RNA adopts 3D structures that confer varied functional roles in human biology and dysfunction in disease. Approaches to therapeutically target RNA structures with small molecules are being actively pursued, aided by key advances in the field including the development of computational tools that predict ...
在慢乙肝患者抗病毒治疗过程中监测血清HBV RNA水平能够真实反映cccDNA转录活性状态,对优化CHB患者的治疗策略以及辅助临床停药标准的判定有着重要的意义,尤其是经过抗病毒治疗后HBV DNA阴转的患者,可通过HBV RNA持续进行肝内病毒活性监测[6]。 除此以外,血清HBV RNA在预测肝...
Figure 01: DNA Virus Moreover, these viruses are usually large, icosahedral, enveloped in lipoproteins, and they do not have polymerase enzymes. Whenever they replicate, they use either host DNA polymerases or virally encoded DNA polymerases. Moreover, they cause latent infections. Some examples ...
2 Overview of RNA virus biology RNA viruses are very simple entities with small genomes that vary in length from ~ 2 to ~ 32 kb, depending on the virus. Thus, they have very limited coding capacity and so, like DNA viruses, they are obligate intracellular parasites, depending on a host ...
Studies on protein-encoding DNA andRNA virusesand nonprotein-encodingviroidsmake a significant contribution to the understanding of macromolecular cell-to-cell and long-distance movement in plants. Most plant viruses have an RNA genome (vRNA), which is usually single stranded. RNA viruses are an ...
病毒分为DNA病毒和RNA病毒。DNA病毒被TLRs (toll样受体)和cGAS(环GMP-AMP合成酶)识别。另一方面,RNA病毒被RLRs (RIG-I样受体)识别,如RIG-I, MDA5和LGP2。TLRs和RLRs都属于模式识别受体(PRRs)。由这些PRRs触发的先天免疫信号导致炎症介质的转录表达,协调病原体和受感染细胞的消除。
