  • Cell tests for Alzheimer's disease
    Publication number: 20030108956
    Abstract: The present invention provides methods for the diagnosis of Alzheimer's disease using human cells. Specifically, one method detects differences between potassium channels in cells from Alzheimer's patient and normal donors, and differences in intracellular calcium concentrations between Alzheimer's and normal cells in response to chemicals known to increase intracellular calcium levels. Other methods detect differences between the memory associated GTP binding Cp20 protein levels between Alzheimer's and normal cells.
    Type: Application
    Filed: August 16, 2002
    Publication date: June 12, 2003
    Inventors: Daniel L. Alkon, Rene Etcheberrigaray, Christopher S. Kim, Yi-Fan Han, Tom J. Nelson
  • Cell tests and diagnostic index for alzheimer's disease
    Publication number: 20020098520
    Abstract: The present invention provides methods for the diagnosis of Alzheimer's disease using human cells. Specifically, one method detects differences between potassium channels in cells from Alzheimer's patient and normal donors, and differences in intracellular calcium concentrations between Alzheimer's and normal cells in response to chemicals known to increase intracellular calcium levels. Other methods detect differences between the memory associated GTP binding Cp20 protein levels between Alzheimer's and normal cells. In addition a diagnostic index for improved assessment between Alzheimer's and non Alzheimer's cells is provided.
