Summary
Cell adhesion involves over 50 molecules, often grouped into superfamilies like immunoglobulin. Key principles such as kinetics, affinities, and binding sites are crucial for understanding cell-cell interactions.
Area of Science:
- Immunology
- Cell Biology
- Biochemistry
Background:
- Cell adhesion is mediated by over 50 molecules, many belonging to superfamilies.
- The immunoglobulin superfamily includes over half of all leukocyte adhesion molecules.
- Understanding cell adhesion principles is vital in immunology and cell biology.
Purpose of the Study:
- To review the fundamental principles governing cell-cell adhesion.
- To illustrate these principles using specific cell adhesion molecules (CAMs).
- To provide a framework for understanding molecular interactions in cell adhesion.
Main Methods:
- Review of established principles of cell adhesion kinetics, equilibria, and binding site analysis.
- Examination of homotypic interactions involving CD66 and CD31.
- Analysis of heterotypic interactions between ICAM-1, 2, 3 and LFA-1.
Main Results:
- Cell adhesion principles encompass kinetics, affinities, homotypic/heterotypic interactions, and binding site mapping.
- CD66 and CD31 exemplify homotypic cell-cell adhesion.
- ICAM-1, 2, and 3 interacting with LFA-1 demonstrate heterotypic adhesion.
Conclusions:
- Cell adhesion is a complex process governed by well-defined molecular principles.
- Specific CAMs like CD66, CD31, ICAMs, and LFA-1 serve as models for understanding adhesion mechanisms.
- This review consolidates key concepts for researchers in cell adhesion and immunology.

01:24Overview of Cell-Matrix Interactions
The extracellular matrix or ECM holds cells together to form a tissue and allows the cells within the tissue to communicate. ECM comprises proteins such as fibronectin, collagen, laminin, etc. The most abundant protein in this space is collagen. Collagen fibers are interwoven with carbohydrate-containing protein molecules called proteoglycans. ECM allows cell migration and provides a structural scaffold at cell adhesion that anchors the cell when the extracellular matrix proteins interact with...
01:17Intracellular Signaling Affects Focal Adhesions
Integrins act both as extracellular input receivers and as intracellular processing activators. As their name suggests, integrins are entirely integrated into the membrane structure. Their hydrophobic membrane-spanning regions interact with the phospholipid bilayer's hydrophobic region. These membrane receptors provide extracellular attachment sites for effectors like hormones and growth factors. They activate intracellular response cascades when their effectors are bound and active.

01:24Adherens 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.

01:20Cell 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).

01:31Immunoglobulin-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...
