LSKL, Inhibitor of Thrombospondin (TSP-1) 是一种衍生自 LAP-TGFβ 的四肽，是一种竞争性的 TGF-β1 拮抗剂。LSKL, Inhibitor of Thrombospondin (TSP-1) 抑制 TSP-1 与 LAP 的结合并减轻肾间质纤维化和肝纤维化。LSKL, Inhibitor of Thrombospondin (TSP-1) 通过抑制 TSP-1 介导的 TGF-β1 活性来抑制蛛网膜下纤维化，防止慢性脑积水的发生并改善蛛网膜下腔出血后的长期神经认知缺陷。LSKL, Inhibitor of Thrombospondin (TSP-1) 可以轻松穿越血脑屏障。

LSKL, Inhibitor of Thrombospondin (TSP-1) is a latency-associated protein (LAP)-TGFβ derived tetrapeptide and a competitive TGF-β1 antagonist. LSKL, Inhibitor of Thrombospondin (TSP-1) inhibits the binding of TSP-1 to LAP and alleviates renal interstitial fibrosis and hepatic fibrosis. LSKL, Inhibitor of Thrombospondin (TSP-1) suppresses subarachnoid fibrosis via inhibition of TSP-1-mediated TGF-β1 activity, prevents the development of chronic hydrocephalus and improves long-term neurocognitive defects following subarachnoid hemorrhage (SAH). LSKL, Inhibitor of Thrombospondin (TSP-1) can readily crosse the blood-brain barrier.

TGF-β1

The KTFR sequence from ADAMTS1 is responsible for the interaction with the LSKL, Inhibitor of Thrombospondin (TSP-1) (LSKL peptide) from the latent form of TGF-β, leading to its activation. There is a stable binding mode between LSKL, Inhibitor of Thrombospondin (TSP-1) and ADAMTS1 KTFR sequence, characterized by 3 salt bridges and 2 hydrogen bonds. has not independently confirmed the accuracy of these methods. They are for reference only.

LSKL, Inhibitor of Thrombospondin (TSP-1) (1 mg/kg; intraperitoneal injection; male Sprague-Dawley rats) is protective against subarachnoid fibrosis, attenuates ventriculomegaly and effectively suppresses hydrocephalus. LSKL, Inhibitor of Thrombospondin (TSP-1) treatment inhibits TGF-β1 activity and subsequent Smad2/3 signaling.
LSKL, Inhibitor of Thrombospondin (TSP-1) (30 mg/kg, i.p.) successfully inhibits transforming growth factor (TGF) β-Smad signal activation induced by partial hepatectomy. LSKL, Inhibitor of Thrombospondin (TSP-1) successfully attenuates TGF-β-Smad signal activation by antagonizing TSP-1, but not by reducing TSP-1 protein expression. LSKL, Inhibitor of Thrombospondin (TSP-1) accelerates hepatocyte proliferation after hepatectomy. has not independently confirmed the accuracy of these methods.
