cGAMP can enhance the antigen-specific proliferative capacity of mouse splenocytes [1].
cGAMP can directly activate dendritic cells from both mice and humans in vitro [1].
Under cGAMP stimulation, the transcription of IFNB1 increased in the fibroblasts of patients, but there was no increase in the transcription of genes encoding interleukin-1 (IL1), interleukin-6 (IL6), or tumor necrosis factor (TNF). [2].
cGAMP activates the endoplasmic reticulum (ER)-resident receptor STING, thereby inducing an antiviral state and the secretion of type I interferons.
