Extracellular Chaperones Modulate The Effects Of Alzheimer's Patient Cerebrospinal Fluid On A Beta(1-42) Toxicity And Uptake , Justin J. Yerbury, Mark R. Wilson

Mark R Wilson

Alzheimer's disease is characterised by the inappropriate death of brain cells and accumulation of the A beta peptide in the brain. Thus, it is possible that there are fundamental differences between Alzheimer's disease patients and healthy individuals in their abilities to clear A beta from brain fluid and to protect neurons from A beta toxicity. In the present study, we examined (1) the cytotoxicity of Alzheimer's disease cerebrospinal fluid (CSF) compared to control CSF, (2) the ability of Alzheimer's disease and control CSF to protect cells from A beta toxicity and to promote cell-mediated clearance of A beta and lastly …
