The purpose of the present study is to compare results from the 12-item General Functioning Scale (GF-FAD) of the Family Assessment Device (FAD) to a three-item version, the Brief Assessment of Family Functioning Scale (BAFFS), designed to be used when brevity is especially important. We used principal components analysis of the GF-FAD, followed by multiple sample confirmatory factor analyses to test the robustness of the BAFFS in different samples. The BAFFS correlated highly with the GF-FAD, and demonstrated good concurrent validity with another measure of global marital functioning, the Dyadic Adjustment Scale-4 in a help-seeking sample...

Berberine (BBR) is an isoquinoline alkaloid derived from various medicinal herbs. Previous studies have suggested that BBR exerts antimicrobial, antitumor, and antidiabetic effects and can be used to treat Helicobacter pylori-induced chronic gastritis. However, the exact mechanism by which BBR inhibits H. pylori infection is not fully understood. We investigated the anti-inflammatory properties and potential mechanism of BBR in H. pylori-infected mice with chronic gastritis. We found that BBR can suppress the expression of pro-inflammatory genes IL-6, TGF-β, and IL-1β and upregulate anti-inflammatory gene IL-10 expression in the mucosa and RAW 264...

Beyond the production of autoantibodies, B-cells are thought to play a role in systemic sclerosis (SSc) by secreting proinflammatory/profibrotic cytokines. B-cells are a heterogeneous population with different subsets distinguished by their phenotypes and cytokine production. Data about B-cell subsets, cytokine production and intracellular pathways leading to this production are scarce in SSc. The aim of our study was to describe B-cell homeostasis, activation, proliferation, cytokine production in B-cells and serum and B-cell intracellular signaling pathways in SSc...

NF-κB-inducing kinase (NIK) mediates non-canonical NF-κB signaling downstream of multiple TNF family members, including BAFF, TWEAK, CD40, and OX40, which are implicated in the pathogenesis of systemic lupus erythematosus (SLE). Here, we show that experimental lupus in NZB/W F1 mice can be treated with a highly selective and potent NIK small molecule inhibitor. Both in vitro as well as in vivo, NIK inhibition recapitulates the pharmacological effects of BAFF blockade, which is clinically efficacious in SLE...

INTRODUCTION: A proliferation-inducing ligand (APRIL) and B cell activation factor (BAFF) are known to play a significant role in the pathogenesis of several diseases, including BAFF in malaria. The aim of this study was to investigate whether APRIL and BAFF plasma concentrations could be part of inflammatory responses associated with P. vivax and P. falciparum malaria in patients from the Brazilian Amazon. METHODS: Blood samples were obtained from P. vivax and P...

IgA nephropathy (IgAN) is characterized by high serum IgA levels and IgA deposition in the renal mesangium. Recent research has indicated that pathogenic IgA may originate from affected tonsils, where present enhancement of IgA production by IgA class switching and immuno-activation. Tripterygium Wilfordii (TW) was found to be especially effective in IgAN by its' immunosuppression effect. Given this background, we investigated the mechanisms underlying the role of TW in the generation of IgA and IgA class switching in tonsillar GCs of IgAN patients...

Hematopoietic humanized mice (hu-mice) have been developed to study the human immune system in an experimental in vivo model, and experiments to improve its performance are ongoing. Previous studies have suggested that the impaired maturation of human B cells observed in hu-mice might be in part due to inefficient interaction of the human B-cell-activating factor (hBAFF) receptor with mouse B-cell-activating factor (mBAFF), as this cytokine is an important homeostatic and differentiation factor for B lymphocytes both in mice and humans...

Immune thrombocytopenic purpura (ITP) is an idiopathic bleeding disorder. B cell activating factor (BAFF) and 'A proliferation-inducing ligand' (APRIL) have regulatory effects on B and T cells and may represent relevant factors in the pathogenesis of ITP. Serum levels and gene expression were investigated in ITP patients. Both BAFF and APRIL serum levels were significantly elevated in active ITP. However, gene expression analysis revealed both factors to have a tendency toward downregulation. Glucocorticoid treatment significantly reduced BAFF but not APRIL serum levels, which may be mediated by differences in transcription factor binding sites...

BACKGROUND: The essential function of B cell-activating factor (BAFF) is regulating the survival and differentiation of B cells. The link between pretransplant BAFF levels and pretransplant alloimmunization and its value to predict subsequent acute antibody-mediated rejection (AMR) and outcome after renal transplantation is not fully understood. METHODS: Objective of our retrospective single-center study was to determine, by ELISA analysis of pretransplant serum BAFF levels in 249 patients undergoing renal transplantation, association between preformed anti-human leukocyte antigen (HLA) antibodies, occurrence of acute antibody mediated rejection (AMR) and renal allograft survival...

The ability to engineer primary human B cells to differentiate into long-lived plasma cells and secrete a de novo protein may allow the creation of novel plasma cell therapies for protein deficiency diseases and other clinical applications. We initially developed methods for efficient genome editing of primary B cells isolated from peripheral blood. By delivering CRISPR/CRISPR-associated protein 9 (Cas9) ribonucleoprotein (RNP) complexes under conditions of rapid B cell expansion, we achieved site-specific gene disruption at multiple loci in primary human B cells (with editing rates of up to 94%)...

