IgA production in MHC class II-deficient mice is primarily a function of B-1a cells. (1/1715)

Mice deficient in MHC class II expression (C2d mice) do not make antibody to protein antigens administered systemically, but their ability to produce IgA antibody to antigen administered at mucosal sites has not been described. We investigated IgA production by C2d mice and their IgA antibody response to antigen given orally. Young C2d mice had normal amounts of serum IgA, intestinal-secreted IgA and normal numbers of intestinal IgA plasma cells, compared to control C57BL/6 mice. IgA production by C2d mice increased with age. Following oral immunization with cholera toxin, C57BL/6 mice responded with IgA and IgG antibody, and had increased numbers of IgA plasma cells, but C2d mice gave no response. The Peyer's patch and mesenteric lymph node tissues of C2d mice contained very few CD4-expressing T cells. Thus, C2d mice have no typical mucosal CD4 Th cells and cannot respond to a strong oral immunogen, yet they still produced and secreted IgA. We hypothesized that B-1 lymphocytes could provide a source of IgA independent of antigen-specific T cell help. Young C2d mice had normal numbers of peritoneal B-1a cells and their frequency increased with age. To test the role of these B-1a cells, we bred C2d mice to obtain mice that had no MHC class II expression and expressed the Xid gene that confers deficiency in B-1a cells. These double-deficient mice had 10-fold less serum and secreted IgA than all other F2 littermates. We conclude that B-1a cells are essential for the majority of IgA production in C2d mice. Thus, the C2d mouse may provide a useful tool for analysis of the role of intestinal IgA provided by B-1a cells.  (+info)

An alternatively spliced form of CD79b gene may account for altered B-cell receptor expression in B-chronic lymphocytic leukemia. (2/1715)

Several functional anomalies of B-chronic lymphocytic leukemia (B-CLL) cells may be explained by abnormalities of the B-cell receptor (BCR), a multimeric complex formed by the sIg homodimer and the noncovalently bound heterodimer Igalpha/Igbeta (CD79a/CD79b). Because the expression of the extracellular Ig-like domain of CD79b has been reported to be absent in the cells of most CLL cases, we have investigated the molecular mechanisms that may account for this defect. Peripheral blood lymphocytes (PBL) from 50 patients and two cell lines (MEC1, MEC2) obtained from the PBL of one of them were studied. MEC1, MEC2, and 75% of CLL cases did not express detectable levels of the extracellular Ig-like domain of CD79b, which was nevertheless present in greater than 80% CD19(+) cells from normal donors. In healthy subjects the expression of CD79b was equally distributed in CD5(+) and CD5(-) B-cell subsets. Reverse transcription-polymerase chain reaction (RT-PCR) analysis of CD79b RNA from all patients and from MEC1 and MEC2 cell lines consistently yielded two fragments of different size (709 bp and 397 bp). The 709-bp band corresponds to CD79b entire transcript; the 397-bp band corresponds to an alternatively spliced form lacking exon 3 that encodes the extracellular Ig-like domain. Both fragments were also visible in normal PBL. The expression of the 397-bp fragment was increased in normal activated B cells, while no difference was seen between CD5(+) and CD5(-) B cells. To obtain a more accurate estimate of the relative proportions of the two spliced forms, a radioactive PCR was performed in 13 normal and 22 B-CLL samples and the results analyzed using a digital imager. The mean value of the CD79b to the CD79b internally deleted ratio was 0.64 +/- 0.20 SD in normal donors and 0.44 +/- 0.27 SD in B-CLL (P =.01). Direct sequencing of 397-bp RT-PCR products and of genomic DNA corresponding to exon 3 from MEC1, MEC2, their parental cells, and five fresh B-CLL samples did not show any causal mutation. Single-strand conformation polymorphism analysis of exon 3 performed in 18 additional B-CLL cases showed a single abnormal shift corresponding to a TGT --> TGC polymorphic change at amino acid 122. We propose a role for the alternative splicing of CD79b gene in causing the reduced expression of BCR on the surface of B-CLL cells. As normal B cells also present this variant, the mechanism of CD79b posttranscriptional regulation might reflect the activation stage of the normal B cell from which B-CLL derives.  (+info)

Anti-phospholipid antibodies and CD5+ B cells in HIV infection. (3/1715)

