The MM27.7B1 monoclonal antibody specifically binds to the p28 subunit of mouse Interleukin-27 (IL-27 p28) that is also known as IL-27 alpha (IL-27α) or Interleukin-30 (IL-30). IL-27 p28 is a member of the IL-6/IL-12 family of cytokines. The IL-27 p28 subunit binds to the EBI3 (Epstein-Barr virus induced gene 3) protein to form heterodimeric Interleukin-27. IL-27 p28 is produced by macrophages and dendritic cells stimulated by inflammatory cytokines and ligands for Toll-like receptors (TLR). IL-27 binds to and transduces signal through surface IL-27 receptors (IL-27R) that are expressed by B cells and naive T cells and more highly expressed by NK cells and activated T cells. The IL-27R complex is comprised of gp130 (CD130) and WSX-1 (IL-27R alpha) subunits. IL-27 signals through IL-27R that activate the Jak/STAT signaling pathway resulting in the phosphorylation of Stat1 and Stat3. It acts in a proinflammatory manner to upregulate cellular T-bet transcription factor and surface IL-12R beta2 expression contributing to higher levels of IFN-γ and granzyme B expression. IL-27 exerts anti-inflammatory responses by suppressing the differentiation and proliferation of Th2 and Th17 cells. IL-27 p28 is reportedly produced and secreted independently of EBI3. It may inhibit the actions of IL-17 and other proinflammatory cytokines like IL-6. The MM27/7B1 antibody has been reported to neutralize IL-27 activity in vitro. Routine quality testing of mAb MM27.7B1 is performed via flow cytometry of intracellularly stained IL-27 p28-transfected cells.
