Fig. 3

(A) The activation of STING pathway by cytoplasmic delivery of cGAMP using 93-O17S-F. (B) Subcellular distribution of cGAMPFluo and lysosome in RAW264.7 and DC2.4 cells after incubation of free cGAMPFluo or 93-O17S-F/cGAMPFluo for 4 hours. (C and D) Relative expressions of ifnb1 (C) and cxcl10 (D) genes in RAW264.7 and DC2.4 cells after incubation of 93-O17S-F/cGAMP for 4 hours. n = 6, *P ≤ 0.05, **P ≤ 0.01, and ***P ≤ 0.001. (E) The concentration of IFN-β in the medium of DC2.4 cells after incubation of 93-O17S/cGAMP for 4 and 24 hours. n = 4.
