Nervous Tissue: Glial Cells

12.7K
Glia, or neuroglia, are vital support cells that assist neurons in their functions. The term "glia" originates from the Greek word for "glue," reflecting their role in holding the nervous system together. These cells can be categorized into six types: four in the central nervous system (CNS) and two in the peripheral nervous system (PNS).
The CNS glial cell includes the astrocytes, the oligodendrocytes, the microglia, and the ependymal cells.
Astrocytes are star-shaped glial...

Membrane Lipids

35.7K
Lipids are an essential component of all biological membranes. The average lipid content in mammalian membranes is 50%, though it can be as low as 20% in the inner mitochondrial membrane or as high as 80% in the myelin sheath present around the nerve cells.
Phosphatidylcholine, phosphatidylethanolamine, phosphatidylserine, and sphingomyelin are the most common phospholipids present in mammalian membranes. At physiological pH, phosphatidylserine is negatively charged, while the other three...

Nervous Tissue: Myelin

11.8K
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...

Proteoglycans01:05

Proteoglycans

5.3K
Glycans, a class of complex heterogeneous molecules, can be covalently attached to proteins to form glycosylated proteins that regulate various physiological and pathological processes. Glycosylated proteins or glycoproteins comprise N-linked and O-linked oligosaccharides. O-glycosylation is the most common type of protein glycosylation. Here, glycans attach to the oxygen atom of the hydroxyl groups of Serine or Threonine residues. O-linked glycosylation occurs later in protein processing,...

Glycosaminoglycans01:23

Glycosaminoglycans

8.0K
Glycosaminoglycans (GAGs), also known as mucopolysaccharides, are long and linear polymers comprising of specific repeating disaccharides - the amino sugar that can be N-acetylglucosamine or N-acetylgalactosamine, and a uronic acid that is usually glucuronic acid or iduronic acid.
GAGS are found in the extracellular matrix of vertebrates, invertebrates, and bacteria. Due to their polar nature they attract water, and serve as excellent lubricants or shock absorbers in an animal body.
Hyaluronic...

Area of Science:

  • Neuroscience
  • Cell Biology
  • Biochemistry

Background:

  • Lipid rafts are key signaling platforms enriched in glycosphingolipids (GSLs).
  • Gangliosides, a major GSL class in brain grey matter, influence neuronal function via cell signaling modulation.
  • Increased lifespan raises dementia prevalence, necessitating research into aging-related cellular changes.

Purpose of the Study:

  • To review ganglioside expression changes during brain development.
  • To examine the specific effects of gangliosides on neuronal function.
  • To explore the potential role of gangliosides in dementing diseases.

Main Methods:

  • Literature review of studies on ganglioside expression and function.
  • Analysis of data linking GSL composition to lipid raft function.
  • Correlation of observed ganglioside changes with dementia phenotypes.

Main Results:

  • Ganglioside expression patterns are dynamic during brain development.
  • Gangliosides significantly impact neuronal signaling pathways.
  • Alterations in ganglioside profiles are observed in the context of aging and dementia.

Conclusions:

  • Changes in ganglioside expression are integral to brain development and function.
  • Dysregulation of gangliosides within lipid rafts may underlie dementia pathogenesis.
  • Further investigation into GSLs offers potential therapeutic targets for dementia.
