Abstract
Chimeric antigen receptor-engineered mesenchymal stem cells (CAR-MSCs) represent a novel and highly adaptable platform for the targeted treatment of inflammatory and autoimmune diseases. By integrating the inflammation-homing and immunomodulatory properties of mesenchymal stem cells (MSCs) with the antigen-specific recognition and activation potential of chimeric antigen receptors (CARs), CAR-MSCs enable site-specific delivery of therapeutic agents directly to inflamed or diseased tissues. This dual functionality enhances therapeutic precision while minimizing off-target effects and systemic toxicity. Recent preclinical studies have demonstrated the efficacy of CAR-MSCs in modulating pathogenic immune responses, reducing local inflammation, and promoting tissue repair in various disease models. CAR-MSCs have been engineered to recognize and interact with disease-specific antigens or inflammatory markers, allowing them to selectively suppress the activation and proliferation of autoreactive immune cells. This targeted immunosuppression offers a promising strategy for restoring immune tolerance without the risks associated with systemic immunosuppression. In this review, we provide a comprehensive overview of recent developments in CAR-MSC design, highlight mechanisms by which CARs enhance MSC functionality, and discuss key challenges, including safety, scalability, and regulatory considerations. Collectively, these emerging approaches hold substantial promise for reshaping future therapies for inflammatory and autoimmune diseases.
