Article Abstract

The role of B cells in central nervous system (CNS) autoimmunity was initially highlighted by successful clinical trials of anti-CD20 monoclonal antibodies in multiple sclerosis (MS). Research in MS as well as in aquaporin 4 (AQP4)-IgG neuromyelitis optica (NMO) and myelin oligodendrocyte glycoprotein (MOG) antibody-associated disorder (MOGAD) has expanded our appreciation of the contribution of B cells in multiple CNS autoimmune diseases. B cells have multiple functions in the initiation and propagation of CNS autoimmunity that extend beyond autoantibody production, including bidirectional interactions with T cells via B-cell antigen presentation. A deeper understanding of the cooperation between B cells and T cells in MS, NMO, and MOGAD should permit the development of more effective therapies across CNS autoimmune disorders.

Objective: To develop a novel prognostic scoring system for severe cytokine release syndrome (CRS) in patients with B-cell acute lymphoblastic leukemia (B-ALL) treated with anti-CD19 chimeric antigen receptor (CAR)-T-cell therapy, aiming to optimize risk mitigation strategies and improve clinical management.

Methods: This single-center retrospective cohort study included 125 B-ALL patients who received anti-CD19 CAR-T-cell therapy from January 2017 to October 2023. These cases were selected from a cohort of over 500 treated patients on the basis of the availability of comprehensive baseline data, documented CRS grading, and at least 3 months of follow-up.

Overcoming barriers to referral for CAR T-cell therapy in patients with non-Hodgkin aggressive B-cell lymphomas: A Delphi consensus.

Chimeric antigen receptor (CAR) T-cell therapy has revolutionized the treatment of aggressive B-cell non-Hodgkin lymphoma, particularly in relapsed/refractory large B-cell lymphoma and mantle cell lymphoma. Despite its transformative potential, significant challenges persist in optimizing patient identification and referral pathways to ensure timely and equitable access. This expert consensus, developed through the Delphi methodology, analyzes key barriers to the referral process and proposes structured solutions to enhance collaboration between referring treatment centers (RTCs) and qualified treatment centers (QTCs).

B-cell maturation antigen (BCMA)-directed chimeric antigen receptor (CAR) T-cell therapies have revolutionized the approach and management of relapsed/refractory multiple myeloma (RRMM), and as of 2025, idecabtagene vicleucel (ide-cel) and ciltacabtagene autoleucel (cilta-cel) are the only BCMA-targeted CAR T-cell therapies approved by the FDA. Exceptional responses were demonstrated for heavily pretreated patients in the KarMMa-1 trial, reporting a 73% overall response rate (ORR) and 98% in the CARTITUDE-1 trial. Furthermore, both therapies show a significant improvement in progression-free survival (PFS) compared to standard regimens when administered in earlier lines.

NSG-SGM3 humanized mouse models are well-suited for studying human immune physiology but are technically challenging and expensive. We previously characterized a simplified NSG-SGM3 mouse, engrafted with human donor CD34 hematopoietic stem cells without receiving prior bone marrow ablation or human secondary lymphoid tissue implantation, that still retains human mast cell- and basophil-dependent passive anaphylaxis responses. Its capacities for human antibody production and human B cell maturation, however, remain unknown.

Background: Chimeric antigen receptor T-cell (CAR-T) therapy has transformed the treatment landscape for relapsed or refractory non-Hodgkin lymphoma, achieving a 5-year overall survival rate of 40-50%. However, relapse remains a major challenge, especially due to CD19-negative clones. Epcoritamab, a bispecific antibody targeting CD20 and CD3, offers a potential solution for post-CAR-T relapse; however, clinical data in this setting remain limited, particularly in Japan.
