Loss of barrier function in the vasculature promotes inflammatory signalling which in turn contributes to the progression of cardiovascular disease. cAMP can protect against endothelial dysfunction through the effectors PKA (protein kinase A) and Epac (exchange protein directly activated by cAMP). The present review outlines the role of Epac1 signalling within the endothelium and, in particular, the role of Epac1 in cytoskeletal dynamics and the control of cell morphology. The actin/cytoskeleton linker ezrin will be described in terms of the growing body of evidence placing it downstream of cAMP signalling as a mediator of altered cellular morphology.
