Human cytomegalovirus (HCMV) has evolved a number of mechanisms for long-term co-existence within its host. HCMV infects a wide range of cell types, including fibroblasts, epithelial cells, monocytes, macrophages, dendritic cells, and myeloid progenitor cells. Lytic infection, with the production of infectious progeny virions, occurs in differentiated cell types, while undifferentiated myeloid precursor cells are the primary site of latent infection. The outcome of HCMV infection depends partly on the cell type and differentiation state but is also influenced by the composition of the immune environment. In this review, we discuss the role of early interactions between HCMV and the host immune system, particularly cytokine and chemokine networks, that facilitate the establishment of lifelong latent infection. A better understanding of these cytokine signaling pathways could lead to novel therapeutic targets that might prevent latency or eradicate latently infected cells.
人类巨细胞病毒(HCMV)已经进化出多种机制以在其宿主内长期共存。HCMV可感染多种细胞类型,包括成纤维细胞、上皮细胞、单核细胞、巨噬细胞、树突状细胞和髓系祖细胞。有传染性子代病毒颗粒产生的裂解性感染发生在分化的细胞类型中,而未分化的髓系前体细胞是潜伏感染的主要部位。HCMV感染的结果部分取决于细胞类型和分化状态,但也受免疫环境组成的影响。在本综述中,我们讨论了HCMV与宿主免疫系统早期相互作用的作用,特别是细胞因子和趋化因子网络,它们有助于建立终身潜伏感染。更好地理解这些细胞因子信号通路可能会带来新的治疗靶点,有望预防潜伏感染或根除潜伏感染的细胞。
