AL amyloidosis with non-amyloid forming monoclonal immunoglobulin deposition; a case mimicking AHL amyloidosis.

BMC Nephrol 2018 Nov 22;19(1):337. Epub 2018 Nov 22.

Kidney and Vascular Pathology, Faculty of Medicine, University of Tsukuba, 1-1-1 Tennodai, Tsukuba, Ibaraki, 305-8575, Japan.

Background: Immunoglobulin heavy-and-light-chain amyloidosis (AHL amyloidosis) is a newly established disease entity where both the immunoglobulin heavy-chain and light-chain compose amyloid fibrils. The immunoglobulins responsible for the amyloid fibrils are generally identified by immunostaining and/or laser microdissection-liquid chromatography-tandem mass spectrometry (LMD-LC-MS/MS). However, both techniques do not biochemically differentiate immunoglobulins that formed amyloid fibrils from non-responsible immunoglobulins. Read More

Widespread intronic polyadenylation diversifies immune cell transcriptomes.

Nat Commun 2018 04 30;9(1):1716. Epub 2018 Apr 30.

Computational and Systems Biology Program, Memorial Sloan Kettering Cancer Center, New York, NY 10065, USA.

Alternative cleavage and polyadenylation (ApA) is known to alter untranslated region (3'UTR) length but can also recognize intronic polyadenylation (IpA) signals to generate transcripts that lose part or all of the coding region. We analyzed 46 3'-seq and RNA-seq profiles from normal human tissues, primary immune cells, and multiple myeloma (MM) samples and created an atlas of 4927 high-confidence IpA events represented in these cell types. IpA isoforms are widely expressed in immune cells, differentially used during B-cell development or in different cellular environments, and can generate truncated proteins lacking C-terminal functional domains.

Heavy-Chain Diseases and Myeloma-Associated Fanconi Syndrome: an Update.

Mediterr J Hematol Infect Dis 2018 1;10(1):e2018011. Epub 2018 Jan 1.

Department of Biomedical Sciences and Human Oncology, Section of Internal Medicine, University of Bari "Aldo Moro" Medical School, Bari, Italy.

The heavy chain diseases (HCDs) are rare B-cell malignancies characterized by the production of a monoclonal immunoglobulin heavy chain without an associated light chain. There are three types of HCD, defined by the class of immunoglobulin heavy chain produced: IgA (α-HCD), IgG (γ-HCD), and IgM (μ-HCD). Alpha-HCD is the most common and usually occurs as intestinal malabsorption in a young adult from a country of the Mediterranean area. Read More

Time-course global proteome analyses reveal an inverse correlation between Aβ burden and immunoglobulin M levels in the APPNL-F mouse model of Alzheimer disease.

PLoS One 2017 23;12(8):e0182844. Epub 2017 Aug 23.

Tanz Centre for Research in Neurodegenerative Diseases, University of Toronto, Toronto, Canada.

Alzheimer disease (AD) stands out amongst highly prevalent diseases because there is no effective treatment nor can the disease be reliably diagnosed at an early stage. A hallmark of AD is the accumulation of aggregation-prone amyloid β peptides (Aβ), the main constituent of amyloid plaques. To identify Aβ-dependent changes to the global proteome we used the recently introduced APPNL-F mouse model of AD, which faithfully recapitulates the Aβ pathology of the disease, and a workflow that interrogated the brain proteome of these mice by quantitative mass spectrometry at three different ages.

Decreased WNT3 expression in chronic lymphocytic leukaemia is a hallmark of disease progression and identifies patients with worse prognosis in the subgroup with mutated IGHV.

Br J Haematol 2016 Dec 21;175(5):851-859. Epub 2016 Sep 21.

Institute of Experimental Biology, Faculty of Science, Masaryk University, Brno, Czech Republic.

The canonical Wnt pathway, dependent on β-catenin-controlled transcription, is the most explored Wnt pathway, known to drive the malignant transformation of multiple cell types. Several reports have suggested that this pathway also participates in chronic lymphocytic leukaemia (CLL) pathogenesis. To get a better insight into the role of the Wnt/β-catenin pathway in CLL we analysed in detail the expression of the most overexpressed Wnt ligand, encoded by the WNT3 gene, in a well-defined cohort of 137 CLL patients.

Department of Preventive Veterinary Medicine, College of Veterinary Medicine, Northwest A&F University, Yangling, Shaanxi 712100, China.

Porcine reproductive and respiratory syndrome (PRRS) caused by the PRRS virus (PRRSV) is an important swine disease worldwide. PRRSV has a limited tropism for certain cells, which may at least in part be attributed to the expression of the necessary cellular molecules serving as the virus receptors or factors on host cells for virus binding or entry. However, these molecules conferring PRRSV infection have not been fully characterized. Read More

Molecular Mechanisms of IgE Class Switch Recombination.

