Neuromediators in the cerebellar blood-brain barrier and its microenvironment. Immunocytochemical demonstration of taurine, glycine, serotonin, thiamin and AATase.

Cerebral capillaries represent the responsible structure for the establishment of the Blood-Brain Barrier (BBB). It is known that in the Central Nervous System a relationship exists between neuronal activity and microvascular blood flow and permeability. Our analysis demonstrates the presence of several putative neuromediators-taurine.
