Background: Dysphagia is a potentially fatal symptom of Parkinson's disease (PD) and is characterized by frequent silent aspiration, a known risk factor for aspiration pneumonia. A previous study has reported that the dopamine agonist rotigotine (levodopa equivalent dose of 60 mg/day) delivered via transdermal patch improves swallowing function more effectively than oral levodopa (200 mg/day), highlighting the importance of continuous dopaminergic stimulation (CDS) in managing dysphagia. To achieve CDS, patients with advanced PD may require device-assisted therapies (DATs), including levodopa-carbidopa intestinal gel (LCIG), which have significantly improved swallowing function on some measures.

Demyelination in the CNS provokes hyperalgesia, negative emotions, and/or cognitive impairment. Cuprizone (CPZ)-induced demyelination is a major demyelinating disease model for rodents.

Background: Huntington's disease is an autosomal dominant inherited disorder characterized by personality changes (such as irritability and restlessness) and psychotic symptoms (such as hallucinations and delusions). When the personality changes become noticeable, involuntary movements (chorea) also develop. The disease is caused by the CAG repeat expansion in the coding region of the HTT gene, and the diagnosis is based on the presence of this expansion.

We investigated the effects of loquat leaf powder and methanol extract in human neuroglioma H4 cells stably expressing the Swedish-type APP695 (APP-H4 cells) and C57BL/6 J mice. Surprisingly, the extract greatly enhanced cellular amyloid-beta peptide (Aβ) 42 productions in APP-H4 cells.

To determine the contribution of microglia to motor function during CPZ-induced demyelination, the microglia of mice in the CPZ-model were depleted using PLX3397 (PLX), an orally bioavailable selective colony stimulating factor 1 receptor inhibitor. PLX treatment aggravated motor dysfunction as shown by the pole, beam walk, ladder walk, and rotarod tests.

Introduction: Among the fatty acid ethanolamides (FAEs), oleoylethanolamide (OEA), linoleoylethanolamide (LEA), and palmitoylethanolamide (PEA) are reported to be involved in feeding regulation. In particular, OEA is well characterized as a satiety signal. Following food consumption, OEA is synthesized from oleic acid (OA) an -acyl phosphatidylethanolamine-specific phospholipase D-dependent pathway in the gastroenterocytes, and OEA induces satiety by recruiting sensory fibers.

Herein, we reported the characteristics of super-elderly patients, aged over 80 years, with Guillain-Barré syndrome (GBS), a typical neuroimmune disease.
Methods: During the period 2019-2021, 74 patients over the age of 80 years diagnosed with GBS at Kindai university were analyzed as the super-elderly group patients.
The orphan receptor, G protein-coupled receptor 137 (GPR137), is an integral membrane protein involved in several types of cancer. GPR137 is expressed ubiquitously, including in the central nervous system (CNS). We established a GPR137 knockout (KO) neuro2A cell line to analyze GPR137 function in neuronal cells.

The valence band maxima of Li conductive amorphous lithium phosphorus oxynitride (LiPON) electrolyte depend on the chemical bonding states, and isolated nonbonding oxygen raises them. In contrast, the conduction band minima of the LiPON are independent of the composition and the values are less than the work function of Li.

Mushrooms contain various biological response modifiers (BRMs) and are widely used in traditional Chinese medicine in East Asian countries. To investigate whether mushrooms have potential beneficial effects on MS, we administered mushrooms to cuprizone (bis-cyclohexanone-oxalyldihydrazone, CPZ)-induced MS model mice.

Ophthalmoplegia is a common neurological finding in Miller Fisher syndrome (MFS), but acute eye movement-retained internal ophthalmoplegia is a rare variant of MFS. In this report, we present three cases of acute eye movement-retained internal ophthalmoplegia; IgG anti-GQ1b antibodies were detected in all patients. We reviewed a total of 13 cases, including 10 previously reported cases, and revealed that IgG anti-GQ1b antibodies were identified in all but one patient.

We previously reported that a surge in prostaglandin D (PGD) production and PGD-induced microglial activation could provoke neuroinflammation. We also reported that a lipid sensor GPR120 (free fatty acid receptor 4), which is expressed in intestine, could be activated by polyunsaturated fatty acids (PUFA), thereby mediating secretion of glucagon-like peptide-1 (GLP-1).

Octodon degus is said to be one of the most human-like rodents because of its improved cognitive function. Focusing on its high sociality, we cloned and characterized some sociality-related genes of degus, in order to establish degus as a highly socialized animal model in molecular biology. We cloned degus Neurexin and Neuroligin as sociality-related genes, which are genetically related to autism spectrum disorder in human.

Eosinophilic gastroenteritis (EGE) is a chronic allergic disorder characterized by infiltration of eosinophils in the gastrointestinal (GI) tract and hypereosinophilia. Although T helper type 2 (Th2) responses play pathogenic roles in EGE, roles of innate immunity cytokines including IL-6 and TNF-α have been poorly defined. Here, we describe a case of EGE exhibiting accumulation of eosinophils in the upper GI mucosa and hypereosinophilia.

Oleoylethanolamide (OEA), a well-known satiety factor, is produced during feeding in the proximal intestine. Enterocytes sense oleic acid in dietary fat via CD36 and convert it to OEA through NAPE-PLD dependent or independent pathways. The satiety function of OEA is known to involve peroxisome proliferator-activated receptor type-α (PPAR-α).