Curr Top Microbiol Immunol 2015 ;388:21-37

Department of Medicine, Division of Rheumatology, Immunology and Allergy, Brigham and Women's Hospital and Harvard Medical School, Boston, MA, 02115, USA.

Immunoglobulin (Ig) E is the most tightly regulated of all Ig heavy chain (IgH) isotypes and plays a key role in atopic disease. The gene encoding for IgH in mature B cells consists of a variable region exon-assembled from component gene segments via V(D)J recombination during early B cell development-upstream of a set of IgH constant region CH exons. Upon activation by antigen in peripheral lymphoid organs, B cells can undergo IgH class switch recombination (CSR), a process in which the initially expressed IgH μ constant region exons (Cμ) are deleted and replaced by one of several sets of downstream CH exons (e.

Implications of polyadenylation in health and disease.

Nucleus 2014 31;5(6):508-19. Epub 2014 Oct 31.

a Gene Regulation Group; IBMC-Instituto de Biologia Molecular e Celular ; Universidade do Porto ; Porto , Portugal.

Polyadenylation is the RNA processing step that completes the maturation of nearly all eukaryotic mRNAs. It is a two-step nuclear process that involves an endonucleolytic cleavage of the pre-mRNA at the 3'-end and the polymerization of a polyadenosine (polyA) tail, which is fundamental for mRNA stability, nuclear export and efficient translation during development. The core molecular machinery responsible for the definition of a polyA site includes several recognition, cleavage and polyadenylation factors that identify and act on a given polyA signal present in a pre-mRNA, usually an AAUAAA hexamer or similar sequence.

AID induces intraclonal diversity and genomic damage in CD86(+) chronic lymphocytic leukemia cells.

Eur J Immunol 2014 Dec 18;44(12):3747-57. Epub 2014 Oct 18.

Laboratory for Immunological and Molecular Cancer Research, Department of Internal Medicine III with Hematology, Medical Oncology, Hemostaseology, Infectious Diseases, Rheumatology, Oncologic Center, Paracelsus Medical University, Salzburg, Austria.

The activation-induced cytidine deaminase (AID) mediates somatic hypermutation and class switch recombination of the Ig genes by directly deaminating cytosines to uracils. As AID causes a substantial amount of off-target mutations, its activity has been associated with lymphomagenesis and clonal evolution of B-cell malignancies. Although it has been shown that AID is expressed in B-cell chronic lymphocytic leukemia (CLL), a clear analysis of in vivo AID activity in this B-cell malignancy remained elusive. Read More

The heavy chain diseases: clinical and pathologic features.

Oncology (Williston Park) 2014 Jan;28(1):45-53

Heavy chain diseases are a family of rare, systemic syndromes typically associated with or representing a variant of a B-cell neoplasm. Their characteristic feature is production of a mutated immunoglobulin heavy chain incapable of either partnering with light chains in the formation of a full immunoglobulin molecule or of being degraded by the proteasome. The abnormal heavy chain is detected in urine and/or serum without an associated light chain, a pathognomonic finding. Read More

J Neuropathol Exp Neurol 2012 Jun;71(6):520-30

Upper Airway Research Laboratory, Department of Research, Hackensack University Medical Center, Hackensack, New Jersey 07601, USA.

Dysphagia (impaired swallowing) is common in patients with Parkinson disease (PD) and is related to aspiration pneumonia, the primary cause of death in PD. Therapies that ameliorate the limb motor symptoms of PD are ineffective for dysphagia. This suggests that the pathophysiology of PD dysphagia may differ from that affecting limb muscles, but little is known about potential neuromuscular abnormalities in the swallowing muscles in PD.

Program in Cellular and Molecular Medicine and Immune Disease Institute, Children's Hospital Boston, MA 02115, USA.

Immunoglobulin heavy chain (IgH) class-switch recombination (CSR) replaces initially expressed Cμ (IgM) constant regions (C(H)) exons with downstream C(H) exons. Stimulation of B cells with anti-CD40 plus interleukin-4 induces CSR from Cμ to Cγ1 (IgG1) and Cε (IgE), the latter of which contributes to the pathogenesis of atopic diseases. Although Cε CSR can occur directly from Cμ, most mature peripheral B cells undergo CSR to Cε indirectly, namely from Cμ to Cγ1, and subsequently to Cε. Read More

NF-kappaB/STAT3/PI3K signaling crosstalk in iMyc E mu B lymphoma.

Mol Cancer 2010 Apr 30;9:97. Epub 2010 Apr 30.

