Accumulating evidence suggests that butyrylcholinesterase (BuChE) plays an important role in the progression of cognitive deficits and Alzheimer-type pathology in dementia patients. We examined the relationship between the K variant of BuChE and the severity of deposits of amyloid (Aβ(1-42)) and phosphorylated tau in the temporal cortex (BA36) of 30 prospectively studied autopsy-diagnosed dementia ( Alzheimer's disease and dementia with Lewy bodies) patients. There was 42% less phosphorylated tau in BA36 in cases with ≥ 1 K compared with those with wild-type BuChE alleles (t = 2.2, p = 0.039), but no difference in the extent of Aβ(1-42) deposition. BuChE may play this role in the phosphorylation of tau, relevant to therapeutic inhibition of the enzyme. Copyright (C) 2005 S. Karger AG, Basel.
