Antiviral and Antioxidant Properties of Echinochrome A.

Mar Drugs 2018 Dec 15;16(12). Epub 2018 Dec 15.

G.P. Somov Institute of Epidemiology and Microbiology, FEB RAS, Vladivostok 690087, Russia.

The aim of this study was to examine the in vitro antioxidant and antiviral activities of echinochrome A and echinochrome-based antioxidant composition against tick-borne encephalitis virus (TBEV) and herpes simplex virus type 1 (HSV-1). The antioxidant composition, which is a mixture of echinochrome A, ascorbic acid, and α-tocopherol (5:5:1), showed higher antioxidant and antiviral effects than echinochrome A. We suppose that echinochrome A and its composition can both directly affect virus particles and indirectly enhance antioxidant defense mechanisms in the hosting cell. Read More

Missing Cases of Herpes simplex virus (HSV) Infection of the Central Nervous System Applying Reller Criteria for HSV PCR testing: A Multicenter Study.

J Clin Microbiol 2018 Nov 28. Epub 2018 Nov 28.

Microbiology Service, Hospital Clínico Universitario, Instituto de Investigación INCLIVA, Valencia, Spain

Previous studies suggested that Herpes simplex virus (HSV) PCR testing can be safely deferred in patients with normal cerebrospinal fluid (CSF) white blood cell (WBC) counts and protein levels as long as they are older than two years of age and are not immunocompromised, the so-called Reller criteria. In this multicenter study, we retrospectively assessed the validity of this screening criteria in our setting. A total of 4,404 CSF specimens submitted to the respective microbiology laboratories at the participating hospitals between 2012 and 2018 for HSV PCR testing were included. Read More

Clinical management of herpes simplex virus infections: past, present, and future.

F1000Res 2018 31;7. Epub 2018 Oct 31.

Department of Pathobiology, School of Veterinary Medicine, Louisiana State University, Baton Rouge, LA, 70803, USA.

Infection with herpes simplex virus (HSV) types 1 and 2 is ubiquitous in the human population. Most commonly, virus replication is limited to the epithelia and establishes latency in enervating sensory neurons, reactivating periodically to produce localized recurrent lesions. However, these viruses can also cause severe disease such as recurrent keratitis leading potentially to blindness, as well as encephalitis, and systemic disease in neonates and immunocompromised patients.

Corroboration of a Major Role for Herpes Simplex Virus Type 1 in Alzheimer's Disease.

Authors:
Ruth F Itzhaki

Front Aging Neurosci 2018 19;10:324. Epub 2018 Oct 19.

Nuffield Department of Clinical Neurosciences, University of Oxford, Oxford, United Kingdom.

Strong evidence has emerged recently for the concept that herpes simplex virus type 1 (HSV1) is a major risk for Alzheimer's disease (AD). This concept proposes that latent HSV1 in brain of carriers of the type 4 allele of the apolipoprotein E gene (APOE-ε4) is reactivated intermittently by events such as immunosuppression, peripheral infection, and inflammation, the consequent damage accumulating, and culminating eventually in the development of AD. Population data to investigate this epidemiologically, e. Read More

Department of Neurology, Felsenstein Medical Research Institut, Rabin Medical Center, Beilinson Hospital, Beilinson Campus, Petach Tikva 49100, Israel; Sackler Faculty of Medicine, Tel Aviv University, Tel Aviv 6997801, Israel.

The 3 neurotropic human herpes viruses, herpes simplex virus (HSV) type 1 and 2, and varicella-zoster virus (VZV) are capable of establishment of latent viral infection in trigeminal and dorsal root ganglia. HSV-1, and more rarely HSV-2, carries the potential to cause meningoencephalitis, with devastating clinical consequences. Immediate diagnosis, based on clinical presentation, MRI imaging, and molecular diagnosis by polymerase chain reaction, and initiation of therapy are mandatory to reduce mortality and neurologic permanent sequelae.

Combating herpesvirus encephalitis by potentiating a TLR3-mTORC2 axis.

Nat Immunol 2018 Oct 10;19(10):1071-1082. Epub 2018 Sep 10.

Division of Innate Immunity, Department of Microbiology and Immunology, The Institute of Medical Science, The University of Tokyo, Tokyo, Japan.

TLR3 is a sensor of double-stranded RNA that is indispensable for defense against infection with herpes simplex virus type 1 (HSV-1) in the brain. We found here that TLR3 was required for innate immune responses to HSV-1 in neurons and astrocytes. During infection with HSV-1, TLR3 recruited the metabolic checkpoint kinase complex mTORC2, which led to the induction of chemokines and trafficking of TLR3 to the cell periphery. Read More

Insights into the pathogenesis of herpes simplex encephalitis from mouse models.

