BAFF binds to the tumor necrosis factor receptor-like molecule B cell maturation antigen and is important for maintaining the peripheral B cell population. (1/82)

The tumor necrosis factor (TNF) family member B cell activating factor (BAFF) binds B cells and enhances B cell receptor-triggered proliferation. We find that B cell maturation antigen (BCMA), a predicted member of the TNF receptor family expressed primarily in mature B cells, is a receptor for BAFF. Although BCMA was previously localized to the Golgi apparatus, BCMA was found to be expressed on the surface of transfected cells and tonsillar B cells. A soluble form of BCMA, which inhibited the binding of BAFF to a B cell line, induced a dramatic decrease in the number of peripheral B cells when administered in vivo. Moreover, culturing splenic cells in the presence of BAFF increased survival of a percentage of the B cells. These results are consistent with a role for BAFF in maintaining homeostasis of the B cell population.  (+info)

Interaction of the TNF homologues BLyS and APRIL with the TNF receptor homologues BCMA and TACI. (2/82)

BLyS (also called TALL-1, THANK, or BAFF) [1] [2] [3] [4] is a member of the tumor necrosis factor (TNF) gene family that stimulates proliferation and immunoglobulin production by B cells. BLyS interacts with the TNF receptor (TNFR) homologue TACI (transmembrane activator and CAML-interactor) [5], and treatment of mice with a TACI-Fc fusion protein abolishes germinal center formation after antigenic challenge [6]. Here we report a novel interaction between BLyS and another TNFR homologue, BCMA (B cell maturation antigen) [7] [8]. Further, the TNF homologue APRIL [9], a close relative of BLyS, also bound to BCMA and TACI. BLyS or APRIL activated nuclear factor-kappaB (NF-kappaB) through TACI and BCMA, and each ligand stimulated immunoglobulin M (IgM) production by peripheral blood B cells. These results define a dual ligand-receptor system that may play an important role in humoral immunity.  (+info)

TNF receptor family member BCMA (B cell maturation) associates with TNF receptor-associated factor (TRAF) 1, TRAF2, and TRAF3 and activates NF-kappa B, elk-1, c-Jun N-terminal kinase, and p38 mitogen-activated protein kinase. (3/82)

BCMA (B cell maturation) is a nonglycosylated integral membrane type I protein that is preferentially expressed in mature B lymphocytes. Previously, we reported in a human malignant myeloma cell line that BCMA is not primarily present on the cell surface but lies in a perinuclear structure that partially overlaps the Golgi apparatus. We now show that in transiently or stably transfected cells, BCMA is located on the cell surface, as well as in a perinulear Golgi-like structure. We also show that overexpression of BCMA in 293 cells activates NF-kappa B, Elk-1, the c-Jun N-terminal kinase, and the p38 mitogen-activated protein kinase. Coimmunoprecipitation experiments performed in transfected cells showed that BCMA associates with TNFR-associated factor (TRAF) 1, TRAF2, and TRAF3 adaptor proteins. Analysis of deletion mutants of the intracytoplasmic tail of BCMA showed that the 25-aa protein segment, from position 119 to 143, conserved between mouse and human BCMA, is essential for its association with the TRAFs and the activation of NF-kappa B, Elk-1, and c-Jun N-terminal kinase. BCMA belongs structurally to the TNFR family. Its unique TNFR motif corresponds to a variant motif present in the fourth repeat of the TNFRI molecule. This study confirms that BCMA is a functional member of the TNFR superfamily. Furthermore, as BCMA is lacking a "death domain" and its overexpression activates NF-kappa B and c-Jun N-terminal kinase, we can reasonably hypothesize that upon binding of its corresponding ligand BCMA transduces signals for cell survival and proliferation.  (+info)

B cell maturation protein is a receptor for the tumor necrosis factor family member TALL-1. (4/82)

