Previous studies of molluscan and mammalian neural networks have implicated potassium channels, calcium-dependent kinases and a small G-protein (Cp20) in associative memory storage. Since Alzheimer's disease is characterized by memory deficits and possible changes in PKC activation, we studied potassium channel function in AD. Patch-clamp experiments revealed the absence of a 113 pS TEA-sensitive K+ channel in fibroblasts from Alzheimer's but not control patients. These results suggest a role for potassium channel dysfunction in Alzheimer's disease.
