一般描述
半胱天冬酶-1,也称为IL-1β转化酶(ICE),是一种酶,可裂解炎性细胞因子IL-1β和IL-18,从而释放成熟的活性肽。半胱天冬酶-1对于防御病原体很重要,并且它也参与细胞凋亡的诱导。来自半胱天冬酶-1缺陷小鼠的胸腺细胞对Fas介导的细胞凋亡具有抗性,并且半胱天冬酶-1与秀丽隐杆线虫的细胞死亡基因CED-3相似。半胱天冬酶-1是由两个反平行异二聚体组成的异四聚体,每个异二聚体由20 kDa(p20)和10 kDa(p10)亚基形成。该酶具有Tyr-Val-Ala-Asp(YVAD)的优选切割位点。半胱天冬酶-1在脾脏和肺中高表达,而在大脑中则不存在。
特异性
其他同源性:小鼠、大鼠、犬、猪和猫。(92%序列同源性)。
该抗体可识别半胱天冬酶1的p20亚基。由于92%的序列同源性,该抗体可与半胱天冬酶5发生交叉反应。此外,该抗体可识别还原型人半胱天冬酶1亚型的P45酶原(~45 kDa)和p20亚基(~20 kDa)。
免疫原
与人半胱天冬酶1的p20亚基相对应的KLH偶联的线性肽。
表位:p20亚基
应用
免疫组化分析:代表批次的1:1,000稀释液在人脾脏组织中检测到半胱天冬酶1。此外,代表批次的1:4,000稀释液在人结肠组织中检测到半胱天冬酶1。
抗半胱天冬酶1抗体是一种高度特异性的兔多克隆抗体,靶向半胱天冬酶1 & 已通过蛋白质印迹&IHC(石蜡)进行测试。

To study whether pyroptosis is involved in the bilirubin-induced injury of primary cultured rat cortical microglial cells. Primary cultured rat cortical microglial cells were randomly administered with 30 μmol/L bilirubin (bilirubin group), 30 μmol/L bilirubin following 30 μmol/L VX-765 pretreatment

Neuroinflammation is a common pathological feature in a number of neurodegenerative diseases, which is mediated primarily by the activated glial cells. Nucleotide-binding oligomerization domain-like receptor pyrin domain-containing-3 (NLRP3) inflammasome-associated neuroinflammatory response is mostly considered. To investigate the situation of the

Rickettsiae actively escape from vacuoles and replicate free in the cytoplasm of host cells, where inflammasomes survey the invading pathogens. In the present study, we investigated the interactions of Rickettsia australis with the inflammasome in both mouse and human macrophages.
