| Summary: | Angiogenesis is essential during development or when tissue restoration and oxygenation is required. Limited or excessive formation of blood vessels is a hallmark of several pathologies, and many angiogenesis-related pathways are being studied to highlight potential targets for effective angiogenesis-stimulating or inhibiting therapeutic approaches. A few studies point to the adrenergic system as a significant regulator of angiogenesis, directly or indirectly. Functional adrenergic receptors are expressed on endothelial cells and affect their response to the adrenergic system. The latter can also upregulate the release of growth factors by mural cells of the vessel wall, blood cells or cancer cells, thus subsequently affecting endothelial cell functions and angiogenesis. In the present study we summarize up-to-date literature on the known effects of the adrenergic receptors on physiological and pathological angiogenesis.
