IL-6 Protein, Cynomolgus (HEK293, His)

IL-6 is a cytokine with multiple functions in immunity, tissue regeneration, and metabolism, coordinating complex signaling. Binding to IL6R initiates the IL6 signaling pathway through a complex with the signaling subunit IL6ST/gp130. IL-6 Protein, Cynomolgus (HEK293, His) is the recombinant cynomolgus-derived IL-6 protein, expressed by HEK293 , with C-His labeled tag. The total length of IL-6 Protein, Cynomolgus (HEK293, His) is 185 a.a., with molecular weight of 25-30 kDa.

IL-6, a cytokine boasting a diverse array of biological functions spanning immunity, tissue regeneration, and metabolism, engages in a sophisticated signaling orchestration. Upon binding to IL6R, the resulting complex orchestrates the intracellular IL6-signaling pathway through its association with the signaling subunit IL6ST/gp130. Interactions with membrane-bound IL6R and IL6ST prompt 'classic signaling,' whereas binding of IL6 to soluble IL6R and IL6ST elicits 'trans-signaling.' Furthermore, 'cluster signaling' unfolds as membrane-bound IL6:IL6R complexes on transmitter cells activate IL6ST receptors on adjacent receiver cells. IL-6 serves as a potent inducer of the acute phase response, rapidly contributing to host defense during infection and tissue injury, yet its overproduction is implicated in disease pathology. In the innate immune response, IL-6 synthesis by myeloid cells, including macrophages and dendritic cells, is triggered upon pathogen recognition through toll-like receptors (TLRs) at the infection or injury site. Crucially, in the adaptive immune response, IL-6 is indispensable for the differentiation of B cells into immunoglobulin-secreting cells, a pivotal player in the differentiation of CD4(+) T cell subsets, and a key factor in the development of T follicular helper (Tfh) cells crucial for germinal-center induction. Additionally, IL-6 is required to drive naive CD4(+) T cells toward the Th17 lineage and plays a crucial role in the proliferation of myeloma cells and the survival of plasmablast cells.
