一、δ因子RNA的构造电镜下δ粒子外形直径约37nm,其RNA为1678个碱基的短链状,由环状核酸组成。以前尚未见有环状结构RNA病毒感染动物的类型,但此δ种因子可感染人且为环状结构。此外尚有某些特异结构,例如RNA染色体组为负链,具有多样副结构等。从结构上看δ因子可引起植物感染,类似类病毒或协生病毒(卫星病毒中的一种)。二、δ因子的肝内增殖Rizzetto用荧光抗体法检测肝活检组织中的病毒抗原时,发现肝细胞核内有荧光,因而自δ肝炎研究的开始就考虑到δ抗原蛋白存在于细胞核内,并认为可从
First, the structure of δ-factor RNA Electron microscopy δ particle diameter of about 37nm, the RNA is short-chained 1678 bases, composed of circular nucleic acids. The type of animal infected with the circular RNA virus has not been previously seen, but these delta factors can infect humans and are ring-shaped. In addition there are still some specific structures, such as RNA genome negative strand, with a variety of vice structure. Structurally, delta-factor can cause plant infections, like viroids or syngeneic viruses (one of the satellite viruses). Second, the intra-hepatic proliferation of δ factor Rizzetto fluorescent antibody method for detecting viral antigen in liver biopsies, the liver cells found in the fluorescence of the nucleus, and since the beginning of the study of δ-hepatitis δ antigen protein exists in the nucleus, and that From
