Biochem/physiol Actions

Iloprost is a potent prostacyclin PGI2 analog that binds with equal affinity to human prostacyclin (Prostanoid IP) and prostaglandin EP1 receptors. Iloprost acts as a vasodilator and antihypertensive, and inhibits the ADP, thrombin, and collagen-induced aggregation of human platelets. Iloprost dilates systemic and pulmonary arterial vascular beds and has been used clinically for pulmonary arterial hypertension (PAH), scleroderma, and Raynaud′s syndrome.
Iloprost is used to treat children with PH (pulmonary hypertension) after the surgery to clear CHD (congenital heart disease). In transplant patients, this prostacyclin analogue is used to inhibit renal dysfunction. Iloprost performs various functions like vasodilatation and cytoprotection. It has higher stability than prostacyclin.

Regulatory T cells (Treg) are immunosuppressive and negatively impact response to cancer immunotherapies. CREB-binding protein (CBP) and p300 are closely related acetyltransferases and transcriptional coactivators. Here, we evaluate the mechanisms by which CBP/p300 regulate Treg differentiation and the consequences of
