Insights

Glycosaminoglycans (GAGs) bind pathogens in vitro, but their in vivo role in infectious disease is unclear. This study uses mouse models to investigate GAGs' function in bacterial lung and corneal infections.

Area of Science:

  • Microbiology
  • Immunology
  • Biochemistry

Background:

  • Glycosaminoglycans (GAGs) bind diverse microbial pathogens in vitro.
  • GAGs are hypothesized to promote pathogenesis by aiding pathogen attachment, invasion, or immune evasion.
  • The in vivo role and pathophysiological significance of GAGs in infectious diseases remain largely unknown.

Purpose of the Study:

  • To directly investigate the role of GAGs in vivo during infectious diseases.
  • To establish the importance and specificity of GAGs in pathogenesis.
  • To define essential GAG structural features and identify pathogenic biological activities.

Main Methods:

  • Development of mouse models for bacterial lung and corneal infections.
  • Direct investigation of GAGs' role in vivo.
  • Experimental strategies to determine GAG specificity and structural requirements.

Main Results:

  • Methods established to directly investigate GAGs in vivo.
  • Experimental strategy designed to elucidate GAG functions in pathogenesis.
  • Focus on defining structural features and biological activities of GAGs.

Conclusions:

  • This study lays the groundwork for understanding GAGs' in vivo role in infection.
  • The developed methods will enable detailed investigation into GAG-mediated pathogenesis.
  • Future research will define specific GAG structures and activities crucial for infectious disease progression.

Glycosaminoglycans

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.

Proteoglycans

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,...

Matrix Proteoglycans and Glycoproteins

Proteoglycans are extensively glycosylated proteins, commonly found in the extracellular matrix, interwoven with collagen fibers. Hyaline cartilage, the most common type of cartilage in the body, consists of short and dispersed collagen fibers associated with large amounts of proteoglycans. These proteoglycans have long negative charges that attract cations, which in turn attract water molecules. This influx of ions and water molecules swells up the proteoglycan like a water-soaked gel that can...

Protein Glycosylation01:25

Protein Glycosylation

Glycosylation, the most common post-translational modification for proteins, serves diverse functions. Adding sugars to proteins makes the proteins more resistant to proteolytic digestion. Glycosylated proteins can act as markers and receptors to promote cell-cell adhesion. Additionally, they have many essential quality control functions in the cell, such as correct protein folding and facilitating transport of misfolded proteins to the cytosol, which can be degraded.
Glycosylation occurs in...
