Dopaminergic Neurotransmission in Patients With Parkinson's Disease and Impulse Control Disorders: A Systematic Review and Meta-Analysis of PET and SPECT Studies

open access: yesFrontiers in Neurology, 2018
Background: Around 30% Parkinson's disease (PD) patients develop impulse control disorders (ICDs) to D2/3 dopamine agonists and, to a lesser extent, levodopa.

Nitrate transporters and peptide transporters

open access: yesFEBS Letters, 2007
In higher plants, two types of nitrate transporters, NRT1 and NRT2, have been identified. In Arabidopsis, there are 53 NRT1 genes and 7 NRT2 genes. NRT2 are high‐affinity nitrate transporters, while most members of the NRT1 family are low‐affinity nitrate transporters.

Cell-Based Radiotracer Binding and Uptake Inhibition Assays: A Comparison of In Vitro Methods to Assess the Potency of Drugs That Target Monoamine Transporters

open access: yesFrontiers in Pharmacology, 2020
High-affinity monoamine transporters are targets for prescribed medications and stimulant drugs of abuse. Therefore, assessing monoamine transporter activity for candidate medications and newly-emerging drugs of abuse provides essential information for ...

Transport Dynamics in a Glutamate Transporter Homologue [PDF]

open access: yesBiophysical Journal, 2013
Glutamate transporters are integral membrane proteins that catalyse neurotransmitter uptake from the synaptic cleft into the cytoplasm of glial cells and neurons. Their mechanism of action involves transitions between extracellular (outward)-facing and intracellular (inward)-facing conformations, whereby substrate binding sites become accessible to ...

Structural basis for mammalian nucleotide sugar transport

open access: yeseLife, 2019
Nucleotide-sugar transporters (NSTs) are critical components of the cellular glycosylation machinery. They transport nucleotide-sugar conjugates into the Golgi lumen, where they are used for the glycosylation of proteins and lipids, and they then ...

Neuronal glutamate transporters control reciprocal inhibition and gain modulation in D1 medium spiny neurons

open access: yeseLife, 2023
Understanding the function of glutamate transporters has broad implications for explaining how neurons integrate information and relay it through complex neuronal circuits.

The transport fo self-propelled particles confined in 2D smooth corrugated channel [PDF]

open access: yesarXiv, 2022
Directed transport of self-propelled ellipsoidal particles confined in a smooth corrugated channel with asymmetric potential and Gaussian colored noise is investigated. Effects of the channel, potential and colored noise on the system are discussed. Large x axis noise intensity inhibits the transport.

Response and Tolerance of Macleaya cordata to Excess Zinc Based on Transcriptome and Proteome Patterns

open access: yesPlants, 2023
Macleaya cordata is a dominant plant of mine tailings and a zinc (Zn) accumulator with high Zn tolerance. In this study, M. cordata seedlings cultured in Hoagland solution were treated with 200 μmol·L−1 of Zn for 1 day or 7 days, and then, their leaves ...
