Summary
Junctional adhesion molecules (JAMs) are key proteins involved in cell connections and inflammatory responses. This review explores their diverse roles in health and disease, particularly in inflammation and vascular injury.
Area of Science:
- Immunology
- Cell Biology
- Molecular Biology
Background:
- Junctional adhesion molecules (JAMs) are immunoglobulin superfamily transmembrane proteins.
- JAMs are found in endothelial and epithelial cells near tight junctions, and also in circulating cells like leukocytes and platelets.
- JAMs influence barrier function, inflammatory reactions, vascular injury responses, and tumor angiogenesis.
Purpose of the Study:
- To review the diverse roles of junctional adhesion molecules.
- To emphasize the involvement of JAMs in inflammatory reactions and vascular responses to injury.
Main Methods:
- Literature review of junctional adhesion molecule functions.
- Analysis of JAMs' roles in normal and pathological conditions.
Main Results:
- JAMs regulate permeability and are involved in cell-cell adhesion.
- JAMs are crucial mediators of inflammatory and immune responses.
- JAMs play significant roles in vascular repair and disease.
Conclusions:
- Junctional adhesion molecules are multifunctional proteins with critical roles in maintaining tissue integrity and mediating cellular responses.
- Understanding JAMs' functions is vital for developing therapeutic strategies for inflammatory diseases and vascular disorders.

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.

01:03Anchoring Junctions
Anchoring junctions are multiprotein complexes that help cells connect to other cells and the extracellular matrix. Anchoring junctions are present on the lateral and basal surfaces of cells, providing strong and flexible connections. Focal adhesions are often formed due to cell interactions with the ECM substrata, which initiate signal transduction via kinase cascades and other mechanisms. Together, they provide stability and tissue integrity. There are three types of anchoring junctions:...
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...

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.

01:29Tight Junctions
Tight junctions are molecular seals between cells that prevent the leaking of fluids, ions, and other small solutes across cavities and compartments in multicellular organisms. They are mainly composed of claudin and occludin transmembrane proteins, and other proteins such as tricellulin and JAM (junctional adhesion molecule). All these proteins are 4-pass transmembrane proteins, except JAM, which is a single-pass transmembrane protein belonging to the immunoglobulin superfamily. The...
01:26Tension Response at Adherens Junctions
The adherens junctions that anchor cells together are multi-protein complexes that dynamically adapt to mechanical stimuli such as tensile forces and shear stress. Mechanosensory proteins in these junctions can sense such mechanical stimuli and undergo a shift in their conformation, resulting in an altered function — a process called mechanotransduction.
