Our immune system has the ability to detect and fight infectious pathogens. It can also detect when normal cells become cancerous and kill those cells, preventing cancer progression. But over time, cancers can evolve and evade the immune response.
Researchers have been investigating several potential avenues to counter tumor immunosuppression and re-activate the immune system. One of these is CAR-T therapy, which is designed to harness the potent cytotoxicity of T cells by re-engineering their surface receptors to recognize and attack tumors.
