Fig. 4 cGAS-STING pathway is essential for TMZ and anti-CD47 induced immune response. a Combination TMZ and anti-CD47 antibody treatment against murine GBM cells (GL261) increased the production of type I interferons in APCs. IFNA interferon alpha , IFNB interferon beta . n = 5, ** p < 0.01, one-side ANOVA with Bonferroni post hoc correction. b Western blot showing combined TMZ and anti-CD47 antibody treatment resulted in the activation of cGAS-STING cytoplasmic DNA sensing pathways in BM APCs. c Combination TMZ and anti-CD47 antibody treatment promoted p65 expression and nuclear translocation in BM APCs that is dependent on STING. d STING activation is critical to the increased the production of NF-kappaB cytokine TNFalpha and IL1beta in APCs in the setting of combined TMZ and anti-CD47 antibody treatment. n = 6, ** p < 0.01, unpaired Student''s t test. e Immunofluorescence staining of GL261 tumors implanted in WT and STING KO animals. Nuclear p-IRF3 (Ser 396) in CD45 + cells is indicative of STING signaling activation. f , g Quantification of CD45 + cell infiltration and percentage of p-IRF3 positive CD45 + , C57BL/6, n = 7; knockout, n = 6. Unpaired Student''s t test. h GL261 tumor volume in C57BL/6 or STING KO mice at day 20 following control or combination TMZ + aCD47 treatment, n = 5/group. i T-cell infiltration in GL261 tumors in C57BL/6 or STING KO mice at day 20 following control or combination TMZ + aCD47 treatment measured by CD3 + cells in total DAPI count per fie
