ABSTRACT

The development and successful clinical application of engineered T cells expressing synthetic chimeric antigen receptors (CARs) represents a milestone in cancer therapy. This approach optimizes physiological in vivo T-cell activation against specific target antigens expressed on defined cell subsets with the goal of their deep and sustained depletion. Significant progress has been made in redesigning CAR T-cell constructs to improve patient safety, therapeutic efficacy, and accessibility. Efforts have also focused on streamlining manufacturing to improve availability and reduce costs, two critical challenges to widespread adoption. Beyond hematologic malignancies, CAR T-cell therapies are now increasingly being repurposed to tackle B-cell-mediated autoimmune diseases (AIDs). This is primarily achieved through broad B-cell depletion, but more targeted approaches-such as the selective elimination of autoantibody-producing B-cell subpopulations-are also being explored. Important considerations in their implementation are identifying the most pertinent patient groups, tailoring their treatment up to the point of CAR-infusion, and following up on their unique toxicity-profile. In the context of neurological AIDs-including refractory myasthenia gravis, Lambert-Eaton syndrome, multiple sclerosis, and stiff-person syndrome-early clinical experience suggests promising efficacy and tolerability, leading to a growing number of registered clinical trials. In this review, we provide an overview of the mechanism and evolution of CAR T-cell therapy, highlighting why its application in AIDs, particularly in neurology, represents a highly promising therapeutic strategy.
