Agammaglobulinemia
An immunologic deficiency state characterized by an extremely low level of generally all classes of gamma-globulin in the blood.
Genetic Diseases, X-Linked
Genetic diseases that are linked to gene mutations on the X CHROMOSOME in humans (X CHROMOSOME, HUMAN) or the X CHROMOSOME in other species. Included here are animal models of human X-linked diseases.
X Chromosome
The female sex chromosome, being the differential sex chromosome carried by half the male gametes and all female gametes in human and other male-heterogametic species.
Protein-Tyrosine Kinases
Protein kinases that catalyze the PHOSPHORYLATION of TYROSINE residues in proteins with ATP or other nucleotides as phosphate donors.
B-Lymphocytes
Lymphoid cells concerned with humoral immunity. They are short-lived cells resembling bursa-derived lymphocytes of birds in their production of immunoglobulin upon appropriate stimulation.
Genetic Linkage
The co-inheritance of two or more non-allelic GENES due to their being located more or less closely on the same CHROMOSOME.
Immunologic Deficiency Syndromes
Syndromes in which there is a deficiency or defect in the mechanisms of immunity, either cellular or humoral.
Immunoglobulin delta-Chains
The class of heavy chains found in IMMUNOGLOBULIN D. They have a molecular weight of approximately 64 kDa and they contain about 500 amino acid residues arranged in four domains and an oligosaccharide component covalently bound to the Fc fragment constant region.
IgG Deficiency
A dysgammaglobulinemia characterized by a deficiency of IMMUNOGLOBULIN G.
Ecthyma
An ulcerative pyoderma usually caused by group A beta-hemolytic streptococcal infection at the site of minor trauma. (Dorland, 27th ed)
Campylobacter lari
A species of thermophilic CAMPYLOBACTER found in healthy seagulls and causing ENTERITIS in humans.
Receptors, Antigen, B-Cell
IMMUNOGLOBULINS on the surface of B-LYMPHOCYTES. Their MESSENGER RNA contains an EXON with a membrane spanning sequence, producing immunoglobulins in the form of type I transmembrane proteins as opposed to secreted immunoglobulins (ANTIBODIES) which do not contain the membrane spanning segment.
Helicobacter
A genus of gram-negative, spiral-shaped bacteria that has been isolated from the intestinal tract of mammals, including humans. It has been associated with PEPTIC ULCER.
Immunoglobulins, Intravenous
Immunoglobulin preparations used in intravenous infusion, containing primarily IMMUNOGLOBULIN G. They are used to treat a variety of diseases associated with decreased or abnormal immunoglobulin levels including pediatric AIDS; primary HYPERGAMMAGLOBULINEMIA; SCID; CYTOMEGALOVIRUS infections in transplant recipients, LYMPHOCYTIC LEUKEMIA, CHRONIC; Kawasaki syndrome, infection in neonates, and IDIOPATHIC THROMBOCYTOPENIC PURPURA.

The human female sex chromosome, being the differential sex chromosome carried by half the male gametes and all female gametes in humans.
Dosage Compensation, Genetic
Genetic mechanisms that allow GENES to be expressed at a similar level irrespective of their GENE DOSAGE. This term is usually used in discussing genes that lie on the SEX CHROMOSOMES. Because the sex chromosomes are only partially homologous, there is a different copy number, i.e., dosage, of these genes in males vs. females. In DROSOPHILA, dosage compensation is accomplished by hypertranscription of genes located on the X CHROMOSOME. In mammals, dosage compensation of X chromosome genes is accomplished by random X CHROMOSOME INACTIVATION of one of the two X chromosomes in the female.

Immunoglobulin M
A class of immunoglobulin bearing mu chains (IMMUNOGLOBULIN MU-CHAINS). IgM can fix COMPLEMENT. The name comes from its high molecular weight and originally being called a macroglobulin.
Immunoglobulins
Multi-subunit proteins which function in IMMUNITY. They are produced by B LYMPHOCYTES from the IMMUNOGLOBULIN GENES. They are comprised of two heavy (IMMUNOGLOBULIN HEAVY CHAINS) and two light chains (IMMUNOGLOBULIN LIGHT CHAINS) with additional ancillary polypeptide chains depending on their isoforms. The variety of isoforms include monomeric or polymeric forms, and transmembrane forms (B-CELL ANTIGEN RECEPTORS) or secreted forms (ANTIBODIES). They are divided by the amino acid sequence of their heavy chains into five classes (IMMUNOGLOBULIN A; IMMUNOGLOBULIN D; IMMUNOGLOBULIN E; IMMUNOGLOBULIN G; IMMUNOGLOBULIN M) and various subclasses.
Lymphocyte Count
The number of LYMPHOCYTES per unit volume of BLOOD.

