Investigators across the globe have expended considerable effort attempting to identify mechanisms of response and resistance to ICIs. The general conclusion is that each patient’s response to immunotherapy is likely complex and highly individualized.

Despite their promise, checkpoint inhibitors are not effective in every patient, and research suggests the STING (stimulator of interferon genes) pathway may hold important clues as to why some tumors fail to respond.
