越来越多的证据表明,免疫系统和神经系统之间存在广泛而普遍的相互作用。先前的研究表明,OCTR-1,一种类似于人类去甲肾上腺素受体的神经元G蛋白偶联受体(GPCR),在感觉神经元中起作用,控制秀丽隐杆线虫中微生物杀灭途径和未折叠蛋白反应(UPR)的基因表达。在这里,我们发现OCTR-1表达神经元,ASH,参与控制先天免疫途径。相比之下,另一组OCTR-1表达神经元ASI显示出促进病原体回避行为。我们还确定了神经肽NLP-20和AIA中间神经元,它们负责整合冲突的线索和行为,作为ASH/ASI神经回路的下游组件。这些发现提供了深入了解参与调节病原体防御机制的神经网络在C。elegans和可能有广泛的影响的策略所利用的后生动物,以平衡能源昂贵的免疫激活和行为反应。
Increasing evidence implies an extensive and universal interaction between the immune system and the nervous system. Previous studies showed that OCTR-1, a neuronal G-protein–coupled receptor (GPCR) analogous to human norepinephrine receptors, functions in sensory neurons to control the gene expression of both microbial killing pathways and the unfolded protein response (UPR) in Caenorhabditis elegans. Here, we found that OCTR-1–expressing neurons, ASH, are involved in controlling innate immune pathways. In contrast, another group of OCTR-1–expressing neurons, ASI, was shown to promote pathogen avoidance behavior. We also identified neuropeptide NLP-20 and AIA interneurons, which are responsible for the integration of conflicting cues and behaviors, as downstream components of the ASH/ASI neural circuit. These findings provide insights into a neuronal network involved in regulating pathogen defense mechanisms in C. elegans and might have broad implications for the strategies utilized by metazoans to balance the energy-costly immune activation and behavioral response.
