β-Interleukin I (163-171), human, an immunostimulatory fragment of human IL-1β peptide, is a T cell activator. β-Interleukin I (163-171), human is not an IL-1R-binding domain of IL-1β. β-Interleukin I (163-171), human is a potent adjuvant that enhances the immune response in a variety of exptl. situations[1][3][4]. | [Biological Activity]
β-interleukin i (163-171), human(c39h64n12o19), a peptide with the sequence val-gln-gly-glu-glu-ser-asn-asp-lys, mw= 1005. interleukins are a group of cytokines (secreted proteins/signaling molecules) that were first seen to be expressed by white blood cells (leukocytes). interleukin 1 alpha and interleukin 1 beta (il-1 alpha and il-1 beta) are cytokines that participate in the regulation of immune responses, inflammatory reactions, and hematopoiesis.interleukin-1 beta (il-1β) also known as catabolin, is a cytokine protein that in humans is encoded by the il1b gene. il-1β precursor is cleaved by caspase 1 (interleukin 1 beta convertase). cytosolic thiol protease cleaves the product to form mature il-1β. il-1β is a member of the interleukin 1 cytokine family. this cytokine is an important mediator of the inflammatory response, and is involved in a variety of cellular activities, including cell proliferation, differentiation, and apoptosis.figure1 formula of b-interleukin i (163-171), humanfigure2 structure of b-interleukin i | [Biochem/physiol Actions]
IL1B (interleukin 1 β) is an immune-activating cytokine. In presence of infection or cell stress, it gets converted into active mature form. | [in vivo]
β-Interleukin I (163-171), human (50 μg, daily, a poorly immunogenic fibrosarcoma (CE-2) of BALB/c mice model) induces a consistent but limited inhibition of tumor growth[2].
β-Interleukin I (163-171), human (1 μmole/kg, i.v.) together with the T-dependent antigen SRBC increases the primary immune response against the antigen[3].
