Immune checkpoint inhibitors and immunosuppressive tumor microenvironment: current challenges and strategies to overcome resistance

The review highlights that the immunosuppressive TME contributes significantly to resistance against ICIs, mediated through various mechanisms. Potential strategies to overcome resistance include modulating the TME by targeting immunosuppressive components, combination therapies, and the identification of predictive biomarkers. Further research and innovative approaches are required to fully understand TME-ICI interactions and change the face of cancer treatment.