TALL-1 is a recently identified member of the tumor necrosis factor (TNF) family that costimulates B lymphocyte proliferation. Here we show that B cell maturation protein (BCMA), a member of the TNF receptor family that is expressed only by B lymphocytes, specifically binds to TALL-1. A soluble receptor containing the extracellular domain of BCMA blocks the binding of TALL-1 to its receptor on the plasma membrane and inhibits TALL-1-triggered B lymphocyte costimulation. Overexpression of BCMA activates NF-kappaB, and this activation is potentiated by TALL-1. Moreover, BCMA-mediated NF-kappaB activation is inhibited by dominant negative mutants of TNF receptor-associated factor 5 (TRAF5), TRAF6, NF-kappaB-inducing kinase (NIK), and IkappaB kinase (IKK). These data indicate that BCMA is a receptor for TALL-1 and BCMA activates NF-kappaB through a TRAF5-, TRAF6-, NIK-, and IKK-dependent pathway. The identification of BCMA as a NF-kappaB-activating receptor for TALL-1 suggests molecular targets for drug development against certain immunodeficient or autoimmune diseases.  (+info)

A soluble form of B cell maturation antigen, a receptor for the tumor necrosis factor family member APRIL, inhibits tumor cell growth. (5/82)

A proliferation-inducing ligand (APRIL) is a ligand of the tumor necrosis factor (TNF) family that stimulates tumor cell growth in vitro and in vivo. Expression of APRIL is highly upregulated in many tumors including colon and prostate carcinomas. Here we identify B cell maturation antigen (BCMA) and transmembrane activator and calcium modulator and cyclophilin ligand (CAML) interactor (TACI), two predicted members of the TNF receptor family, as receptors for APRIL. APRIL binds BCMA with higher affinity than TACI. A soluble form of BCMA, which inhibits the proliferative activity of APRIL in vitro, decreases tumor cell proliferation in nude mice. Growth of HT29 colon carcinoma cells is blocked when mice are treated once per week with the soluble receptor. These results suggest an important role for APRIL in tumorigenesis and point towards a novel anticancer strategy.  (+info)

B-cell maturation protein, which binds the tumor necrosis factor family members BAFF and APRIL, is dispensable for humoral immune responses. (6/82)

B-cell maturation protein (BCMA) is a member of the tumor necrosis factor (TNF) receptor family and is expressed in B lymphocytes. BCMA binds two TNF family members, BAFF and APRIL, that stimulate cellular proliferation. BAFF in particular has been shown to influence B-cell survival and activation, and transgenic mice overexpressing BAFF have a lupus-like autoimmune disorder. We have inactivated BCMA in the mouse germ line. BCMA(-/-) mice have normal B-cell development, and the life span of mutant B lymphocytes is comparable to that of wild-type B cells. The humoral immune responses of BCMA(-/-) mice to T-cell-independent antigens as well as high and low doses of T-cell-dependent antigens are also intact. In addition, mutant mice have normal splenic architecture, and germinal centers are formed during an ongoing immune response. These data suggest a functional redundancy of BCMA in B-cell physiology that is probably due to the presence of TACI, another TNF receptor family member that is expressed on B cells and that can also bind BAFF and APRIL.  (+info)

An essential role for BAFF in the normal development of B cells through a BCMA-independent pathway. (7/82)

The B cell activating factor BAFF (BlyS/TALL-1/zTNF4) is a tumor necrosis factor (TNF)-related ligand that promotes B cell survival and binds to three receptors (BCMA, TACI, and the recently described BAFF-R). Here we report an absolute requirement for BAFF in normal B cell development. Examination of secondary lymphoid organs from BAFF-deficient mice revealed an almost complete loss of follicular and marginal zone B lymphocytes. In contrast, mice lacking BCMA had normal-appearing B lymphocyte compartments. BAFF therefore plays a crucial role in B cell development and can function through receptors other than BCMA.  (+info)

BAFF-R, a newly identified TNF receptor that specifically interacts with BAFF. (8/82)

B cell homeostasis has been shown to critically depend on BAFF, the B cell activation factor from the tumor necrosis factor (TNF) family. Although BAFF is already known to bind two receptors, BCMA and TACI, we have identified a third receptor for BAFF that we have termed BAFF-R. BAFF-R binding appears to be highly specific for BAFF, suggesting a unique role for this ligand-receptor interaction. Consistent with this, the BAFF-R locus is disrupted in A/WySnJ mice, which display a B cell phenotype qualitatively similar to that of the BAFF-deficient mice. Thus, BAFF-R appears to be the principal receptor for BAFF-mediated mature B cell survival.  (+info)

