Summary
Nasal polyp recurrence may be linked to specific adhesion molecules like epithelial membrane antigen (EMA/mucin 1) and CD86. These molecules, particularly EMA, show higher expression in patients with recurrent nasal polyposis after surgery.
Area of Science:
- Immunology
- Oncology
- Rhinology
Background:
- Nasal polyposis is a chronic inflammatory condition of the nasal and paranasal sinuses.
- Adhesion molecules are implicated in the pathogenesis of nasal polyposis.
Purpose of the Study:
- To investigate the role of adhesion molecules, mucins, and oncogenes in the recurrence of nasal polyposis.
- To identify potential biomarkers for predicting nasal polyp recurrence.
Main Methods:
- A comparative study involving 21 patients with recurrent nasal polyposis (post-two surgeries) and 21 control patients (post-one surgery).
- Analysis of epithelial membrane antigen (EMA/mucin 1) and CD86 expression in stromal cells.
Main Results:
- Significant differences in stromal epithelial membrane antigen (EMA/mucin 1) (p < 0.001) and CD86 expression (p = 0.009) were found between the groups.
- High CD86 stromal expression was observed in 6 patients with recurrent polyps, but none in the control group.
- Stromal EMA was positively correlated with polyp recurrence in a logistic regression model.
Conclusions:
- Adhesion molecules, specifically EMA and CD86, may play a role in the prognosis and recurrence of nasal polyposis.
- These findings suggest potential therapeutic targets for managing recurrent nasal polyposis.

01:20Cell Adhesion Molecules - Types and Functions
8.1K
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
3.3K
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...

01:24Adherens Junctions
5.8K
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.

01:28Types of Membrane Protrusions
3.0K
The protrusion of the cell surface is an initial step for several cellular processes, including cell migration, phagocytosis, and neurite outgrowth. These membrane protrusions are a result of cytoskeletal rearrangement. The most widely observed cell protrusions include lamellipodia, pseudopodia, filopodia, microvilli, invadopodia, and podosomes. These protrusions can be of two types — static or dynamic.

01:25Structure of Cadherins
4.0K
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...

01:25Selectins
3.6K
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,...
