An atlas of chromatin landscape in KSHV-infected cells during de novo infection and reactivation.
Virology(2024)
摘要
Kaposi's sarcoma-associated herpesvirus (KSHV) is an oncogenic γ-herpesvirus with a double-stranded DNA capable of establishing latent infection in the host cell. During latency, only a limited number of viral genes are expressed in infected host cells, and that helps the virus to evade host immune cell response. During primary infection, the KSHV genome is chromatinized and maintained as an episome, which is tethered to the host chromosome via Latency Associated Nuclear Antigen (LANA). The KSHV episome undergoes the same chromatin modification with the host cell chromosome and, therefore, is regulated by various epigenetic modifications, such as DNA methylation, histone methylation, and histone acetylation. The KSHV genome is also organized in a spatiotemporal manner by forming genomic loops, which enable simultaneous and coordinated control of dynamic gene transcription, particularly during the lytic replication phase. The genome-wide approaches and advancing bioinformatic tools have increased the resolution of studies on the dynamic transcriptional control and our understanding of KSHV latency-lytic switch regulation. We will summarize our current understanding of the epigenetic gene regulation on the KSHV chromatin.
