In Drosophila, the gustatory receptor (Gr) gene family contains 60 family members that encode 68 proteins through alternative splicing. Some gustatory receptors (Grs) are involved in the sensing of sugars, bitter substrates, CO(2), pheromones, and light. Here, we systematically examined the expression of all 68 Grs in abdominal neurons which project to the(More)
Mitochondrial dysfunction is a common and prominent feature of many neurodegenerative diseases, including prion diseases; it is induced by oxidative stress in scrapie-infected animal models. In previous studies, we found swelling and dysfunction of mitochondria in the brains of scrapie-infected mice compared to brains of controls, but the mechanisms(More)
Normal cellular prion protein (PrP(C)) is highly expressed in the central nervous system. The Zürich I Prnp-deficient mouse strain did not show an abnormal phenotype in initial studies, however, in later studies, deficits in exploratory behavior and short- and long-term memory have been revealed. In the present study, numerous autophagic vacuoles were found(More)
The gastrointestinal tract is emerging as a major site of chemosensation in mammalian studies. Enteroendocrine cells are chemosensory cells in the gut which produce regulatory peptides in response to luminal contents to regulate gut physiology, food intake, and glucose homeostasis, among other possible functions. Increasing evidence shows that mammalian(More)
BACKGROUND AND PURPOSE The level of 14-3-3 protein in the cerebrospinal fluid (CSF) is increased in Creutzfeldt-Jakob disease (CJD) patients, which has led to it being used as a clinical biomarker for the ante-mortem diagnosis of human prion diseases. However, the specificity of the 14-3-3 protein is less reliable for CJD diagnosis. Newly developed assays(More)
We report a rare case of neuro-Behcet's disease (NBD) presenting as an inflammatory pseudotumor in the brain. A 52-year-old woman was evaluated for subacute dizziness and headache. Brain magnetic resonance (MR) imaging showed a right cerebellar mass, which disappeared 2 weeks later. After a year, recurrent mucocutaneous manifestations of Beh et's disease(More)
BACKGROUND The role of glycated hemoglobin (HbA1c) in the prediction of ischemic stroke in non-diabetic subjects is not clear. We performed a study to analyze the role of HbA1c in the risk prediction of ischemic stroke in non-diabetic Korean males adult. METHODS A total of 307 non-diabetic male patients with ischemic stroke were enrolled, and 253(More)
The elevation of nitric oxide (NO) within the central nervous system (CNS) is known to be associated with the pathogenesis of neurodegenerative diseases such as HIV-associated dementia (HAD), brain ischemia, Parkinson's disease, and Alzheimer's disease. NO is enzymatically formed by the enzyme nitric oxide synthase (NOS). There are two forms of NOS, the(More)
Pathogen expulsion from the gut is an important defense strategy against infection, but little is known about how interaction between the intestinal microbiome and host immunity modulates defecation. In Drosophila melanogaster, dual oxidase (Duox) kills pathogenic microbes by generating the microbicidal reactive oxygen species (ROS), hypochlorous acid(More)
which permits unrestricted non-commercial use, distribution, and reproduction in any medium, provided the original work is properly cited. We appreciate the interest and comments on our study, " Higher glycated hemoglobin level is associated with increased risk for ischemic stroke in non-diabetic Korean male adults, " which was published in Diabetes &(More)