Multiple myeloma is a malignant plasma cell disorder diagnosed annually in approximately 86,000 participants worldwide. JNJ-68284528 is an autologous chimeric antigen receptor T-cell (CAR-T) therapy that targets B-cell maturation antigen (BCMA), a molecule expressed on the surface of mature B lymphocytes and malignant plasma cells. The primary hypothesis for this study is that JNJ-68284528 will significantly improve progression free survival (PFS) compared with standard therapy (PVd or DPd), in participants who have previously received 1 to 3 prior line(s) of therapy, that included a proteasome inhibitor (PI) and an immunomodulatory drug (IMiD) and who are refractory to lenalidomide. This study will be conducted in 3 phases: Screening (up to 28 days before randomization), Treatment, and Follow-Up. Assessment like patient-reported outcome(s) (PROs) assessments, electrocardiogram (ECG), vital signs, pharmacokinetic will be performed during the study. Safety evaluations will include review of ...
Chimeric antigen receptor (CAR) T cell therapy has demonstrated proven efficacy in some hematologic cancers. We evaluated the safety and efficacy of LCAR-B38M, a dual epitope-binding CAR T cell therapy directed against 2 distinct B cell maturation antigen epitopes, in patients with relapsed/refractory (R/R) multiple myeloma (MM). This ongoing phase 1, single-arm, open-label, multicenter study enrolled patients (18 to 80 years) with R/R MM. Lymphodepletion was performed using cyclophosphamide 300 mg/m2. LCAR-B38M CAR T cells (median CAR+ T cells, 0.5 × 106 cells/kg [range, 0.07 to 2.1 × 106]) were infused in 3 separate infusions. The primary objective is to evaluate the safety of LCAR-B38M CAR T cells; the secondary objective is to evaluate the antimyeloma response of the treatment based on the general guidelines of the International Myeloma Working Group. At data cutoff, 57 patients had received LCAR-B38M CAR T cells. All patients experienced ≥ 1 adverse events (AEs). Grade ≥ 3 AEs were reported

B-cell activating factor (BAFF), also known as BlyS, TALL-1, TNAK, and zTNF4, is a TNF ligand superfamily member and has been designated TNFSF13B. It is produced by macrophages, dendritic cells, and T lymphocytes. BAFF promotes the survival of B cells and is essential for B cell maturation (1‑4). BAFF binds to three TNF receptor superfamily members: B‑cell maturation antigen (BCMA/TNFRSF17), transmembrane activator and calcium-modulator and cyclophilin ligand interactor (TACI/TNFRSF13B) and BAFF receptor (BAFF R/BR3/TNFRSF 13C). These receptors are type III transmembrane proteins that lack a signal peptide. Whereas TACI and BCMA bind BAFF and another TNF superfamily ligand, APRIL(a proliferation-inducing ligand), BAFF-R selectively binds BAFF. Mouse BAFF-R cDNA encodes a 175 amino acid residue (aa) transmembrane protein with a 71 aa extracellular domain, a 21 aa transmembrane domain, and a 83 aa cytoplasmic region. A second isoform of BAFF R that has a 72 aa cytoplamic region can also be ...
Circulating endothelial progenitor cells (EPCs) are biologic markers of endothelial function. In patients with systemic lupus erythematosus (SLE), the numerical reduction and functional impairment of EPCs contribute to the endothelial dysfunction. Through ex vivo and in vitro studies, we aimed at evaluating the effects of B lymphocyte stimulator (BLyS) on EPC colonies and endothelial cells and also investigating BLyS receptor expression on these cells. EPCs were isolated from peripheral blood mononuclear cells (PBMC). In order to evaluate their ability to form colonies, EPCs were cultured on fibronectin-coated dishes and incubated with BlyS alone or BlyS and belimumab. Apoptosis of EPCs and endothelial cell line EA.hy926 was evaluated after 6, 12, and 24 h of incubation with BLyS and after 6 h with BLyS and belimumab.

