Insights

Marfan syndrome (MFS), a common inherited connective tissue disorder, severely impacts the cardiovascular system due to FBN1 gene mutations. Further research is needed to understand fibrillin-1

Area of Science:

  • Genetics and Molecular Biology
  • Cardiovascular Medicine
  • Connective Tissue Disorders

Background:

  • Marfan syndrome (MFS) is a prevalent inherited connective tissue disorder.
  • It significantly affects the cardiovascular system.
  • Mutations in the fibrillin-1 (FBN1) gene are linked to MFS, ectopia lentis, and neonatal MFS.

Purpose of the Study:

  • To review the current understanding of Marfan syndrome pathogenesis.
  • To highlight diagnostic challenges in MFS.
  • To emphasize the need for further research into fibrillin-1's role.

Main Methods:

  • Review of recent molecular studies on MFS.
  • Analysis of fibrillin-1's function in connective tissue.
  • Discussion of experimental systems for studying MFS.

Main Results:

  • Fibrillin-1 is a key component of elastic fiber microfibrils.
  • Molecular studies have advanced understanding of MFS pathogenesis.
  • Diagnostic difficulties in MFS persist.

Conclusions:

  • Targeted therapy for MFS requires a deeper understanding of fibrillin-1's function.
  • Further investigation using diverse experimental systems is crucial.
  • Improved diagnostic strategies are needed.

Fibril-associated Collagen01:11

Fibril-associated Collagen

Fibril-associated collagens are a type of collagens present in the extracellular matrix with interrupted triple helices or FACIT (Fibril-associated collagens interrupted triple-helices). FACIT help connect and attach the collagen fibrils with each other as well as with other proteins of the extracellular matrix.
For example, the type II collagen fibrils in cartilage have covalently bound type IX fibril-associated collagens at regular intervals. Other types of fibril-associated collagens are...
Clot Retraction and Fibrinolysis01:16

Clot Retraction and Fibrinolysis

After a fibrin clot is formed, the next step is clot retraction, a vital process facilitated by platelet contractile proteins, such as actin and myosin. These proteins pull the fibrin strands closer together and condense the clot. This action reduces the size of the clot, creating a smaller, denser structure that effectively seals off the damaged vessel. Clot retraction consolidates the clot and helps with wound healing by bringing the edges of the damaged blood vessel closer together.
Structural Protein Function01:56

Structural Protein Function

Structural proteins are a category of proteins responsible for functions ranging from cell shape and movement to providing support to major structures such as bones, cartilage, hair, and muscles. This group includes proteins such as collagen, actin, myosin, and keratin.
Collagen, the most abundant protein in mammals, is found throughout the body. In connective tissue, such as skin, ligaments, and tendons, it provides tensile strength and elasticity.  In bones and teeth, it mineralizes to form...
Fibrous Proteins00:55

Fibrous Proteins

Fibrous proteins are either long and narrow proteins or assemble to form long and thin structures. They contain repetitive units and usually consist of either alpha helices or beta sheets and, in rare cases, a mix of both. The amino acids in the primary structure often consist of repeating amino acid sequences. The role of fibrous proteins is primarily structural. Many are located in the extracellular matrix and are present in connective tissues to impart strength and joint mobility. They are...
Amyloid Fibrils03:03

Amyloid Fibrils

Amyloid fibrils are aggregates of misfolded proteins.  Under most circumstances, misfolded proteins are either refolded by chaperone proteins or degraded by the proteasome. However, in the case of a mutation or a disease, these proteins can accumulate to form large clusters and often further assemble to form elongated fibers, called fibrils. 
Amyloid deposits were observed as early as 1639 in the liver and the spleen.   In 1854, Rudolph Virchow performed iodine staining, normally used to...
Types of Intermediate Filaments01:31

Types of Intermediate Filaments

The intermediate filaments are an essential component of the cytoskeleton. Presently six types of intermediate filament have been identified. Type I and II are acidic and basic keratin proteins. Type III is of mesodermal origin and comprises four proteins: vimentin, desmin, glial fibrillary acidic protein (GFAP), and peripherin. Vimentin is commonly found in mesenchymal cells, desmin in muscle cells, GFAP in astrocytes, while peripherin is found in peripheral nervous system neurons (PNS). Type...
