BioXcell新品推薦——InVivoMAb anti-mouse IL-27 p28單克隆抗體
研發(fā)背景:
?
MM27.7B1單克隆抗體可與小鼠IL-27的p28亞基反應(yīng),IL-27是IL-6 / IL-12細(xì)胞因子家族的成員之一。 IL-27是異二聚體細(xì)胞因子,由EBI3(Epstein-Barr病毒誘導(dǎo)基因3)蛋白和p28亞基組成,也稱為IL-30。IL-27主要來源于骨髓細(xì)胞,包括巨噬細(xì)胞,炎性單核細(xì)胞,小膠質(zhì)細(xì)胞和樹突細(xì)胞等。這些細(xì)胞可以通過分泌IL-27,響應(yīng)TLR配體和炎性細(xì)胞因子。 IL-27 p28通過IL-27受體(IL-27R)發(fā)出信號,IL-27受體在NK細(xì)胞和活化的T細(xì)胞上大量表達(dá)。另外,在B細(xì)胞和未成熟T細(xì)胞中也有少量表達(dá)。
?
研究表明,IL-27具有促炎和抗炎作用。通過IL-27R信號傳導(dǎo)可以促進(jìn)Th1極化和IFNγ的產(chǎn)生,但也可以抑制Th2和Th17細(xì)胞的分化、增殖并誘導(dǎo)IL-10的表達(dá)。研究已證實(shí)MM27.7B1單克隆抗體在體內(nèi)和體外均具有中和小鼠IL-27生物活性的功能。據(jù)其他文獻(xiàn)報(bào)道,該抗體還可以結(jié)合并抑制人IL-27的功能。
