Summary
Cellular interactions drive disease, with selectins and their ligand P-selectin glycoprotein ligand 1 (PSGL-1) key players in inflammation and cancer. Inhibiting these interactions offers therapeutic potential.
Area of Science:
- Immunology
- Cell Biology
- Pathology
Background:
- Cellular interactions are fundamental to human disease pathogenesis.
- Heterotypic cellular aggregates, involving hematopoietic and nonhematopoietic cells, are implicated in inflammation and cancer progression.
- Selectins and their ligands are critical mediators of cell-cell adhesion.
Purpose of the Study:
- To review the role of selectins in inflammatory, thrombotic, and malignant disorders.
- To highlight P-selectin glycoprotein ligand 1 (PSGL-1) as a universal ligand for selectins.
- To discuss the pathological significance of PSGL-1/selectin interactions.
Main Methods:
- Literature review of selectin and PSGL-1 functions in disease.
- Analysis of selectin-ligand interactions in physiological and pathological contexts.
- Emphasis on mechanisms driving severe disease outcomes.
Main Results:
- Selectins are crucial modulators of inflammation, thrombosis, and cancer.
- P-selectin glycoprotein ligand 1 (PSGL-1) acts as a key ligand for all selectins.
- PSGL-1's promiscuous binding contributes to disease severity.
Conclusions:
- Selectin-mediated cellular interactions, particularly involving PSGL-1, are central to disease.
- Targeting selectin-PSGL-1 interactions presents a promising therapeutic strategy for inflammatory and malignant conditions.

4.6K
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,...

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.

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,...

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...

Metastasis is the spread of cancer cells from the original site to distant locations in the body. Cancer cells can spread via blood vessels (hematogenous) as well as lymph vessels in the body.

The epithelial-to-mesenchymal transition or EMT is a developmental process commonly observed in wound healing, embryogenesis, and cancer metastasis. EMT is induced by transforming growth factor-beta (TGF-β) or receptor tyrosine kinase (RTK) ligands, which further...

Invadosome is a broad category of cell surface structures with proteolytic activity that degrades the extracellular matrix (ECM). Invadosomes are present in normal cell types, including macrophages, endothelial cells, and neurons, as well as tumor cells. Although the macrophage podosomes and tumor cell invadopodia are classified as invadosomes, they have different structures, molecular pathways, and functions. Podosomes are short structures that last for a few minutes. However,...
