20120208747 | NOVEL PEPTIDE FOR AUGMENTING AND EXPRESSION OF BDNF AND PHARMACEUTICAL COMPOSITION FOR PREVENTION AND TREATMENT OF NEURODEGENERATIVE DISEASES INCLUDING ALZHEIMER'S DISEASE OR PARKINSON'S DISEASE, COMPRISING THE SAME - Disclosed are peptides for augmenting the expression of BDNF (brain-derived neurotrophic factor) and a pharmaceutical composition for the prevention and treatment of Alzheimer's disease or Parkinson's disease, comprising the same. The peptides can induce the expression of BDNF in dopamine-reactive human cells, pass easily through the blood-brain barrier thanks to their low molecular weights and are almost free of cytotoxicity. Thus, they are useful in the prevention and treatment of neuropathies such as Alzheimer's disease or Parkinson's disease. | 08-16-2012 |
