Metabolic Induction of Trained Immunity through the Mevalonate Pathway.

Cell 2018 01;172(1-2):135-146.e9

Department of Internal Medicine, Radboud University Medical Center, 6525 GA Nijmegen, the Netherlands; Department for Genomics & Immunoregulation, Life and Medical Sciences Institute (LIMES), University of Bonn, 53115 Bonn, Germany. Electronic address:

Innate immune cells can develop long-term memory after stimulation by microbial products during infections or vaccinations. Here, we report that metabolic signals can induce trained immunity. Pharmacological and genetic experiments reveal that activation of the cholesterol synthesis pathway, but not the synthesis of cholesterol itself, is essential for training of myeloid cells.

Altered marginal zone and innate-like B cells in aged senescence-accelerated SAMP8 mice with defective IgG1 responses.

Cell Death Dis 2017 08 17;8(8):e3000. Epub 2017 Aug 17.

Centro Nacional de Microbiología, Instituto de Salud Carlos III (ISCIII), Majadahonda, Madrid, Spain.

Aging has a strong impact on the activity of the immune system, enhancing susceptibility to pathogens and provoking a predominant pre-inflammatory status, whereas dampening responses to vaccines in humans and mice. Here, we demonstrate a loss of marginal zone B lymphocytes (MZ, CD19CD45RCD21CD23) and a decrease of naive B cells (CD19IgD), whereas there is an enhancement of a CD19CD45R innate-like B cell population (B1REL) and the so-called aged B cell compartment (ABC, CD45RCD21CD23CD5CD11b) in aged senescence-accelerated (SAMP8) mice but not in aged senescence-resistant (SAMR1) mice. These changes in aged SAMP8 mice were associated with lower IgG isotype levels, displaying low variable gene usage repertoires of the immunoglobulin heavy chain (V) diversity, with a diminution on IgG1-memory B cells (CD11bGr1CD138IgMIgDCD19CD38IgG1), an increase in T follicular helper (T, CD4CXCR5PD1) cell numbers, and an altered MOMA-1 (metallophilic macrophages) band in primary follicles.

Metabolic Reprogramming Commits Differentiation of Human CD27IgD B Cells to Plasmablasts or CD27IgD Cells.

J Immunol 2017 07 16;199(2):425-434. Epub 2017 Jun 16.

First Department of Internal Medicine, School of Medicine, University of Occupational and Environmental Health, Japan, Kitakyushu, Fukuoka 807-8555, Japan;

B cells play a crucial role in the pathogenesis of autoimmune diseases, such as systemic lupus erythematosus (SLE). However, the relevance of the metabolic pathway in the differentiation of human B cell subsets remains unknown. In this article, we show that the combination of CpG/TLR9 and IFN-α markedly induced the differentiation of CD27IgD unswitched memory B cells into CD27CD38 plasmablasts. Read More

IgD class switching is initiated by microbiota and limited to mucosa-associated lymphoid tissue in mice.

Proc Natl Acad Sci U S A 2017 02 30;114(7):E1196-E1204. Epub 2017 Jan 30.

Center for the Genetics of Host Defense, University of Texas Southwestern Medical Center, Dallas, TX 75390;

Class-switch recombination (CSR) alters the Ig isotype to diversify antibody effector functions. IgD CSR is a rare event, and its regulation is poorly understood. We report that deficiency of 53BP1, a DNA damage-response protein, caused age-dependent overproduction of secreted IgD resulting from increased IgD CSR exclusively within B cells of mucosa-associated lymphoid tissues.

Endothelial Plasmalemma Vesicle-Associated Protein Regulates the Homeostasis of Splenic Immature B Cells and B-1 B Cells.

J Immunol 2016 11 14;197(10):3970-3981. Epub 2016 Oct 14.

Department of Microbiology and Immunology, Geisel School of Medicine at Dartmouth, Lebanon, NH 03756;

Plasmalemma vesicle-associated protein (Plvap) is an endothelial protein with roles in endothelial diaphragm formation and maintenance of basal vascular permeability. At the same time, Plvap has roles in immunity by facilitating leukocyte diapedesis at inflammatory sites and controlling peripheral lymph node morphogenesis and the entry of soluble Ags into lymph node conduits. Based on its postulated role in diapedesis, we have investigated the role of Plvap in hematopoiesis and show that deletion of Plvap results in a dramatic decrease of IgMIgD B cells in both the spleen and the peritoneal cavity.

