Zoonotic orthopoxvirus infections continue to represent a threat to human health. The disease caused by distinct orthopoxviruses differs in terms of symptoms and severity, which may be explained by the unique repertoire of virus factors that modulate the host’s immune response and cellular machinery. We report here on the construction of recombinant cowpox viruses (CPXV) which either lack the host range factor p28 completely or express truncated variants of p28. We show that p28 is essential for CPXV replication in macrophages of human or mouse origin and that the C-terminal RING finger domain of p28 is necessary to allow CPXV replication in macrophages.

牛痘病毒在巨噬细胞中的复制依赖于宿主范围因子 p28/N1R

人畜共患正痘病毒感染继续对人类健康构成威胁。由不同的正痘病毒引起的疾病在症状和严重程度方面有所不同,这可能是由调节宿主免疫反应和细胞机制的病毒因子的独特组成来解释的。我们在此报告重组牛痘病毒 (CPXV) 的构建,该病毒完全缺乏宿主范围因子 p28 或表达 p28 的截短变体。我们表明 p28 对于 CPXV 在人类或小鼠来源的巨噬细胞中的复制是必不可少的,并且 p28 的 C 末端 RING 指结构域对于允许 CPXV 在巨噬细胞中的复制是必需的。
