Integrin heart
NettetIntegrins and their ligands play key roles in development, immune responses, leukocyte traffic, hemostasis, and cancer and are at the heart of many human diseases—genetic, autoimmune, and others. They are the target of effective therapeutic drugs against thrombosis and inflammation, and integrins are receptors for many viruses and bacteria.

NettetIntegrins are heterodimeric, transmembrane receptors that are expressed in all cells, including those in the heart. They participate in multiple critical cellular processes … Nettet20. aug. 2009 · The integrin family is composed of 24 αβ heterodimeric members that mediate the attachment of cells to the extracellular matrix (ECM) but that also take part in specialized cell-cell interactions. Only a subset of integrins (8 out of 24) recognizes the RGD sequence in the native ligands.

Each … Nettet15. feb. 2016 · Before the identification of the integrin family, cells were thought to be anchored to collagens indirectly through tissue-specific nectins [from nectere (lat.): to bind, join together]. One such nectin is osteonectin, now known as secreted protein acidic and rich in cysteine (SPARC), which is present in bone and binds Ca 2+ and collagen I …

NettetCells respond to extracellular mechanical forces through the assembly of integrin adhesion complexes (IACs) that provide a scaffold through which cells sense and transduce responses to those forces. IACs are composed of transmembrane integrin receptors that bind to extracellular matrix (ECM) proteins externally and connect with … chasm summitNettetIn cardiac fibroblasts, integrins mediate cell growth and adhesion.
