The aim of this study was to investigate the effects of TSPO modulation by PK11195, alone or in combination with nitric oxide synthase (NOS) inhibition by Nω-Nitro-L-arginine methyl ester hydrochloride (L-NAME), on cardiometabolic, inflammatory, oxidative stress, and histopathological parameters in an experimental model of isoprenaline-induced MI in rats. Here, TSPO is linked to myocardial infarction.
