TNF-a, the prototypical member of the TNF protein superfamily, is a homotrimeric type-II membrane protein (1,2).
Membrane-bound TNF-a is cleaved by the metalloprotease TACE/ADAM17 to generate a soluble homotrimer (2).
Both membrane and soluble forms of TNF-a are biologically active.
TNF-a is produced by a variety of immune cells including T cells, B cells, NK cells, and macrophages (1).
Cellular response to TNF-a is mediated through interaction with receptors TNF-R1 and TNF-R2 and results in activation of pathways that favor both cell survival and apoptosis depending on the cell type and biological context.
Activation of kinase pathways (including JNK, Erk (p44/42), p38 MAPK, and NF-kB) promotes the survival of cells, while TNF-a-mediated activation of caspase-8 leads to programmed cell death (1,2).
TNF-a plays a key regulatory role in inflammation and host defense against bacterial infection, notably Mycobacterium tuberculosis (3).
The role of TNF-a in autoimmunity is underscored by blocking TNF-a action to treat rheumatoid arthritis and Crohn’s disease (1,2,4).
