Abstract
Blood–brain barrier (BBB) is a brain protective structure composed by endothelial cells, astrocytes and pericytes characterized by specific transport systems expressed on their surface. Moreover, the tight junctions, in the paracellular space, and the adherens junctions, in the basolateral space of the endothelial cells create a physical barrier hardly crossable from the most part of common drugs. Despite the BBB is vital for the central nervous system (CNS), it restricts drug delivery to this tissue. To overcome this obstacle many drug delivery systems (DDS) have been developed. Polymeric nanocarriers, solid lipid nanocarriers (SLN) and liposomes are developed to deliver drugs otherwise not able to pass the BBB, due to their physico-chemical characteristics. Besides their capacity to pass biological barriers, the potential advantages of nanocarriers are their capability to load a high quantity of drug with low cytotoxicity.
