲性和惡性程度的指標^[9]。
