Andrea, 附:英文原文 Title: Vitamin B12 produced by gut bacteria modulates cholinergic signalling Author: Kang, Schroeder, the molecular basis of how gut bacteria modulate host nervous system function is largely unknown. Here we show that vitamin B12-producing bacteria that colonize the intestine can modulate excitatory cholinergic signalling and behaviour in the host Caenorhabditis elegans. Here we demonstrate that vitamin B12 reduces cholinergic signalling in the nervous system through rewiring of the methionine (Met)/S-adenosylmethionine cycle in the intestine. We identify a conserved metabolic crosstalk between the methionine/S-adenosylmethionine cycle and the choline-oxidation pathway. In addition,研究人员发现蛋氨酸/S-腺苷蛋氨酸循环与胆碱氧化途径之间存在保守的代谢交流,从而降低了胆碱能信号的传递,肠道微生物群会影响大脑功能和行为, 本期文章:《自然—细胞生物学》:Online/在线发表 美国麻省大学Mark J. Alkema研究组发现,imToken钱包, we show that metabolic rewiring of these pathways by vitamin B12 reduces cholinergic signalling by limiting the availability of free choline required by neurons to synthesize acetylcholine. Our study reveals a gutbrain communication pathway by which enteric bacteria modulate host behaviour and may affect neurological health.
