Immediate Neutrophil-Variable-T Cell Receptor Host Response in Bacterial Meningitis.

Bacterial meningitis is a life-threatening disease that evokes an intense neutrophil-dominated host response to microbes invading the subarachnoid space. Recent evidence indicates the existence of combinatorial V(D)J immune receptors in neutrophils that are based on the T cell receptor (TCR). Here, we investigated expression of the novel neutrophil TCRαβ-based V(D)J receptors in cerebrospinal fluid (CSF) from human patients with acute-phase bacterial meningitis using immunocytochemical, genetic immunoprofiling, cell biological, and mass spectrometric techniques.

Molecular mimicry, genetic homology, and gene sharing proteomic "molecular fingerprints" using an EBV (Epstein-Barr virus)-derived microarray as a potential diagnostic method in autoimmune disease.

EBV (Epstein-Barr Virus) and other human DNA viruses are associated with autoimmune syndromes in epidemiologic studies. In this work, immunoglobulin G response to EBV-encoded proteins which share regions with human immune response proteins from the human host including ZEBRA (BZLF-1 encoded protein), BALF-2 recombinase expressed primarily during the viral lytic replication cycle, and EBNA-1 (Epstein-Barr Virus Nuclear Antigen) expressed during the viral latency cycle respectively were characterized using a laser-printed micro-array ( PEPperprint.com ).

Technology alignment in the presence of regulatory changes: The case of meaningful use of information technology in healthcare.

Objectives: Using the context of the healthcare sector, this study examines the impact of regulatory change on technology implementation and use. Hospitals are now federally mandated to showcase meaningful use of information technology (IT). We theorize that IT plan scope structured prior to a regulatory change by means of a long-term planning horizon, top management involvement, and steering committee engagement impacts organizations' ability to fulfill meaningful use requirements three to five years later.

Genetics and Molecular Biology of Epstein-Barr Virus-Encoded BART MicroRNA: A Paradigm for Viral Modulation of Host Immune Response Genes and Genome Stability.

Epstein-Barr virus, a ubiquitous human herpesvirus, is associated through epidemiologic evidence with common autoimmune syndromes and cancers. However, specific genetic mechanisms of pathogenesis have been difficult to identify. In this review, the author summarizes evidence that recently discovered noncoding RNAs termed microRNA encoded by Epstein-Barr virus BARF (BamHI A right frame) termed BART (BamHI A right transcripts) are modulators of human immune response genes and genome stability in infected and bystander cells.

Epstein-Barr virus lytic infection promotes activation of Toll-like receptor 8 innate immune response in systemic sclerosis monocytes.

Background: Monocytes/macrophages are activated in several autoimmune diseases, including systemic sclerosis (scleroderma; SSc), with increased expression of interferon (IFN)-regulatory genes and inflammatory cytokines, suggesting dysregulation of the innate immune response in autoimmunity. In this study, we investigated whether the lytic form of Epstein-Barr virus (EBV) infection (infectious EBV) is present in scleroderma monocytes and contributes to their activation in SSc.

Methods: Monocytes were isolated from peripheral blood mononuclear cells (PBMCs) depleted of the CD19+ cell fraction, using CD14/CD16 negative-depletion.

Differential Diagnosis of Chronic Urticaria and Angioedema Based on Molecular Biology, Pharmacology, and Proteomics.

Differential diagnosis of urticaria and angioedema has been based on the phenotype as either acute or chronic depending on the duration of more than 6 to 8 weeks, respectively. Additional subdivisions include poorly defined terms such as idiopathic, spontaneous, or autoimmune. In this article, the author suggests that an increased understanding of the acquired and innate immune system and data from novel proteomic technology have blurred the lines between these categories of diagnosis.

Gene sharing between Epstein-Barr virus and human immune response genes.

Epstein-Barr virus (also termed HHV-4, EBV), a component of the human virome or metagenome, is associated as a co-factor in many common human autoimmune diseases through epidemiologic evidence. Numerous EBV genes are functional as well as structural homologues of important immune response genes. For example, EBV-encoded BCRF1 is a functional homologue of IL-10, a critical cytokine regulator of immune tolerance.

Costs and spillover effects of private insurers' coverage of hepatitis C treatment.

Objectives: Hepatitis C virus (HCV) treatment incentives for private payers may be misaligned because payers must bear immediate costs and may not realize long-term benefits. However, these benefits may accrue to future payers, including Medicare. We examined how and to what extent private payers' current HCV treatment coverage decisions impact Medicare's and private payers' future costs.

Value of expanding HCV screening and treatment policies in the United States.

Objectives: To investigate the value of expanding screening and treatment for hepatitis C virus (HCV) infection in the United States.

Study Design: Discrete-time Markov model.

