Research summary

The study investigates cGAS–STING pathway activation in tumors. In genO-BRGSF-HIS mice, STING activation reprogrammed human myeloid cells to promote pro-inflammatory cytokine production, dendritic cell maturation, and T cell-mediated tumor killing.

Key outcome of the study

STING agonist treatment triggered strong human innate responses, boosted T cell infiltration, and improved tumor control in humanized mice.
