Proteoglycans

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,...

Desmosomes

Desmosomes

The term desmosome derives from the Greek words "desmo" and "soma" meaning "adhesion bodies." This structure was first observed during the late 1800s and described as small, dense nodules in the epidermis. Desmosomes are button-like structures that help form an interlinked network of intermediate filaments across the cells. These junctions are essential to hold cells together under mechanical stress and to maintain tissue integrity. Desmosomes are multi-protein complexes comprising desmosomal...

Cystic Fibrosis: Pathogenesis

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, but...

Lysosomal Hydrolases

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,...

Type I Diabetes II: Pathophysiology

Type I Diabetes II: Pathophysiology

Type 1 diabetes mellitus arises from an immune-mediated destruction of pancreatic β-cells, resulting in an absolute deficiency of insulin. This process develops in genetically susceptible individuals when autoimmunity, environmental exposures, and immunologic dysregulation converge to trigger a targeted attack on the insulin-producing cells of the pancreas. The β-cells are located within the islets of Langerhans and are essential for regulating blood glucose by facilitating cellular uptake of...

Notch Signaling Pathway

Notch Signaling Pathway

The Notch signaling pathway is a major intracellular signaling pathway that is highly conserved over a broad spectrum of metazoan species. It stands unique from other intracellular signaling mechanisms in animals because notch protein itself acts as the receptor as well as the primary signaling molecule.
The Notch gene came into the limelight in 1914 after the discovery that its mutation in Drosophila melanogaster leads to a serrated (or "notched") wing margin phenotype. It was not until 1985...

Background:

Muscular dystrophies linked to aberrant α-dystroglycan glycosylation are known as dystroglycanopathies.
These disorders exhibit clinical heterogeneity, often involving central nervous system and ocular pathologies.
Defects in eight identified glycosyltransferases or their accessory proteins cause dystroglycanopathy phenotypes.

Purpose of the Study:

To review recent advancements in understanding dystroglycanopathy mechanisms.
To characterize the patient population and genetic underpinnings of these disorders.
To explore novel glycan modifications and their role in α-dystroglycan function.

Main Methods:

Systematic analysis of large patient cohorts.
Review of glycomic analyses of α-dystroglycan.
Examination of genetic defects and their correlation with clinical phenotypes.

Main Results:

Complex genotype-phenotype relationships in dystroglycanopathies have been uncovered.
A significant proportion of patients lack a genetic diagnosis, suggesting undiscovered causative genes.
Novel glycan modifications on α-dystroglycan have been identified, with pathways still under investigation.

Conclusions:

Recent studies have expanded knowledge of dystroglycanopathy pathogenesis.
Further research is needed to fully elucidate glycan synthesis, modification, and ligand-binding roles.
Continued genetic analysis is crucial for diagnosing and understanding the full spectrum of dystroglycanopathies.
