1 Yohimbine promotes cardiac NE release and prevents LPS-induced cardiac dysfunction via blockade of presynaptic alpha2A-adrenergic receptor. Yohimbine adrenergic receptor, alpha 2a Mus musculus
2 Immunohistochemical analysis revealed that cardiac alpha2A-AR was mostly located in sympathetic nerve presynaptic membrane; YHB decreased cardiac alpha2A-AR level and promoted cardiac norepinephrine (NE) release in endotoxemic mice. Yohimbine adrenergic receptor, alpha 2a Mus musculus
3 Immunohistochemical analysis revealed that cardiac alpha2A-AR was mostly located in sympathetic nerve presynaptic membrane; YHB decreased cardiac alpha2A-AR level and promoted cardiac norepinephrine (NE) release in endotoxemic mice. Yohimbine adrenergic receptor, alpha 2a Mus musculus
4 Altogether, these findings indicate that YHB attenuates LPS-induced cardiac dysfunction, at least in part, through blocking presynaptic alpha2A-AR and thus increasing cardiac NE release. Yohimbine adrenergic receptor, alpha 2a Mus musculus
