Cytokines are a group of small protein molecules with diverse biological activities. They are synthesized and secreted by stimulated immune cells, including monocytes, macrophages, T cells, B cells, NK cells, and certain non-immune cells like endothelial cells, epidermal cells, and fibroblasts. Cytokines play a crucial role in regulating cell growth, differentiation, and function by binding to their respective receptors, thereby modulating immune responses. Prolonged and excessive secretion of inflammatory cytokines can contribute to the development of autoimmune diseases and cancers. Neutralization experiments aim to measure the ability of neutralizing antibodies to interfere with the biological activity of specific cytokines or proteins.
Case: TNF-α neutralization by Adalimumab promotes L929 cell proliferation.
