  澳大利亚皇家墨尔本理工大学的研究人员8日说,他们研制的一种肽能杀死黑色素瘤细胞,将来有望以此为基础开发一种专门治疗皮肤癌的乳霜。

  研究人员将这种肽(即氨基酸短链)设计成能模仿黏液瘤病毒蛋白质的活动。此前的研究已表明,黏液瘤病毒能杀灭恶性黑色素瘤细胞。研究人员测试了这种肽的有效性,结果显示,它可以杀灭黑色素瘤细胞而不伤害正常的人类皮肤细胞。

  恶性黑色素瘤是致死率最高的皮肤癌。“澳大利亚的黑色素瘤发病率是世界最高的,每年超过1.1万例,”首席研究员塔格丽德·伊斯蒂万博士在声明中说。

  目前,治疗恶性黑色素瘤唯一有效的方法是早期诊断,并通过外科手术切除肿瘤及周边可能病变的健康皮肤。研究人员希望随着这项研究的深入,能研发出一种简单有效的治疗黑色素瘤的乳霜。
