Influence of glyphosate and its metabolite aminomethylphosphonic acid on aquatic plants in different ecological niches

open access: yesEcotoxicology and Environmental Safety, 2022
Glyphosate and its metabolite aminomethylphosphonic acid (AMPA) draw great concern due to their potential threat to aquatic ecosystems. The individual and combined effects of glyphosate and AMPA on aquatic plants in different ecological niches need to be

AMPA receptor trafficking and learning [PDF]

open access: yesEuropean Journal of Neuroscience, 2010
AbstractIn the last few years it has become clear that AMPA‐type glutamate neurotransmitter receptors are rapidly transported into and out of synapses to strengthen or weaken their function. The remarkable dynamics of AMPA receptor (AMPAR) synaptic localization provides a compelling mechanism for understanding the cellular basis of learning and memory,

The adhesion modulation protein, AmpA localizes to an endocytic compartment and influences substrate adhesion, actin polymerization and endocytosis in vegetative Dictyostelium cells

open access: yesBMC Cell Biology, 2012
Background AmpA is a secreted 24Kd protein that has pleiotropic effects on Dictyostelium development. Null mutants delay development at the mound stage with cells adhering too tightly to the substrate.

Exogenous AMPA downregulates gamma-frequency network oscillation in CA3 of rat hippocampal slices

open access: yesScientific Reports, 2023
Pharmacologically-induced persistent hippocampal γ oscillation in area CA3 requires activation of α-Amino-3-hydroxy-5-methyl-4-isoxazolepropionate receptors (AMPARs). However, we demonstrated that exogenous AMPA dose-dependently inhibited carbachol (CCH)-

Copine-6 is a Ca2+ sensor for activity-induced AMPA receptor exocytosis

open access: yesCell Reports, 2023
Summary: The recruitment of synaptic α-amino-3-hydroxy-5-methyl-4-isoxazole propionic acid (AMPA) receptors underlies the strengthening of neuronal connectivity during learning and memory. This process is triggered by N-methyl-D-aspartate (NMDA) receptor-

Acid-Sensing Ion Channels Activated by Evoked Released Protons Modulate Synaptic Transmission at the Mouse Calyx of Held Synapse [PDF]

open access: yes, 2017
Acid-sensing ion channels (ASICs) regulate synaptic activities and play important roles in neurodegenerative diseases. We found that these channels can be activated in neurons of the medial nucleus of the trapezoid body (MNTB) of the auditory system in ...

Progesterone monitoring and gestation length in Amazonian manatees (Trichechus inunguis)

open access: yesTheriogenology Wild
Knowledge of pregnancy length and the physiological parameters during pregnancy is an important tool for pregnancy diagnosis in free-ranging and captive individuals and for the correct husbandry of captive pregnant females. Therefore, this study aimed to

AMPA-ergic regulation of amyloid-β levels in an Alzheimer’s disease mouse model

open access: yesMolecular Neurodegeneration, 2018
Background Extracellular aggregation of the amyloid-β (Aβ) peptide into toxic multimers is a key event in Alzheimer’s disease (AD) pathogenesis. Aβ aggregation is concentration-dependent, with higher concentrations of Aβ much more likely to form toxic ...