Bacterial exploitation of phosphorylcholine mimicry suppresses inflammation to promote airway infection.

J Clin Invest 2015 Oct 31;125(10):3878-90. Epub 2015 Aug 31.

Regulation of neutrophil activity is critical for immune evasion among extracellular pathogens, yet the mechanisms by which many bacteria disrupt phagocyte function remain unclear. Here, we have shown that the respiratory pathogen Streptococcus pneumoniae disables neutrophils by exploiting molecular mimicry to degrade platelet-activating factor (PAF), a host-derived inflammatory phospholipid. Using mass spectrometry and murine upper airway infection models, we demonstrated that phosphorylcholine (ChoP) moieties that are shared by PAF and the bacterial cell wall allow S. Read More

The ataxia telangiectasia mutated and cyclin D3 proteins cooperate to help enforce TCRβ and IgH allelic exclusion.

J Immunol 2014 Sep 15;193(6):2881-90. Epub 2014 Aug 15.

Division of Cancer Pathobiology, Department of Pathology and Laboratory Medicine, Center for Childhood Cancer Research, Children's Hospital of Philadelphia, Philadelphia, PA 19104; Abramson Family Cancer Research Institute, Department of Pathology and Laboratory Medicine, Perelman School of Medicine, University of Pennsylvania, Philadelphia, PA 19104; and Immunology Graduate Group, Perelman School of Medicine, University of Pennsylvania, Philadelphia, PA 19104

Coordination of V rearrangements between loci on homologous chromosomes is critical for Ig and TCR allelic exclusion. The Ataxia Telangietasia mutated (ATM) protein kinase promotes DNA repair and activates checkpoints to suppress aberrant Ig and TCR rearrangements. In response to RAG cleavage of Igκ loci, ATM inhibits RAG expression and suppresses further Vκ-to-Jκ rearrangements to enforce Igκ allelic exclusion. Read More

Division of Microbiology and Immunology, Department of Pathology, University of Utah School of Medicine, Salt Lake City, UT 84112

The protein Zfp318 is expressed during the transition of naive B cells from an immature to mature state. To evaluate its role in mature B cell functions, a conditional gene deficiency in Zfp318 was created and deleted in bone marrow lineages via Vav-Cre. B cell development was minimally altered in the absence of the protein, although transitional 2 (T2) B cell populations were depressed in the absence of Zfp318. Read More

B cell memory to T cell-dependent (TD) Ags are considered to largely reside in class-switched CD27(+) cells. However, we previously observed that anti-RhD (D) Igs cloned from two donors, hyperimmunized with D(+) erythrocytes, were predominantly of the IgM isotype. We therefore analyzed in this study the phenotype and frequency of D- and tetanus toxoid-specific B cells by culturing B cells in limiting dilution upon irradiated CD40L-expressing EL4. Read More

B cell survival, surface BCR and BAFFR expression, CD74 metabolism, and CD8- dendritic cells require the intramembrane endopeptidase SPPL2A.

J Exp Med 2013 Jan 24;210(1):31-40. Epub 2012 Dec 24.

Ramaciotti Immunization Genomics Laboratory, John Curtin School of Medical Research, The Australian National University, Canberra, Australian Capital Territory 2600, Australia.

Druggable proteins required for B lymphocyte survival and immune responses are an emerging source of new treatments for autoimmunity and lymphoid malignancy. In this study, we show that mice with an inactivating mutation in the intramembrane protease signal peptide peptidase-like 2A (SPPL2A) unexpectedly exhibit profound humoral immunodeficiency and lack mature B cell subsets, mirroring deficiency of the cytokine B cell-activating factor (BAFF). Accumulation of Sppl2a-deficient B cells was rescued by overexpression of the BAFF-induced survival protein B cell lymphoma 2 (BCL2) but not BAFF and was distinguished by low surface BAFF receptor and IgM and IgD B cell receptors.

Mevalonate kinase genotype in children with recurrent fevers and high serum IgD level.

Rheumatol Int 2013 Dec 13;33(12):3039-42. Epub 2012 Dec 13.

