Photocontrolled immunotherapy: a BODIPY-caged MSA-2 for spatiotemporal activation of STING with visible light
Abstract
The STING pathway is a promising target for cancer immunotherapy, but systemic activation by small-molecule agonists can cause adverse effects. We report a visible light-activatable STING agonist, BODIPY-MSA-2, enabling precise, light-dependent uncaging and restoration of STING activity in vitro, with potential to enable spatiotemporal control of immunostimulation.