University of Iowa Carver College of Medicine, Department of Pathology, Iowa City, IA, USA.

Background: Myc is a well known driver of lymphomagenesis, and Myc-activating chromosomal translocation is the recognized hallmark of Burkitt lymphoma, an aggressive form of non-Hodgkin's lymphoma. We developed a model that mimics this translocation event by inserting a mouse Myc cDNA gene into the immunoglobulin heavy chain locus, just upstream of the intronic Emu enhancer. These mice, designated iMyc E mu, readily develop B-cell lymphoma. Read More

Autosomal recessive agammaglobulinemia: novel insights from mutations in Ig-beta.

Curr Allergy Asthma Rep 2008 Sep;8(5):404-8

Clinica Pediatrica, Università di Brescia, P.le Spedali Civili 1, 25127, Brescia, Italy.

Agammaglobulinemia is a rare primary immuno-deficiency characterized by an early block of B-cell development in the bone marrow resulting in the absence of peripheral B cells and low/absent immunoglobulin serum levels. Mutations in the Bruton tyrosine kinase and in components of the pre-B-cell receptor (pre-BCR), such as mu heavy chain, surrogate light chain, and Igalpha have been found in 85% to 90% of patients affected by this disease. Here we review the recent advances in the characterization of molecular defects underlying an early block in B-cell development, focusing on the novel finding of the first two patients with agammaglobulinemia caused by mutations in Igbeta, the transmembrane protein that associates with Igalpha as part of the pre-BCR complex.

The Babraham Institute, Babraham, Cambridge CB22 3AT, United Kingdom.

Nascent, full length, immunoglobulin (Ig) heavy (H)-chains are post-translationally associated with H-chain-binding protein (BiP or GRP78) in the endoplasmic reticulum (ER). The first constant (C) domain, CH1 of a C gene (Cmu, Cgamma, Calpha), is important for this interaction. The contact is released upon BiP replacement by conventional Ig light (L)-chain (kappa or lambda). Read More

AID and RAG1 do not contribute to lymphomagenesis in Emu c-myc transgenic mice.

Oncogene 2008 Aug 14;27(34):4752-6. Epub 2008 Apr 14.

Department of Immunology, University of Toronto, Medical Sciences Building, Toronto, Canada.

DNA breaks caused by recombination-activating gene 1 (RAG1) and activation-induced cytidine deaminase (AID) induce c-myc/immunoglobulin (Ig) heavy chain chromosomal translocations and thereby stimulate lymphomagenesis. However, constitutive expression of c-myc alone is not sufficient to induce lymphomas. Because RAG1 and AID activity occurs outside of Ig genes, we assessed whether these enzymes provide the secondary genetic lesions in Emu c-myc transgenic mice to promote lymphoma development.

[Waldenström macroglobulinemia--clinical manifestations and differential diagnosis and prognosis of the disease].

Vnitr Lek 2007 Dec;53(12):1325-37

Interní hematoonkologické klinika Lékarské fakulty MU a FN Brno.

Waldenström macroglobulinemia is defined by the presence of IgM type monoclonal immunoglobulin and histological prove of lymphoplasmocytary lymphoma in the bone marrow. Clinical symptoms of the disease depend on the pressure on the bone marrow by the malignant clone with subsequent cytopenia, extramedullary infiltration and toxic manifestations of monoclonal immunoglobulin. 6q deletion and absence of translocation in the sphere of the heavy immunoglobin chain gene, which is otherwise typical for other lymphoproliferative disorders, is the typical cytogenetic abnormality.

Background: All jawed-vertebrates have four T cell receptor (TCR) chains: alpha (TRA), beta (TRB), gamma (TRG) and delta (TRD). Marsupials appear unique by having an additional TCR: mu (TRM). The evolutionary origin of TRM and its relationship to other TCR remain obscure, and is confounded by previous results that support TRM being a hybrid between a TCR and immunoglobulin locus.

Capillary immunotyping electrophoresis and high resolution two-dimensional electrophoresis for the detection of mu-heavy chain disease.

Clin Chim Acta 2008 Mar 6;389(1-2):171-3. Epub 2007 Nov 6.

2nd Department of Internal Medicine, Division of Clinical Haematology, Charles University Hospital, Hradec Králové, Czech Republic.

Heavy chain disease with monoclonal incomplete mu-heavy chains (mu-HCD) is a rare disorder usually associated with an underlying lymphoproliferative malignancy. Laboratory diagnosis of patients with mu-HCD is usually challenging and the monoclonal protein is not detected by electrophoresis in up to 75% of mu-HCD cases. We describe a patient with multiple malignancies in whom we detected and characterized monoclonal mu-heavy chains using immunofixation electrophoresis, capillary zone electrophoresis with immunotyping, and high resolution two-dimensional electrophoresis.

