摘要
朊粒的本质虽然是蛋白质,但从生命科学的观点看,却具有生命现象;同时朊粒具有传染性、致病性和增殖性,因此它又是一种独立存在的病原体.朊粒病毒能引发以慢性、进行性、退化性病变为特征的、致死性中枢神经系统疾病;但朊粒蛋白在人和动物体内普遍存在并具有一定的生理功能.对朊粒和朊粒蛋白的认识成为当前生命科学的研究热点之一.本文就当前对朊粒及朊粒蛋白的研究现状做一综述.
Although the essence of prion is the protein, but as for the life science vievpoint, it has the biological phenomena; Simulteaneously prion has the infectiong , the pathogenicity and the hyperphasia, therefore it also is one kind of pathogen that exists independently. Prion virus can cause fatral nervaus system disease which character is chronic, natural and degenerate pathlogical chang ; But prion protein exists universally in hunan beings and animals bodies and has some certoin physiological function. This artide makes a summary for the aorent research situation of prion and prion protein.
