J Clin Immunol. 2025 Nov 28. doi: 10.1007/s10875-025-01966-z. Online ahead of print. ABSTRACT PURPOSE: Despite well-conducted replacement therapy with polyvalent immunoglobulins (IgRT), some patients with primary immunodeficiencies (PID) continue to experience recurrent or chronic infections. IgA and IgM, essential for mucosal and complement-mediated immunity, are absent or minimal in standard immunoglobulin products. The aim of … Read more

J Clin Immunol. 2025 Nov 28. doi: 10.1007/s10875-025-01965-0. Online ahead of print. ABSTRACT Exosomes, as integral mediators of cellular communication, have emerged as crucial players in the pathogenesis and potential treatment of autoimmune diseases. This review explores the dual role of exosomes in mediating autoantigen presentation and their impact on immune dysregulation. Exosomes, by virtue … Read more

J Clin Immunol. 2025 Nov 27. doi: 10.1007/s10875-025-01919-6. Online ahead of print. ABSTRACT Autosomal recessive mutations in TAP1, TAP2, TAPBP, or B2M, are associated with major histocompatibility complex (MHC) class I deficiency. Individuals may present with granulomatous skin ulceration, but the underlying antigenic triggers remain largely unknown. We identified TAP1 deficiency in a 32-year-old female … Read more

J Clin Immunol. 2025 Nov 25;45(1):168. doi: 10.1007/s10875-025-01963-2. ABSTRACT BACKGROUND: Common Variable Immunodeficiency (CVID) is a group of heterogeneous disorders with common denominators of impaired antibody production and function, and recurrent infections. Currently, prognostic biomarkers for CVID are limited. CXCL13 is a critical regulator of germinal centre responses and antibody production, with T follicular helper … Read more

J Clin Immunol. 2025 Nov 25;45(1):167. doi: 10.1007/s10875-025-01957-0. ABSTRACT Down syndrome (DS) and STAT1 gain-of-function (GOF) share clinical and molecular features, including persistent inflammation. We aimed to investigate whether the coexistence of DS and a STAT1 GOF mutation in a patient synergistically enhances interferon (IFN) signaling and exacerbates inflammatory responses, posing additional management challenges. Two … Read more

J Clin Immunol. 2025 Nov 25;45(1):166. doi: 10.1007/s10875-025-01945-4. ABSTRACT BACKGROUND: Newborn screening (NBS) by quantification of T-cell receptor excision circles (TREC) identifies a considerable number of infants with T-cell lymphopenia (TCL) other than severe combined immunodeficiency (SCID). While some of these children have well-defined inborn errors of immunity (IEI), many lack a clear genetic diagnosis, … Read more

J Clin Immunol. 2025 Nov 26. doi: 10.1007/s10875-025-01961-4. Online ahead of print. ABSTRACT BACKGROUND AND OBJECTIVES: Ankylosing spondylitis (AS) is a chronic immune-mediated inflammatory disease primarily affecting the axial skeleton. Despite significant advances, its pathogenic mechanisms remain unclear, posing challenges to early diagnosis and effective treatment. This study aims to elucidate the pathogenic pathways of … Read more

J Clin Immunol. 2025 Nov 23. doi: 10.1007/s10875-025-01947-2. Online ahead of print. ABSTRACT INTRODUCTION: Inborn errors of immunity (IEIs) constitute a diverse group of more than 500 disorders resulting from pathogenic variants in over 500 causative genes, with most being monogenic diseases. The use of exome sequencing based on next-generation sequencing technologies has significantly advanced … Read more

J Clin Immunol. 2025 Nov 18;45(1):163. doi: 10.1007/s10875-025-01964-1. ABSTRACT PURPOSE: This study aimed to investigate the spectrum of bacterial infections in children with inborn error of immunity (IEIs). METHODS: Pediatric patients with IEIs and positive for bacteria considered to be pathogenic were included in this retrospective study. RESULTS: In this study, 1811 medical records of … Read more
