Therefore, we conclude that the ISO/PE-induced mouse heart failure model can activate both the SNS and RAAS, through the activation of both α-adrenergic receptor (α-AR) and β-adrenergic receptor (β-AR), which is more consistent with the development of human heart failure than the ISO-induced model and is expected to be a unique and representative heart failure modeling method. Here, ADRB2 is linked to heart failure.