Department of Pediatric Sciences, Università Cattolica Sacro Cuore, Largo A. Gemelli, 8, 00168, Rome, Italy,

In selected cases, childhood's recurrent fevers of unknown origin can be referred to systemic autoinflammatory diseases as mevalonate kinase deficiency (MKD), caused by mutations in the mevalonate kinase gene (MVK), previously named "hyper-IgD syndrome" due to its characteristic increase in serum IgD level. There is no clear evidence for studying MVK genotype in these patients. From a cohort of 305 children evaluated for recurrent fevers in our outpatient clinic during the decade 2001-2011, we have retrospectively selected 10 unrelated Italian children displaying febrile episodes, associated with recurrent inflammatory signs (variably involving gastrointestinal tube, joints, lymph nodes, and skin) and persistently increased serum IgD levels.

Hyper-IgD syndrome or mevalonate kinase deficiency.

Curr Opin Rheumatol 2011 Sep;23(5):419-23

Department of General Internal Medicine, Radboud University Nijmegen Medical Centre, Nijmegen, The Netherlands.

Purpose Of Review: The hyper-IgD and periodic fever syndrome (HIDS) is one of the classical monogenetic hereditary autoinflammatory disorders, and together with the more severe mevalonic aciduria it is also known as 'mevalonate kinase deficiency' (MKD). In this study, we will give an overview of the primary research on mevalonate kinase deficiency published in the past 2 years.

Recent Findings: Besides an inventory of a number of recent case reports, literature review shows there are several interesting developments in the basic field of research. Read More

Aberrant expression of costimulatory molecules in splenocytes of the mevalonate kinase-deficient mouse model of human hyper-IgD syndrome (HIDS).

J Inherit Metab Dis 2012 Jan 24;35(1):159-68. Epub 2011 May 24.

Department of Biological Sciences, DOW ESE Room 742, Michigan Technological University, 1400 Townsend Drive, Houghton, MI 49931, USA.

Objective: We sought to determine the activation status and proliferative capacities of splenic lymphocyte populations from a mevalonate kinase-deficient mouse model of hyper-IgD syndrome (HIDS). We previously reported that murine mevalonate kinase gene ablation was embryonic lethal for homozygous mutants while heterozygotes (Mvk (+/-)) demonstrated several phenotypic features of human HIDS including increased serum levels of IgD, IgA, and TNFα, temperature dysregulation, hematological abnormalities, and splenomegaly.

Methods And Results: Flow cytometric analysis of cell surface activation markers on T and B lymphocytes, and macrophage populations, demonstrated aberrant expression of B7 glycoproteins in all splenic cell types studied. Read More

The absence of immunoglobulin D B cell receptor-mediated signals promotes the production of autoantibodies and exacerbates glomerulonephritis in murine lupus.

Clin Exp Immunol 2011 May 24;164(2):227-35. Epub 2011 Feb 24.

Department of Pathology and Immunology, Baylor College of Medicine, Houston, TX, USA.

Immunoglobulin (Ig)D is the major antigen receptor isotype co-expressed with IgM on the surface of most peripheral B cells in mice and humans. However, the biological role of IgD as B cell receptor (BCR) has remained unclear. Previous studies have indicated that IgD may play a role in B cell tolerance. Read More

Elevated immunoglobulin D levels in children with PFAPA syndrome.

Neuro Endocrinol Lett 2010 ;31(6):743-6

2nd Department of Pediatrics, Comenius University Medical School, Slovakia.

Background: The periodic fever, aphthous stomatitis, pharyngitis and cervical adenitis (PFAPA) syndrome appears to be more common than generally appreciated and should be differentiated from hereditary periodic fever syndromes, particularly from mevalonate kinase deficiency (MKD).

Patients And Methods: 14 unrelated patients (7 males, 7 females) met clinical criteria for both the PFAPA syndrome and MKD. Immunoglobulin D (IgD) levels, mevalonic aciduria and mevalonate kinase (MVK) genotype was determined in all patients. Read More

Hyperimmunoglobulinemia D and periodic fever syndrome in children. Review on therapy with biological drugs and case report.

Acta Paediatr 2011 Jan 26;100(1):21-5. Epub 2010 Aug 26.

Pediatric Research Centre, Tampere University and University Hospital, Finland.

