ADORA2B and myocardial ischemia: A2BAR mediates adenosine-induced vasoconstrictor vasomotor effects in human chorioallantoic membrane vasoconstriction by synthesizing thromboxane receptor activators or related prostaglandin-like agentsBlockage of the adenosine A2B receptor prevents cardiac fibroblasts overgrowth in rats with pulmonary arterial hypertensionActivation of adenosine A2B receptor alleviates myocardial ischemia-reperfusion injury by inhibiting endoplasmic reticulum stress and restoring autophagy fluxA2BAR is involved in altered ventricular function in mice
