编码p.C284R和p.I254V蛋白的C13orf31的单核苷酸变异导致系统性幼年特发性关节炎,并分别与麻风病和克罗恩病的风险相关。在这里,我们开始揭示潜在的机制。C13orf31与过氧化物酶体上的脂肪酸合成酶形成复合物,并通过新生脂肪生成促进通量,同时驱动高水平的脂肪酸氧化(FAO)和糖酵解,从而促进ATP再生。依赖c13orf31的FAO控制炎症小体激活、线粒体和NADPH氧化酶依赖的活性氧产生以及巨噬细胞的杀菌活性。p.I254V和p.C284R分别表现出功能下降和丧失,C13orf31决定了机体对内毒素休克的恢复能力。因此,我们发现了巨噬细胞代谢功能和生物能量状态的中心调节因子,这是在进化选择下决定炎症和感染性疾病的风险。
Single nucleotide variation in C13orf31 encoding p.C284R and p.I254V in a protein of unknown function causes systemic juvenile idiopathic arthritis, and associates with risk for leprosy and Crohn’s disease, respectively. Here we set out to uncover the underlying mechanism. C13orf31 formed a complex with fatty acid synthase on peroxisomes and promoted flux through de novo lipogenesis to concomitantly drive high levels of fatty acid oxidation (FAO) and glycolysis, and consequently ATP regeneration. C13orf31-dependent FAO controlled inflammasome activation, mitochondrial and NADPH oxidase-dependent reactive oxygen species production, and bactericidal activity of macrophages. With p.I254V and p.C284R exhibiting decreased and loss of function, respectively, C13orf31 determined organismal resilience to endotoxin shock. We hence discovered a central regulator of macrophage metabolic function and bioenergetic state, which is under evolutionary selection and determines risk for inflammatory and infectious disease.
