Sword Assay for Human TNF-alpha

TNFα is a pleiotropic inflammatory cytokine produced predominantly by macrophages, and serves a variety of functions; possessing both growth stimulating and growth inhibitory processes, as well as having self-regulatory properties.1 TNFα interacts with receptors TNFR1 and TNFR2, and these are expressed differently on cells and tissues resulting in signaling cascades.

This can lead to a range of responses including: cell death, survival, differentiation, proliferation, and migration.2 TNFα cannot usually be detected in healthy individuals; however, elevated serum and tissue levels are found in inflammatory and infectious conditions, and serum levels correlate to the severity of infections.2 Lack of regulation of TNFα production has been implicated in a variety diseases such as Alzheimer’s disease, cancer, and Crohn’s disease.2-4
