Summary
Inflammation, while protective, can cause chronic disease. Selectins mediate leukocyte adhesion during injury, and targeting these interactions with carbohydrate mimetics may offer therapeutic benefits for inflammatory conditions.
Area of Science:
- Immunology
- Cell Biology
- Biochemistry
Background:
- Inflammation is a critical host defense mechanism against infection and injury.
- Dysregulated inflammation contributes to chronic conditions like autoimmune diseases, Crohn's disease, and asthma.
- Leukocyte adhesion to endothelial cells, followed by diapedesis, is a key event in tissue injury responses.
Purpose of the Study:
- To investigate the molecular mechanisms underlying initial leukocyte-endothelium adhesion during inflammation.
- To explore the role of selectins and their carbohydrate ligands in inflammatory processes.
- To assess the potential of carbohydrate small-molecule mimetics as a therapeutic strategy for modulating inflammation.
Main Methods:
- Analysis of leukocyte-endothelium interactions at the cellular level.
- Identification and characterization of inducible adhesion molecules, specifically selectins.
- Investigation of carbohydrate-mediated molecular recognition in cell adhesion.
Main Results:
- Selectins on endothelial and leukocyte surfaces are crucial for initial cell adhesion.
- These selectin-ligand interactions appear to involve specific carbohydrate structures.
- The precise nature of these carbohydrate-mediated interactions is an active area of research.
Conclusions:
- Selectins play a pivotal role in the inflammatory response by mediating leukocyte adhesion.
- Understanding the carbohydrate-based interactions of selectins is essential for developing targeted therapies.
- Carbohydrate small-molecule mimetics show promise for therapeutic intervention in inflammatory diseases.

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,...

3.7K
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.

01:15Activation of Integrins
5.3K
Integrins bind ligands and transmit information from outside the cell to inside or vice-versa through an "outside-in signaling" or "inside-out signaling."
In "outside-in signaling," external factors in the extracellular space bind to exposed ligand binding sites on integrins. This causes the inactive protein to undergo a conformational change to become active. Integrins are often clustered on the cell membrane. Repetitive and regularly spaced ligand binding...

Animal and protozoan cells do not have cell walls to help maintain shape and provide structural stability. Instead, these eukaryotic cells secrete a sticky mass of carbohydrates and proteins into the spaces between adjacent cells. This network of proteins and molecules is called an extracellular matrix or ECM.
Some ECM proteins assemble into a basement membrane to which the remaining components adhere. Proteoglycans typically form the bulk of the ECM while fibrous proteins, like collagen,...

Tumor Necrosis Factor (TNF), a proinflammatory cytokine, contributes significantly to the inflammation seen in Crohn's disease. It exists as soluble TNF and membrane-bound TNF, with actions mediated through TNF receptors (TNFR). TNFR activation leads to the release of proinflammatory cytokines, T-cell activation, collagen production, and leukocyte migration, all contributing to inflammation in Crohn's disease. Anti-TNF monoclonal antibodies, namely infliximab (Remicade), adalimumab...

Enzyme-linked receptors are cell-surface receptors acting as an enzyme or associating with an enzyme intracellularly. They make excellent drug targets. Drugs can bind to the extracellular ligand-binding domain or directly affect their enzymatic domain and alter their activity.
