Abstract:
Alzheimers disease is a progressive neurodegeneration disorder that is characterised by the accumulation of ? amyloid deposits and neurofibrillary tangles. It has been long assumed that the disrupted interneuronal communication that occurs in AD brain does not involve widespread changes in postsynaptic receptor function. However, recent evidence suggests that both the neurotransmitter receptor/G protein modulated adenyl cyclase and the phosphatidylinositol hydrolysis signal transduction cascades are disrupted in AD. Such disruption in AD may provide a reason for the relative lack of success of neurotransmitter replacement therapies for the disorder. Moreover it can direct drug research and development for AD treatment.
