It has been argued that individuals with logopenic variant primary progressive aphasia (lvPPA) have an impairment of the phonological loop, which is a component of the short-term memory (STM) system. In contrast, this type of impairment is not thought to be present in mild typical Alzheimer's disease (AD). Thus, one would predict that people with lvPPA would score significantly lower than a matched...
Anabaseine is a marine worm toxin that is a relatively non-selective nicotinic agonist, activating both muscle-type and neuronal nicotinic acetylcholine receptors (nAChR) with varying efficacy. While anabaseine has significant activity with muscle-type and neuronal α3β4 and α4β2 receptors, benzylidene anabaseine (BA) derivatives have high selectivity for the α7 receptor subtype. Two BA compounds with...
Viral vector-mediated gene transfer in brain can provide a means for gene therapy and functional studies. However, robust and persistent transgene expression in specific populations of the adult brain has been difficult to achieve. In an attempt to produce localized and persistent transduction in rat brain, we compared recombinant adeno-associated virus (rAAV) vectors incorporating either the immediate...
