This increase in alpha7 nAChR expression levels within CBF neurons was inversely associated with cognitive performance. Increased alpha7 nAChR expression in CBF neurons may signal a compensatory response to maintain basocortical cholinergic activity during the onset of AD. Upregulation of the alpha7 nAChR within individual CBF neurons is also consistent with reports of increased alpha7 nAChR mRNA and protein expression levels in hippocampal neurons, astrocytes and peripheral blood leukocytes in AD [120–122]. The observed increase in alpha7 nAChR in early AD may regulate basocortical cholinergic tone through pre- and/or postsynaptic mechanisms within cholinergic NB neurons prior to their frank degeneration in the later stages of AD.
