Sterile inflammation after permanent distal MCA occlusion in hypertensive rats.

ABSTRACT: The pathophysiology of stroke is governed by immune reactions within and remote from the injured brain. Hypertension, a major cause and comorbidity of stroke, entails systemic vascular inflammation and may influence poststroke immune responses. This aspect is, however, underestimated in previous studies. Here we aimed to delineate the sequence of cellular inflammation after stroke in spontaneously hypertensive (SH) rats. Spontaneously hypertensive rats were subjected to permanent middle cerebral artery occlusion and killed after 1 or 4 days. Immune cells of the peripheral blood and those which have infiltrated the injured brain were identified and quantified by flow cytometry. The spatial distribution of myeloid cells and T lymphocytes, and the infarct volume were assessed by histology. We
