Insights

Cell adhesion molecules (CAMs) regulate cell processes and tissue organization. EpCAM immunohistochemistry shows promise as a diagnostic tool for disturbed epithelial tissues, aiding in disease diagnosis.

Area of Science:

  • Molecular Biology
  • Cell Biology
  • Oncology

Background:

  • Cell adhesion receptors (CAMs) are crucial for cell growth, differentiation, and death, mediating cell-cell and cell-environment interactions.
  • CAMs play a role in tissue organization and influence disease development and characteristics in pathological conditions.
  • Altered expression patterns of adhesion molecules, such as cadherins, integrins, and CD44, are observed in neoplastic epithelium.

Purpose of the Study:

  • To review studies investigating the cell adhesion molecule EpCAM (Epithelial Cell Adhesion Molecule).
  • To evaluate the utility of EpCAM as a diagnostic marker in epithelial tissues.
  • To assess the role of EpCAM in understanding epithelial lineage and neoplastic changes.

Main Methods:

  • Review of existing studies utilizing antibodies against EpCAM.
  • Analysis of EpCAM expression patterns in various epithelial tissues and neoplastic conditions.
  • Immunohistochemical assessment of EpCAM in disturbed epithelial tissues.

Main Results:

  • EpCAM, initially considered a pan-carcinoma antigen, is identified as a marker of epithelial lineage.
  • Numerous studies have explored EpCAM expression using generated antibodies across diverse epithelial tissues.
  • Observed shifts in EpCAM expression patterns are linked to neoplastic changes in epithelial tissues.

Conclusions:

  • EpCAM immunohistochemistry is a valuable tool for diagnosing epithelial tissue abnormalities.
  • EpCAM expression analysis aids in distinguishing normal from disturbed epithelial tissues.
  • The findings support the diagnostic potential of EpCAM in pathology.

Immunoglobulin-like Cell Adhesion Molecules

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

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).

Cadherins in Tissue Organization01:19

Cadherins in Tissue Organization

The cadherins are a superfamily of cell adhesion molecules comprising over 180 variants, with specific tissues expressing a particular combination of cadherin types. Cadherins generally exhibit homophilic binding; i.e., cadherins on one cell bind to cadherins of the same or closely related type on another cell. Thus, cells of the same type have a specific affinity to bind to each other and sort themselves into clusters to form tissues.

Role of Ephrin-Eph Signalling in Intestinal Stem Cell Renewal

Erythropoietin-producing hepatocellular carcinoma receptor (Eph) and its ligand, Eph receptor-interacting protein (Ephrin) were first discovered in the human carcinoma cell line, hence the name. Ephrin-Eph interaction guides cells to reach their appropriate location in adult tissues. They also play an essential role in the immune system by helping in immune cell migration, adhesion, and activation. Based on their structure and function, Eph is divided into two classes — EphA and EphB.
Selectins01:25

Selectins

Cell adhesion is  an essential aspect of multicellularity. While stable cell interactions usually occur between cells of the same type, transient cell interactions occur between cells of different tissue types, such as between neutrophils and endothelial cells. Selectins are one class of cell adhesion molecules (CAMs) that bind carbohydrate ligands to form transient cell adhesion. They are rod-like proteins with a long extracellular part of variable length ending with the lectin domain, which...
