Since we introduced cultured dorsal root ganglia (DRG) neurons from streptozotocin (STZ)-induced diabetic mice as "an in vitro model to study diabetic neuropathy" (Sotelo et al., 1991), more than 30 papers have been devoted to the study of diabetic neuropathy with culture systems of neurons and Schwann cells derived from adult animals. So far, methods for… (More)
PURPOSE To investigate the effects of lysosomal storage on the morphologic appearance and the neurite outgrowth capability of the retina in a mouse model of G(M2) gangliosidosis (Sandhoff disease). METHODS Histopathologic appearances of retinas in Sandhoff (SD) mice at 3 and 4 months of age were examined by light and electron microscopy. Retinas of SD… (More)
We developed a new in vivo electroporation method to deliver genes into retinal ganglion cells (RGCs). Efficiency and degree of tissue damage were evaluated using green fluorescent protein (GFP) gene and TUNEL. Soon after the intravitreous injection of the GFP gene, electroporation (five electric pulses of 99 ms duration each and 12V/cm delivered twice 5… (More)
We developed an in vivo electroporation method to introduce foreign genes into retinal ganglion cells (RGCs). After the intravitreous injection of the plasmid gene (20 mug), five electric pulses (6 V/cm, 100 ms duration) were each delivered twice with 5 min interval to the rat eye using a contact lens-type electrode (cathodal) attached to the cornea and a… (More)
To investigate the capability of neurite regeneration from retinal ganglion cells (RGCs) in an adult human retina and to evaluate the effect of neurotrophin on the neurite regeneration, an in vitro model for retinal explants was developed. A human retina was obtained from a 70 year old patient with retrobulbar carcinoma. The retina was excised and the… (More)
PURPOSE To investigate the effect of c-fos on apoptotic cell death and regeneration of damaged retinal ganglion cells (RGCs) in tissue culture of retinal explants. METHODS Retinas from transgenic mice carrying the exogenous c-fos gene under the control of the interferon (IFN)-alpha/beta inducible Mx-promoter (Mx-c-fos), c-fos-deficient mice, and… (More)
We report a patient of a 20-year-old woman of Takayasu's arteritis and hypertensive encephalopathy. The symptoms started with headache and vomiting following status epilepticus. On arrival at the emergency room in our hospital, fever was apparent and cerebrospinal fluid examination revealed pleocytosis. After the admission, the patient presented with… (More)
