Front Pediatr 2018 4;6:130. Epub 2018 May 4.

Department of Immunology, Institute of Biomedical Sciences, University of São Paulo, São Paulo, Brazil.

Mutations in the CD40 ligand (CD40L) gene () lead to X-linked hyper-IgM syndrome (X-HIGM), which is a primary immunodeficiency (PID) characterized by decreased serum levels of IgG and IgA and normal or elevated IgM levels. Although most X-HIGM patients become symptomatic during the first or second year of life, during which they exhibit recurrent infections, some patients exhibit mild phenotypes, which are usually associated with hypomorphic mutations that do not abrogate protein expression or function. Here, we describe a 28-year-old man who initially presented with recurrent infections since the age of 7 years, when he exhibited meningitis caused by . Read More

Regulation of Hematopoietic Cell Development and Function Through Phosphoinositides.

Front Immunol 2018 4;9:931. Epub 2018 May 4.

Department of Immunology and Microbiology, The Scripps Research Institute, La Jolla, CA, United States.

One of the most paramount receptor-induced signal transduction mechanisms in hematopoietic cells is production of the lipid second messenger phosphatidylinositol(3,4,5)trisphosphate (PIP) by class I phosphoinositide 3 kinases (PI3K). Defective PIP signaling impairs almost every aspect of hematopoiesis, including T cell development and function. Limiting PIP signaling is particularly important, because excessive PIP function in lymphocytes can transform them and cause blood cancers. Read More

Methods: In the predominantly European study population of principally sporadic unrelated PID cases (n = 846), a novel Bayesian method identified nuclear factor κB subunit 1 (NFKB1) as one of the genes most strongly associated with PID, and the association was explained by 16 novel heterozygous truncating, missense, and gene deletion variants.

Low Serum IgE Is a Sensitive and Specific Marker for Common Variable Immunodeficiency (CVID).

J Clin Immunol 2018 Apr 17;38(3):225-233. Epub 2018 Feb 17.

Department of Medicine, University of Virginia, Box 801355, Charlottesville, VA, 22908, USA.

Although small prior studies have suggested that IgE can be low in common variable immunodeficiency (CVID), the workup for patients with recurrent infections and suspected hypogammaglobulinemia does not include the routine measurement of serum IgE. We sought to test the hypothesis that low/undetectable serum IgE is characteristic of CVID by comparing the frequency of low/undetectable serum IgE in healthy controls and patients with CVID. We measured total serum IgE in a large multi-center cohort of patients with CVID (n = 354) and compared this to large population-based cohorts of children and adults. Read More

Clinical Implications of Digenic Inheritance and Epistasis in Primary Immunodeficiency Disorders.

Front Immunol 2017 26;8:1965. Epub 2018 Jan 26.

School of Biological Sciences, University of Auckland, Auckland, New Zealand.

The existence of epistasis in humans was first predicted by Bateson in 1909. Epistasis describes the non-linear, synergistic interaction of two or more genetic loci, which can substantially modify disease severity or result in entirely new phenotypes. The concept has remained controversial in human genetics because of the lack of well-characterized examples. Read More

Proline-serine-threonine phosphatase interacting protein 1 (PSTPIP1) controls immune synapse stability in human T cells.

J Allergy Clin Immunol 2018 Feb 9. Epub 2018 Feb 9.

Department of Pediatric Immunology and Laboratory of Translational Immunology, Wilhelmina Children's Hospital, University Medical Center Utrecht, Utrecht, The Netherlands. Electronic address:

Background: Proline-serine-threonine phosphatase interacting protein 1 (PSTPIP1) is a cytosolic adaptor protein involved with T-cell activation, differentiation, and migration. On cognate T-cell contact, PSTPIP1 is recruited to surface-expressed CD2, where it regulates F-actin remodeling. An immune synapse (IS) is thereby rapidly formed, consisting of T-cell receptor clusters surrounded by a ring of adhesion molecules, including CD2. Read More

Human NF-κB1 Haploinsufficiency and Epstein-Barr Virus-Induced Disease-Molecular Mechanisms and Consequences.

Front Immunol 2017 18;8:1978. Epub 2018 Jan 18.

Ludwig Boltzmann Institute for Rare and Undiagnosed Diseases, Vienna, Austria.

Nuclear factor kappa-light-chain-enhancer of activated B cells 1 (NF-κB1)-related human primary immune deficiencies have initially been characterized as defining a subgroup of common variable immunodeficiencies (CVIDs), representing intrinsic B-cell disorders with antibody deficiency and recurrent infections of various kind. Recent evidence indicates that NF-κB1 haploinsufficiency underlies a variable type of combined immunodeficiency (CID) affecting both B and T lymphocyte compartments, with a broadened spectrum of disease manifestations, including Epstein-Barr virus (EBV)-induced lymphoproliferative disease and immediate life-threatening consequences. As part of this review series focused on EBV-related primary immunodeficiencies, we discuss the current clinical and molecular understanding of monoallelic germline mutations with special focus on the emerging context of EBV-associated disease.
