Honokiol Protects against Anti-β1-Adrenergic Receptor Autoantibody-Induced Myocardial Dysfunction via Activation of Autophagy

Figure 2

Honokiol ameliorated cardiac contractility suppressed by β1-AAB. Representative M-mode echocardiograms were obtained from the rats at 12 h after each treatment. (a) Saline treatment (control group); (b) β1-AR-ECII administration (β1-AAB group); (c) β1-AR-ECII plus HNK administration (β1-AAB + HNK group); and (d) β1-AR-ECII plus saline administration (β1-AAB + vehicle group). HNK: honokiol.
