1. By the bites of stegomyia mosquitoes carrying neurotropic yellow fever virus, encephalitis has been produced both in white mice and in rhesus monkeys. 2. The fixed neurotropic strain of virus cannot be maintained in the mosquito host as well as can the viscerotropic strains. This is doubtless attributable in part to a smaller amount of virus ingested, because of paucity in the blood stream o...

The neurotropic strain of Rift Valley fever virus produces encephalitis when inoculated intracerebrally in lambs. Subcutaneous inoculation into sheep and lambs does not cause illness. Immunity against the pantropic strain follows the subcutaneous injection of neurotropic virus in sheep and lambs. Two species of monkey, Macaca mulatta, the rhesus monkey, and M. irus, the crab-eating macacque, ar...

1. The thermal inactivation time at 41.5 degrees C. of the H. F. and Frank strains of herpes simplex virus, under the conditions described, was 80 hours. 2. A strain of herpes virus recently recovered from a patient treated with a physically induced fever had a thermal inactivation time of 50 hours at 41.5 degrees C. 3. The neurotropic factor of the H. F. and Frank strains of virus was more res...

Vaccination with DNA encoding a myelin basic protein peptide suppresses Lewis rat experimental autoimmune encephalomyelitis (EAE) induced with the same peptide. Additional myelin proteins, such as myelin oligodendrocyte glycoprotein (MOG), may be important in multiple sclerosis. Here we demonstrate that DNA vaccination also suppresses MOG peptide-induced EAE. MOG(91-108) is encephalitogenic in ...

OBJECTIVE Perineural invasion of cholangiocarcinoma happens in the early stage of the disease but is often not recognized until its later stages. Research about the behaviour and mechanism of perineural invasion by cholangiocarcinoma is urgently needed for a useful new model. The aim of this work is to establish a novel model to address the problem. DESIGN Neural cells and cholangiocarcinoma ...

Neurobehavioral disorder is a serious consequence of a number of viral infections in the central nervous system (CNS). A line of evidence has demonstrated that viral infections are associated with disturbances in neural functions that may be caused by alteration of the brain homeostasis. Here, we examined the role of viral persistent infection in neuropsychiatric disorders by generating a trans...

Enterovirus 70 (EV70) is one of several human enteroviruses that exhibit a propensity for infecting the central nervous system (CNS). The mechanisms by which neurotropic enteroviruses gain access to and invade the CNS are poorly understood. One possibility is that circulating leukocytes become infected and carry neurotropic enteroviruses to the CNS. We examined the ability of EV70 to infect cel...

Transcription of the gene encoding brain-derived neurotropic factor (BDNF) is induced in response to a wide variety of extracellular stimuli via the activation of a complex array of transcription factors. However, to what degree individual transcription factors confer specificity upon the regulation of Bdnf is poorly understood. Previous studies have shown that members of the myocyte enhancer f...
