Abstract: The present invention relates to a culture of human olfactory neurons. The neurons may display a normal neuronal pathology or a pathology characteristic of a generalized central nervous system disease. The cultured neurons can be used for neurotoxicity tests, screening for therapeutic drugs and anti-viral agents, and diagnosing Alzheimer's disease.

Abstract: A method diagnosing Alzheimer's disease in a patient includes analyzing conformational changes in a band 3 protein of the patient yielding a time course of the conformational changes. One approach includes analyzing conformational changes in a band 3 protein by measuring band 3 Cl.sup.- /HCO.sub.3.sup.- exchange over time. In this approach a double exponential function is solved for two rate constant estimates by fitting the double exponential function to the time course. At least one of the rate constant estimates is used to determine whether the patient has Alzheimer's disease. A second approach includes analyzing conformational changes in a band 3 protein by measuring the emission spectrum of a stilbene bound to band 3, which emission changes in response to band 3 conformational changes. In this approach, a single exponential function is solved for a parameter by fitting the single exponential function to the time course obtained.