Background The TNF superfamily member B lymphocyte stimulator (BLyS), referred to as BAFF, is known to be an effective modulator of peripheral B cell homeostasis that promotes B cell survival and differentiation. BLyS is expressed by a few stromal cells, T cells, and most myeloid cell. BLyS transgenic mice show an expansion of the peripheral mature B cell compartment, hyperglobulinemia, anti-single-stranded DNA and anti-double-stranded DNA antibodies, and circulating immune complexes. A proliferation-inducing ligand (APRIL) is a homolog to BLyS that is expressed by monocytes, macrophages, DCs, T cells, and others. APRIL is virtually undetectable in normal tissues but is strongly expressed in adenocarcinomas and can accelerate the growth of malignant cells in vitro and in vivo. APRIL/BLyS heterotrimers are present in the serum of patients with systemic autoimmune diseases like rheumatoid arthritis (RA), SLE, and SS. APRIL over expression promotes a strong survival signal for both CD4+ and CD8+ T ...

The development and antigen-dependent differentiation of B lymphocytes are orchestrated by an array of growth factors, cytokines, and chemokines that require tight spatiotemporal regulation. Heparan sulfate proteoglycans specifically bind and regulate the bioavailability of soluble protein ligands, but their role in the immune system has remained largely unexplored. Modification of heparan sulfate by glucuronyl C5-epimerase (Glce) controls heparan sulfate-chain flexibility and thereby affects ligand binding. Here we show that Glce deficiency impairs B-cell maturation, resulting in decreased plasma cell numbers and immunoglobulin levels. We demonstrate that C5-epimerase modification of heparan sulfate is critical for binding of a proliferation inducing ligand (APRIL) and that Glce-deficient plasma cells fail to respond to APRIL-mediated survival signals. Our results identify heparan sulfate proteoglycans as novel players in B-cell maturation and differentiation and suggest that heparan sulfate ...
Naive peripheral B cells survive in vivo because of active stimulation by the TNF superfamily ligand B lymphocyte stimulator (BLyS/BAFF). Although the survival promoting properties of BLyS are well known, the signal pathways and molecular effectors that characterize this stimulation are still being elucidated. In this communication, we discuss the signal cascades that effect BLyS dependent survival and the regulation of BLyS induced signaling. We also examine the role of BLyS as a growth factor and propose that BLyS induced metabolic enhancement optimizes the B cell response to BCR and TLR-dependent signaling.

To target APRIL-dependent stimulation of B cell cancers, we recently produced and characterized two monoclonal antagonistic anti-human APRIL antibodies called humanAPRIL.01A (hA.01A) and humanAPRIL.03A (hA.03A). In a first biochemical assay to validate their blocking activity, hA.01A was shown to fully prevent APRIL from binding to its receptors, whereas a substantial difference was detected for hA.03A, which inhibited APRIL binding to BCMA less efficiently than hA.01A. Epitope mapping subsequently revealed that hA.01A and hA.03A bind distinct sites on APRIL, which provided a structural rationale of their different blocking activities. Importantly, this differential inhibition profile can be used to functionally dissect BCMA and TACI-dependent signals and indicated that B cell survival and IgA ...
Είναι το τελευταίο ποίημα του Σεφέρη και δημοσιεύτηκε στο Βήμα (23.9.71) τρεις μέρες μετά το θάνατό του στην περίοδο της δικτατορίας. Το ποίημα βασίζεται σε μια περικοπή του Πλάτωνα (Πολιτεία 614 κ.ε.) που αναφέρεται στη μεταθανάτια τιμωρία των αδίκων και ιδιαίτερα του Αρδιαίου. Ο Αρδιαίος, τύραννος σε μια πόλη, είχε σκοτώσει τον πατέρα του και τον μεγαλύτερο του αδερφό του. Γι αυτό και η τιμωρία του, καθώς και των άλλων τυράννων, στον άλλο κόσμο στάθηκε φοβερή.

