Meredith E. Jackrel,Morgan E. DeSantis,Bryan A. Martinez,Laura M. Castellano,Rachel M. Stewart,Kim A. Caldwell,Guy A. Caldwell,James Shorter +7 more
TL;DR: It is established that disease-associated aggregates and amyloid are tractable targets and that enhanced disaggregases can restore proteostasis and mitigate neurodegeneration.
Journal ArticleDOI
Nicotinic Partial Agonists, Varenicline and Sazetidine-A, have Differential Effects on Affective Behavior.
TL;DR: The results suggest that the partial agonists varenicline and sazetidine-A may have diverse therapeutic benefits in affective disorders.
Journal ArticleDOI
Parallel anxiolytic-like effects and upregulation of neuronal nicotinic acetylcholine receptors following chronic nicotine and varenicline.
TL;DR: Varenicline has been shown to be an efficacious smoking cessation aid, with a proposed mechanism of action that includes modulation of dopamine release in reward areas of the brain that suggests receptor upregulation as a mechanism for its efficacy as a smoking cessation therapy.
Journal ArticleDOI
Structural basis for substrate gripping and translocation by the ClpB AAA+ disaggregase.
Alexandrea N. Rizo,Alexandrea N. Rizo,JiaBei Lin,Stephanie N. Gates,Eric Tse,Stephen M. Bart,Laura M. Castellano,Frank DiMaio,James Shorter,Daniel R. Southworth +9 more
TL;DR: NBD conformations at the seam interface reveal how ATP hydrolysis-driven substrate disengagement and re-binding are precisely tuned to drive a directional, stepwise translocation cycle.
Journal ArticleDOI
