Tnf b cell
Tumor necrosis factor (TNF, cachexin, or cachectin; formerly known as tumor necrosis factor alpha or TNF-α ) is an adipokine and a cytokine. TNF is a member of the TNF superfamily, which consists of various transmembrane proteins with a homologous TNF domain. As an adipokine, TNF promotes insulin resistance, and is associated with obesity WebbOnly memory B cells (either IgM or switched), but not naïve B cells, make appreciable levels of TNF-α and more in elderly as compared to young individuals. Finally, an anti-TNF-α …
