From: Nano to micro delivery systems: targeting angiogenesis in brain tumors

Comparison between cerebral and noncerebral blood vessels. Cerebral blood vessel has tight junctions, which do not allow the passage of un-desirable and pathological substances to the brain parenchyma while non cerebral blood vessel allows better diffusion of drugs. Targeting the brain can be achieved using the drug itself or by using drug delivery platforms that release the drug at a specified location.
