Involvement of bradykinin in brain edema development after ischemic stroke

Stroke is the third leading cause of death in the Western world. Ischemic stroke is characterized by a rapid loss of brain function due to disturbance in the blood supply to a part of the brain. Due to fixed intracranial space, any increase in intracranial fluid volume, or progressive brain edema formation, contributes to further deterioration of the already impaired brain function. Bradykinin increases blood–brain barrier permeability and raises intracranial capillary blood pressure by arterial dilatation and venous constriction leading to brain edema formation. The aim of this paper is to summarize the recent research in the field of bradykinin function (structure, synthesis, signaling pathways, mechanism of action) followed by characterization of different types of brain edema development related to ischemic brain injury, together with the involvement of bradykinin in edema formation. Since there is currently no causal treatment addressing brain edema after ischemic stroke, specific bradykinin receptor antagonists are proposed as a possible new therapeutic approach.
