Interleukin-6 (IL-6) is an inflammatory cytokine produced in many tissues, including the cornea and trigeminal ganglion. IL-6 acts by binding to its specific receptor, stimulating a cascade of signal proteins that induce the transcription factors NF-IL6 and STAT3. These IL-6-induced transcription factors change cellular gene transcription. Neutralization of(More)
West Nile virus (WNV), a category B pathogen endemic in parts of Africa, Asia and Europe, emerged in North America in 1999, and spread rapidly across the continental U.S. Outcomes of infection with WNV range from asymptomatic to severe neuroinvasive disease manifested as encephalitis, paralysis, and/or death. Neuroinvasive WNV disease occurs in less than(More)
Multiple sclerosis (MS) is a demyelinating disease of unknown origin that affects the central nervous system of an estimated 400,000 Americans. GBV-C or hepatitis G is a flavivirus that is found in the serum of 1-2% of blood donors. It was originally associated with hepatitis, but is now believed to be a relatively non-pathogenic lymphotropic virus. Fifty(More)
Deep sequencing allows for a rapid, accurate characterization of microbial DNA and RNA sequences in many types of samples. Deep sequencing (also called next generation sequencing or NGS) is being developed to assist with the diagnosis of a wide variety of infectious diseases. In this study, seven frozen brain samples from deceased subjects with recent(More)
Multiple sclerosis (MS) is a chronic demyelinating disease of the central nervous system, which often follows a relapsing-remitting (RR) course with discrete attacks. MS attacks have been associated with upper respiratory infections (URIs), but the specific viruses responsible have not been identified. We studied a cohort of 16 RRMS patients experiencing(More)
Cytokines are hormones once thought to be restricted to the immune system produced solely by hematopoietic-derived cells and acting on receptors expressed by cells of the immune system. However, it is now clear that many cytokines are produced not only by lymphocytes, monocytes, granulocytes, and dendritic cells but are also synthesized by cells outside the(More)
The gastrointestinal tract (GIT) is the most common extracutaneous organ system damaged in systemic sclerosis (SSc) and is the presenting feature in 10% of patients. The esophagus as the portion of the GIT is the most commonly affected and there is an association of gastroesophageal reflux (GER) with SSc interstitial lung disease (ILD). Thus, an aggressive(More)
The First International Scientific Conference on Human Endogenous Retroviruses (HERVs) and Disease, Lyon-France, May 26-27th 2015, brought together scientific and medical specialists from around the world investigating the involvement of human endogenous retroviruses (HERVs) in complex human diseases.
Our group has recently described a gene on human chromosome 21, the Cold Sore Susceptibility Gene-1 (CSSG-1, also known as C21orf91), which may confer susceptibility to frequent cold sores in humans. We present here a genotype-phenotype analysis of CSSG-1 in a new, unrelated human population. Seven hundred fifty-eight human subjects were enrolled in a(More)
The authors hypothesized that environmental stimuli induce cytokines that act through an intracellular cascade, which includes signal transducers and activators of transcription (STATs), to change herpes simplex virus (HSV) gene expression, thereby inducing viral reactivation. The HSV type 1 (HSV-1) latency-associated transcript (LAT) gene regulates viral(More)
