Core Tip

Core Tip: An effective and safe drug for treating liver fibrosis is urgently needed in current clinical practice. Here, we investigated and discovered that dihydroergotamine (DHE) could alleviate liver fibrosis by specific binding of transforming growth factor β type II receptor (TGFβR2) to disrupt the binding of TGFβR2 with TGFβ1, and ultimately suppressing its downstream TGFβ signaling pathway. DHE may be an effective anti-liver fibrosis drug, which could be employed in liver cirrhotic patients.
