The genomes of positive-sense (+) single-stranded RNA (ssRNA) viruses are believed to be subjected to a wide range of RNA modifications. In this study, we focused on the chikungunya virus (CHIKV) as a model (+) ssRNA virus to study the landscape of viral RNA modification in infected human cells. ...

Tick-borne encephalitis virus is an enveloped, pathogenic, RNA virus in the family Flaviviridae, genus Flavivirus. Viral particles are formed when the nucleocapsid, consisting of an RNA genome and multiple copies of the capsid protein, buds through the endoplasmic reticulum membrane and acquires ...

Despite the nuclear localization of the m6A machinery, the genomes of multiple exclusively-cytoplasmic RNA viruses, such as chikungunya (CHIKV) and dengue (DENV), are reported to be extensively m6A-modified. However, these findings are mostly based on m6A-seq, an antibody-dependent technique with...

Persistent infection of mosquito vectors is essential for the transmission of arboviruses, yet how these viruses produce sufficient progeny without compromising host cell fitness remains unclear. Arbovirus genomes exhibit suboptimal codon usage for both human and mosquito hosts, raising questions...

Porcine epidemic diarrhea virus (PEDV) causes acute intestinal disease in pigs and remains a major threat to the global swine industry due to its high morbidity and mortality in neonatal piglets. To investigate host metabolic alterations upon PEDV infection, we performed untargeted metabolomic pr...

ZIKV infection is associated with testicular damage and abnormal spermatogenesis. However, the molecular mechanisms underlying these pathogenic processes remain unclear. Here, we demonstrate that ZIKV disrupts Leydig cells' ability to produce testosterone, leading to decreased sperm counts and mo...
