This study shows the role of adrenergic mechanisms in the development of fluorescent glioma in rats and the impairment of the blood-brain barrier (BBB) permeability. The results demonstrate that the progression of glioma was accompanied by a gradual increase in the BBB permeability and an increased expression of vascular beta2-adrenoreceptors (B2-AR). The pharmacological blockade of B2-AR reduced the degree of BBB disruption, the migration of cancer cells and increased the survival of animals.
