Ligand-Gated Ion Channel Receptor: Gating Mechanism01:30

Ligand-Gated Ion Channel Receptor: Gating Mechanism

3.1K
Ligand-gated ion channels are transmembrane proteins that play a vital role in intercellular communication and functions of the nervous system. They allow the influx of ions across the membrane once the neurotransmitter binds, allowing the subsequent transmission of electrical excitation across the neurons. Other ligand-gated ion channels, like the γ-aminobutyric acid (GABA) receptor, permit anions like chloride into the cells on the binding of the GABA molecule. Their entry into the cell...

Antiepileptic Drugs: Glutamate Antagonists

626
Glutamate is a fundamental neurotransmitter in the central nervous system, playing a vital role in neuronal communication and various cognitive processes. Glutamate stands as the principal excitatory neurotransmitter in the brain. Its presence is crucial for the communication between neurons, underpinning essential processes such as synaptic transmission, neuronal excitability, and plasticity. These functions are vital for higher-order cognitive processes, including learning and memory. The...

Long-term Potentiation01:35

Long-term Potentiation

56.7K
Long-term potentiation, or LTP, is one of the ways by which synaptic plasticity—changes in the strength of chemical synapses—can occur in the brain. LTP is the process of synaptic strengthening that occurs over time between pre- and postsynaptic neuronal connections. The synaptic strengthening of LTP works in opposition to the synaptic weakening of long-term depression (LTD) and together are the main mechanisms that underlie learning and memory.

Enzyme-linked Receptors01:00

Enzyme-linked Receptors

81.6K
Enzyme-linked receptors are proteins that act as both receptor and enzyme, activating multiple intracellular signals. This is a large group of receptors that include the receptor tyrosine kinase (RTK) family. Many growth factors and hormones bind to and activate the RTKs.
Neurotrophin (NT) receptors are a family of RTKs, including trkA, trkB, and trkC (tropomyosin-related kinase) receptors. TrkA is specific for nerve growth factor (NGF), neurotrophin-6, and neurotrophin-7. TrkB binds...

Area of Science:

  • Neuroscience
  • Developmental Biology

Background:

  • Brain development involves synaptogenesis, migration, and synaptic plasticity.
  • These processes are regulated by neurotransmitter receptors, notably glutamate receptors.
  • The expression and function of glutamate receptors change significantly during fetal and neonatal development.

Purpose of the Study:

  • To review the role of glutamate receptors in neonatal brain development.
  • To examine how developmental stage influences glutamate receptor expression and distribution.
  • To explore the impact of environmental factors on glutamate receptor regulation.

Main Methods:

  • This is a review article, synthesizing existing research.
  • Analysis of studies focusing on glutamate receptor expression during development.
  • Examination of literature on environmental influences on neurodevelopment.

Main Results:

  • Glutamate receptor expression and cellular distribution in the neonatal brain are stage-dependent.
  • Environmental factors like stress and alcohol can disrupt glutamate receptor development.
  • Developmental stage correlates with ongoing functional activities in the neonatal brain.

Conclusions:

  • The developmental stage critically determines glutamate receptor characteristics in the neonatal brain.
  • Dysregulation of glutamate receptors due to environmental factors can lead to developmental neuropathologies.
  • These neuropathologies may have long-term consequences for an individual's development and function.
