Haploinsufficient Rock1+/- and Rock2+/- Mice Are Not Protected from Cardiac Inflammation and Postinflammatory Fibrosis in Experimental Autoimmune Myocarditis.

ABSTRACT: Progressive cardiac fibrosis is a common cause of heart failure. Rho-associated, coiled-coil-containing protein kinases (ROCKs) have been shown to enhance fibrotic processes in the heart and in other organs. In this study, using wild-type, Rock1+/- and Rock2+/- haploinsufficient mice and mouse model of experimental autoimmune myocarditis (EAM) we addressed the role of ROCK1 and ROCK2 in development of myocarditis and postinflammatory fibrosis. We found that myocarditis severity was comparable in wild-type, Rock1+/- and Rock2+/- mice at day 21 of EAM. During the acute stage of the disease, hearts of Rock1+/- mice showed unaffected numbers of CD11b+CD36+ macrophages, CD11b+CD36-Ly6GhiLy6chi neutrophils, CD11b+CD36-Ly6G-Ly6chi inflammatory monocytes, CD11b+CD36-Ly6G-Ly6c- monocytes, CD11b+Sig
