STING1 and neoplasm: In a following study by same group, they used similar strategy that CDA (a STING agonist) was electronically complexed with P‐NT hydrogel (CDA‐NT).[218] It has been reported that the activation of STING pathway in tumor cells could stimulate innate and adaptive immunity within TME.[219] In this study, they conjugated two CPT moieties with iRGD directly through etcSS linker to synthesize diCPT‐iRGD.
