Single cell analyses reveal the PD-1 blockade response-related immune features in hepatocellular carcinoma

A comparative analysis of the tumor microenvironment (TME) in responders and non-responders is expected to unveil the mechanisms responsible for the immunotherapy resistance and provide potential treatment targets.
