A complex partnership between the host and the vast intestinal microbial ecosystem serves numerous biological activities including nutrition, immunity, and barrier function. In this issue of Immunity, Singh et al. (2014) demonstrate that microbial-derived butyrate mediated its protective activity against inflammation and colorectal cancer through GPR109a signaling.
宿主与庞大的肠道微生物生态系统之间存在着复杂的相互关系,为众多生物学活动提供服务,包括营养、免疫和屏障功能。在本期《免疫》杂志中,Singh 等人(2014)证明了微生物衍生的丁酸盐通过 GPR109a 信号传导发挥其抗炎和结直肠癌保护作用。
