Insights

Pathogens exploit cell adhesion molecules to invade epithelial cells, highlighting their role in disease. Studying these interactions reveals crucial details about cell junction machinery. Keywords: cell adhesion, pathogens, epithelial cells, cell junctions.

Area of Science:

  • Cell Biology
  • Microbiology
  • Immunology

Background:

  • Cell-cell adhesion is vital for tissue structure, cell polarity, and organ development.
  • Epithelial barriers formed by cell adhesion prevent pathogen entry.
  • Pathogens have evolved mechanisms to target and disrupt cell adhesion for invasion.

Purpose of the Study:

  • To investigate how pathogens target cell adhesion molecules.
  • To understand the role of cell adhesion in epithelial barrier function and pathogen invasion.
  • To utilize pathogen interactions as a tool to study eukaryotic cell junction machinery.

Main Methods:

  • Analysis of pathogen adherence and invasion mechanisms.
  • Microscopic and molecular techniques to study cell junctions.
  • Comparative studies across different pathogen types (viruses, bacteria, parasites).

Main Results:

  • Pathogens specifically target diverse cell adhesion molecules.
  • Disruption of cell adhesion by pathogens compromises epithelial integrity.
  • Pathogen interactions provide insights into the dynamics of cell-cell junctions.

Conclusions:

  • Pathogen strategies for cell adhesion targeting are diverse and effective.
  • Understanding these interactions is key to developing new therapeutic strategies.
  • Pathogens serve as valuable probes for dissecting fundamental cell biology processes.

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.

Colonisation of Pathogens01:25

Colonisation of Pathogens

Pathogen colonization of host tissues is a critical step in the development of infectious diseases. Various pathogenic microorganisms, including bacteria, fungi, viruses, and protozoa, have evolved complex strategies to attach to, invade, and persist within host environments. These mechanisms enable pathogens to establish infections, evade immune responses, and resist antimicrobial treatments.Attachment to Host CellsIn bacteria, colonization typically begins with adherence to host epithelial...

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).

Immunoglobulin-like Cell Adhesion Molecules01:31

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...
What are Membranes?01:24

What are Membranes?

A cell's plasma membrane demarcates the cell's borders and determines the nature of its interaction with the environment. Cells exclude certain substances, take in others, and excrete some others in controlled quantities. The plasma membrane must be flexible to allow certain cells, such as red and white blood cells, to change their shape while passing through narrow capillaries. These are the more obvious plasma membrane functions. In addition, the plasma membrane's surface carries markers that...
