树突状细胞(DC)利用模式识别受体检测微生物并激活保护性免疫。这些细胞和受体被认为以全有或全无的方式运作,存在于免疫活跃或非活跃状态。在这里,我们报告,接触微生物产品和自我编码的氧化磷脂(OxPAPC)诱导DC激活状态增强,我们称之为“过度活跃”。高活性的DC可诱导强大的适应性免疫反应,并由caspase-11(一种结合oxPAPC和细菌脂多糖(LPS)的酶)激发。OxPAPC和脂多糖通过不同的结构域与caspase-11结合,诱导不同的炎症体依赖活性。两种脂类均可诱导依赖于caspase-11的白介素1的释放,但只有内毒素可诱导下垂。因此,先天免疫系统的细胞和受体可以达到不同的激活状态,这可能允许对感染做出上下文相关的反应。
Dendritic cells (DCs) utilize pattern recognition receptors to detect microorganisms and activate protective immunity. These cells and receptors are thought to operate in an all-or-none manner, existing in an immunologically active or inactive state. Here, we report that encounters with microbial products and self-encoded oxidized phospholipids (oxPAPC) induce an enhanced DC activation state, which we call “hyperactive.” Hyperactive DCs induce potent adaptive immune responses and are elicited by caspase-11, an enzyme that binds oxPAPC and bacterial lipopolysaccharide (LPS). oxPAPC and LPS bind caspase-11 via distinct domains and elicit different inflammasome-dependent activities. Both lipids induce caspase-11–dependent interleukin-1 release, but only LPS induces pyroptosis. The cells and receptors of the innate immune system can therefore achieve different activation states, which may permit context-dependent responses to infection.
