背景说明 |
c-di-AMP是 STING 激动剂,其与 STING 结合,从而激活 TBK3-IRF3 信号传导途径,随后引发 I 型 IFN 和 TNF 产生。 |
生物活性 |
c-di-AMP 是一种 STING 激动剂,能与跨膜蛋白 STING 结合,从而激活 TBK3-IRF3 信号通路。c-di-AMP 也是细菌的第二信使,主要在革兰氏阳性细菌中调节细胞的生长、存活和毒力,同时也调节宿主的免疫反应。[1-3] |
In Vitro |
c-di-AMP binds to specific proteins that regulate pathways in bacterial cells,c-di-AMP also binds to regulatory RNA molecules that control potassium ion channel expression in Bacillus subtilis. c-di-AMP signaling also occurs in eukaryotes,as bacterially produced c-di-AMP stimulates host immune responses during infection through binding of innate immune surveillance proteins.[1] The transcription of IFN-β,IL-1β and autophagy related genes(Atgs)were up-regulated in macrophages after treated with c-di-AMP or bacterial infection.[2] |
In Vivo |
Immunization of BALB/c mice with c-di-AMP stimulates high titers of NP-specific IgG in serum and secretory IgA at mucosal sites.[3] |