Identification of a subpopulation of lymphocytes in human peripheral blood cytotoxic to autologous fibroblasts. (1/604)

A naturally occurring subpopulation of human peripheral blood lymphocytes is cytotoxic to autologous and/or allogeneic fibroblasts. The autocytotoxic lymphocytes have a receptor for the third component of complement and for aggregated gamma globulin, do not form rosettes with sheep red blood cells, and are not removed by passage through nylon. The autocytotoxic subpopulation is not present in the thymus and tonsils of normal children or in the peripheral blood of individuals with X-linked agammaglobulinemia. Fibroblast absorption experiments demonstrate that the autocytotoxic cells are "sensitized" to antigens expressed on allogeneic fibroblasts in addition to the antigens expressed on autologous cells. Some normal individuals have a second subpopulation of lymphocytes that may "regulate" the autocytotoxic cells. The relevance of these observations to the murine autocytotoxic cells is discussed.  (+info)

Induction of human immunoglobulin synthesis and secretion in somatic cell hybrids of mouse myeloma and human B lymphocytes from patients with agammaglobulinemia. (2/604)

Somatic cell hybrid clones were isolated from the fusion of RPC 5,4 mouse myeloma cells and B lymphocytes from three patients with agammaglobulinemia. One patient had X-linked agammaglobulinemia; the remaining two patients had common varied agammaglobulinemia. All three patients had B lymphocytes which fail to secrete immunoglobulin. The hybrid nature of the clones was established by examination of metaphase chromosome spreads. Most of the clones from all three patients expressed surface immunoglobulin of mouse and human parental origin. Clones from two of the patients had fewer cells with surface Ig than hybrids from normal persons, while clones from the third patient had large numbers of surface Ig fluorescent cells. Most of the clones from all three patients synthesized and secreted human and mouse immunoglobulin. As determined by sodium dodecyl sulfate acrylamide gel electrophoresis of radioactively labeled proteins, clones from each of the patients produced human gamma, alpha, and mu-heavy chains. These studies demonstrate the presence of functional structural genes coding for human immunoglobulin heavy chains in B lymphocytes of patients with agammaglobulinemia. Further, they represent induction in the somatic cell hybrids of a gene product not expressed in the parental B lymphocytes.  (+info)

Functions of Bruton's tyrosine kinase in mast and B cells. (3/604)

Bruton's tyrosine kinase (Btk) plays crucial roles in B cell differentiation as well as mast cell activation through the high-affinity IgE receptor (FcepsilonRI). Defects in the btk gene lead to agammaglobulinemia (XLA) in humans and X-linked immunodeficiency (xid) in mice. Mast cells from xid and btk null mice exhibit mild defects in degranulation and severe impairments in the production of proinflammatory cytokines upon FcepsilonRI cross-linking. Recent studies demonstrated the role of Btk in a sustained increase in intracellular calcium concentrations in response to antigen receptor stimulation. Btk is also involved in the activation of stress-activated protein kinases, JNK/SAPK1/2, and thereby regulates c-Jun and other transcription factors that are important in cytokine gene activation. Regulation of the JNK/SAPK activation pathway by Btk may be related to the proapoptotic function of Btk in the programmed cell death in these hematopoietic cells.  (+info)

Comparative genomics and host resistance against infectious diseases. (4/604)

The large size and complexity of the human genome have limited the identification and functional characterization of components of the innate immune system that play a critical role in front-line defense against invading microorganisms. However, advances in genome analysis (including the development of comprehensive sets of informative genetic markers, improved physical mapping methods, and novel techniques for transcript identification) have reduced the obstacles to discovery of novel host resistance genes. Study of the genomic organization and content of widely divergent vertebrate species has shown a remarkable degree of evolutionary conservation and enables meaningful cross-species comparison and analysis of newly discovered genes. Application of comparative genomics to host resistance will rapidly expand our understanding of human immune defense by facilitating the translation of knowledge acquired through the study of model organisms. We review the rationale and resources for comparative genomic analysis and describe three examples of host resistance genes successfully identified by this approach.  (+info)

