[[http://www.uniprot.org/uniprot/TNFA_HUMAN TNFA_HUMAN]] Genetic variations in TNF are a cause of susceptibility psoriatic arthritis (PSORAS) [MIM:[http://omim.org/entry/607507 607507]]. PSORAS is an inflammatory, seronegative arthritis associated with psoriasis. It is a heterogeneous disorder ranging from a mild, non-destructive disease to a severe, progressive, erosive arthropathy. Five types of psoriatic arthritis have been defined: asymmetrical oligoarthritis characterized by primary involvement of the small joints of the fingers or toes; asymmetrical arthritis which involves the joints of the extremities; symmetrical polyarthritis characterized by a rheumatoidlike pattern that can involve hands, wrists, ankles, and feet; arthritis mutilans, which is a rare but deforming and destructive condition; arthritis of the sacroiliac joints and spine (psoriatic spondylitis). | |||
==Function== | |||
[[http://www.uniprot.org/uniprot/TNFA_HUMAN TNFA_HUMAN]] Cytokine that binds to TNFRSF1A/TNFR1 and TNFRSF1B/TNFBR. It is mainly secreted by macrophages and can induce cell death of certain tumor cell lines. It is potent pyrogen causing fever by direct action or by stimulation of interleukin-1 secretion and is implicated in the induction of cachexia, Under certain conditions it can stimulate cell proliferation and induce cell differentiation.<ref>PMID:16829952</ref> The TNF intracellular domain (ICD) form induces IL12 production in dendritic cells.<ref>PMID:16829952</ref> | |||
