这篇讲什么
本文报道了在斑马鱼幼鱼中,肠内分泌细胞在淋巴细胞定植肠道之前产生IL-22,通过塑造肠道微生物群(增加乳杆菌科丰度)并促进ghrelin表达来驱动肠道蠕动,且这一功能在小鼠早期生命中保守。

Feijoo4,5, Gerard Eberl3, German Sumbre2, Jos Boekhorst11, Sylvia Brugman11, Pedro P. Hernandez1* The gut microbiota, immune system, and enteric nervous system interact to regulate adult gut physiology. However, the mechanisms establishing gut physiology during development remain unknown. We report that in developing zebrafish, enteroendocrine cells produced interleukin-22 (IL-22) in response to microbial signals before lymphocytes populated the gut. In larvae, IL-22 shaped the gut microbiota, increasing Lactobacillaceae abundance and ghrelin expression to promote gut motility. …
