从作为食物来源的细菌中区分致病菌是秀丽隐杆线虫免疫的关键。利用O-linked n -乙酰氨基葡萄糖(O-GlcNAc)循环酶缺陷突变体,我们研究了这种营养感应途径在秀丽隐杆线虫先天免疫应答中的作用。遗传分析表明,O-GlcNAc转移酶(ogt-1)的缺失导致动物对人类病原体金黄色葡萄球菌过敏,而对铜绿假单胞菌不敏感。遗传相互作用研究表明,营养反应性OGT-1通过保守的β-catenin (BAR-1)途径,与p38 MAPK (PMK-1)协同作用,调节对金黄色葡萄球菌的免疫反应。此外,全基因组转录谱分析显示,O-GlcNAc循环突变体表现出独特的应激和免疫应答基因的失调。营养传感器OGT-1参与秀丽隐杆线虫到人类进化中保守的免疫模块,揭示了营养可利用性和病原体特异性免疫反应之间未被探索的联系。
Discriminating pathogenic bacteria from bacteria used as a food source is key to Caenorhabidits elegans immunity. Using mutants defective in the enzymes of O-linked N-acetylglucosamine (O-GlcNAc) cycling, we examined the role of this nutrient-sensing pathway in the C. elegans innate immune response. Genetic analysis showed that deletion of O-GlcNAc transferase (ogt-1) yielded animals hypersensitive to the human pathogen S. aureus but not to P. aeruginosa. Genetic interaction studies revealed that nutrient-responsive OGT-1 acts through the conserved β-catenin (BAR-1) pathway and in concert with p38 MAPK (PMK-1) to modulate the immune response to S. aureus. Moreover, whole genome transcriptional profiling revealed that O-GlcNAc cycling mutants exhibited deregulation of unique stress- and immune-responsive genes. The participation of nutrient sensor OGT-1 in an immunity module evolutionarily conserved from C. elegans to humans reveals an unexplored nexus between nutrient availability and a pathogen-specific immune response.
