TNF-alpha is an important cytokine produced by numerous cell types including neutrophils, activated lymphoctyes, macrophages an NK cells.
It plays a critical role in inflammatory responses and in apoptosis (1).
TNF-alpha exists as a membrane-anchored and soluble form, both of which show biological activity.
Response to TNF-alpha is mediated through two receptors, TNF-R1, which is widely expressed, and TNF- R2, which is expressed mainly in immune and endothelial cells (2).
Antagonists to TNF-alpha have been validated as therapeutic targets for rheumatoid arthritis and other immune disorders (3).
The two receptors for TNF-alpha, TNF-R1 (55 ) and TNF-R2 (75kD) can mediate distinct cellular responses (4, 5).
In most cases cytotoxicity elicited by TNF has been reported to act throught TNF-R1 (6,7).
In contrast, TNF-R2 appears to be important in T cell signaling and responses to infection (7,8).
TNF-R2 binds to distinct members of the TRAF family leading to the activation of NF- kappa B (9,10).
Soluble forms of both receptors have also been characterized which can bind TNF-alpha and may play an important role in immune disorders (11,12).
