Taxonomy: Mechanism Branch / Architecture. Workflows sit above the mechanism and technique branches rather than replacing them.
Summary
Chimeric antigen receptor T-cell (CAR-T) therapy is a novel form of adoptive cellular immunotherapy that involves modifying autologous T cells to recognize and target tumor-associated antigens (TAAs) on malignant cells, independent of major histocompatibility complex (MHC) restriction.

It requires genetically engineered T cells and a CAR-T architecture. Its function is shaped by cytokine- and growth factor-mediated signaling networks.; requires genetically engineered T cells; performance depends on cytokine and growth factor signaling context; clinical application in solid tumors faces multiple challenges; requires strategies to improve fitness, potency, persistence, and tumor targeting in solid tumors; The approach requires autologous T cells and a CAR-engineering process to retarget them against tumor-associated antigens. Its use also depends on identifying suitable target antigens in the tumor.; requires modification of autologous T cells; depends on suitable tumor-associated antigens
The abstract indicates that CAR-T still faces limitations related to exhaustion, toxicity, and the immunosuppressive tumor microenvironment.; efficacy and limitations are governed by cytokine- and growth factor-mediated signaling networks; The abstract states that CAR-T therapy in solid tumors still faces tumor heterogeneity, an immunosuppressive tumor microenvironment, and safety concerns.; tumor heterogeneity; immunosuppressive tumor microenvironment; safety concerns; The abstract states that it does not by itself overcome poor tumor trafficking, weak expansion and persistence, antigen loss or heterogeneity, or immunosuppressive TME effects in solid tumors.; limited efficacy in solid tumors; insufficient trafficking to tumors; limited expansion and persistence; tumor relapse due to antigen loss or heterogeneity; immunosuppressive tumor microenvironment dampens function; The abstract indicates that CAR-T therapy remains limited in solid tumors because of insufficient tumor-specific antigens and the complexity of the tumor microenvironment.
