炎性體PCR芯片 炎性PCR芯片檢測84個關鍵基因的表達,包括炎性體相關基因,先天免疫的蛋白復合物,以及一般的NOD樣受體(NLR)信號基因。NLRs是一類主要的胞漿內(nèi)模式識別受體(PRR),與細胞表面Toll樣受體一樣,識別多種多樣的病原微生物和免疫原性生物產(chǎn)物。PRR四個家庭成員(AIM2、NLRC4/IPAF、NLRP1和NLRP3)中任何一個的激活,都將引起炎性體的形成。而這些蛋白質(zhì)復合物又反向激活caspase-1,使促炎性細胞因子IL1B、IL18和pyroptosis上調(diào),從而導致炎癥壞死,以及caspase-1依賴的程序性細胞死亡。芯片包括編碼炎性體組件的基因、炎性體功能發(fā)揮的下游信號和抑制基因、其他NLR家庭成員,以及可能形成更多的炎性體和其下游信號的基因。通過實時定量PCR的方法,研究者即能夠利用該芯片簡單可靠地同時檢測炎性體和NLR功能和信號相關的基因表達。Inflammasomes PCR Array Inflammasomes: AIM2: AIM2, CASP1 (ICE), PYCARD (ASC).
