B cells, as progenitors of autoantibody-producing plasma cells and as antigen-presenting cells, play a crucial role in the pathogenesis of these diseases. Despite significant advancements in B-cell-targeting therapies, relapses are common among patients. Evidence of insufficient B-cell depletion by monoclonal antibodies such as rituximab, and the inability to deplete plasma cells, suggest that a more robust and complete B-cell depletion may be necessary for immune-mediated kidney diseases. Chimeric antigen receptor (CAR)-expressing cell therapy has emerged as a promising option. In this approach, immune cells like T cells are genetically engineered to recognize specific markers on B cells. By leveraging T cells' natural ability to infiltrate tissues and their high-affinity target binding, this method enables a deeper clearance of B cells than is usually observed with B-cell depleting monoclonal antibodies. This review explores the potential of using B-cell depleting CAR-expressing cell therapy in the treatment of immune-mediated kidney diseases.</p>","PeriodicalId":7419,"journal":{"name":"American Journal of Kidney Diseases","volume":" ","pages":""},"PeriodicalIF":9.4,"publicationDate":"2025-06-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144245732","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Patients deceased of VITT have been accepted as organ donors despite safety concerns regarding the transmission of VITT to recipients. The outcome of adult kidney graft recipients was reported favorable in most cases, however, (thrombotic) complications were observed more frequently. We present two pediatric recipients of kidney grafts from VITT-deceased patients. Both donors (38 and 34 years old, male, body mass index each 23 kg/m<sup>2</sup>) experienced VITT-related symptoms 22 and 12 days after first dose of Vaxrevia® and Vaccine Janssen®, respectively. Neither had a prior history of other prothrombotic conditions (e.g., history of smoking, arterial hypertension, or prior thrombosis). The graft function was excellent for up to 36 months in the recipient in Case 1 (14-year-old girl, hemodialysis, kidney failure caused by methylmalonic acidemia). However, the recipient in Case 2 (4-year-old boy, peritoneal dialysis, kidney failure caused by abnormal urethral valves) experienced immediate and recurrent renal vein thrombosis. Histopathology of the explanted organ revealed extended platelet-enriched thrombus formation. VITT-causing antibodies against platelet factor 4 were detected in the organ perfusate of both allografts during cold storage with significantly higher concentrations in the latter patient.
