Thromboxane A2

Thromboxane A2 (TXA2) is a prostanoid mediator produced by the metabolism of Arachidonic acid (HY-109590) through the cyclooxygenase pathway. Thromboxane A2 activates the thromboxane-prostanoid (TP) receptors. Thromboxane A2 is a potent vasoconstrictor eicosanoid. Thromboxane A2 (TXA2) leads to potent vasoconstriction by stimulation of smooth muscle cells. Thromboxane A2 acts as s tonic immunoregulator to regulate adaptive immune responses[1][2].
