Structure of Cadherins01:25

Structure of Cadherins

3.3K
The cadherins were one of the first cell adhesion molecules discovered; the term “cadherins”   is based on their calcium-dependent adhering properties. The first cadherins discovered on the epithelial, neuronal, and placental cells were named E-cadherin, P-cadherin, and N-cadherin, respectively. These classical cadherins share sequence and structural similarities. Other cadherins, including those involved in cell signaling, are grouped into non-classical cadherins. This...

Mechanism of Lamellipodia Formation

2.5K
Cells migrating in response to external stimuli form lamellipodia, which are thin membrane protrusions supported by a mesh of linked, branched, or unbranched actin filaments. These actin filaments interact with myosin motor proteins, creating the dynamic actomyosin complex within the cytoskeleton. Contractility, or the ability to generate contractile stress, is inherent to the actomyosin complex. It helps cells detect the stiffness of the surrounding ECM and exert contractile force for...

Desmosomes01:05

Desmosomes

5.3K
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...

Catenins01:23

Catenins

2.3K
Catenins are characterized by multiple binding domains and dynamic structures that allow them to function as linker proteins in cell junction complexes. All catenins, except α-catenin, contain a characteristic protein sequence called the armadillo repeat and are therefore also called armadillo proteins.
Catenins in Cell Junctions
Catenins bind to cell adhesion molecules such as cadherins and link them to different cytoskeletal proteins depending on the type of cell junction. At the...

Immunoglobulin-like Cell Adhesion Molecules01:31

Immunoglobulin-like Cell Adhesion Molecules

3.2K
Immunoglobulin-like cell adhesion molecules or Ig-CAMs are a versatile group of cell surface glycoproteins belonging to the immunoglobulin protein superfamily. Ig-CAMs possess the characteristic immunoglobulin protein domains and other domains such as the fibronectin type III domain. The Ig domains are glycosylated to varying degrees in different Ig-CAMs.
Ig-CAMs exhibit either homophilic binding (to other Ig-CAMs) or heterophilic binding (to other ligands such as integrins). While most Ig-CAMs...

Cell Adhesion Molecules - Types and Functions

6.6K
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).
CAM Families
The Integrin family of proteins is primarily  involved...

Area of Science:

  • Orthopedics
  • Pediatric Hand Surgery
  • Congenital Hand Differences

Background:

  • Camptodactyly presents as a congenital flexion contracture of the proximal interphalangeal (PIP) joint.
  • Etiology varies: single-finger cases may involve lumbrical muscle anomalies, while multiple-finger cases suggest flexor soft tissue deficiency.
  • Differentiating camptodactyly from other PIP extension deficits is crucial for appropriate management.

Purpose of the Study:

  • To elucidate the pathophysiology of camptodactyly.
  • To emphasize the importance of distinguishing camptodactyly from other conditions causing PIP joint extension lag.
  • To outline a strategic approach to managing camptodactyly, focusing on preventing contracture progression.

Main Methods:

  • Review of existing literature and clinical understanding of camptodactyly.
  • Analysis of the proposed etiologies for single versus multiple digit involvement.
  • Discussion of surgical considerations and the role of conservative management.

Main Results:

  • Single-finger camptodactyly linked to lumbrical muscle insertion anomalies.
  • Multiple-finger camptodactyly associated with flexor soft tissue shortage.
  • Surgical release of established contractures yields suboptimal results, highlighting the need for preventative strategies.

Conclusions:

  • A comprehensive understanding of camptodactyly's pathophysiology is essential for effective treatment.
  • Postoperative therapy, including night splinting and stretching, is critical for preventing contracture recurrence after surgical intervention.
  • A judicious approach prioritizing contracture prevention is recommended for managing camptodactyly.
