The Structure of a CXCR4:Chemokine Complex
CXCR4 was the first chemokine receptor to be identified as an HIV coreceptor in 1996 (1). Along with the importance of CXCR4 in development, it was also discovered as a key chemokine receptor in the metastasis of breast (2) and numerous other cancers (3). These were the main reasons that motivated us to pursue structural studies of CXCR4 with synthetic inhibitors and chemokines. However, my lab...
متن کاملPreparation and preliminary biological evaluation of [153Sm] samarium AMD3100; towards a possible therapeutic chemokine receptor CXCR4 targeting complex
Introduction: In continuation of recent development of possible C-X-C chemokine receptor type 4 (CXCR4) imaging agents, we report the development of a possible CXCR4 targeted therapy agent. Methods: [153Sm]labeled 1,1′-[1,4-phenylenebis(methylene)] bis-1,4,8,11-tetraazacyclo -tetradecane ([153Sm]-AMD3100) was prepared using [153Sm]SmCl3 and AMD-3100 ...
متن کاملcxcr4: a potential chemokine receptor for future regenerative therapeutic target
understanding the molecular mechanisms in regeneration could help the stem cell therapists to improve the clinical practices and could be considered a major milestone in the translation of stem cell research to clinics. chemokines have been described as one of the most significant singling networks in stem cells homing and regeneration of damaged organs. cxcr4/cxcl12 has been known as a key pla...
متن کاملAgonists for the Chemokine Receptor CXCR4
The development of agonists for the chemokine receptor CXCR4 could provide promising therapeutic candidates. On the basis of previously forwarded two site model of chemokine-receptor interactions, we hypothesized that linking the agonistic N-terminus of SDF-1 to the T140 backbone would yield new high-affinity agonists of CXCR4. We developed chimeras with the agonistic SDF-1 N-terminus grafted t...
متن کاملMolecular Imaging of Chemokine Receptor CXCR4
CXCR4 was found to be expressed by many different types of human cancers and its expression has been correlated with tumor aggressiveness, poor prognosis and resistance to chemotherapy. CXCR4 was also shown to contribute to metastatic seeding of organs that express its ligand CXCL12 and support the survival of these cells. These findings suggest that CXCR4 is a potentially attractive therapeuti...
