Mt. Webster et al., POSTMORTEM BRAINS REVEAL SIMILAR BUT NOT IDENTICAL AMYLOID PRECURSOR PROTEIN-LIKE IMMUNOREACTIVITY IN ALZHEIMER COMPARED WITH OTHER DEMENTIAS, Brain research, 644(2), 1994, pp. 347-351
Concentrations of amyloid precursor protein (APP)-like immunoreactivit
y (APPLIR) have been determined by Western blotting in a soluble fract
ion and two membrane fractions of two areas of brain cortex from patie
nts with Alzheimer's disease (AD) and other dementias. There were no s
ignificant differences between AD and other cases in species with the
Kunitz protease inhibitor domain. However, the total soluble APPLIR wa
s higher in AD and it was hypothesized that this relates to cholinergi
c hypoactivity.
