Characterization of a novel processing pathway for Alzheimer's amyloid beta precursor protein.

abstract：:The beta-carbolines, methyl-beta-carboline-3-carboxylate (beta-CCM) and 6,7-dimethoxy-4-ethyl-beta-carboline-3-carboxylate (DMCM) are known to have pharmacological properties opposite to those of agonistic benzodiazepines. Convulsions induced by these drugs lead to differential patterns, such as clonus, myoclonic or t...
