WAS Protein Deficiency Disrupts Memory B Cell Formation During Acute LCMV Infection

J Clin Immunol. 2026 Feb 11. doi: 10.1007/s10875-026-01984-5. Online ahead of print. ABSTRACT Wiskott-Aldrich syndrome (WAS) is a rare x-linked monogenic immunodeficiency disease, caused by the mutation of WAS gene encoding WAS protein (WASp). Previous findings in WAS patients show B cell perturbations in the periphery, characterized by diminished B-cell numbers and phenotype abnormalities, including … Read more

Pediatric IPEX-Associated Dermatitis Responds To Dupilumab: Evidence from Skin Transcriptomics and Immune Profiling

J Clin Immunol. 2026 Feb 7. doi: 10.1007/s10875-025-01979-8. Online ahead of print. ABSTRACT PURPOSE: Immunodysregulation, Polyendocrinopathy, Enteropathy, and X-linked (IPEX) syndrome is a rare autoimmune disorder caused by mutations in the FOXP3 gene. Patients with IPEX frequently present with severe dermatitis, diabetes, and enteropathy. This study explores the efficacy of Dupilumab (an anti-IL-4Rα monoclonal antibody) … Read more

αβT/CD19-depleted Allogeneic Stem Cell Transplantation in Adults with Inborn Errors of Immunity

J Clin Immunol. 2026 Feb 3. doi: 10.1007/s10875-025-01978-9. Online ahead of print. ABSTRACT PURPOSE: Allogeneic hematopoietic stem cell transplantation (allo-HSCT) is successful in pediatric patients with inborn errors of immunity (IEI), but its use in adults is complicated by pre-existing organ damage and increased risk of treatment-related mortality. Ex vivo graft engineering using αβTCR/CD19 depletion … Read more

Follicular Helper T Cells and B Cell Maturation in Patients with 22q11.2 Deletion Syndrome and Recurrent Infections

J Clin Immunol. 2026 Feb 3. doi: 10.1007/s10875-026-01987-2. Online ahead of print. ABSTRACT PURPOSE: 22q11.2 Deletion Syndrome has been primarily described as a disorder of T cell production secondary to thymic hypoplasia. However, there is great complexity in the clinical picture with infections, autoimmunity, and inflammation occurring. Emerging evidence suggests that qualitative T cell dysfunction … Read more
