Summary
E-selectin ligand-1 (ESL-1) is a key molecule for hematopoietic progenitor cell trafficking. This study reveals ESL-1
Area of Science:
- Hematology
- Cell Biology
- Immunology
Background:
- E-selectin plays a crucial role in the trafficking of leukocytes and hematopoietic stem and progenitor cells (HSPCs).
- Understanding the specific ligands involved in HSPC trafficking is essential for regenerative medicine and stem cell transplantation.
Purpose of the Study:
- To investigate the role of E-selectin ligand-1 (ESL-1) as a specific ligand for E-selectin on hematopoietic progenitors.
- To determine the contribution of ESL-1 to the trafficking of these progenitor cells.
Main Methods:
- The study likely involved in vitro assays to assess ESL-1 binding to E-selectin.
- Analysis of hematopoietic progenitor cell behavior in response to E-selectin and ESL-1.
Main Results:
- E-selectin ligand-1 (ESL-1) was identified as a highly selective ligand for E-selectin on hematopoietic progenitors.
- ESL-1 demonstrated unexpected but significant contributions to the trafficking mechanisms of these progenitor cells.
Conclusions:
- ESL-1 is a critical mediator of E-selectin-dependent trafficking for hematopoietic progenitors.
- These findings have implications for understanding and potentially manipulating stem cell homing and engraftment.

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,...

3.3K
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...

2.8K
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.

Proteins are dynamic macromolecules that carry out a wide variety of essential processes; however, the activities of most proteins depend on their interactions with other molecules or ions, known as ligands.
Protein-ligand interactions are quite specific; even though numerous potential ligands surround a cellular protein at any given time, only a particular ligand can bind to that protein. Moreover, a ligand binds only to a dedicated area on the surface of the protein, known as the...

01:15Activation of Integrins
4.3K
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...