Unlabelled: Hyperimmunoglobulinemia D syndrome (HIDS) is a rare, autosomal recessively inherited autoinflammatory disease caused by mutations in the mevalonate kinase gene. HIDS usually starts in infancy with recurrent fever episodes lasting 3-7 days and recurring every 4-6 weeks, with only partial symptom decrease in adulthood. Fever is typically accompanied by abdominal pain, vomiting, diarrhoea and cervical lymphadenopathy, and sometimes by skin and joint symptoms. Read More

Stromal cell independent B cell development in vitro: generation and recovery of autoreactive clones.

J Immunol Methods 2010 Mar 28;354(1-2):53-67. Epub 2010 Jan 28.

Department of Immunology, DUMC 3010, Duke University Medical Center, Durham, NC 27710, USA.

We describe and characterize a stromal cell independent culture system that efficiently supports pro-B cell to IgM+ B cell development with near normal levels of IgH and Igkappa diversity. Pro-B cells present in non-adherent bone marrow cells proliferate in the presence of IL-7 and subsequent to the removal of IL-7 and addition of BAFF, differentiate normally into IgM+ B cells. B cell development in vitro closely follows the patterns of development in vivo with culture-derived (CD) B cells demonstrating characteristic patterns of surface antigen expression and gene activation.

CD20 deficiency in humans results in impaired T cell-independent antibody responses.

J Clin Invest 2010 Jan 21;120(1):214-22. Epub 2009 Dec 21.

Emma Children's Hospital, Amsterdam, The Netherlands.

CD20 was the first B cell differentiation antigen identified, and CD20-specific mAbs are commonly used for the treatment of B cell malignancies and autoantibody-mediated autoimmune diseases. Despite this the role of CD20 in human B cell physiology has remained elusive. We describe here a juvenile patient with CD20 deficiency due to a homozygous mutation in a splice junction of the CD20 gene (also known as MS4A1) that results in "cryptic" splicing and nonfunctional mRNA species.

Immunoglobulin D enhances immune surveillance by activating antimicrobial, proinflammatory and B cell-stimulating programs in basophils.

Nat Immunol 2009 Aug 28;10(8):889-98. Epub 2009 Jun 28.

Department of Pathology and Laboratory Medicine, Weill Cornell Medical College, New York, New York, USA.

Immunoglobulin D (IgD) is an enigmatic antibody isotype that mature B cells express together with IgM through alternative RNA splicing. Here we report active T cell-dependent and T cell-independent IgM-to-IgD class switching in B cells of the human upper respiratory mucosa. This process required activation-induced cytidine deaminase (AID) and generated local and circulating IgD-producing plasmablasts reactive to respiratory bacteria. Read More

Abnormal IgD and IgA1 O-glycosylation in hyperimmunoglobulinaemia D and periodic fever syndrome.

Clin Exp Med 2009 Dec 20;9(4):291-6. Epub 2009 Jun 20.

Department of General Medicine, Chase Farm Hospital, Enfield, UK.

In order to determine the glycosylation pattern for IgD, and to examine whether there are changes in the pattern of IgD and IgA1 O-glycosylation in patients with hyperimmunoglobulinaemia D and periodic fever syndrome (HIDS) during acute febrile attacks and during periods of quiescence, serum was obtained from 20 patients with HIDS and 20 control subjects. In the HIDS group, serum was obtained either during an acute febrile episode (n = 9) or during a period of quiescence (n = 11). The O-glycosylation profiles of native and desialylated IgA1 and IgD were measured in an ELISA-type system using the lectins Helix aspersa and peanut agglutinin, which bind to alternative forms of O-glycan moieties.

Functional characteristics of small proteins (70 amino acid residues) forming protein-nucleic acid complexes.

J Biomol Struct Dyn 2009 Jun;26(6):663-77

Department of Bioinformatics and Telemedicine, Collegium Medicum--Jagiellonian University, Lazarza 16, Krakow 31-530, Poland.

The proteins composed of short polypeptides (about 70 amino acid residues) participating in large complexes (ribosome) and proteins interacting with DNA/RNA were taken for analysis and classified according to the hydrophobicity excess/deficiency distribution as a measure of structural and functional specificity and similarity. The characterization of this group of proteins is the introductory part to the analysis of the so called "Never Born Proteins" (NBP) in search for protein compounds exhibiting biological activity that may be valuable in pharmacological research. The entropy scale (classification between random and deterministic limits) organized in ranking list allows the comparative analysis of the proteins under consideration. Read More
