How They Work. TNF inhibitors are antibodies made in a lab from human or animal tissue. (Your body makes antibodies to fight off infections.) Once they're put into your blood, they cause a reaction in your immune system that blocks inflammation.
Why is TNF important?
Tumor necrosis factor (TNF) is a multifunctional cytokine that plays important roles in diverse cellular events such as cell survival, proliferation, differentiation, and death. As a pro-inflammatory cytokine, TNF is secreted by inflammatory cells, which may be involved in inflammation-associated carcinogenesis.
What does TNF do in inflammation?
Being one of the most important pro-inflammatory cytokines, TNF-α participates in vasodilatation and edema formation, and leukocyte adhesion to epithelium through expression of adhesion molecules; it regulates blood coagulation, contributes to oxidative stress in sites of inflammation, and indirectly induces fever.

These drugs bind to tumor necrosis factor-alpha, rendering it inactive. This interferes with inflammatory activity and suppresses your immune system.
What is the TNF in the body?
Tumor necrosis factor (TNF) is a substance produced by cells in your immune system that has many effects in promoting the inflammatory process. It is produced chiefly by macrophages, a type of white blood cell, but can be produced by other cells as well. TNF is a major cause of the excess inflammation that drives rheumatoid arthritis.
What is the TNF response?
Tumor Necrosis Factor in the Immune Response. TNF is a natural part of the body's immune response to tumor cells, bacteria, and viruses. It plays a part both in acute reactions and systemic inflammation. Cells release it when they detect a specific substance (an antigen) to which they have become sensitized.

TNF and TNF Receptors
- Tumor necrosis factor-awas originally named for its ability to trigger necrosis of transplanted tumor cells in mice. The purification and cloning of a molecule called “cachectin”, which causes wasting in chronic diseases, was subsequently found to be identical to TNF-a. TNF is produced …
Development of TNF Inhibitors
- The two strategies for inhibiting TNF that have been most extensively studied to date consist of monoclonal anti-TNF antibodies and soluble TNF receptors (sTNF-R) (Table II). Both constructs will theoretically bind to circulating TNF-a, thus limiting its ability to engage cell membrane-bound TNF receptors and activate inflammatory pathways. Soluble TNF-R, but not anti-TNF antibodies, …
Animal Studies
- Several lines of evidence exist in animal models that support the importance of TNF-ain the pathogenesis of human RA. Although no animal model of inflammatory arthritis is thought to completely mimic human RA, studies in animals have provided important information on inflammatory mediators and their potential as therapeutic targets in human disease. Most comp…
Human Clinical Trials
- Because the safety of the TNF inhibitors in humans was unknown, early trials in RA targeted patients with severe, longstanding disease that had failed to respond adequately to conventional treatments such as methotrexate, gold salts, immunosuppressives and others. More recently, as the safety of these agents unfolded, patients with juvenile RA and adults with early RA have bee…
Potential Side Effects and Precautions
- TNF plays an important role in host defenses, particularly in the killing of intracellular microorganisms such as Listeria and mycobacteria, and in inducing apoptosis of some tumor cells. Consequently, there has been some concern that long-term inhibition of TNF could lead to an increased incidence of infection and of malignancy. In addition, as these agents are genetical…
Conclusion
- In vitro studies suggested that TNF is a critical and proximal mediator of the inflammatory pathway in the rheumatoid joint. Proof-of-concept for this hypothesis has now been provided by animal studies and clinical trials. Not only does TNF inhibition dramatically reduce markers of inflammation but it also slows or halts structural damage, and these effects appear to be as pot…