This cross-sectional study evaluates the correlation between anti-phospholipid antibodies and CD5+ B cells in 110 patients infected with HIV-1. There were 89.1% of the patients who had IgG antibodies against cardiolipin and phosphatidylserine. The prevalence of IgM and IgA antibodies was < 22%. AIDS was associated with lower frequencies of IgM antibodies against cardiolipin (P = 0.05) and IgG-antibodies against cardiolipin and phosphatidylserine (P = 0.011). Drug users had higher IgM antibodies against phospholipids than patients from other risk groups (P = 0.02). A history of thromboembolic events was not accompanied by higher levels of anti-phospholipid antibodies (P > 0.2). No correlation between anti-phospholipid antibodies and CD5+ B cells was detected. Percentage part of CD5+ B lymphocytes was elevated in all patients and absolute CD4+ T lymphocyte counts and HIV p24 antigen were inversely correlated. In advanced disease a significant reduction of anti-phospholipid antibodies was contrasted with persistent elevation of CD5+ B lymphocytes. These observations may reflect immunological dysfunction involving apoptosis and endothelial damage rather than polyclonal B cell hyperstimulation. A possible explanation would be that in HIV infection an increased rate of spontaneous apoptosis in peripheral blood lymphocytes is accompanied by functional and structural changes of mitochondria. Therefore, structurally altered mitochondrial phospholipids could serve as antigen to induce specific humoral immune responses.  (+info)

Cutting edge: recruitment of the CD19/CD21 coreceptor to B cell antigen receptor is required for antigen-mediated expression of Bcl-2 by resting and cycling hen egg lysozyme transgenic B cells. (4/1715)

Recruitment of the CD19/CD21 coreceptor is thought to lower the threshold for effective signaling through the B cell Ag receptor. We provide evidence supporting a second role for coreceptor recruitment, and that is to enhance the survival/proliferative potential of the responding B cells. We show that B cell Ag receptor signaling in the absence of coreceptor recruitment induces cellular accumulation of the anti-apoptotic protein Bcl-xL, whereas CD19-mediated signals are required for Bcl-2 accumulation. The expression of both anti-apoptotic proteins correlates with the enhanced responsiveness of both resting and cycling B cells to growth-promoting signals delivered through CD40. These results provide further evidence for the necessity of coreceptor recruitment during Ag-dependent B cell activation and indicate that Ags derived from inflammatory sites function as better thymus-dependent Ags than their counterparts not coated with complement fragments.  (+info)

Antigen receptor engagement selectively induces macrophage inflammatory protein-1 alpha (MIP-1 alpha) and MIP-1 beta chemokine production in human B cells. (5/1715)

We show herein that B cell Ag receptor (BCR) triggering, but not stimulation by CD40 mAb and/or IL-4, rapidly induced the coordinated expression of two closely related T cell chemoattractants, macrophage inflammatory protein-1 beta (MIP-1 beta) and MIP-1 alpha, by human B cells. Naive, memory, and germinal center B cells all produced MIP-1 alpha/beta in response to BCR triggering. In contrast to MIP-1 alpha/beta, IL-8, which is spontaneously produced by germinal center B cells but not by naive and memory B cells, was not regulated by BCR triggering. Culturing follicular dendritic cell-like HK cells with activated B cells did not regulate MIP-1 alpha/beta production, but it did induce production of IL-8 by HK cells. Microchemotaxis assays showed that CD4+CD45RO+ T cells of the effector/helper phenotype actively migrated along a chemotactic gradient formed by BCR-stimulated B cells. This effect was partially blocked by anti-MIP-1 beta and anti-CC chemokine receptor 5 Ab, but not by anti-MIP-1 alpha Ab suggesting that MIP-1 beta plays a major role in this chemoattraction. Since maturation of the B cell response to a peptide Ag is mostly dependent on the availability of T cell help, the ability of Ag-stimulated B cells to recruit T cells via MIP-1 alpha/beta, may represent one possible mechanism enabling cognate interactions between rare in vivo Ag-specific T and B cells.  (+info)

Age-dependent altered proportions in subpopulations of tonsillar lymphocytes. (6/1715)

Age-related changes in functional subsets of lymphocytes may influence the potential to build up immune responses. In particular, the capacity of tonsillar lymphocytes to counter infections may be altered during ageing. In order to address this question we investigated the proportional distribution of several subsets of tonsillar T and B cells with regard to ageing. Tonsils were derived from 119 patients between 2 and 65 years of age. Lymphocyte subsets were monitored by three-colour fluorescence of relevant CD markers in flow cytometry. As a general tendency the percentage of CD3+ T cells steadily increased whereas that of CD19+ B cells decreased at the same time. No significant differences were observed between lymphocytes of patients with and without inflammatory history of the tonsils. The percentage of CD8+ T cells declined whereas that of CD4+ T cells increased during the same time span. CD45RA+ T cells increased during the first two decades of life and gradually decreased thereafter. In contrast, CD45RO+ T cells showed an opposite trend. No differences were seen in the population of CD3-/CD56+ natural killer (NK) cells. The mature B cell marker CD40 showed no significant changes during ageing. However, CD38+ B cells, representing B cells of late maturation stages, dramatically declined up to the age of 65. In a similar manner the CD5+ subpopulation of B cells decreased during ageing. Substantial changes in major tonsillar T and B cell populations as shown in this study may have an impact on the ageing process of the immune system.  (+info)

