Novel Immunotherapy Disrupts the Protective Tumor Microenvironment Ecosystem

Chimeric antigen receptor T-cell therapy - CAR T for short - has been a major advance in treating blood cancers like leukemia and lymphoma. But the immunotherapy has struggled against solid tumors for two main reasons: tumor cells often don't share one consistent surface target, and many solid tumors are protected by a dense network of scar tissue and immune-suppressive cells that blocks T cells.
