Schematic of the main roles of bradykinin in the Neurovascular Unit via B1- and B2- Receptors. Endothelium (with tight junctions), astrocytes, neurons, oligodendrocytes, microglia, and pericytes compose the neurovascular unit. BBB, blood-brain barrier; BK, bradykinin; HMWK, High molecular Weight Kininogen; Plg, plasminogen; tPA, tissue-type plasminogen activator.
