Dexamethasone activates anti-tumor immunity in multiple myeloma by dismantling the GR-PPP1CB complex to restore STING/IRF3 signaling
Background
The cyclic GMP-AMP synthase/stimulator of interferon genes (cGAS-STING) pathway mediates anti-tumor immunity by sensing cytosolic DNA and producing type I interferons, but is frequently suppressed in multiple myeloma (MM), enabling immune e…
