PROBLEM TO BE SOLVED: To provide a method of enhancing memory by up-regulating and down-regulating proteinkinase C for loss of memory most frequently associated with Alzheimer's disease.SOLUTION: Provided is a method of contacting proteinkinase C (PKC) with a PKC activation factor such as a large ring lactone typified by bryostatin so as to stimulate protein synthesis sufficient to fix or enhance a long-term memory.

PROBLEM TO BE SOLVED: To provide a method of diagnosing Alzheimer's disease of a patient. SOLUTION: The method includes the step of determining whether a phosphorylation level of an indicator protein in a patient's cell has abnormally rises from a basic phosphorylation level after stimulated by an activator compound, wherein the indicator protein is Erk1/2 for example and the activator compound is bradykinin for example.

PROBLEM TO BE SOLVED: To provide a medical treatment of Alzheimer's disease and a method for increasing cognitive ability.SOLUTION: Provided is a composition containing a combination of PKC activator and PKC inhibitor. Also, provided are a method for adjusting α-secretase activity, improving or increasing cognitive ability, and/or alleviating nerve degeneration in an individual having a cognitive ability decreased disease, especially Akzheimer's disease, and a method for increasing the production of non-amyloid productive soluble APP (sAPP), including activation of protein kinase C in the brain and inhibition of PKC in peripheral tissue. Incidentally, macrocyclic lactone (or bryostatin class and neristatin class) is a desirable PKC activator, and vitamin E is a desirable PKC inhibitor.
摘要:
PROBLEM TO BE SOLVED: To provide a method for reducing, in vitro, proteolysis of amyloid precursor protein, secretion of amyloid protein β, and/or phosphorylation of tau protein in a human skin fibroblast cell.SOLUTION: The method for reducing, in vitro, proteolysis of amyloid precursor protein, secretion of amyloid protein β, and/or phosphorylation of tau protein in the human skin fibroblast cell includes: bringing the cell into contact with an inhibitor of phosphorylation of MAPK effective to reduce phosphorylation to the level in the control cell, wherein the inhibitor is bisindolylmaleimide-1 (BiSM-1), protein phosphatase 1 (PP1), or 2-aminoethoxydiphenyl borate (2ABP).
摘要:
PROBLEM TO BE SOLVED: To provide methods for screening an agent for antidepressant activity.SOLUTION: The present invention provides methods for screening an agent for antidepressant activity, comprising the steps of: a) administering an agent in a pharmaceutically acceptable carrier to a test subject and administering the pharmaceutically acceptable carrier to a control subject; b) placing each of the test subjects and the control subjects into a pool of water and measuring the distance and/or duration of swimming during a testing period; and c) comparing the distances or durations of swimming of the test subjects and the control subjects, where increased distances or durations of swimming of the test subjects compared to the control subjects are indicative of antidepressant activity.
摘要:
PROBLEM TO BE SOLVED: To provide methods of slowing or reversing the loss of memory and learning comprising the steps of contacting an effective amount of a PKC activator with a protein kinase C (PKC) in a subject identified with memory loss slowing or reversing memory loss, to provide methods of stimulating cellular growth, neuronal growth, dendritic growth, dendritic spine formation, dendritic spine density, and the translocation of ELAV to proximal dendrites, and synaptic remodeling, and to also provides methods of contacting a protein kinase C (PKC) activator with a PKC activator in a manner sufficient to stimulate the synthesis of proteins sufficient to consolidate long-term memory, and to also provides methods of contacting a protein kinase C (PKC) activator with a PKC activator in a manner sufficient to downregulate PKC.SOLUTION: A pharmaceutical composition includes the PKC activity factor selected from macrocyclic lactone, benzolactam, and pyrrolidinone.
摘要:
PROBLEM TO BE SOLVED: To provide a highly efficient artificial low-density lipoprotein (LDL) carrier system for the targeted delivery of therapeutic agents across the blood-brain barrier (BBB).SOLUTION: This invention relates to artificial LDL particles comprised of three lipid elements e.g. phosphatidyl choline, fatty-acyl-cholesterol esters, and at least one apolipoprotein. The present invention further relates to compositions, methods and kits comprising artificial LDL particles for targeting drugs to and across the BBB for the prevention and treatment of brain diseases.
摘要:
PROBLEM TO BE SOLVED: To provide a composition and a method to modulate α-secretase and/or to improve cognitive ability.SOLUTION: The method includes administering PKC activator, specifically a factor for selectively activating PKCα, PKCδ and PKCε. Specifically, macrocyclic lactone, benzolactam and pyrrolidinone or a combination thereof is preferred for use with the composition.
