    • The present invention provides an anti-atherosclerotic peptide, said peptide being an amphipathic helical peptide compared with human apoA-I, characterized by having at least 4 of the following 8 properties: a tandem repeating class A amphipathic helix linked by a proline which forms an optimal arrangement for lipid association, has bilayer membrane stabilizing properties, stimulates HIV-I Gp41-induced cell fusion, stimulates neutrophil activation, stimulates BSA-induced lysis of fatty acid-containing vesicles, stimulates human placental lactogen synthesis, effluxes phospholipid and cellular cholesterol from cholesterol-loaded cells, and competes with HDL for binding to cells. The present invention is also directed to pharmaceutical compositions, transgenic animals expressing a protein disclosed herein, vectors expressing such proteins.
    • 本发明提供抗动脉粥样硬化肽,所述肽与人apoA-I相比是两亲性螺旋肽,其特征在于具有以下8种特性中的至少4种:由脯氨酸连接的串联重复类A两亲性螺旋,其形成 脂质结合的最佳布置,具有双层膜稳定性质,刺激HIV-I Gp41诱导的细胞融合,刺激嗜中性粒细胞活化,刺激BSA诱导的含脂肪酸囊泡的裂解,刺激人胎盘乳糖合成,排出磷脂和细胞胆固醇 胆固醇负载细胞,并与HDL竞争结合细胞。 本发明还涉及药物组合物,表达本文公开的蛋白质的转基因动物,表达这种蛋白质的载体。