The identification of tumor related cell membrane protein targets is important in understanding tumor progression, the development of new diagnostic tools, and potentially for identifying new therapeutic targets. Here we present a novel strategy for identifying proteins that are altered in their expression levels in a diseased cell using cell specific aptamers. Using an intact viable B-cell Burkitt's lymphoma cell line (Ramos cells) as the target, we have selected aptamers that recognize cell membrane proteins with high affinity. Read More

Neuromuscular specializations within human pharyngeal constrictor muscles.

Ann Otol Rhinol Laryngol 2007 Aug;116(8):604-17

Department of Otolaryngology, The Mount Sinai School of Medicine, New York, NY 10029-6574, USA.

Objectives: At present it is believed that the pharyngeal constrictor (PC) muscles are innervated by the vagus (X) nerve and are homogeneous in muscle fiber content. This study tested the hypothesis that adult human PCs are divided into 2 distinct and specialized layers: a slow inner layer (SIL), innervated by the glossopharyngeal (IX) nerve, and a fast outer layer (FOL), innervated by nerve X.

Methods: Eight normal adult human pharynges (16 sides) obtained from autopsies were studied to determine 1) their gross motor innervation by use of Sihler's stain; 2) their terminal axonal branching by use of acetylcholinesterase (AChE) and silver stain; and 3) their myosin heavy chain (MHC) expression in PC muscle fibers by use of immunocytochemical and immunoblotting techniques.

Autosomal-recessive agammaglobulinemia is a rare and heterogeneous disorder, characterized by early-onset infections, profound hypogammaglobulinemia of all immunoglobulin isotypes and absence of circulating B lymphocytes. To investigate the molecular basis of the disease, 23 patients with early-onset disease and no mutations in Bruton tyrosine kinase, the gene responsible for X-linked agammaglobulinemia, were selected and analyzed by direct sequencing of candidate genes. Two novel mutations in the mu heavy chain (muHC) gene (IGHM) were identified in three patients belonging to two unrelated families. Read More

DNA Repair (Amst) 2006 Sep 11;5(9-10):1213-24. Epub 2006 Jul 11.

Laboratory of Genetics, Center for Cancer Research, National Cancer Institute, NIH, Building 37, Room 3140A, Bethesda, MD 20892-4256, USA.

Chromosomal translocations that join the cellular oncogene Myc (c-myc) with immunoglobulin (Ig) heavy-chain (Igh) or light-chain (Igk, Igl) loci are widely believed to be the crucial initiating oncogenic events in the development of B cell and plasma cell neoplasms in three mammalian species: Burkitt lymphoma (BL) in human beings, plasmacytoma (PCT) in mice, and immunocytoma in rats. Among the Myc-Ig translocations found in these neoplasms, mouse PCT T(12;15)(Igh-Myc) is of special interest because it affords a uniquely useful model system to study the fundamental outstanding questions on the mechanisms, genetics, and biological consequences of Myc translocations. Mouse T(12;15) is the direct counterpart of the human BL t(8;14)(q24;q32) translocation and thus of great relevance for human cancer. Read More

Two patterns of chromosomal breakpoint locations on the immunoglobulin heavy-chain locus in B-cell lymphomas with t(3;14)(q27;q32): relevance to histology.

The t(3;14)(q27;q32) is the most common translocation involving BCL6 in B-cell lymphoma. Although this translocation was predominantly associated with diffuse large B-cell lymphoma (DLBCL), recent studies have shown that it can also be found in follicular lymphomas (FL), often associated with a large cell component. To further investigate the relationship that might exist between this translocation and the phenotype of the tumors, we studied 34 lymphomas with a t(3;14)(q27;q32). Read More

Heavy chain diseases.

Best Pract Res Clin Haematol 2005 ;18(4):729-46

Division of General Internal Medicine, Mayo Clinic, 200 First Street SW, Rochester, MN 55905, USA.

Heavy chain diseases (HCDs) are rare B-cell lymphoplasma-cell proliferative disorders characterized by production of truncated monoclonal immunoglobulin heavy chains without associated light chains. HCDs involving the three main immunoglobulin classes have been described; alpha-HCD is the most common and has the most uniform presentation, gamma- and mu-HCDs have variable clinical presentations and histopathologic features. HCDs can be thought of as variant types of non-Hodgkin lymphoma: alpha-HCD presents as an extranodal marginal-zone lymphoma of mucosa-associated lymph-node tissue, gamma-HCD as lymphoplasmacytoid non-Hodgkin lymphoma, and mu-HCD as small lymphocytic non-Hodgkin lymphoma or chronic lymphocytic leukemia.