The evolutionarily conserved sequence upstream of the human Ig heavy chain S gamma 3 region is an inducible promoter: synergistic activation by CD40 ligand and IL-4 via cooperative NF-kappa B and STAT-6 binding sites. (7/1715)

Germline C gamma gene transcription is a crucial event in the process that leads to switch DNA recombination to IgG, but its regulation in the human is poorly understood. We took advantage of our monoclonal model of germinal center B cell differentiation, IgM+ IgD+ CL-01 cells, to define the role of the I gamma 3 evolutionarily conserved sequence (ECS) in the germline transcriptional activation of the human C gamma 3 gene. The I gamma 3 ECS lies upstream of the major I gamma 3 transcription initiation site and displays more than 90% identity with the corresponding human I gamma 1, I gamma 2, and I gamma 4 regions. Reporter luciferase gene vectors containing the human gamma 3 ECS were used to transfect CL-01 cells, which have been shown to undergo Smu-->S gamma 3 DNA recombination, upon engagement of CD40 by CD40 ligand (CD40L) and exposure to IL-4. In these transfected CL-01 cells, CD40:CD40L engagement and exposure to IL-4 synergistically induced gamma 3 ECS-dependent luciferase reporter gene activation. Targeted mutational analysis demonstrated that a tandem NF-kappa B/Rel binding motif is critical for the gamma 3 ECS responsiveness to both CD40L and IL-4, while a STAT-6-binding site is additionally required for IL-4 inducibility. Electrophoretic mobility shift assays showed that p50/p65/c-Rel and STAT-6 are effectively induced by CD40L and IL-4, respectively, and bind to specific DNA motifs within the ECS. These partially overlapping CD40L and IL-4 responsive elements are functionally cooperative as the disruption of one of them prevents synergistic promoter activation. Thus, the gamma 3 ECS is an inducible promoter containing cis elements that critically mediate CD40L and IL-4-triggered transcriptional activation of the human C gamma 3 gene.  (+info)

Syndecan-4 is expressed by B lineage lymphocytes and can transmit a signal for formation of dendritic processes. (8/1715)

Our previous studies indicated that stromal cell-derived syndecan-4 might mediate some form of communication with pre-B cells in bone marrow. We now report additional aspects of this recognition and show that syndecan-4 is also present on pre-B cells. Indeed, the molecule is acquired at an early stage of differentiation and retained until mature B cells undergo Ig isotype switching. mAbs developed to two portions of the syndecan-4 protein core were used to probe possible functions on B lineage lymphocytes. Syndecan-4 ligation had no obvious influence on B lymphocyte formation or activation, but this treatment caused a dramatic morphological change in appropriately stimulated leukocytes. Extended filopodia appeared on transfected Ba/F3 or FDCP-1 cells, as well as activated B cell blasts that were placed on syndecan-4 Ab-coated surfaces. The dendritic processes contained polymerized actin as well as pp52(LSP1), a prominent F-actin binding protein in lymphocytes. The cytoplasmic domain of syndecan-4 was not required for this response. Shape changes of this type could facilitate interactions between B lymphocytes and other components of the immune system. Not only is syndecan-4 a useful marker for discriminating normal B lineage lymphocyte subsets, but our results suggest new ways for the syndecans to participate in immune responses.  (+info)

AU - Riley, Richard L. PY - 2003/10/1. Y1 - 2003/10/1. N2 - Senescence in murine models is associated with a reduction, albeit heterogeneous, in bone marrow pre-B cells. We have categorized aged BALB/c mice into two phenotypes based on their patterns of pre-B/pro-B cell loss. Each phenotype is characterized by distinct responses to the growth cytokine IL-7 and capacity for survival in vitro. A moderate loss of late-stage pre-B cells (25-80%) coincided with decline in proliferation to rmIL-7. This was also associated with a decrease in the frequency of pro-B cells which increased phosphotyrosine content upon IL-7 stimulation, an indicator of early activation events. A severe loss of pre-B cells (,80%) resulted in a reduced pro-B cell pool which retained normal activation and proliferative ...

