Summary: Research showed that almost all seropositive patients and 17.9% of seronegative patients on B cell depleting therapies developed anti-SARS-CoV-2 T cell memory, with functional similarity to controls. Following vaccination, vaccine-specific humoral memory was impaired, but all patients developed a specific T cell response.

Summary: The study indicates that both fingolimod and interferon-beta induce BAFF protein and mRNA expression, leading to a shift in the B cell pool towards a regulatory phenotype. Specifically, BAFF protein correlated with an increase in transitional B cells, decrease in switched B cells, and reduction in B cell-surface BAFF-R expression. However, BAFF does not directly influence the expression of immunoregulatory cytokines IL-10 and IL-35.

Summary: The study found that EBV infection in B cells can lead to the preferential infiltration of CXCR3(+) B cells into the central nervous system in MS patients. Research on transplant recipients and MS patients treated with natalizumab indicated that EBV infection enhances antibody production and brain-homing B cell subsets.

Summary: Multiple Sclerosis (MS) is an inflammatory demyelinating disease of the central nervous system, with B cells emerging as central players in the immune pathogenesis of the disease. Memory B cells (Bmem) are considered key B cell phenotypes in MS due to their antigen-experience, increased lifespan, and rapid response to stimulation.

Summary: Pregnancy can influence the disease course of MS, leading to changes in miRNA expression and immune cell phenotypes, such as downregulation of miRNAs and an increase in monocytes. Additionally, during pregnancy, there is a decrease in NK cells and CD8+ T cells, along with an increase in IL10, PDL1, and PDL2 expression.

Summary: This study found that stimulation of PBMCs with vitamin D followed by steroid has beneficial effects on disease management, but the association between patient serum 25(OH)D-3 and memory B cell proportion differs between MS and NMOSD. Further research with larger patient populations is needed to confirm these findings.

Summary: The production of autoantibodies by autoreactive B cells is crucial in the pathogenesis of lupus. Autophagy plays a key role in maintaining autoreactive memory B cells, and its deficiency leads to a decrease in these cells and a reduction in autoantibody production. Targeting autophagy may be a potential strategy to suppress autoreactive memory B cells and ameliorate humoral autoimmunity.

Summary: This study investigated the longitudinal dynamics of SARS-CoV-2 antibodies and memory B cells in MS patients after vaccination, and their association with the risk of COVID-19. The results showed that certain treatments may decrease antibody levels and the production of memory B cells, increasing the risk of breakthrough infections.

Summary: The separation of B cells into different subsets has provided insights into their diverse functions in immune responses. Advances in single-cell techniques have enabled a deeper understanding of B cell characteristics and functions, though challenges remain. This study offers a reference single-cell dataset for better classification of functional B cell subsets in peripheral blood, highlighting the complexity and diversity of B cell populations.

Summary: During pregnancy, there are significant shifts in NK cell populations, with an increase in CD56(bright) NK cells and a decrease in CD56(dim) NK cells. These changes occur in both pregnant women with multiple sclerosis and healthy pregnant women, potentially contributing to disease amelioration in multiple sclerosis during pregnancy.

Summary: This study investigates the role of B cells in multiple sclerosis (MS) and reveals that MS patients exhibit dysregulation in B cell homeostasis, including increased memory B cells and decreased expression of BAFF-R. The study also demonstrates that reactivation of Epstein Barr Virus (EBV) in MS patients is associated with phenotypic changes in B cells. These findings provide further insights into the pathological mechanisms of MS and the complex role of BAFF/BAFF-R signaling.

Summary: This study aimed to assess whether polygenic risk scores for MS are associated with changes in the blood B-cell compartment in children. The results showed that a naive B-cell-MS-PRS was significantly associated with lower naive B-cell numbers and higher frequencies and absolute numbers of memory B cells in children. The findings suggest that specific genetic risk variants may impact the composition of the blood B-cell compartment during childhood, potentially influencing MS pathophysiology later in life.

Summary: This study systematically quantified ultrastructural and subcellular characteristics of the axon-myelin unit in MS NAWM and found more activated and phagocytic microglia cells and T cells compared to control WM. This study suggests that subclinical alterations to the axon-myelin unit in MS NAWM may contribute to disease progression.

Summary: The T cells in the human brain have a tissue-resident memory T (T-RM) cell phenotype, which is associated with lesions in multiple sclerosis (MS). Our study investigated the transcriptional and functional profile of T cells from white and gray matter. We found that the gene expression hardly differed between lesional and normal-appearing white matter T cells in MS brains. The up-regulated genes in brain T-RM cells included CD20 and osteopontin, which has been shown to inhibit T cell activity.

Summary: This study examined the impact of labor induction at each week of gestation from 37 to 42 weeks on offspring's school performance at age 12. The results showed that induction of labor was associated with decreased school performance scores and a lower proportion of children reaching higher secondary school level. These long-term effects should be taken into account in counseling and decision making.

Summary: This study investigates the association between gestational age, sociodemographic characteristics, and school performance at the age of 12. Results show that longer gestational age is associated with better school performance, regardless of socio-demographic factors. Factors such as maternal education, maternal age, and ethnicity also influence school performance. Preterm children and those from socially or economically disadvantaged backgrounds are more vulnerable to the negative impact of preterm birth on school performance. Caution is needed in interpreting the results due to differential loss to follow-up.

Summary: In this study, researchers explored the maturation of B cells in the central nervous system (CNS) of multiple sclerosis (MS) patients and their association with immunoglobulin production, T-cell presence, and lesion formation. They found that local antibody-secreting cells (ASCs) were associated with mature B cells, focal MS lesions, and increased levels of IgG in the cerebrospinal fluid (CSF). Additionally, they discovered a positive correlation between the presence of ASCs and CD4+ memory T cells in MS lesions. These findings suggest that local B cells in late-stage MS preferentially mature into ASCs, which contribute to intrathecal and local Ig production.

Summary: Multiple sclerosis (MS) is an autoimmune disease that affects the central nervous system (CNS) and results in significant neurodegeneration. A genome-wide association study identified a significant association between the rs10191329 polymorphism in the DYSF-ZNF638 locus and MS severity. This polymorphism was also associated with earlier need for a walking aid and increased brain pathology. Another polymorphism in the DNM3-PIGC locus showed suggestive association with MS, and there was significant heritability enrichment in CNS tissues. Mendelian randomization analyses suggested a potential protective effect of higher educational attainment in MS.

Summary: This study compares the cost-effectiveness and societal benefits of anti-CD20 monoclonal antibodies. The results show that there is no significant difference in cost-effectiveness between ocrelizumab and ofatumumab, suggesting that choosing the cheaper antibody can provide MS care without compromising health benefits.