IgM heavy chain complementarity-determining region 3 diversity is constrained by genetic and somatic mechanisms until two months after birth. (5/604)

Due to the greater range of lengths available to the third complementarity determining region of the heavy chain (HCDR3), the Ab repertoire of normal adults includes larger Ag binding site structures than those seen in first and second trimester fetal tissues. Transition to a steady state range of HCDR3 lengths is not complete until the infant reaches 2 mo of age. Fetal constraints on length begin with a genetic predilection for use of short DH (D7-27 or DQ52) gene segments and against use of long DH (e.g., D3 or DXP) and JH (JH6) gene segments in both fetal liver and fetal bone marrow. Further control of length is achieved through DH-specific limitations in N addition, with D7-27 DJ joins including extensive N addition and D3-containing DJ joins showing a paucity of N addition. DH-specific constraints on N addition are no longer apparent in adult bone marrow. Superimposed upon these genetic mechanisms to control length is a process of somatic selection that appears to ensure expression of a restricted range of HCDR3 lengths in both fetus and adult. B cells that express Abs of an "inappropriate" length appear to be eliminated when they first display IgM on their cell surface. Control of N addition appears aberrant in X-linked agammaglobulinemia, which may exacerbate the block in B cell development seen in this disease. Restriction of the fetal repertoire appears to be an active process, forcing limits on the diversity, and hence range of Ab specificities, available to the young.  (+info)

Early arrest in B cell development in transgenic mice that express the E41K Bruton's tyrosine kinase mutant under the control of the CD19 promoter region. (6/604)

Bruton's tyrosine kinase (Btk) is a nonreceptor protein kinase that is defective in X-linked agammaglobulinemia in humans and in X-linked immunodeficiency in mice. To study the effect of Btk activation in early B cell development in vivo, we have created transgenic mouse strains expressing Btk under the control of the human CD19 promoter region. The transgenic expression of wild-type human Btk corrected all X-linked immunodeficiency features in mice carrying a targeted disruption of the Btk gene. In contrast, expression of an activated form of Btk, the E41K mutant, resulted in an almost complete arrest of B cell development in the immature IgM+IgD- B cell stage in the bone marrow, irrespective of the presence of the endogenous intact Btk gene. Immature B cells were arrested at the progression from IgMlow into IgMhigh cells, which reflects the first immune tolerance checkpoint at which autoreactive B cells become susceptible to apoptosis. As the constitutive activation of Btk is likely to mimic B cell receptor occupancy by autoantigens in the bone marrow, our findings are consistent with a role for Btk as a mediator of B cell receptor-induced apoptotic signals in the immature B cell stage. Whereas the peripheral mature B cell pool was reduced to <1% of the normal size, significant numbers of IgM-secreting plasma cells were present in the spleen. Serum IgM levels were substantial and increased with age, but specific Ab responses in vivo were lacking. We conclude that the residual peripheral B cells were efficiently driven into IgM+ plasma cell differentiation, apparently without functional selection.  (+info)

In vivo modulation of cytokine synthesis by intravenous immunoglobulin. (7/604)

We examined the effects of intravenous immunoglobulin (IVIG) on cytokine regulation in vivo using samples taken before and after replacement-dose (200-400 mg/kg) IVIG in a group of patients with common variable immunodeficiency (CVID) and X-linked agammaglobulinaemia (XLA). The intracellular cytokine content of CD4+ and CD8+ lymphocytes, and their CD28+/- subsets, were measured following in vitro activation with phorbol myristate acetate (PMA) and ionomycin. The cytokines IL-2, interferon-gamma (IFN-gamma) and tumour necrosis factor-alpha (TNF-alpha), and the early activation marker CD69, were assessed by four-colour flow cytometry of whole blood cultures taken before and after IVIG infusion. There was a significant increase in IL-2 expression in CD4+ (and CD4+28-) cells and an increase in TNF-alpha expression in CD8+28- cells following IVIG in CVID, but not in XLA patients. IFN-gamma and CD69 expression were not affected by IVIG infusion. This increase in TNF-alpha and IL-2, combined with unchanged IFN-gamma expression, is evidence against the putative 'anti-inflammatory' role of IVIG, and may explain the failure of resolution of granulomata in CVID patients treated with IVIG alone.  (+info)

