Integrin trafficking in cells and tissues
Nettet27. jul. 2011 · Integrin Trafficking and Tumor Progression Integrins are major mediators of cancer cell adhesion to extracellular matrix. Through this interaction, integrins play critical roles in cell migration, invasion, metastasis, and resistance to apoptosis during tumor progression. NettetIntegrins are a family of transmembrane cell surface molecules that constitute the principal adhesion receptors for the extracellular matrix (ECM) and are indispensable …

Nettet7. mar. 2024 · Integrin LFA-1 plays a critical role in T-cell migration and in the formation of immunological synapses. LFA-1 functions through interacting with its ligands with differing affinities: low, intermediate, and high. Most prior research has studied how LFA-1 in the high-affinity state regulates the trafficking and functions of T cells. LFA-1 is also … Nettet1. jan. 2015 · Integrin and Cell Adhesion Molecules. Integrins are transmembrane αβ-heterodimers involved in cell adhesion to extracellular matrix. They can also be involved in cell-cell interactions, including immune cells (Hynes 2002). There are 18 α-subunits that can associate with 8 β-subunits, but only 24 couples have been described.
