Coupling factor 6 enhances the spontaneous microaggregation of platelets by decreasing cytosolic cAMP irrespective of antiplatelet therapy

The spontaneous microaggregation of platelets (SMAPs) is a marker for the prognosis of patients with cardiovascular diseases. Coupling factor 6 (CF6) binds to the plasma membrane ATP synthase and ...

Coupling factor 6 attenuates CXCR4 expression through the HIF-1α and c-Src pathways and promotes endothelial apoptosis and inflammation

Vascular endothelial cells are exposed to an acidic pH, and CXC chemokine receptor type 4 (CXCR4) is a key protective molecule against acidosis. We investigated the effect of coupling factor 6 (CF6), ...

RF Fundamentals: What actually creates the 90 degree coupler phase shift? Part 2

The term ζ is the coupling factor and is equal to the magnitude of the maximum coupling between the lines. The maximum coupling is written as maximum coupling = ζdB = 20Log(ζ) for BL = π/2. With ...