Methods: We modeled HCV progression and transmission to analyze the costs and benefits of investment in screening and treatment over a 20-year time horizon.

Broad Hepatitis C Treatment Scenarios Return Substantial Health Gains, But Capacity Is A Concern.

Treatment of hepatitis C virus, the most common chronic viral infection in the United States, has historically suffered from challenges including serious side effects, low efficacy, and ongoing transmission and reinfection. Recent innovations have produced breakthrough therapies that are effective in more than 90 percent of patients. These treatments could dramatically reduce the virus's prevalence but are costly.

HIV integrase inhibitors block replication of alpha-, beta-, and gammaherpesviruses.

The catalytic site of the HIV integrase is contained within an RNase H-like fold, and numerous drugs have been developed that bind to this site and inhibit its activity. Herpes simplex virus (HSV) encodes two proteins with potential RNase H-like folds, the infected cell protein 8 (ICP8) DNA-binding protein, which is necessary for viral DNA replication and exhibits recombinase activity in vitro, and the viral terminase, which is essential for viral DNA cleavage and packaging. Therefore, we hypothesized that HIV integrase inhibitors might also inhibit HSV replication by targeting ICP8 and/or the terminase.

Herpesviruses and the microbiome.

The focus of this article will be to examine the role of common herpesviruses as a component of the microbiome of atopic patients and to review clinical observations suggesting that atopic patients might be predisposed to more severe and atypical herpes-related illness because their immune response is biased toward a TH2 cytokine profile. Human populations are infected with 8 herpesviruses, including herpes simplex virus HSV1 and HSV2 (also termed HHV1 and HHV2), varicella zoster virus (VZV or HHV3), EBV (HHV4), cytomegalovirus (HHV5), HHV6, HHV7, and Kaposi sarcoma-associated herpesvirus (termed KSV or HHV8). Herpesviruses are highly adapted to lifelong infection of their human hosts and thus can be considered a component of the human "microbiome" in addition to their role in illness triggered by primary infection.

Urticaria & angioedema: a rational approach to diagnosis and therapy.

Urticaria and angioedema are common allergic manifestations and some forms of this disorder may be increasing in both prevalence and severity due to changes in medications, environment and other unknown factors. This review focuses on a rational approach to differential diagnosis and therapy of the most common forms of urticaria and angioedema.

Identification of a divalent metal cation binding site in herpes simplex virus 1 (HSV-1) ICP8 required for HSV replication.

Herpes simplex virus 1 (HSV-1) ICP8 is a single-stranded DNA-binding protein that is necessary for viral DNA replication and exhibits recombinase activity in vitro. Alignment of the HSV-1 ICP8 amino acid sequence with ICP8 homologs from other herpesviruses revealed conserved aspartic acid (D) and glutamic acid (E) residues. Amino acid residue D1087 was conserved in every ICP8 homolog analyzed, indicating that it is likely critical for ICP8 function.

Analysis of an ankyrin-like region in Epstein Barr Virus encoded (EBV) BZLF-1 (ZEBRA) protein: implications for interactions with NF-κB and p53.

Background: The carboxyl terminal of Epstein-Barr virus (EBV) ZEBRA protein (also termed BZLF-1 encoded replication protein Zta or ZEBRA) binds to both NF-κB and p53. The authors have previously suggested that this interaction results from an ankyrin-like region of the ZEBRA protein since ankyrin proteins such as IκB interact with NF-κB and p53 proteins. These interactions may play a role in immunopathology and viral carcinogenesis in B lymphocytes as well as other cell types transiently infected by EBV such as T lymphocytes, macrophages and epithelial cells.

Autoimmune disease: A role for new anti-viral therapies?

Many chronic human diseases may have an underlying autoimmune mechanism. In this review, the author presents a case of autoimmune CIU (chronic idiopathic urticaria) in stable remission after therapy with a retroviral integrase inhibitor, raltegravir (Isentress). Previous reports located using the search terms "autoimmunity" and "anti-viral" and related topics in the pubmed data-base are reviewed suggesting that novel anti-viral agents such as retroviral integrase inhibitors, gene silencing therapies and eventually vaccines may provide new options for anti-viral therapy of autoimmune diseases.

Paleo-immunology: evidence consistent with insertion of a primordial herpes virus-like element in the origins of acquired immunity.

Background: The RAG encoded proteins, RAG-1 and RAG-2 regulate site-specific recombination events in somatic immune B- and T-lymphocytes to generate the acquired immune repertoire. Catalytic activities of the RAG proteins are related to the recombinase functions of a pre-existing mobile DNA element in the DDE recombinase/RNAse H family, sometimes termed the "RAG transposon".

Methodology/principal Findings: Novel to this work is the suggestion that the DDE recombinase responsible for the origins of acquired immunity was encoded by a primordial herpes virus, rather than a "RAG transposon.
