Abstract
In an attempt to find a reliable peripheral marker of Alzheimer's disease (AD), pieces of olfactory mucosa were removed by biopsy from 11 patients with probable AD and from eight control patients. The samples were analysed immunocytochemically using monoclonal and polyclonal antibodies. The olfactory and peripheral neurons of the olfactory mucosa in both AD and control patients typically exhibited immunoreactivity to neurofilament (NF) triplet proteins, including both phosphorylated and non-phosphorylated epitopes, as well as to synaptophysin, but lacked reactivity to other intermediate filament proteins, microtubule-associated protein 2 and tau. Our results do not support the recent findings suggesting the lack of NF proteins in olfactory neurons or the preferential phosphorylated status of NF proteins in olfactory neurons solely in AD.
