The second messenger c-di-AMP contributes to various homeostatic and stress responses in bacteria. In this issue of , Oberkampf . have identified it as a mediator of osmotic stress and bile salt resistance in the opportunistic pathogen , with additional roles in cell wall homeostasis and biofilm formation.
第二信使 c-di-AMP 有助于细菌的各种动态平衡和应激反应。在本期的 中,Oberkampf 等人发现它是机会性病原体耐渗透压和胆汁盐的介质,在细胞壁动态平衡和生物膜形成方面具有额外的作用。