CD95 expression and function on lymphocyte subpopulations in common variable immunodeficiency (CVID); related to increased apoptosis. (8/604)

Apoptosis is now recognized as a central process of development and disease, and it has been proposed as one of the mechanisms that may account for the lymphopenia seen in some diseases. In this study we measured spontaneous apoptosis and CD95 expression on different cell subpopulations from CVID patients, using flow cytometric techniques. We divided our patients into two groups according to their CD4+ and CD4+CD45RA+ cell counts. Our results clearly show increased spontaneous apoptosis and CD95 expression on the CD4+ and CD4+CD45RA+ subsets from lymphopenic CVID patients compared with normal subjects and disease controls. Interestingly, our lymphopenic CVID patients presented a profound reduction in absolute counts, mainly affecting the CD4+CD45RA+ subpopulation. We also found a statistically significant direct correlation between absolute numbers of CD4+CD45RA+ T cells and spontaneous apoptosis on the same subset in CVID patients, but attempts to induce CD95-mediated apoptosis were unsuccessful despite increased CD95 expression on CD4+ T cells. These findings suggest that apoptosis could be one of the mechanisms implicated in the significant lymphopenia present in these patients.  (+info)

X-Linked Agammaglobulinemia - DiplomatX-Linked Agammaglobulinemia - Diplomat
X-linked agammaglobulinemia, also known as Bruton agammaglobulinemia, is caused by a mutation in a gene found in the X chromosome. This mutation affects the ability of the body to fight infections. Because it is an X-linked mutation, XLA mostly affects boys.. Symptoms often start around six months in age. As protective antibodies from the infants mother wear off, patients with XLA are unable to produce enough B cells, compromising the bodys ability to fight infection. In rare cases, symptoms might not occur until the patient is a teenager.. XLA is extremely rare, occurring in only one in 200,000 newborns. Children with XLA might cope well with short-term viral infections but are susceptible to chronic viral infections such as hepatitis and polio. Common bacterial infections in XLA patients include ear infections, pink eye, pneumonia, sinus infections and other infections causing diarrhea.. Regular immune globulin treatment can offer XLA patients the antibodies crucial to their health.. ...

X-linked agammaglobulinemia - WikipediaX-linked agammaglobulinemia - Wikipedia
X-linked agammaglobulinemia (XLA) is a rare genetic disorder discovered in 1952 that affects the bodys ability to fight infection. As the form of agammaglobulinemia that is X-linked, it is much more common in males. In people with XLA, the white blood cell formation process does not generate mature B cells, which manifests as a complete or near-complete lack of proteins called gamma globulins, including antibodies, in their bloodstream. B cells are part of the immune system and normally manufacture antibodies (also called immunoglobulins), which defend the body from infections by sustaining a humoral immunity response. Patients with untreated XLA are prone to develop serious and even fatal infections. A mutation occurs at the Brutons tyrosine kinase (Btk) gene that leads to a severe block in B cell development (at the pre-B cell to immature B cell stage) and a reduced immunoglobulin production in the serum. Btk is particularly responsible for mediating B cell development and maturation through ...

article{f99aaa99-0083-4fd0-acad-1c035bd066a7, abstract = {It has been suggested that tryptophan 563 is sandwiched between residues R562 and A532 in Brutons agammaglobulinemia tyrosine kinase (Btk). Mutations of the surrounding residues have been shown to cause X-linked agammaglobulinemia. Substitutions R562P and A582V were noticed to have impaired kinase activity. However, based on Western blot analysis, the mutant proteins were expressed at normal levels. Molecular modeling of the kinase domain has previously indicated that these residues presumably govern the position of the W563 side chain, which is thought to interact with the catalytic loop. W563 is inside the molecule and too far away from the catalytic center to interact directly with the substrate or cofactors. To prove these model-based conclusions, a conservative substitution with phenylalanine for W563 was made, and the resultant mutant lacked kinase activity. These results confirm our previous assumption that the side chain of W563, ...