The development of an effective Ab response to TD Ag requires collaboration between T and B cells. Several lines of evidence support the idea that the ability of B cells to induce both naive T cell priming and tolerance depends on their resting vs activated state (28, 29, 30, 39, 40, 41, 42, 43, 44). In agreement with previous results, we found that both resting MZ and FO B cells were unable to induce T cell responses in vivo and in vitro. However, within a few hours of in vivo Ag priming, MZ B cells were far superior to FO B cells in the activation of naive CD4+ T cells in vitro. MD4 B cell populations have been shown to be a little different in the phenotype of their subsets, in that IgM on FO B cells tended to persist at higher levels than on FO B in normal mice. However, we sorted FO and MZ B cell subsets based on their expression of CD23 and CD21. In this respect the MZ B cells are clearly distinguishable from their FO counterparts. Despite this anomaly in MD4 transgenic mice MZ and FO B ...

The mechanisms that establish immune tolerance in immature and mature B cells appear to be distinct. Membrane-bound autoantigen is thought to induce developmental arrest and receptor editing in immature B cells, whereas mature B cells have shortened lifespans when exposed to the same stimulus. In this study, we used Emu-bcl-2-22 transgenic (Tg) mice to test the prediction that enforced expression of the Bcl-2 apoptotic inhibitor in B cells would rescue mature, but not immature, B cells from tolerance induction. To monitor tolerance to the natural membrane autoantigen H-2Kb, we bred 3-83mudelta (anti-Kk,b) Ig Tg mice to H-2(b) mice or to mice expressing transgene-driven Kb in the periphery. In 3-83mudelta/bcl-2 Tg mice, deletion of autoreactive B cells induced by peripheral Kb antigen expression in the liver (MT-Kb Tg) or epithelia (KerIV-Kb Tg), was partly or completely inhibited, respectively. Furthermore, Bcl-2 protected peritoneal B-2 B cells from deletion mediated by acute antigen exposure, ...

The uniqueness of each BCR and width of the B cell repertoire are due to the DNA rearrangements at HC and LC loci. B cells leave the bone marrow at the transitional stage carrying a wide array of germline-encoded and randomly assembled Ig genes. Transitional B cells migrate with the blood to the spleen. They are not fully functional in the immune responses: they are not able to respond to inflammatory chemokines, and engagement of the BCR leads to their apoptotic cell death. These are safety measures against autoreactivity preventing self-reactive transitional B cells from further development and migration to sites rich in cytokines and stimulatory cells. In contrast to the mortal effect of BCR cross-linking, engagement of TLR9 leads to differentiation of transitional B cells. In response to CpG, a fraction of the transitional B cells (26%) proliferates and acquires the phenotype of memory B cells or directly matures into plasma cells. The remaining cells start to express the markers of ...

In the past decade, the suppressive effects, mainly through the secretion of IL-10, of regulatory B cells on inflammatory responses have been reported in a variety of immune disorders (33-36). Additionally, immune regulation through the interaction of immune cells with the intrinsic phenotype of regulatory B cells (e.g., CD1dhiCD5+, T2-MZP, Tim-1+, and CD9+) were demonstrated in various diseases, and it plays a critical role in autoimmune diseases (37). In recent studies, functional studies in cancer diseases are emerging (38-40). In particular, the change of the distribution of regulatory B cells in cancer tissue is considered to one of important indicators (8-10). Emerging evidence suggests that regulatory B cells suppress effector immune cells including IFN-γ-producing cytotoxicity cells in various cancer diseases through the secretion of IL-10 (11). Although regulatory B cells have to play the suppressive role on the effector function of T cells in autoimmune diseases to cure diseases (41), ...

Rapid response of marginal zone B cells to viral particles. - ImmunologyRapid response of marginal zone B cells to viral particles. - Immunology
Marginal zone (MZ) B cells are thought to be responsible for the first wave of Abs against bacterial Ags. In this study, we assessed the in vivo response of MZ B cells in mice immunized with viral particles derived from the RNA phage Qbeta. We found that both follicular (FO) and MZ B cells responded to immunization with viral particles. MZ B cells responded with slightly faster kinetics, but numerically, FO B cells dominated the response. B1 B cells responded similarly to MZ B cells. Both MZ and FO B cells underwent isotype switching, with MZ B cells again exhibiting faster kinetics. In fact, almost all Qbeta-specific MZ B cells expressed surface IgG by day 5. Histological analysis demonstrated that a population of activated B cells remain associated with the MZ, probably due to the elevated integrin levels expressed by these cells. Thus, both MZ and FO B cells respond with rapid proliferation to viral infection and both populations undergo isotype switching, but MZ B cells remain in the MZ and may be

New insights into human B cell biology - Blizard InstituteNew insights into human B cell biology - Blizard Institute
New insights into human B cell biology. B cells are highly important white blood cells known as lymphocytes and are part of the adaptive immune system. B cells have a specialised receptor on their cell surface (B cell receptor, BCR) which recognises specific proteins. Upon activation, B cells produce antibodies which bind antigens like e.g. molecules from pathogens or vaccines. The drawback of a vast range of different B cell receptors is the potential that some of the receptors recognise self-antigens which can then result in auto-immune disorders. The bone marrow continuously releases immature B cells into the blood stream. A high proportion of these so-called transitional B cells are able to recognise self-antigens via their BCR. It has been unknown where in the body these auto-reactive cells are checked and removed from the circulation. A recent publication by Anna Vossenkämper and Jo Spencer (Kings College) tracked the fate of human transitional B cells and identified that these cells ...

