Receptores ativados por protease (PARs) pertencem à família de GPCRs. Desses, PAR-1, PAR-3 e PAR-4 são ativados por trombina, e PAR-2 por tripsina. Como as proteases, peptídeos sintéticos (PARs-AP) também ativam esses receptores. Estudamos o papel dos PARs na reatividade vascular de Wistar e SHR. In vitro, PAR-1 AP, promoveu maior vasoconstrição em aorta com endotélio (E+) de SHR vs Wistar. PAR-2 AP promoveu vasodilatação similar em aorta E+ de SHR e Wistar, enquanto PAR-4 AP e peptídeos reversos não causaram efeito. In vivo/in situ PAR-1 e PAR-2 AP mostraram intensa vasomotilidade em arteríolas mesentéricas. A expressão gênica de PAR-1 está aumentada em aorta e arteríolas de SHR, mas a expressão protéica está aumentada apenas em arteríolas...
