Paeoniflorin непосредственно ставит ENO1 перед инхибитом M1 поляризацию микроглий/макропатических и смягчающих болезнь EAE.

В настоящее время хронические аутоиммунные заболевания, связанные с множественным склерозом (MS), остаются неизлечимыми. Паеонифлорин (PF), который представляет собой монотерпеновый глюкосид, полученный из Paeonia lactiflora Pall, признается за нейрозащитные и антивоспалительные свойства. Однако точный механизм, с помощью которого ПФ регулирует НР, является неясным. Эта работа направлена на разъяснение основополагающих механизмов PF в EAE, хорошо зарекомендовавшей себя животной модели MS, и на выявление целевых белков, которые PF действует непосредственно. Наши результаты показали, что управле

A unique finding of the basilar artery.

Variants of the posterior intracranial circulation are important for surgeon, interventionalists and radiologists. Herein, a unique configuration of the basilar artery is reported. A 54-year-old man with a history of COPD, hypothyroidism, smoking, and hyperlipidemia presented to an outside institution with nausea, confusion, altered mental status, and ataxia. The patient was evaluated for stroke. Imaging revealed rotation of the basilar apex of 180 degrees, fetal configuration of the posterior communicating artery, right posterior cerebral artery filling from the left vertebral artery, and dup

Thymosins in multiple sclerosis and its experimental models: moving from basic to clinical application.

BACKGROUND: Multiple sclerosis (MS) afflicts more than 2.5 million individuals worldwide and this number is increasing over time. Within the past years, a great number of disease-modifying treatments have emerged; however, efficacious treatments and a cure for MS await discovery. Thymosins, soluble hormone-like peptides produced by the thymus gland, can mediate immune and non-immune physiological processes and have gained interest in recent years as therapeutics in inflammatory and autoimmune diseases. METHODS: Pubmed was searched with no time constraints for articles using a combination of t

Histologic characterization of eosinophilic encephalitis in horses in Florida.

Eosinophils within the central nervous system are abnormal and are usually associated with fungal or parasitic infections in horses. Causative agents include Halicephalobus gingivalis, Sarcocystis neurona, and Neospora hughesi. Confirmation of these organisms via specific testing is typically not performed, and final diagnoses are often presumptive. With molecular technology, many of these organisms can now be confirmed. This is important for emerging and zoonotic pathogens, including Angiostrongylus cantonensis, an emerging parasite of interest in the southeastern United States. We retrospect

Human transcriptome response to immunization with live-attenuated Venezuelan equine encephalitis virus vaccine (TC-83): Analysis of whole blood.

Venezuelan equine encephalitis virus (VEEV) is an important human and animal alphavirus pathogen transmitted by mosquitoes. The virus is endemic in Central and South America, but has also caused equine outbreaks in southwestern areas of the United States. In an effort to better understand the molecular mechanisms of the development of immunity to this important pathogen, we performed transcriptional analysis from whole, unfractionated human blood of patients who had been immunized with the live-attenuated vaccine strain of VEEV, TC-83. We compared changes in the transcriptome between naïve ind

The ubiquitin proteasome system plays a role in venezuelan equine encephalitis virus infection.

Many viruses have been implicated in utilizing or modulating the Ubiquitin Proteasome System (UPS) to enhance viral multiplication and/or to sustain a persistent infection. The mosquito-borne Venezuelan equine encephalitis virus (VEEV) belongs to the Togaviridae family and is an important biodefense pathogen and select agent. There are currently no approved vaccines or therapies for VEEV infections; therefore, it is imperative to identify novel targets for therapeutic development. We hypothesized that a functional UPS is required for efficient VEEV multiplication. We have shown that at non-tox

[Production of 70 kDa recombinant human heat shock protein in baculovirus expression system and assessment of its antiviral activity].

Using wild white-tailed deer to detect eastern equine encephalitis virus activity in Maine.

Serum from 226 free-ranging white-tailed deer (Odocoileus virginianus) was screened for Eastern Equine Encephalitis Virus (EEEV) antibodies using plaque reduction neutralization tests. EEEV antibodies were detected in 7.1% of samples. This is the first time EEEV antibodies have been detected in O. virginianus populations in the state of Maine (ME). The highest percentage of EEEV positive sera was in Somerset County (19%) in central ME, and this is the first time that EEEV activity has been detected in that County. EEEV RNA was not detected in any of the 150 harvested deer brain samples submitt

Immunogenicity and protective efficacy of a DNA vaccine against Venezuelan equine encephalitis virus aerosol challenge in nonhuman primates.

