Abstract:
본발병은망막에존재하는 ON 또는 OFF 이극세포에선택적으로광유전자를발현시키기위한방법으로, 구체적으로는 ON 이극세포에특이적으로발현하는프로모터, 제1 표적유전자및 Cre 유전자를포함하는제1 벡터및 ON/OFF 이극세포에발현하는프로모터, 제2 표적유전자및 loxP 서열을포함하는제2 벡터를포함하는이극세포에서선택적유전자발현용키트및 이를이극세포에도입하여이극세포에서유전자를선택적으로발현시키는방법에관한것이다. 일구체예에서개시된바업을이용할경우광수용체가없을경우에도이극세포에서빛을감지할수 있으며, 이러한경우광수용체가사멸하는안질환을갖는환자에게효과적인치료법을제공할수 있다.
Abstract:
The present invention relates to a mechanism of the glutamate release from astrocytes and, more specifically, to a rapid release mechanism of glutamate and a slow release mechanism of glutamate, mediated with a channel. The present invention reveals the mechanism of the glutamate release from astrocytes, thereby enabling users to practically use the mechanism for developing a nerve cell protection technology and a neuro-transmission promoting technology through controlling astroglial cells.
Abstract:
PURPOSE: A phenoxypropanol derivative is provided to effectively suppress T-type calcium channel or TWIK-related K+ (TREK)-1 channel, thereby treating various diseases caused by the activation of the channels. CONSTITUTION: A phenoxypropanol derivative of chemical formula I or a racemic body, a pharmaceutically acceptable salt, a solvate, or a hydrate thereof is provided. A pharmaceutical composition for preventing or treating diseases related to T-type calcium channel or TREK-1 channel, selected among Parkinson's disease, Alzheimer's disease, schizophrenia, sleep disorder, epilepsy, pain, hypertension, arrhythmia, ventricular hypertrophy, angina pectoris, heart failure, myocardial infarction, cancer, hypoxia, cerebral ischemia, alkalemia, and depression contains the phenoxypropanol derivative, the racemic body, the pharmaceutically acceptable salt, the solvate, or the hydrate as an active ingredient. A method for suppressing T-type calcium channel or TREK-1 channel comprises the steps of: preparing a biological sample from an organ; and applying the phenoxypropanol derivative, the racemic body, the pharmaceutically acceptable salt, the solvate, or the hydrate to the biological sample.
