  • Canonical chemokine receptors as scavenging “decoys”

    The immune system depends on chemokines to direct cell migration during immune surveillance and inflammation CCR2 is an example of a dual-function receptor that directly regulates both cell migration and scavenging Scavenging allows cells to continuously migrate by remaining responsive to chemokines, it dampens the , and CCR5 switch purely to scavenging (D'Amico G. et al. 2000), becoming incapable of promoting cell migration, a phenomenon which is likely to be mediated by changes in the cell motility machinery with

  • Exploiting Dependence of Castration-Resistant Prostate Cancer on the Arginine Vasopressin ...

    Stimulation of AVPR2 with a selective agonist desmopressin promoted CRPC cell proliferation through cAMP In contrast, blocking AVPR2 with a selective FDA-approved antagonist, tolvaptan, reduced cell growth. Combinatorial use of AVPR1A and AVPR2 antagonists promoted apoptosis synergistically in CRPC cells. Furthermore, we found that castration-resistant cells produced AVP, the endogenous ligand for arginine vasopressin receptors, and knockout of AVP in CRPC cells significantly reduced proliferation suggesting
