Stability in the Face of Change: Lifelong Experience-Dependent Plasticity in the Sensory Cortex

open access: yesFrontiers in Cellular Neuroscience, 2020
Plasticity is a fundamental property of the nervous system that enables its adaptations to the ever-changing environment. Heightened plasticity typical for developing circuits facilitates their robust experience-dependent functional maturation.

Exercise enhances motor skill learning by neurotransmitter switching in the adult midbrain. [PDF]

open access: yes, 2020
Physical exercise promotes motor skill learning in normal individuals and those with neurological disorders but its mechanism of action is unclear. We find that one week of voluntary wheel running enhances the acquisition of motor skills in normal adult ...

Serotonergic Modulators in Alzheimer's Disease: A Hope in the Hopeless Condition

open access: yesChemistry &Biodiversity, EarlyView.
ABSTRACT Alzheimer's disease (AD) is the main cause of dementia worldwide. AD is a progressive brain neurodegenerative disease due to genetic and environmental factors that induce a progressive accumulation of intracellular hyperphosphorylated tau protein and extracellular amyloid protein (Aβ).

Alzheimer’s Disease as a Membrane Disorder: Spatial Cross-Talk Among Beta-Amyloid Peptides, Nicotinic Acetylcholine Receptors and Lipid Rafts [PDF]

open access: yes, 2019
Biological membranes show lateral and transverse asymmetric lipid distribution. Cholesterol (Chol) localizes in both hemilayers, but in the external one it is mostly condensed in lipid-ordered microdomains (raft domains), together with saturated ...

Chemical Characterization, Antioxidant, and Anticholinesterase Activities of Libidibia ferrea (Mart. Ex Tul.) L.P.Queiroz and In Silico Studies with the Acetylcholinesterase Enzyme

open access: yesChemistry &Biodiversity, EarlyView.
ABSTRACT Libidibia ferrea is used in many parts of Brazil for a variety of conditions, such as inflammation, respiratory disorders, muscle pain, and gastrointestinal problems. This study evaluated the chemistry and antioxidant and acetylcholinesterase (AChE) inhibitory activities of L. ferrea extracts. Hydroethanolic extracts of leaves (ELLF) and bark (

Single copy/knock-in models of ALS SOD1 in C. elegans suggest loss and gain of function have different contributions to cholinergic and glutamatergic neurodegeneration [PDF]

open access: yes, 2018
Mutations in Cu/Zn superoxide dismutase 1 (SOD1) lead to Amyotrophic Lateral Sclerosis (ALS), a neurodegenerative disease that disproportionately affects glutamatergic and cholinergic motor neurons.

The Molecular Properties of Honey Bee Acetylcholinesterase Reveal Opportunities to Avoid Off‐Target Effects in Insecticide Discovery

open access: yesChemistry – A European Journal, EarlyView.
The structure, dynamics, and kinetics of the essential enzyme acetylcholinesterase (AChE) of honey bee have been studied and compared to AChEs in mosquitoes and mammalians. Profiling of the active sites with selected substrates and AChE inhibitors revealed dramatic differences between the species.