Notch2 interaction with its ligand, Dll1, is required in the mouse to drive MZP into the MZB cell lineage (Saito et al., 2003; Hozumi et al., 2004). Preliminary data based on humanized mouse models have also proposed a Notch2 dependence for the differentiation of IgM+IgD+CD27+ B cells (Scheeren et al., 2008). Accordingly, we searched for an MZP in the spleen from young children, taking as diagnostic criteria its capacity to acquire an MZ phenotype when cultured in presence of OP9 cells expressing human DLL1, a differentiation which, moreover, should be specifically inhibited in presence of anti-NOTCH2 blocking antibodies. This precursor subset was identified using the recently described MEM55 antibody, which marks a glycosylated variant of the CD45RB molecule, harbored by CD27+ B cells and an immature B cell subset (Koethe et al., 2011). Surprisingly, these MZPs were further characterized as expressing the ABCB1 transporter reported so far as the unique hallmark of naive B cells (Wirths and ...

Characterization of antigen processing and presentation by resting B l by Edmund J. Gosselin, Hans-Peter Tony et al.Characterization of antigen processing and presentation by resting B l by Edmund J. Gosselin, Hans-Peter Tony et al.
The production of antibody to a thymus-dependent Ag requires cooperation between the B cell and an Ag-specific Th cell. MHC restriction of this interaction implies that the Th cell recognizes Ag on the B cell surface in the context of MHC molecules and that the Ag-specific B cell gets help by acting as an APC for the Th cell. However, a number of studies have suggested that normal resting B cells are ineffective as APC, implying that the B cell must leave the resting state before it can interact specifically with a Th cell. Other studies, including our own with rabbit globulin-specific mouse T cell lines and hybridomas, show that certain T cell lines can be efficiently stimulated by normal resting B cells. One possible explanation for the above contradiction is that our B cells have become activated before presentation. Here we show that presentation by size-selected small B cells is not the result of nonspecific activation signals generated by the T cells or components of the medium. Also, although LPS

Preventing an identity crisis in the immune systemPreventing an identity crisis in the immune system
As with people, identity is vital to cells. When a cell loses its identity, it can stop working properly and a range of illnesses can result. The immune system, which protects our bodies from disease, includes cells with many different identities. When these cells lose their identity it can cause certain cancers or increase the risk of infections.. Complex networks of signals and genes create and maintain the identity of different cells. New research from the Babraham Institute, Cambridge and the University of Birmingham has revealed how a protein called ZFP36L1 helps cells known as marginal zone B cells (MZ B cells) to maintain their identity.. For cells, identity describes how they are adapted to have a specialised function. Blood cells are specialised for transportation, nerve cells for communication and the immune system fights infections. Each cell becomes specialised to do its job as a result of unique combinations of genetic instructions, which influence how the cell works.. MZ B cells ...

SLE patients with high levels of TLR7 (TLR7hi group) showed an expansion of CD19+CD38highCD24highCD10+ TR B cells. Overall, frequencies of TR B cells positively correlated with the levels of TLR7, but not TLR9. SLE patients, carrying a risk G allele, had increased TLR7 expression and TR cell frequencies, compared to non-risk allele carriers. TLR7hi SLE patients showed increased autoantibody titers and skewing towards Sm/RNP antigens. Upon IFNα priming, TR B cells up-regulated TLR7 and differentiated into plasmablasts in response to TLR7-ligand stimulation. ...

Results Exogenously added IL-7 did not activate B cells directly, in line with the absence of surface IL-7R. However, in the presence of T cells, IL-7 activated both T and B cells (Ki67+ CD4 cells from 1.1±0.2% to 14.4±3.7%, p,0.01 and Ki67+ B cells from 1.9±0.3% to 4.1±0.9%, p,0.05). TLR7A induced B cell activation, as measured by increased proliferation (%Ki67 from 1.2±0.2% to 9.3±1.4%) and up regulation of activation markers on B cells, which was facilitated in the presence of monocytes. TLR7-induced B cell activation in T/B or T/B/monocyte co-cultures was not associated with T cell activation. IL-7 added to TLR7A synergistically increased both B cell (TLR7A vs. IL-7/TLR7A; 9.3±1.4% vs. 33.4±7.3%) and T cell proliferation (IL-7 vs. IL-7/TLR7A; 0.8±0.1% vs. 29.2±5.2%), which for B cells again was further increased by monocytes (TLR7A vs. IL-7/TLR7A; 30.2±8.9% vs. 63.0±8.0%). Similar results were observed for activation marker expression on B cells (CD19, HLA-DR CD25) and on T cells ...