Mamm Genome 2018 08 23;29(7-8):425-445. Epub 2018 Aug 23.

Department of Human Genetics, McGill University, Montreal, QC, Canada.

A majority of the world population is infected with herpes simplex viruses (HSV; human herpesvirus types 1 and 2). These viruses, perhaps best known for their manifestation in the genital or oral mucosa, can also cause herpes simplex encephalitis, a severe and often fatal disease of the central nervous system. Antiviral therapies for HSV are only partially effective since the virus can establish latent infections in neurons, and severe pathological sequelae in the brain are common. Read More

Human iPSC-derived trigeminal neurons lack constitutive TLR3-dependent immunity that protects cortical neurons from HSV-1 infection.

Proc Natl Acad Sci U S A 2018 09 28;115(37):E8775-E8782. Epub 2018 Aug 28.

Center for Stem Cell Biology, Sloan Kettering Institute for Cancer Research, New York, NY 10065;

Herpes simplex virus type 1 (HSV-1) encephalitis (HSE) is the most common sporadic viral encephalitis in Western countries. Some HSE children carry inborn errors of the Toll-like receptor 3 (TLR3)-dependent IFN-α/β- and -λ-inducing pathway. Induced pluripotent stem cell (iPSC)-derived cortical neurons with TLR3 pathway mutations are highly susceptible to HSV-1, due to impairment of cell-intrinsic TLR3-IFN immunity. Read More

Both IRF3 and especially IRF7 play a key role to orchestrate an effective cerebral inflammatory response in a mouse model of herpes simplex virus encephalitis.

J Neurovirol 2018 Dec 9;24(6):761-768. Epub 2018 Aug 9.

Research Center in Infectious Diseases of the CHU of Quebec and Laval University, 2705 Boul. Laurier, Quebec City, QC, G1V 4G2, Canada.

The impact of a deficiency in interferon regulatory factor (IRF)3 and IRF7 was evaluated in an herpes simplex virus encephalitis (HSE) model. Compared to wild type (WT), the mortality rates of infected IRF3 and IRF7 mice were higher and associated with increased brain viral titers. At a critical time post-infection, IRF7 mice exhibited a deficit in IFN-β production. Read More

Increased level of compleasomes in cerebrospinal fluid of patients with herpes simplex encephalitis.

J Neurovirol 2018 Dec 9;24(6):702-711. Epub 2018 Aug 9.

Department of Infectious Diseases, Institute of Biomedicine, University of Gothenburg, PO Box 420, S-405 30, Gothenburg, Sweden.

Herpes simplex encephalitis (HSE) is a common cause of viral encephalitis (HSV-1) characterised by pronounced inflammation and elevated intracranial pressure. We have shown in a rat model that HSV-1 infection causes an interaction between complement factors and proteasomes, leading to formation of proteasome/complement complexes (compleasomes). Exposure of the proteasome regulatory subunit antisecretory factor 1 (AF1) leads to a decrease in intracranial pressure. Read More

Glycans with Antiviral Activity from Marine Organisms.

Results Probl Cell Differ 2018 ;65:439-475

Department of Earth, Environment and Life Sciences, University of Genova, Genova, Italy.

There remains today a critical need for new antiviral agents, particularly in view of the alarming increase in drug resistance and associated issues. The marine environment has been a prolific contributor towards the identification of novel therapeutic agents in the recent few decades. Added to this, glycans (or carbohydrate- or sugar-based compounds) have in very recent decades made outstanding contributions to the development of novel therapeutics. Read More

Insular cortex lesion and autonomic instability in a herpes simplex virus encephalitis patient.

J Neurovirol 2018 Oct 9;24(5):649-651. Epub 2018 Jul 9.

Department of Neurology, Hiroshima City Asa Hospital, Hiroshima, Japan.

The cardiovascular system is regulated by a central autonomic network (CAN) consisting of the insular cortex, anterior cingulate gyrus, and amygdala. Because the insular cortex often tends to be damaged in patients with herpes simplex virus (HSV) encephalitis, the autonomic instability observed in these patients was suggested to be moderated by an insular cortex lesion. Here, we report the case of a 51-year-old Japanese male who was hospitalized following a collapse 5 days earlier; he was diagnosed as herpes encephalitis. Read More

Department of Natural Drugs, Faculty of Pharmacy, University of Veterinary and Pharmaceutical Sciences Brno, Palackého třída 1946/1, 612 42 Brno, Czech Republic.

Herpes simplex virus (HSV) causes numerous mild-to-serious human diseases, including mucocutaneous herpes infections and life-threatening herpes encephalitis. Moreover, herpes viral lesions can be complicated by inflammation and secondary bacterial infections. The development of resistance to antiviral drugs along with the undesirable side effects of these drugs are relevant argue for the development of new anti-HSV drugs with diverse mechanisms of action.
