Interleukin (IL)-18 synergizes with IL-12 to promote T helper cell (Th)1 responses. Somewhat paradoxically, IL-18 administration alone strongly induces immunoglobulin (Ig)E production and allergic inflammation, indicating a role for IL-18 in the generation of Th2 responses. The ability of IL-18 to induce IgE is dependent on CD4+ T cells, IL-4, and signal(More)
Progressive myoclonic epilepsy (PME) is a group of disorders in which myoclonus is a major component. Patients with PME typically have generalized tonic–clonic or clonic seizures, mental retardation culminating in dementia, and a neurologic syndrome that almost always includes cerebellar dysfunction. It comprises a heterogeneous group of inherited(More)
C57BL/6 (B6) and B6 background STAT6(-/-) mice pretreated with IL-18 plus IL-2 showed prominent intestinal mastocytosis and rapidly expelled implanted adult worms of the gastrointestinal nematode Strongyloides venezuelensis. In contrast, identically pretreated mast cell-deficient W/W(v) mice failed to do so. Thus, activated mucosal mast cells (MMC) are(More)
X-chromosome inactivation (XCI) is an essential mechanism in females that compensates for the genome imbalance between females and males. It is known that XCI can spread into an autosome of patients with X;autosome translocations. The subject was a 5-year-old boy with Prader–Willi syndrome (PWS)-like features including hypotonia, hypo-genitalism,(More)
Plants are able to sense and mediate the balance between carbon (C) and nitrogen (N) nutrient availability to optimize metabolism and growth, described as the C/N response. To clarify the C/N signalling mechanism, C/N-insensitive plants were obtained from an Arabidopsis FOX hunting population, which over-expresses full-length cDNAs for individuals. The(More)
Autoinflammatory syndromes cause sterile inflammation in the absence of any signs of autoimmune responses. Familial cold autoinflammatory syndrome (FCAS) is characterized by intermittent episodes of rash, arthralgia, and fever after exposure to cold stimuli. We have identified a missense mutation in the NLRC4 gene in patients with FCAS. NLRC4 has been known(More)
Serotonin (5-HT)- or thrombin-stimulated platelet intracellular calcium (Ca) mobilization has been reported to be enhanced in patients with bipolar disorders. However, the mechanism of this enhancement is unknown. As a preliminary study, the authors examined the effects of a myosin light chain kinase (MLCK) inhibitor,(More)
PURPOSE To investigate the process of bacterial invasion from the surface to inside prosthetic vascular grafts. METHODS Elastomer-sealed Dacron vascular grafts (ESDVGs) and gelatin-coated Dacron vascular grafts (GCDVGs) were cut into 6-cm segments and placed in a U-shaped configuration on culture plates. Physiological saline was poured inside the grafts(More)
The differentiation of adipocytes is tightly regulated by a variety of intrinsic molecules and also by extrinsic molecules produced by adjacent cells. Dysfunction of adipocyte differentiation causes lipodystrophy, which impairs glucose and lipid homeostasis. Although dysfunction of immunoproteasomes causes partial lipodystrophy, the detailed molecular(More)
We report a childhood case of localization-related epilepsy manifesting frequent gelastic seizures, which were successfully treated with topiramate (TPM) monotherapy. The seizures were not associated with feelings of mirth. High-resolution three-tesla magnetic resonance imaging revealed no structural abnormality. Interictal 18F-fluorodeoxyglucose positron(More)
