Article Abstract
Compelling evidence suggests a significant association between antibody-mediated immune responses and multiple sclerosis (MS). However, the exact causal relationships between these immune responses and MS remain unclear. In this study, we conducted a comprehensive examination of the link between antibody-mediated immune responses and MS via Mendelian randomization (MR) analysis to identify specific infectious pathogens potentially involved in the onset and progression of MS. We compared immune cell infiltration between MS patients and control subjects. Furthermore, single-cell sequencing was employed to conduct a comparative analysis of the marker genes associated with each cell subtype between individuals diagnosed with MS and the control cohort. We revealed connections between antibody-mediated immune responses and immune cells, as well as the associations between these immune cells and MS. We discovered that CD3 levels on CD28 CD4 T cells significantly influence MS progression by altering the ratio of human herpesvirus 6 (HHV-6). These findings provide novel insights into the biological mechanisms underlying HHV-6-mediated MS.

Adoptive transfer of third-party donor CMV-specific T cells for refractory cytomegalovirus infection following umbilical cord blood transplantation.

Refractory cytomegalovirus (CMV) infection is a severe complication following umbilical cord blood transplantation (UCBT). Antiviral agents, the standard first-line therapy, are limited by toxicity and resistance without robust T-cell immunity. We evaluated third-party donor (TPD)-derived CMV-specific T cells (CMVSTs) as a treatment option.

Oncometabolites are aberrant metabolic byproducts that arise from mutations in enzymes of the tricarboxylic acid (TCA) cycle or related metabolic pathways and play central roles in tumor progression and immune evasion. Among these, 2-hydroxyglutarate (2-HG), succinate, and fumarate are the most well-characterized, acting as competitive inhibitors of α-ketoglutarate-dependent dioxygenases to alter DNA and histone methylation, cellular differentiation, and hypoxia signaling. More recently, itaconate, an immunometabolite predominantly produced by activated macrophages, has been recognized for its dual roles in modulating inflammation and tumor immunity.

As the field of gene therapy advances and as the importance of sex as a biological variable in shaping viral immune responses is recognized, the impact of sex on adeno-associated virus (AAV) vectors mediated gene therapies remain largely unexplored. Here we review current understanding of the immune response against AAV gene therapy as well as the knowledge of sex differences observed in viral responses. We discuss sex differences in innate immune mechanisms such as Toll-like receptor recognition and complement activation, as well as the functional responses of key immune cells such as dendritic cells, macrophages, and T/B cells that are involved in AAV immunogenicity.

Patients with primary plasma cell leukemia (pPCL), particularly those with extramedullary disease (EMD), face a poor prognosis even with chimeric antigen receptor (CAR)-T cell therapy. This case report describes a patient with relapsed/refractory pPCL and life-threatening malignant pleural effusion (PE) treated with intrapleural CAR-T cells targeting B-cell maturation antigens. CAR-T cell expansion within the PE was observed, along with a rapid reduction in leukemia cell count and PE volume.

Background: Variants of uncertain significance (VUS) represent a major diagnostic challenge in the interpretation of genetic testing results, particularly in the context of inborn errors of immunity such as severe combined immunodeficiency (SCID). The inconsistency among computational prediction tools often necessitates expensive and time-consuming wet-lab analyses.
Objective: This study aimed to develop disease-specific, multi-class machine learning models using in silico scores to classify SCID-associated genetic variants and improve the interpretation of VUS.
