Nervous Tissue: Myelin01:25

Nervous Tissue: Myelin

5.9K
The myelin sheath is a multilayered lipid and protein covering that insulates the axon of a neuron, enhancing the speed of nerve impulse conduction. Axons without this sheath are referred to as unmyelinated. Two types of neuroglia, Schwann cells in the peripheral nervous system (PNS) and oligodendrocytes in the central nervous system (CNS) are responsible for producing myelin sheaths.
Schwann cells begin to form myelin sheaths around axons during fetal development. They wrap around a small...

CNS Depressants: Alcohol and Nicotine01:27

CNS Depressants: Alcohol and Nicotine

1.3K
Ethanol, a clear colorless alcohol, has been consumed by humans for millennia, but its effects on the body are far from benign. At lower doses, it induces decreased inhibitions and loquaciousness, leading to its social appeal. However, it can cause severe consequences at higher doses, such as coma and respiratory depression, due to its zero-order elimination kinetics. Chronic ethanol abuse wreaks havoc on multiple organ systems, particularly the CNS and the liver. Abrupt cessation of ethanol...

CNS Depressants: Barbiturates and Benzodiazepines

1.4K
CNS depressants include drugs from the category of barbiturates and benzodiazepines. They are valuable medications for managing anxiety disorders and insomnia. Barbiturates, once used to induce and maintain sleep, have been replaced mainly by benzodiazepines due to barbiturate's toxicity, tolerance, and overdose risks. They interact with GABAA receptors, leading to sedation at low doses and potentially coma and death at higher doses. Phenobarbital, a long-acting barbiturate, possesses...

CNS Stimulants: Psychedelic Agents01:22

CNS Stimulants: Psychedelic Agents

833
Hallucinogens, also known as psychedelic drugs, are a class of substances known for their ability to alter perception, cognition, and emotions. Despite their profound effects on the mind, these drugs are non-addictive, setting them apart from many other abused substances. The mechanism of action of these drugs lies in their impact on the 5-HT2A receptor in the brain. Upon activation, this receptor couples to Gq-type G proteins, triggering a cascade that releases intracellular calcium. This...

Chambers of the Heart01:16

Chambers of the Heart

10.6K
The human heart is a complex organ made up of four chambers: the right and left atria and the right and left ventricles. These internal chambers are separated by partitions known as the interatrial and interventricular septa. The exterior of the heart features a groove known as the coronary sulcus that demarcates the atria from the ventricles, while the anterior and posterior interventricular sulci distinguish between the two ventricles.
Deoxygenated blood from the body is received in the right...

CNS Stimulants: Cocaine, Amphetamines and Cannabinoids01:24

CNS Stimulants: Cocaine, Amphetamines and Cannabinoids

907
CNS stimulants, such as cocaine, amphetamines, and cannabinoids, have varying structures and mechanisms of action that lead to different therapeutic effects and side effects. Cocaine, with its molecular formula C17H21NO4, is a tropane alkaloid and a tertiary amino compound. It has two chemical forms: the hydrochloride salt and the "freebase." The former is in powder form, while the latter involves removing the hydrochloride salt to create a form that can be smoked. Cocaine exerts its...

Area of Science:

  • Neuroscience
  • Cell Biology
  • Biotechnology

Background:

  • In vitro myelination models are limited by high cell density and lack of cellular separation.
  • Studying myelin regeneration after injury requires compartmentalization of neural components.

  • To develop a compartmentalized microfluidic system for studying myelination.
  • To enable high-resolution live-cell imaging and molecular analysis of neuronal-myelinating cell interactions.

Main Methods:

  • Utilized microfluidics to create a compartmentalized in vitro system.
  • Enabled single-cell level live-cell imaging.
  • Facilitated large-scale molecular analyses (e.g., RNA sequencing) on separated cell populations.

Main Results:

  • Demonstrated a method for dynamic observation of neuron-myelinating cell interactions.
  • Allowed for the collection of pure or highly enriched neuronal and myelinating cell samples.
  • Enabled detailed study of myelination dynamics and molecular changes.

Conclusions:

  • The microfluidic approach overcomes limitations of traditional models for myelination research.
  • Provides a powerful tool for mechanistic studies of myelin development, maintenance, and regeneration.
  • Facilitates advanced analyses like transcriptomics on distinct neural cell types.
