عامل نخر الورم ألفا
بروتين في الإنسان العاقل
(بالتحويل من عامل نخر الورم)
عامل نخر الورم ألفا (بالإنجليزية: Tumor necrosis factor alpha) ومختصره (TNFα) ويسمى أيضا كاككتين (بالإنجليزية: cachectin) أو كاككسين (بالإنجليزية: cachexin) هو بروتين إشارة خلوية (سيتوكين) يشارك في عملية الالتهاب في جسم الإنسان.[29][30][31]
عامل نخر الورم ألفا
حاليا بحذف كلمة ألفا من تسمية عامل نخر الورم ألفا والاكتفاء بتسميته عامل نخر الورم لأن لمفوتوكسين ألفا لم يعد يسمى عامل نخر الورم بيتا.

In human cells, contrary to results previously obtained in a rodent model, TNF seems not to be glycosylated and, thus, trafficking is carbohydrate independent. In an effort to localize the amino acid motif responsible for granule targeting, we constructed additional fusion proteins and analyzed their trafficking, concluding that granule-targeting sequences are localized in the mature chain of TNF and that the cytoplasmic tail is expendable for endocytotic sorting of this cytokine, thus excluding direct interactions with intracellular adaptor proteins
