Insights

Mucopolysaccharidoses (MPS) involve undegraded glycosaminoglycans triggering inflammation and organ damage. Understanding these cellular processes reveals new therapeutic targets for MPS patients.

Area of Science:

  • Biochemistry
  • Cell Biology
  • Pathophysiology

Background:

  • Mucopolysaccharidoses (MPS) are genetic disorders characterized by the accumulation of undegraded glycosaminoglycans (GAGs).
  • This accumulation leads to cellular dysfunction and progressive damage across multiple organ systems.
  • Current therapies for MPS have limitations in addressing the full spectrum of disease pathology.

Purpose of the Study:

  • To review current knowledge on the role of GAGs in MPS pathophysiology.
  • To elucidate the complex pathogenetic cascades initiated by undegraded GAGs.
  • To identify novel therapeutic targets for MPS treatment.

Main Methods:

  • Literature review of existing research on MPS and GAG metabolism.
  • Analysis of cellular mechanisms involved in MPS pathogenesis.
  • Synthesis of information on signaling pathways, cellular transport, and homeostasis.

Main Results:

  • Undegraded GAGs act as potent stimulants for secondary pathogenetic events.
  • These events include substrate accumulation, membrane abnormalities, impaired vesicular transport, disrupted autophagy, aberrant intracellular signaling, calcium dysregulation, and oxidative stress.
  • The review details the complex interplay of these factors in MPS.

Conclusions:

  • Understanding the cellular basis of MPS pathophysiology is crucial for improving treatment strategies.
  • Identifying new therapeutic targets based on these cellular processes can lead to more effective therapies for MPS patients.
  • This knowledge can help overcome limitations of current MPS treatments.

Proteoglycans01:05

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,...

Lysosomal Hydrolases01:22

Lysosomal Hydrolases

Lysosomes are the site for the degradation of macromolecules and biological polymers released during membrane trafficking events such as secretory, endocytic, autophagic, and phagocytic pathways. The membrane-enclosed area of the lysosome, called the lumen, contains hydrolytic enzymes active in an acidic environment. These acid hydrolases are functional at a pH between 4.5 and 5 and are involved in cellular processes such as cell signaling, energy metabolism, restoration of the plasma membrane,...

Cystic Fibrosis: Pathogenesis

Cystic fibrosis (CF), an autosomal recessive disorder, significantly affects the function of exocrine glands. This genetically inherited disease is characterized by the production of thick and sticky mucus, which can severely affect various organs and systems in the body.
CF is primarily caused by a genetic mutation in a chromosome 7 gene coding for the cystic fibrosis transmembrane conductance regulator (CFTR) protein. The most common gene mutation leading to CF is the ΔF508 mutation,...

Glycosaminoglycans01:23

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.

Oligosaccharide Assembly01:24

Oligosaccharide Assembly

Protein glycosylation starts in the ER lumen and continues in the Golgi apparatus. Glycosyltransferases catalyze the addition of sugar molecules or glycosylation of proteins. Usually, these enzymes add sugars to the hydroxyl groups of selected serine or threonine residues to form O-linked glycans or the amino groups of asparagine residues to form N-linked glycans. Different positions on the same polypeptide chain can contain differently linked glycans.
Multiple sugar molecules that may or may...

Cohesins02:20

Cohesins

Cohesin protein complexes are a molecular glue that holds two sister chromatids together. They play an important role both in mitosis and meiosis. In mitosis, all cohesin complexes present on the chromosomes are removed before the start of the anaphase stage.
Cohesin complexes in Meiotic Division
Meiosis involves two distinct rounds of chromosomal segregation and cell divisions— Meiosis I followed by Meiosis II – producing four daughter cells. Meiosis I includes the separation of...