A study to evaluate the immunogenicity and protective efficacy of a Venezuelan equine encephalitis virus (VEEV) DNA vaccine in an aerosol model of nonhuman primate infection was performed. Cynomolgus macaques vaccinated with a plasmid expressing the 26S structural genes of VEEV subtype IAB by particle-mediated epidermal delivery (PMED) developed virus-neutralizing antibodies. No serum viremia was detected in two out of three macaques vaccinated with the VEEV DNA after aerosol challenge with homologous virus, while one displayed a low viremia on a single day postchallenge. In contrast, all thre

Cotton rats and house sparrows as hosts for North and South American strains of eastern equine encephalitis virus.

Eastern equine encephalitis virus (EEEV; family Togaviridae, genus Alphavirus) is an arbovirus that causes severe disease in humans in North America and in equids throughout the Americas. The enzootic transmission cycle of EEEV in North America involves passerine birds and the ornithophilic mosquito vector, Culiseta melanura, in freshwater swamp habitats. However, the ecology of EEEV in South America is not well understood. Culex (Melanoconion) spp. mosquitoes are considered the principal vectors in Central and South America; however, a primary vertebrate host for EEEV in South America has not

Effect of T-705 treatment on western equine encephalitis in a mouse model.

A mouse model of western equine encephalitis (WEE) was characterized for use in antiviral studies. Virus was detected in several tissues, most notably an average titer of 9.5+/-1.1 log(10) 50% cell culture infectious doses (CCID(50))/g tissue in the brains of infected animals. Signs of WEE included limb weakness, paralysis, involuntary spasms or extension of limbs, clenching of paws, hunching, ruffling of fur, and eye exudates, many of which are indicative of neurological disease. The pyrazinecarboxamide derivative, T-705, was found to be active in Vero cells against WEE virus (WEEV) with an 9

A heuristic indication and warning staging model for detection and assessment of biological events.

OBJECTIVE: This paper presents a model designed to enable rapid detection and assessment of biological threats that may require swift intervention by the international public health community. DESIGN: We utilized Strauss' grounded theory to develop an expanded model of social disruption due to biological events based on retrospective and prospective case studies. We then applied this model to the temporal domain and propose a heuristic staging model, the Wilson-Collmann Scale for assessing biological event evolution. MEASUREMENTS: We retrospectively and manually examined hard copy archival l

[Multiple sclerosis in children: clarifying its place among the demyelinating spectrum].

Multiple sclerosis (MS) is an autoimmune disease caused by the destruction of the myelin layer and the nervous fibers, and secondary by a progressive neuronal damage. It is characterized by episodes of demyelination disseminated in time and space in different areas of the white matter of the CNS which includes periventricular region, spinal cord, brain stem, cerebellum and optical nerve. Due to the confusing differential diagnosis of MS in children with other demyelinating diseases such as ADEM, it is important to reach this diagnosis when there is proof of white matter lesions disseminated in

Venezuelan equine encephalitis virus, southern Mexico.

Equine epizootics of Venezuelan equine encephalitis (VEE) occurred in the southern Mexican states of Chiapas in 1993 and Oaxaca in 1996. To assess the impact of continuing circulation of VEE virus (VEEV) on human and animal populations, serologic and viral isolation studies were conducted in 2000 to 2001 in Chiapas State. Human serosurveys and risk analyses indicated that long-term endemic transmission of VEEV occurred among villages with seroprevalence levels of 18% to 75% and that medical personnel had a high risk for VEEV exposure. Seroprevalence in wild animals suggested cotton rats as pos

Suspected protozoal myeloencephalitis in a two-month-old colt.

A two-month-old Appaloosa colt developed neurological signs shortly after birth involving deficits affecting cranial nerves IV, VII, VIII, IX, X and XII, and possibly nerve VI. The most likely differential diagnoses were congenital anomalies, meningoencephalitides, trauma or nutritional causes. The foal was investigated by the analysis of cerebrospinal fluid (CSF), electromyelography (EMG), brain auditory evoked responses, magnetic resonance imaging (MRI), peripheral nerve biopsy, and Western blot analysis for the presence of intrathecal antibodies to Sarcocystis neurona, the causative agent o