BACKGROUND: Non-adherence has been associated with reduced graft survival. The aim of this study was to investigate the immunological mechanisms underlying chronic renal allograft rejection using a model of non-adherence to immunosuppressive therapy. We used a MHC (major histocompatibility complex) -mismatched rat model of renal transplantation (Brown Norway to Lewis), in which rats received daily oral cyclosporine A. In analogy to non-adherence to therapy, one group received cyclosporine A on alternating days only...

B-cell maturation antigen (BCMA) was originally identified as a cell membrane receptor, expressed exclusively on late stage B-cells and plasma cells (PCs). Investigations of BCMA as a target for therapeutic intervention in multiple myeloma (MM) were initiated in 2007, using cSG1 as a naked antibody (Ab) as well as an Ab-drug conjugate (ADC) targeting BCMA, ultimately leading to ongoing clinical studies for previously treated MM patients. Since then, multiple companies have developed anti-BCMA-directed ADCs...

This review summarises a number of current insights into the pathogenesis of SLE. On the basis of the interaction of environmental factors within a predisposed host, a chronic autoimmune process gains function with a positive feed-forward loop between innate and adaptive immunity. A current focus of SLE pathogenesis is on the enhanced production of certain cytokines, such as type I interferons and BLyS/BAFF, suggesting continuous plasmacytoid dendritic and myeloid cell activity together with disturbances of B lineage cells (increased autoantibodies, including anti-dsDNA and plasmablasts, which correlate with SLE activity and memory B-cell abnormalities)...

PURPOSE: Monoclonal antibodies (mAbs) such as anti-CD20 rituximab, are proven therapies in B-cell malignancies, yet many patients develop resistance. Novel therapies against alternative targets are needed to circumvent resistance mechanisms. We sought to generate mAbs against human B-cell activating factor receptor (BAFF-R/TNFRSF13C), which has not yet been targeted successfully for cancer therapy. EXPERIMENTAL DESIGN: Novel mAbs were generated against BAFF-R, expressed as a natively folded cell-surface immunogen on mouse fibroblast cells...

Although oligoclonal bands in the cerebrospinal fluid have been a hallmark of multiple sclerosis diagnosis for over three decades, the role of antibody-secreting cells in multiple sclerosis remains unclear. T and B cells are critical for multiple sclerosis pathogenesis, but increasing evidence suggests that plasma cells also contribute, through secretion of autoantibodies. Long-lived plasma cells are known to drive various chronic inflammatory conditions as e.g. systemic lupus erythematosus, however, to what extent they are present in autoimmune central nervous system inflammation has not yet been investigated...

With the goal to design effective HIV vaccines, intensive studies focused on broadly neutralizing antibodies, which arise in a fraction of HIV-infected people. Apart from identifying new vulnerability sites in the viral envelope proteins, these studies have shown that a fraction of these antibodies are produced by self/poly-reactive B-cells. These findings prompted us to revisit the B-cell differentiation and selection process during HIV/SIV infection and to consider B-cells as active players possibly shaping the helper T-cell program within germinal centers (GCs)...

Humoral immunity requires B cells to respond to multiple stimuli, including antigen, membrane and soluble ligands, and microbial products. Ets family transcription factors regulate many aspects of haematopoiesis, although their functions in humoral immunity are difficult to decipher as a result of redundancy between the family members. Here we show that mice lacking both PU.1 and SpiB in mature B cells do not generate germinal centers and high-affinity antibody after protein immunization. PU.1 and SpiB double-deficient B cells have a survival defect after engagement of CD40 or Toll-like receptors (TLR), despite paradoxically enhanced plasma cell differentiation...

Nuclear factor κ-light-chain-enhancer of activated B cells (NF-κB) is known to play an important role in the pathogenesis of chronic lymphocytic leukemia (CLL). Several NF-κB inhibitors were shown to successfully induce apoptosis of CLL cells in vitro Since the microenvironment is known to be crucial for the survival of CLL cells, herein, we tested whether NF-κB inhibition may still induce apoptosis in these leukemic cells in the presence of protective stromal interaction. We used the specific NF-κB inhibitor dehydroxymethylepoxyquinomicin (DHMEQ)...

Systemic administration of corticosteroid (CS) remains the standard gold treatment for pemphigus. However, because of several long-term adverse effects, steroid-sparing agents are usually prescribed in combination with CSs. Despite the high number of available studies, the choice of best drugs to treat pemphigus remains controversial. Therapeutic approaches for pemphigus can be divided into traditional treatment and emerging ones. Personalized medicine, which aims to increase the efficacy as well as reduce adverse effects of treatments, could be considered as the future option...

Intestinal immunoglobulins (Igs) protect against microbes. However, the regulation of intestinal Ig production is poorly understood. In this study, we have investigated the roles of APRIL (tumor necrosis factor superfamily member [TNFSF] 13) and BAFF (TNFSF13B) in intestinal Ig induction. Peyer's patches (PPs) are, at least in part, an inductive site for Igs, including IgA. Introducing APRIL and BAFF in vivo lowered the frequency of IgG1(+) or IgG2b(+) B cells in PPs. Administration of TACI-Fc upregulated the frequency of IgG1(+), IgG2b(+), and IgA(+) B cells in PPs, suggesting that APRIL and BAFF attenuate Ig production in these regions...
