炎性小体是激活半胱天冬酶-1的多蛋白复合物,其随后导致促炎细胞因子IL-1β和IL-18的成熟以及焦亡,一种由细菌病原体诱导的细胞死亡形式。Nod样受体家族的成员包括NLRP 1、Nlrp 3和Nlrc 4以及HIN-200家族成员AIM 2是炎性小体的关键组分,并将微生物和内源性危险信号与Caspase-1活化联系起来。响应于微生物感染,炎性体的激活通过诱导限制微生物侵入的免疫应答而有助于宿主保护,但是炎性体的失调激活与自身炎性综合征和其他病理学相关。因此,了解炎性体途径将提供对宿主防御反应系统对微生物和炎症性疾病的发展的见解。
Inflammasomes are multi-protein complexes that activate Caspase-1 which subsequently leads to the maturation of the proinflammatory cytokines IL-1β and IL-18 as well as pyroptosis, a form of cell death induced by bacterial pathogens. Members of the Nod-like receptor family including NLRP1, Nlrp3 and Nlrc4 as well as the HIN-200 family member AIM2 are critical components of the inflammasome and link microbial and endogenous danger signals to Caspase-1 activation. In response to microbial infection, activation of the inflammasomes contribute to host protection by inducing immune responses that limit microbial invasion, but deregulated activation of inflammasomes is associated with autoinflammatory syndromes and other pathologies. Thus, understanding inflammasome pathways will provide insights into the host defense response system against microbes and the development of inflammatory disorders.
