A type of immunotherapy that is being used experimentally for some types of cancer. TNF is a naturally occuring substance produced by blood cells called macrophages and T cells. TNF naturally attacks tumour cells. When it is used as treatment, it is used in much larger quantities. We do not know whether these larger quantities will be more likely to kill cancer cells. Or whether there could be damaging side effects. This type of treatment is still experimental.

a proinflammatory cytokine that is produced by white blood cells (monocytes and macrophages); has an antineoplastic effect but causes inflammation (as in rheumatoid arthritis)

One of the cytokines, or messengers, known to be fundamental to the disease process that underlies psoriasis. It often plays a key role in the onset and the continuation of skin inflammation.
