Insights

Adhesion molecules are crucial in collagen diseases, mediating cell interactions and driving disease progression. Understanding their role in leukocyte recruitment and tissue damage is key to developing targeted therapies for these autoimmune conditions.

Area of Science:

  • Immunology
  • Cell Biology
  • Rheumatology

Context:

  • Collagen diseases involve complex cell-cell and cell-extracellular matrix interactions.
  • Adhesion molecules are critical mediators of these interactions in various autoimmune and inflammatory conditions.

Purpose:

  • To elucidate the specific roles of adhesion molecules in the pathogenesis of collagen diseases.
  • To highlight the involvement of adhesion molecules in leukocyte recruitment, pannus formation, fibrosis, and vasculitis.

Summary:

  • Adhesion molecules on endothelial cells facilitate leukocyte recruitment in collagen diseases.
  • In rheumatoid arthritis (RA), they contribute to chondrocyte destruction via pannus formation.
  • In progressive systemic sclerosis (PSS), they promote fibrosis by interacting with monocytes and collagen fibrils.
  • Their roles in myositis, systemic lupus erythematosus (SLE) vasculitis, and autoantibody-mediated endothelial cell activation are also discussed.

Impact:

  • Provides a comprehensive overview of adhesion molecule function in collagen disease pathogenesis.
  • Identifies key molecular mechanisms underlying tissue damage and inflammation.
  • Suggests potential therapeutic targets for managing collagen-related autoimmune disorders.

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...
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...
Type IV Collagen of Basal Lamina01:05

Type IV Collagen of Basal Lamina

Type IV collagen is a 400 nm long, network-forming collagen that acts as a barrier between the epithelial and endothelial cells. Type IV collagen  forms the backbone of the basement membrane by scaffolding with laminin, entactin, proteoglycans, and fibronectin. Apart from rendering structural support to the basement membrane, it also helps entail signaling potentials necessary for both pathological and physiological functions.
A type IV collagen molecule has six alpha chains which can exist in...
Adherens Junctions01:24

Adherens Junctions

Strong contact points between adjacent cells anchor them to each other, forming tissues. Such anchoring junctions are of two types –  adherens junctions and desmosomes. Adherens junctions are abundant in tissues such as  epithelium and endothelium, forming a continuous zone of adhesion called the adhesion belt. In other tissues, such as  heart muscle, they appear as clusters, linking the cells to produce coordinated heart muscle contraction.
Adherens Junctions are Dynamic

Cell Adhesion Molecules - Types and Functions

Cell adhesion molecules (CAMs) are pivotal to multicellularity and the coordinated functioning of tissues and organ systems. They enable physical interactions between cells and provide mechanical strength to tissues. They also function as receptors for signal transmission across the plasma membrane. The CAMs are broadly classified into four families - integrins, cadherins, selectins, and immunoglobulin-like CAMs (IgCAMs).