B-1 cell - WikipediaB-1 cell - Wikipedia
B1 cells are a sub-class of B cell lymphocytes that are involved in the humoral immune response. They are not part of the adaptive immune system, as they have no memory, but otherwise, B1 cells perform many of the same roles as other B cells: making antibodies against antigens and acting as antigen presenting cells. Notably, most B1 cells do not develop into memory B cells. B1b cells have been shown to be capable of memory responses. See B1b lymphocytes confer T cell-independent long-lasting immunity. B1 cells are first produced in the fetus and most B1 cells undergo self-renewal in the periphery, unlike conventional B cells (B2 cells) that are produced after birth and replaced in the bone marrow. In January 2011, human B1 cells were found to have marker profile of CD20+CD27+CD43+CD70- and could either be CD5+ or CD5-, which has been debated since. CD5-CD72 is thought to mediate B cell-B cell interaction. B-1 B cells, in the mouse, can be further subdivided into B-1a (CD5+) and B-1b (CD5−) ...

To determine the phenotype of isolated B cells and differentiation on day 14 of culture, a gating strategy was developed for analysis of cells by flow cytometry. After debris and doublets were excluded, viable CD19+ cells were selected and analyzed for the proportions of naive and memory cells according to their CD27 and IgD expression. Viable plasma cells were determined as CD138+CD38+ cells. B cells cultured with the kit seemed to resemble untreated B cells in their subset distribution. The amounts of naive B cells decreased on day 14. This is in line with reports describing that naive B cells have a shorter survival rate. In contrast, the amounts of non-switched memory B cells increased in both the unstimulated culture and the culture expanded by the B Cell Expansion Kit indicating a greater survival capacity of this subset.. ...

This study demonstrates that patients with active, untreated IgG4-RD have significant elevations in their circulating plasmablast counts regardless of their serum IgG4 concentrations, and that patients with multi-organ IgG4-RD have higher absolute plasmablast counts than those with involvement of only one or two organs. In addition, plasmablast levels appear to be superior to serum IgG4 concentrations as a biomarker for IgG4-RD. Plasmablast counts decline swiftly following peripheral B cell depletion, and this decline is accompanied by corresponding decreases in disease activity as measured by the IgG4-RD RI. IgG4-RD thus represents an unusual example of an immune-mediated condition in which measurement of a single cell type may play a central role in diagnosing, monitoring and managing the disease.. The identification of circulating plasmablast expansion in IgG4-RD has substantial implications for clinical care. The diagnosis of IgG4-RD remains dependent upon biopsy and is therefore subject to ...

B cells are crucial players in the human immune system which secrete antibodies that can eliminate bacterial antigens. An agent-based model is implemented to study the behaviour between B cell-antigen interactions during a bacterial infection. We have determined that infection in the system occurs when 69% of antigens are eliminated. Cellular lifetime of B cells plays a role in clearing the antigens, exhibiting three distinct phases - the lag phase, exponential growth phase, and the stationary phase. A Gompertz curve fit demonstrates that the B cell population curve mimics a biologically realistic phenomena. Studying the population dynamics of the system shows that B cell population peaks at around 60%-70% of antigens are eliminated, further supporting the determined point of infection.. ...

Maintenance of Serological Memory by Polyclonal Activation of Human Memory B Cells | ScienceMaintenance of Serological Memory by Polyclonal Activation of Human Memory B Cells | Science
Stimulation by antigen through the B cell receptor (BCR) followed by cognate T cell help drives proliferation and differentiation of antigen-specific naı̈ve B lymphocytes into memory B cells and plasma cells (1, 2). Memory B cells carrying somatically mutated immunoglobulin (Ig) genes survive in secondary lymphoid organs in the absence of antigen (3) and mediate secondary immune responses upon rechallenge. In contrast, plasma cells are terminally differentiated, nondividing cells that home to spleen and bone marrow and are the main source of antibody, which they secrete at a high rate. Mouse plasma cells can be long-lived and are able to sustain antibody production for several months in the absence of memory B cells or antigen (4, 5). However, it is less likely that long-lived plasma cells produced during an immune response will maintain a constant supply of specific antibody over a human life-span, because even long-lived plasma cells would eventually need to be replenished over a human ...