Intestinal absorption was investigated in six patients with a diagnosis of primary hypogammaglobulinemia. Malabsorption was found in four patients. Low serum vitamin E levels, decreased D-xylose absorption, and increased 5-hydroxyindoleacetic acid excretion in the urine correlated with malabsorption with minor exceptions. Five patients were subjected to jejunal biopsies, and nodular lymphoid hyperplasia was found on at least one examination in each of these patients. In addition, partial to complete mucosal atrophy characterized biopsy specimens from four patients and correlated with steatorrhea with one exception. Although gastric achlorhydria (two patients), minimal to moderate pancreatic insufficiency (two patients), significant intestinal intraluminal bacterial overgrowth (three patients), and Giardia lamblia (five patients) were found, the evidence suggests that the most significant cause of malabsorption in these hypogammaglobulinemic patients is an intestinal mucosal lesion.

A recurrent dominant negative E47 mutation causes agammaglobulinemia and BCR(-) B cells | Garvan Institute of Medical ResearchA recurrent dominant negative E47 mutation causes agammaglobulinemia and BCR(-) B cells | Garvan Institute of Medical Research
Approximately 90% of patients with isolated agammaglobulinemia and failure of B cell development have mutations in genes required for signaling through the pre-B cell and B cell receptors. The nature of the gene defect in the majority of remaining patients is unknown. We recently identified 4 patients with agammaglobulinemia and markedly decreased numbers of peripheral B cells. The B cells that could be detected had an unusual phenotype characterized by the increased expression of CD19 but the absence of a B cell receptor. Genetic studies demonstrated that all 4 patients had the exact same de novo mutation in the broadly expressed transcription factor E47. The mutant protein (E555K) was stable in patient-derived EBV-transformed cell lines and cell lines transfected with expression vectors. E555K in the transfected cells localized normally to the nucleus and resulted in a dominant negative effect when bound to DNA as a homodimer with wild-type E47. Mutant E47 did permit DNA binding by a tissue-specific

SUMMARY. An 18-year-old white man with congenital agammaglobulinemia that was probably sex-linked developed clinically and pathologically typical regional enteritis. The association of these diseases provides evidence that antibody is not directly involved in the pathogenesis of regional enteritis and that plasma cells, a usual histologic feature of regional enteritis, are not essential. Antibody lack probably does not predispose to regional enteritis, and cellular immunity may be important in its pathogenesis. ...

BTKFP : X-linked agammaglobulinemia (XLA) is a humoral primary immunodeficiency affecting males in approximately 1 in 200,000 live births. XLA is caused by variants in the Bruton tyrosine kinase gene (BTK),(1) which results in a profound block in B-cell development within the bone marrow and a significant reduction, or complete absence, of mature B cells in peripheral blood.(2) Approximately 85% of male patients with defects in early B-cell development have XLA.(3) Due to the lack of mature B cells, XLA patients have markedly reduced levels of all major classes of immunoglobulins in the serum and are, therefore, susceptible to severe and recurrent bacterial infections. Pneumonia, otitis media, enteritis, and recurrent sinopulmonary infections are among the key clinical diagnostic characteristics of the disease. The spectrum of infectious complications also includes enteroviral meningitis, septic arthritis, cellulitis, and empyema, among others. The disease typically manifests in male children younger

Results Rheumatological manifestations were seen in 27.4% patients of XLA. Thirteen out of 17 patients had a proven mutation in Btk gene. Mean age at symptom onset was 3.3 years (range 6 months - 13 years) and mean age at diagnosis of XLA was 5.6 years (range 1.5- 10 years). Rheumatological manifestations were seen at a mean age of 8.7 years (range 1.5- 20 years). In 2 patients, arthritis preceded the diagnosis of XLA while 10 patients developed rheumatological manifestations after the diagnosis of XLA. Arthritis as an initial presentation of XLA was seen in 5 patients.. Oligoarthritis was the most common presentation seen in 15 patients. Knee was the most commonly involved joint (11 patients) followed by ankle joint in 5 patients and shoulder, wrist and hip arthritis in 2 patients each.

