Roseburia intestinalis-derived butyrate alleviates neuropathic pain

Approximately 20% of patients with shingles develop postherpetic neuralgia (PHN). We investigated the role of gut microbiota in shingle- and PHN-related pain. Patients with shingles or PHN exhibited significant alterations in their gut microbiota with microbial markers predicting PHN development among patients with shingles. Functionally, fecal microbiota transplantation from patients with PHN to mice heightened pain sensitivity. Administration of Roseburia intestinalis, a bacterium both depleted in patients with shingles and PHN, alleviated peripheral nerve injury-induced pain in mice. R. intestinalis enhanced vagal neurotransmission to the nucleus tractus solitarius (NTS) to suppress the central amygdala (CeA), a brain region involved in pain perception. R. intestinalis-generated butyrate activated vagal neurons through the receptor, G protein-coupled receptor 41 (GPR41). Vagal knockout of Gpr41 abolished the effects of R. intestinalis on the NTS-CeA circuit and reduced pain behaviors. Overall, we established a microbiota-based model for PHN risk assessment and identified R. intestinalis as a potential pain-alleviating probiotic.

期刊介绍： Cell Host & Microbe is a scientific journal that was launched in March 2007. The journal aims to provide a platform for scientists to exchange ideas and concepts related to the study of microbes and their interaction with host organisms at a molecular, cellular, and immune level. It publishes novel findings on a wide range of microorganisms including bacteria, fungi, parasites, and viruses. The journal focuses on the interface between the microbe and its host, whether the host is a vertebrate, invertebrate, or plant, and whether the microbe is pathogenic, non-pathogenic, or commensal. The integrated study of microbes and their interactions with each other, their host, and the cellular environment they inhabit is a unifying theme of the journal. The published work in Cell Host & Microbe is expected to be of exceptional significance within its field and also of interest to researchers in other areas. In addition to primary research articles, the journal features expert analysis, commentary, and reviews on current topics of interest in the field.