Secretory IgA (S-IgA) is a hallmark antibody principally produced at mucosal sites and plays an important role in the creation of immunological surveillance and homeostasis at mucosa. In addition to the IgA induction through gut-associated lymphoid tissues (e.g., Peyers patch), peritoneal B cells have been considered to be another source of S-IgA, especially specific for the T-independent antigen. Here we show that the trafficking of peritoneal B cells is principally regulated by sphingosine 1-phosphate (S1P). Peritoneal B cells expressed high levels of the type 1 S1P receptor. Thus, disruption of S1P-mediated signaling caused a rapid disappearance of peritoneal B cells. These changes did not affect natural plasma antibody production or phosphorylcholine (PC)-specific antibody production in serum after peritoneal immunization with heat-killed streptococcal pneumoniae. However, it dramatically reduced peritoneal B cell-derived natural intestinal S-IgA production without affecting the expression ...

Antibody affinity maturation occurs in germinal centers (GCs) through iterative rounds of somatic hypermutation and selection. Selection involves B cells competing for T cell help based on the amount of antigen they capture and present on their MHC class II (MHCII) proteins. How GC B cells are able to rapidly and repeatedly transition between mutating their B cell receptor genes and then being selected shortly after is not known. We report that MHCII surface levels and degradation are dynamically regulated in GC B cells. Through ectopic expression of a photoconvertible MHCII-mKikGR chimeric gene, we found that individual GC B cells differed in the rates of MHCII protein turnover. Fluctuations in surface MHCII levels were dependent on ubiquitination and the E3 ligase March1. Increases in March1 expression in centroblasts correlated with decreases in surface MHCII levels, whereas CD83 expression in centrocytes helped to stabilize MHCII at that stage. Defects in MHCII ubiquitination caused GC B cells to

Immunity to individual group A rotavirus (RV), a major cause of viral gastroenteritis in infants, involves B lymphocytes that provide RV-specific antibodies. VP7 interactions with B cells were mediated by surface immunoglobulins and probably by their Fab portions. VP7-reactive B lymphocytes were mainly detected from RV-experienced patients and almost exclusively in the CD27-positive memory cell fraction. Conversely, VP6-reactive B lymphocytes were detected at comparable and high frequencies in adult, infant, and neonate samples. In adult samples, VP6 reacted with about 2% of the CD27-unfavorable (CD27neg) naive B cells. These results demonstrated that this VP6 RV protein interacted with a large fraction of naive B lymphocytes from both adults and neonates. We propose that naive B cell-VP6 conversation might impact the power and quality from the obtained immune system response and really should be looked at for elaborating RV vaccine strategies. Individual group A rotavirus (RV) is regarded as a ...

Polyclonal B cell response - WikipediaPolyclonal B cell response - Wikipedia
A naive (or inexperienced) B cell is one which belongs to a clone which has never encountered the epitope to which it is specific. In contrast, a memory B cell is one which derives from an activated naive or memory B cell. The activation of a naive or a memory B cell is followed by a manifold proliferation of that particular B cell, most of the progeny of which terminally differentiate into plasma B cells;[note 8] the rest survive as memory B cells. So, when the naive cells belonging to a particular clone encounter their specific antigen to give rise to the plasma cells, and also leave a few memory cells, this is known as the primary immune response. In the course of proliferation of this clone, the B cell receptor genes can undergo frequent (one in every two cell divisions)[8] mutations in the genes coding for paratopes of antibodies. These frequent mutations are termed somatic hypermutation. Each such mutation alters the epitope-binding ability of the paratope slightly, creating new clones of ...

CD19 and BAFF‐R can signal to promote B‐cell survival in the absence of Syk | The EMBO JournalCD19 and BAFF‐R can signal to promote B‐cell survival in the absence of Syk | The EMBO Journal
We show here that approximately 25% of the mature peripheral B cells can survive in the mouse for at least 2 months without Syk, in a manner that requires BAFF‐R and CD19 signaling. In contrast, deletion of the Syk gene in early B cells results in the appearance of a small number of immature IgM+ B cells, which, however, fail to give rise to any mature B cells in the periphery (Cheng et al, 1995). Thus, pre‐B and mature B cells have different requirements for Syk. Indeed, the pre‐BCR is an autonomously signaling receptor that continuously engages Syk, whereas the BCR forms an autoinhibited oligomer on mature B cells that is not in contact with Syk. This notion is supported by a proximity ligation analysis showing that Syk is localized near the BCR only after BCR activation (Infantino et al, 2010; Klasener et al, 2014).. The presence of large amounts of Syk‐negative mature B cells in the induced mb1‐CreERT2;Sykfl/fl mice allowed us to analyze the in vivo role of this kinase in the ...