Report shows significant improvement in survival rates for patients with X-linked agammaglobulinemia

In the past, the majority of patients with XLA died of acute or chronic infections in the first two decades of life, Howard noted. But in the last 20 years the outlook for patients with XLA has significantly improved, thanks to earlier diagnosis and improved gamma globulin therapy. Our study is reassuring and helps to put into perspective the ability of such patients to thrive with proper care, despite this potentially devastating disease ...

ASMscience | Primary Antibody Deficie
In recent years several rare autosomal recessive disorders that result in antibody deficiency have been reported. Some antibody deficiencies are part of a more broadly expressed systemic disorder or part of an immunodeficiency that affects T cells and/or NK cells as well as B cells. The possibility of immunodeficiency should be considered in any patient who is hospitalized for a major infection requiring intravenous therapy. Most patients with X-linked agammaglobulinemia (XLA) develop recurrent or persistent infections in the first 4 to 8 months of life, and the majority are recognized to have immunodeficiency at less than 3 years of age. Defects in μ heavy chain account for about one-third of the patients with autosomal recessive agammaglobulinemia. Mutation detection is the most practical way of making a definitive diagnosis. Single gene defects of the immune system may have features in common with common variable immunodeficiency (CVID). Recent studies suggest that analysis of B-cell phenotype may

Bacterial lipopolysaccharides (LPS) derived from a variety of organisms effectively induced C consumption in humans, bovines, and porcines with developmental agammaglobulinemia; birds with experimental agammaglobulinemia; and humans with agammaglobulinemia syndromes. This interaction proceeded even in precolostral piglet sera which contained less than 2.5 x 10-6 mg/ml gamma globulin, and led to generation of neutrophil chemotactic factor and anaphylatoxin in these sera. Hence, the LPS-C interaction can proceed in sera markedly deficient in immunoglobulin. The question of whether immunoglobulins can be bypassed in the LPS-C interaction, or whether they are regularly utilized in a way so efficient that their participation is masked, was considered. ...

Role of Brutons tyrosine kinase in B cells and malignancies - ScienceOpenRole of Brutons tyrosine kinase in B cells and malignancies - ScienceOpen
Brutons tyrosine kinase (BTK) is a non-receptor kinase that plays a crucial role in oncogenic signaling that is critical for proliferation and survival of leukemic cells in many B cell malignancies. BTK was initially shown to be defective in the primary immunodeficiency X-linked agammaglobulinemia (XLA) and is essential both for B cell development and function of mature B cells. Shortly after its discovery, BTK was placed in the signal transduction pathway downstream of the B cell antigen receptor (BCR). More recently, small-molecule inhibitors of this kinase have shown excellent anti-tumor activity, first in animal models and subsequently in clinical studies. In particular, the orally administered irreversible BTK inhibitor ibrutinib is associated with high response rates in patients with relapsed/refractory chronic lymphocytic leukemia (CLL) and mantle-cell lymphoma (MCL), including patients with high-risk genetic lesions. Because ibrutinib is generally well tolerated and shows durable ...

Brutons Tyrosine Kinase Revealed as a Negative Regulator of Wnt-β-Catenin Signaling | Science SignalingBrutons Tyrosine Kinase Revealed as a Negative Regulator of Wnt-β-Catenin Signaling | Science Signaling
Wnts are secreted ligands that activate several receptor-mediated signal transduction cascades. Homeostatic Wnt signaling through β-catenin is required in adults, because either elevation or attenuation of β-catenin function has been linked to diverse diseases. To contribute to the identification of both protein and pharmacological regulators of this pathway, we describe a combinatorial screen that merged data from a high-throughput screen of known bioactive compounds with an independent focused small interfering RNA screen. Each screen independently revealed Brutons tyrosine kinase (BTK) as an inhibitor of Wnt-β-catenin signaling. Loss of BTK function in human colorectal cancer cells, human B cells, zebrafish embryos, and cells derived from X-linked agammaglobulinemia patients with a mutant BTK gene resulted in elevated Wnt-β-catenin signaling, confirming that BTK acts as a negative regulator of this pathway. From affinity purification-mass spectrometry and biochemical binding studies, we ...

