Human Integrin beta-7(ITGB7) ELISA kit

Integrin alpha-4/beta-7 (Peyer patches-specific homing receptor LPAM-1) is an adhesion molecule that mediates lymphocyte migration and homing to gut-associated lymphoid tissue (GALT). Integrin alpha-4/beta-7 interacts with the cell surface adhesion molecules MADCAM1 which is normally expressed by the vascular endothelium of the gastrointestinal tract. Interacts also with VCAM1 and fibronectin, an extracellular matrix component. It recognizes one or more domains within the alternatively spliced CS-1 region of fibronectin. Interactions involves the tripeptide L-D-T in MADCAM1, and L-D-V in fibronectin. Binds to HIV-1 gp120, thereby allowing the virus to enter GALT, which is thought to be the major trigger of AIDS disease. Interaction would involve a tripeptide L-D-I in HIV-1 gp120. Integrin alpha-E/beta-7 (HML-1) is a receptor for E-cadherin.

1. CCR9 and Integrin-beta7 expression has a differential effect on graft fate during acute graft-versus-host disease (GVHD) of the liver depending on the GVHD target tissue. PMID: 26348893
2. Integrin alpha4beta7 binds gp120 but does not mediate HIV envelope-induced death signaling. PMID: 22822002
3. Consistent with structural predictions, strain increases beta-integrin binding to FLNA, whereas it causes FilGAP to dissociate from FLNA, providing a direct and specific molecular basis for cellular mechanotransduction PMID: 21926999
4. a role for integrin-beta7 in MM-cell adhesion, migration, and BM homing, and pave the way for a novel therapeutic approach targeting this molecule. PMID: 21474670
5. Data show that integrin beta7 and CCR6 identify four distinct stages of memory CD4+ T cell differentiation. PMID: 21398606
6. T cell stimulation leads to incresed phosphorylation of integrin beta 7 and reveals threonine phosphorylation of beta 7. PMID: 12682249
7. bipolar metal ion cluster sites stabilize two alternative phases of adhesion PMID: 14608374
8. In a chronic ileitis model, pathogenic CD4+ T cells use the integrin beta 7/MAdCAM-1 pathway in order to recirculate to the chronically inflamed small intestine. PMID: 15699171
9. Integrin activation marker CD103 (alphaEbeta7) is expressed on Epstein-Barr virus-specific tonsil-resident (but not peripheral blood mononuclear leukocyte-derived) cytotoxic T lymphocytes. PMID: 16177076
10. Beta7 integrin is a major galectin-1-glycosylated counterreceptor involved in immune developmental synapse formation. PMID: 16818733

12. Cadherin-E interaction with integrin alphaEbeta7 causes antitumor cytotoxic response by CD8+/CD103+ tumor-reactive T lymphocytes. PMID: 17325197
13. Taken together, these data establish beta7 ITG as a new molecular target of PAHs, whose up-regulation by these environmental contaminants most likely requires activation of co-operative pathways involving both AhR and c-maf. PMID: 17490615
14. analysis of the migfilin-filamin interaction and competition with integrin beta 7 tails PMID: 18829455
15. Mechanical force applied to filamin can expose cryptic integrin binding sites. PMID: 19699211