B-cell | Pathway MedicineB-cell | Pathway Medicine
B-cells go through a variety of stages during their development which is discussed in B-cell Development. However, the major functionally important stages to be aware of are the final stages known as the Plasma Cell and Memory B Cell stages. Plasma Cells are B-cells specialized for high levels of antibody synthesis and secretion. Memory B Cells are quiescent antigen-sepecific cells which differentiate following a primary immune response to a particular microbe which can become rapidly activated to differentiate into Plasma Cells if the microbe if re-encountered. B-cells can also be classified based on the subtype of antibody which they secrete ...

Isotype Control of B Cell Signaling | Science SignalingIsotype Control of B Cell Signaling | Science Signaling
The B cell receptor (BCR) consists of an antigen-binding membrane immunoglobulin (mIg) associated with the CD79α and CD79β heterodimer. Naïve B cells express the IgM and IgD isotypes, which have very short cytoplasmic tails and therefore depend on CD79α and CD79β for signal transduction. After antigenic stimulation, B cells undergo isotype switching to yield IgG, IgE, or IgA. Recent research suggests that the ability of the B cell coreceptor CD22 to regulate BCR signaling depends on the isotype of the mIg cytoplasmic tail. Cell lines that express a BCR with the cytoplasmic tail from IgG, the isotype found in memory B cells, are not subject to CD22 regulation, whereas cell lines that express BCRs with IgM cytoplasmic tails are subject to CD22 regulation. Moreover, stimulation through BCRs containing an IgG cytoplasmic tail causes increased numbers of antigen-specific clones to accumulate. These observations are a valuable step toward understanding the difference in B cell signaling between ...

As there is growing evidence for the tumor microenvironments (TME) role in tumorigenesis, we investigated the role of fibroblast-expressed kinases in triple negative breast cancer (TNBC). Using a high-throughput kinome screen combined with 3D invasion assays, we identified fibroblast-expressed PIK3Cδ (f-PIK3Cδ) as a key regulator of progression. Although PIK3Cδ was expressed in primary fibroblasts derived from TNBC patients, it was undetectable in breast cancer cell lines. Genetic and pharmacologic gain- and loss-of functions experiments verified the contribution of f-PIK3Cδ in TNBC cell invasion. Integrated secretomics and transcriptomics analyses revealed a paracrine mechanism via which f-PIK3Cδ confers its pro-tumorigenic effects. Inhibition of f-PIK3Cδ promoted the secretion of factors, including PLGF and BDNF, which led to upregulation of NR4A1 in TNBC cells where it acts as a tumor suppressor. Inhibition of PIK3Cδ in an orthotopic BC mouse model reduced tumor growth only after ...

Combination checkpoint blockade (CCB) targeting inhibitory CTLA4 and PD1 receptors holds promise for cancer therapy. Immune-related adverse events (IRAEs) remain a major obstacle for the optimal application of CCB in cancer. Here, we analyzed B cell changes in patients with melanoma following treatment with either anti-CTLA4 or anti-PD1, or in combination. CCB therapy led to changes in circulating B cells that were detectable after the first cycle of therapy and characterized by a decline in circulating B cells and an increase in CD21lo B cells and plasmablasts. PD1 expression was higher in the CD21lo B cells, and B cell receptor sequencing of these cells demonstrated greater clonality and a higher frequency of clones compared with CD21hi cells. CCB induced proliferation in the CD21lo compartment, and single-cell RNA sequencing identified B cell activation in cells with genomic profiles of CD21lo B cells in vivo. Increased clonality of circulating B cells following CCB occurred in some patients. ...

PLOS ONE: Impact of chronic and acute academic stress on lymphocyte subsets and monocyte functionPLOS ONE: Impact of chronic and acute academic stress on lymphocyte subsets and monocyte function
This study investigated the effects of a temporally confined naturalistic stressor (academic stress) on immune functions. Furthermore, moderating influences of a number of psychological variables were assessed. Five blood samples were obtained from 20 students during an observation period of 8 weeks, starting 4.5 weeks before an exam period up to 1 week following the last exam. The analysis of 45 immune parameters revealed several time-dependent changes attributable to examination stress. We observed a reduction in the absolute numbers of natural killer (NK) cells and monocytes in peripheral blood and a shift towards more immature and naïve cells within NK and T cell populations. In addition, IL-6 and TNF-α production by LPS-stimulated monocytes was increased. Psychological variables were grouped by means of factor analyses into two factors. One factor, which was interpreted as an indication of chronic stress, moderated the relationships between academic stress and percentages of mature CD57+ NK cells