Chronic lymphocytic leukemia (CLL) is a common adult leukemia that is currently incurable outside of stem cell transplantation. Although response to IgM ligation is variable, the B-cell receptor (BCR) signaling pathway is aberrantly active in this disease, with antigen-dependent1,2 or -independent autonomous activation,3 leading to constitutive activation of kinases inducing cell survival and proliferation.4⇓⇓-7 One BCR pathway kinase that is uniformly overexpressed at the transcript level8 and constitutively phosphorylated in CLL is Brutons tyrosine kinase (BTK). Ibrutinib, an orally bioavailable irreversible inhibitor of BTK, has recently been shown to have outstanding clinical activity in CLL with extended durable remissions in both untreated and relapsed disease.9. BTK is a critical mediator of B-lymphocyte signaling and development. Mutations in various domains are responsible for X-linked agammaglobulinemia,10,11 a disorder characterized by developmental arrest of B cells and profound ...

infection (Wintrobe & Hasenbush, 1939) and we now know that most patients will develop low levels of immunoglobulin if cases are followed for long enough. Hypogammaglobulinaemia was first recognized as a clinical entity by Bruton (1952), when electrophoresis of serum revealed the surprising absence of the gamma fraction in an otherwise normal pattern. Immunological studies showed a complete absence of antibodies and isohaemagglutinins. Odd case reports of agammaglobulinaemia in CLL began appearing shortly afterwards (Brem & Morton, 1955; Jim & Reinhard, 1956). Jim (1957) found that 17 out of 50 patients had hypogammaglobulinaemia. In a more comprehensive study, Cone & Uhr (1964) found deficiencies in all classes of serum immunoglobulins and failure to produce an antibody response to phi x 174, a primary antigen, or diphtheria toxoid, a secondary antigen. There was also a failure to sensitize to dinitrofluorobenzene, although most patients did produce a delayed hypersensitivity response to recall ...

Tirabrutinib HCl, also known as ONO-4059 HCl, is a potent and orally active Bruton agammaglobulinemia tyrosine kinase (BTK) in hibitor. Upon administration, ONO-4059 covalently binds to BTK within B cells, thereby preventing B-cell receptor signaling and impeding B-cell development. As a result, this agent may inhibit the proliferation of B-cell malignancies. BTK, a cytoplasmic tyrosine kinase and member of the Tec family of kinases, plays an important role in B lymphocyte development, activation, signaling, proliferation and survival.

JCI - Genes required for B cell developmentJCI - Genes required for B cell development
Based on the observation that there were no abnormalities in the other allele of LRRC8, and that protein from the normal and abnormal alleles were expressed in white blood cells from the patient, the authors interpret their results as indicating that the mutation had a dominant-suppressor effect on B cell development (24). It is interesting to speculate on how this dominant effect might occur and whether there might be other patients with agammaglobulinemia due to similar mutations. Several mechanisms can explain an autosomal dominant effect. For example, if the last two leucine-rich domains function as self-inhibitory domains, the loss of those domains might result in a constitutively active protein; or, if the protein is part of a multimeric complex that includes more than one copy of the LRRC8 protein, one abnormal allele could alter the function of a majority of complexes. Occasionally, an abnormal protein can change the stability or location of a binding partner and thereby inhibit the ...

However the backbone of most immunomodulatory regimens includes glucocorticoids, the consequences of glucocorticoids on polysaccharide responses are known insufficiently. This causes further problems in differentiating major and supplementary antibody deficiencies from one another 2.

Monitoring of Immunoglobulin Levels Identifies Kidney Transplant Recipients at High Risk of Infection | Transplant Now
Infections post-transplant are common, but it is difficult to predict which patients are most at risk. Hypogammaglobulinemia is a known risk factor for infection. In this prospective, single-center observational study, low immunoglobulin levels were common post-transplant, and correlated with an increased risk of infection. This study raises the question of whether such monitoring should become routine practice, and whether giving immunoglobulin replacement to patients with demonstrated low levels would reduce infection rates.. ...

Solute concentrations ranging between 1 and 10 mg/ml were measured at 10°C. 15 successive 60 second frames were collected. The data were normalized to the intensity of the transmitted beam and radially averaged; the scattering of the solvent-blank was subtracted and the different curves were scaled for protein concentration. The low angle data collected at lower concentration were merged with the highest concentration high angle data to yield the final composite scattering curve.
