BACKGROUND In studies on the possible role of viruses in the aetiopathogenesis of Alzheimer's disease, herpes simplex virus type 1 (HSV1) DNA was detected by the polymerase chain reaction (PCR) in a high proportion of normal elderly people and of patients with Alzheimer's disease. The combination of HSV1 and a host factor, the type 4 allele of the gene for apolipoprotein E, is a strong risk fac...

INTRODUCTION Little is known about the role of herpes simplex virus (HSV) type 1 (HSV1) in the epidemiology of genital herpes in Canada. Data on herpes viral cultures for two consecutive years obtained from L'Hôpital Dr GL Dumont, which performs all the viral culture testing in New Brunswick, were reviewed. It was hypothesized that HSV1 was the main cause of genital herpes in New Brunswick. M...

UNLABELLED The two human neurotropic alphaherpesviruses varicella-zoster virus (VZV) and herpes simplex virus type 1 (HSV1) both establish latency in sensory ganglia. Human trigeminal ganglia are known to frequently harbor both viruses, and there is evidence to suggest the presence of both VZV and HSV1 DNA in the same neuron. We ask here whether VZV and HSV1 can exclude themselves and each othe...

Background and Aims: Herpes simplex virus type 1 (HSV1) remains a potentially serious health problem world wide. All infected people, including asymptomatic ones, are potential sources for virus transmission. Virus envelope contains at least 13 glycoproteins, which glycoprotein D is the major target of immune responses. The aim of this study was development of a specific method that is a more...

PURPOSE To localize the sites of HSV1 latency in mice after a primary infection induced by injection into the lip and to assess their connection to the eye. METHODS The SC16 strain of HSV1, or a recombinant virus containing the HSV1 latency-associated transcript (LAT)-promoter driving expression of the LacZ reporter gene, were injected into the left upper lip. Tissues from animals killed at 6...

Herpes simplex type 1 (HSV1) replicates in epithelial cells and secondarily enters local sensory neuronal processes, traveling retrograde to the neuronal nucleus to enter latency. Upon reawakening newly synthesized viral particles travel anterograde back to the epithelial cells of the lip, causing the recurrent cold sore. HSV1 co-purifies with amyloid precursor protein (APP), a cellular transme...

Abstract Background qPCR is being widely used for STI (Sexually Transmitted Infection) testing as the most sensitive and accurate diagnostic method. Genesystem developed a novel qPCR-based platform, called Genoplex chip, which enables simultaneous detection of multiple sexually transmitted pathogens with single test. chip realized high multiplex (up to 14 by pipetting), making it easy fast proc...

Background and Aims: Herpes simplex virus (HSV) is responsible for several significant human viral diseases, with severity ranging from subclinical to fatal infection. Herpes simplex virus type 2 (HSV2) infections are more commonly seen in association with the genitalia and surrounding areas, and can be transmitted to newborns during childbirth. Generalized infections in newborns are also predo...

Is AD caused by viral infection? 2 ARC Publishing HSV1 infection of a wide variety of cells in culture, including human neuronal-type, causes accumulation of beta amyloid (Aβ) and of abnormally phosphorylated tau (P-tau)—the main components respectively of the characteristic amyloid plaques and neurofibrillary tangles seen in AD brains. The increase in Aβ probably occurs via activation of PKR a...

BACKGROUND Herpes simplex virus (HSV) is among the most common sexually transmitted pathogens in the United States and worldwide. HSV has a high incidence of undetected cases. In addition, there is no treatment, and there is a lack of knowledge why disparities among populations exist. Research studies suggest that fat tissue may participate in body's immune responses, and the impact of obesity ...
