背景(Background)
白細(xì)胞介素-1β(IL-1β)也稱為分解代謝素,是一種細(xì)胞因子蛋白,在人類中由IL1B基因編碼。IL-1β前體被胱天蛋白酶1(白細(xì)胞介素1β轉(zhuǎn)化酶)切割。胞質(zhì)硫醇蛋白酶切割產(chǎn)物形成成熟的IL-1β。
IL1β是結(jié)構(gòu)相關(guān)的多肽,在人類中具有約21%的氨基酸(aa)同一性。這兩種蛋白質(zhì)都是由多種細(xì)胞對炎癥因子、感染或微生物內(nèi)毒素產(chǎn)生反應(yīng)而產(chǎn)生的。雖然IL1α和IL1β獨(dú)立調(diào)節(jié),但它們與同一受體結(jié)合并發(fā)揮相同的生物學(xué)作用。
IL-1β是白細(xì)胞介素1細(xì)胞因子家族的成員。這種細(xì)胞因子是由活化的巨噬細(xì)胞作為前蛋白產(chǎn)生的,其被半胱天冬酶1(CASP1/ICE)蛋白水解處理成其活性形式。這種細(xì)胞因子是炎癥反應(yīng)的重要介質(zhì),參與多種細(xì)胞活動,包括細(xì)胞增殖、分化和凋亡。發(fā)現(xiàn)這種細(xì)胞因子在中樞神經(jīng)系統(tǒng)(CNS)中誘導(dǎo)環(huán)氧合酶-2(PTGS2/COX2)有助于炎癥性疼痛超敏反應(yīng)。該基因和其他8個白細(xì)胞介素1家族基因在2號染色體上形成細(xì)胞因子基因簇。