Tumor Necrosis Factor Ligand Superfamily Member 13: A member of tumor necrosis factor superfamily found on MACROPHAGES; DENDRITIC CELLS and T-LYMPHOCYTES. It occurs as transmembrane protein that can be cleaved to release a secreted form that specifically binds to TRANSMEMBRANE ACTIVATOR AND CAML INTERACTOR PROTEIN; and B CELL MATURATION ANTIGEN.
B cell-activating factor belonging to the TNF family (BAFF) and its receptor BAFF-R play critical roles in the maturation and survival of conventional peripheral B cells. However, they appeared to be dispensable for the generation and maintenance of CD5(+) B-1 cells as BAFF(-/-) and BAFF-R(-/-) mice have normal B-1 cell populations. Hence, it is presently unclear if B-1 cells are responsive to BAFF and if BAFF regulates some aspects of B-1 cell function. We show here that BAFF-R and transmembrane activator and CAML interactor (TACI) are the major receptors expressed by B-1 cells. Specifically, we show that BAFF treatment of B-1 cells leads to increased NF-kappaB p100 processing and CD21/CD35 expression. Interestingly, toll-like receptor (TLR) engagement of B-1 cells augmented the surface expression of BAFF receptors and rendered them responsive to BAFF costimulation, as evidenced by their increased proliferation, expression of cell surface activation markers and secretion of the pro-inflammatory

Results The mean disease duration of SLE was 7,0 [2,0-10,0] years, SLEDAI 2K score - 4 [2-13], SLICC damage index score - 0 [0-1], current prednisone dose - 10,0 [7,5-25,0] mg/day. SLE pts did not differ from healthy controls in BAFF (0,02 [0,02-0,08] vs 0,02 [0,02-0,02] ng/ml) and APRIL (0,01 [0,01-0,62] vs 0,01 [0,01-0,01] ng/ml) levels. Among SLE pts BAFF level correlated with lupus anticoagulant (r=0,88, p,0,05) and ESR (r=0,43, p,0,05); APRIL level correlated with SLEDAI 2K (r=0,55, p,0,01), CRP (r=0,50, p,0,01), antiDNA (r=0,38, p,0,05), creatinine level (r=0,39, p,0,05), current prednisone dose (r=0,55, p,0,01) and CD19 B lymphocytes absolute count (r=0,89, p,0,05). We divided SLE pts on two groups: the 1st- pts with high activity (SLEDAI 2K≥8), the 2nd - pts with low (SLEDAI 2K,8). The patients of 1st group had higher level of APRIL (1,69 [0,01-4,0] vs 0,01 [0,01-0,01] ng/ml, p,0,05) compared to 2nd group and control, there is no difference in BAFF level in these groups.. ...
BAFF and APRIL are innate immune mediators that trigger immunoglobulin G (IgG) and IgA class-switch recombination (CSR) in B cells by engaging the receptor TACI. The mechanism that underlies CSR signaling by TACI remains unknown. Here we found that the cytoplasmic domain of TACI encompasses a conserved motif that bound MyD88, an adaptor that activates transcription factor NF-kappaB signaling pathways via a Toll-interleukin 1 (IL-1) receptor (TIR) domain. TACI lacks a TIR domain, yet triggered CSR via the DNA-editing enzyme AID by activating NF-kappaB through a Toll-like receptor (TLR)-like MyD88-IRAK1-IRAK4-TRAF6-TAK1 pathway. TACI-induced CSR was impaired in mice and humans lacking MyD88 or the kinase IRAK4, which indicates that MyD88 controls a B cell-intrinsic, TIR-independent, TACI-dependent pathway for immunoglobulin diversification. ...

Introduction Blisibimod is a potent B cell-activating aspect (BAFF) antagonist that binds to both cell membrane-expressed and soluble BAFF. B cells reverted to baseline, resulting in a calculated 30 percent30 % decrease in total B cells by around 160 days following the 1st dosage. In both solitary- and multiple-dosing SC cohorts, the pharmacokinetic profile indicated sluggish absorption, dose-proportional publicity from 0.3 through 3.0 mg/kg SC and 1 through 6 mg/kg IV, linear pharmacokinetics over the dosage selection of 1.0C6.0 mg/kg, and accumulation ratios which range from 2.21 to 2.76. The comparative increase in memory space B cells had not been associated with security signals, as well as the 1192500-31-4 supplier occurrence of adverse occasions, anti-blisibimod antibodies, and medical laboratory abnormalities had been similar between blisibimod- and placebo-treated topics. Conclusions Blisibimod transformed the constituency from the B cell pool and solitary and multiple dosages of ...
