STING1 and neoplasm: Combination of αPD‐1 with CPGP demonstrated significant tumour suppression 96.3% compared to free cGAMP. Along with this, more pronounced histological damage was observed compared to other cohorts. In line with the above results, a marked increase in cytokinin levels of approx. 2.7‐fold over CP group was observed activating STING pathway leading to maturation of dendritic cells
