Viruses with RNA Genomes01:29

Viruses with RNA Genomes

3
RNA viruses are categorized into positive-strand, negative-strand, or double-stranded groups based on their genomic structure and replication mechanisms. This classification dictates how they exploit host cellular machinery for protein synthesis and replication. Some RNA viruses also utilize reverse transcription as part of their life cycle, further diversifying their replication strategies.Positive-Strand RNA VirusesPositive-strand RNA viruses have genomes that function directly as messenger...

概括

肝炎E病毒 (HEV) 的复制取决于宿主细胞的葡萄糖和谷氨酸代谢,特别是胺生物合成途径 (HBP). 抑制糖溶解,谷氨酸溶解或HBP组件可以显著减少HEV复制.
