mGluR5 antagonism inhibits cocaine reinforcement and relapse by elevation of extracellular glutamate in the nucleus accumbens via a CB1 receptor mechanism. [PDF]

open access: yes, 2018
Metabotropic glutamate receptor 5 (mGluR5) antagonism inhibits cocaine self-administration and reinstatement of drug-seeking behavior. However, the cellular and molecular mechanisms underlying this action are poorly understood.

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

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)-

Decision time, slow inhibition, and theta rhythm [PDF]

open access: yes, 2010
In this paper, we examine decision making in a spiking neuronal network and show that longer time constants for the inhibitory neurons can decrease the reaction times and produce theta rhythm.We analyze the mechanism and find that the spontaneous firing

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-

Cell biological mechanisms of activity-dependent synapse to nucleus translocation of CRTC1 in neurons. [PDF]

open access: yes, 2015
Previous studies have revealed a critical role for CREB-regulated transcriptional coactivator (CRTC1) in regulating neuronal gene expression during learning and memory. CRTC1 localizes to synapses but undergoes activity-dependent nuclear translocation to

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

Hypothalamic excitatory amino acid receptors mediate stress-induced tachycardia in rats [PDF]

open access: yes, 1992
The role of hypothalamic excitatory amino acid (EAA) receptors in mediating the cardiovascular response to stress was examined using conscious chronically instrumented rats.
