In vitro evaluation of isatin-pyridine oxime hybrids as potential acetylcholinesterase inhibitors for nerve agent prophylaxis

Author(s): Silva MCJD; Pinto AMV; Balthar MA; Correa ABA; Bhattacharyya D; Simas ABC; Kuca K; Forgione P; França TCC; Cavalcante SFA; Kitagawa DAS;

Given the recent deployment of nerve agents as a method of warfare and in targeted assassinations, the development of robust, broad-spectrum medical countermeasures is essential. Our research group has synthesized isatin-pyridine oxime hybrids that have previously demonstrated the ability to resc ...

Modulatory effects of M3 muscarinic acetylcholine receptor on inflammatory profiles of human memory T helper cells

Author(s): Gholizadeh F; Hajiaghayi M; Choi JS; Little SR; Rahbari N; Kargar M; Brotto K; Han E; Shih SCC; Darlington PJ;

Memory T helper (Th) cells, generated in response to immunogenic challenges, are crucial in orchestrating adaptive immune responses. Acetylcholine (ACh), a key neurotransmitter of the parasympathetic nervous system, modulates immune function via muscarinic ACh receptors (mAChRs). This study inves ...

Inhibiting amyloid beta (1-42) peptide-induced mitochondrial dysfunction prevents the degradation of synaptic proteins in the entorhinal cortex

Author(s): Olajide OJ; La Rue C; Bergdahl A; Chapman CA;

Increasing evidence suggests that mitochondrial dysfunction and aberrant release of mitochondrial reactive oxygen species (ROS) play crucial roles in early synaptic perturbations and neuropathology that drive memory deficits in Alzheimer's disease (AD). We recently showed that solubilized human amyloid beta peptide 1-42 (hAß1-42) causes rapid alterati ...

Normal cognition in Parkinson's disease may involve hippocampal cholinergic compensation: An exploratory PET imaging study with [(18)F]-FEOBV

Author(s): Legault-Denis C; Aghourian M; Soucy JP; Rosa-Neto P; Dagher A; Aumont E; Wickens R; Bedard MA;

Background: Severe cholinergic degeneration is known to occur in Parkinson's disease (PD) and is thought to play a primary role in the cognitive decline associated with this disease. Although cholinergic losses occur in all patients with PD, cognitive performance remains normal for many of th ...
