Genetic loss of NFAT2 (NFATc1) impairs B cell development of B1 and B2 B cells.

Cell Immunol 2020 03 28;349:104048. Epub 2020 Jan 28.

Dept. of Hematology, Oncology and Immunology, University Hospital Tübingen, Tübingen, Germany; Dept. of Hematology, Oncology and Immunology, Klinikum Region Hannover, KRH Klinikum Siloah, Hannover, Germany. Electronic address:

NFAT2 activity was shown to be of critical importance in B cell receptor signaling, development and proliferation; however its role in B cell development in the periphery is still not completely understood. We confirmed that NFAT2 deletion leads to impaired B1 B cell development, supported by our finding of limited B1 progenitors in the bone marrow and spleen of NFAT2 deficient mice. Moreover, we show for the first time that loss of NFAT2 increases immature B cells in particular transitional T2 and T3 as well as mature follicular B cells while marginal zone B cells are decreased.

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

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

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

The majority of human memory B cells recognizing RhD and tetanus resides in IgM+ B cells.

J Immunol 2014 Aug 25;193(3):1071-9. Epub 2014 Jun 25.

Department of Experimental Immunohematology, Sanquin Research and Landsteiner Laboratory, Academic Medical Center, University of Amsterdam, 1066 CX Amsterdam, the Netherlands; and

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
