Aim: Identifying genes and pathways involved in various stages of rotavirus infection could facilitate the mapping of the interactions between the virus and host. Materials & methods: Weighted gene co-expression network analysis (WGCNA) was employed to construct a co-expression network of genes identified by microarray analysis from samples from children with acute rotavirus infection. Results: Two specific modules were most related to rotavirus infection. The analysis of differentially expressed genes (DEGs) disclosed 393 DEGs between normal and infected individuals. Eighteen novel genes were shared between the modules. Conclusion: The WGCNA revealed novel modules, co-expressed genes and pathways involved in immune responses, cell death/degradation and the nervous system in acute rotavirus infection.

N6-methyladenosine (m6A) modification is the most pervasive type of RNA epigenetic modification in eukaryotes and the most common type of posttranscriptional modification of mRNA. m6A modification is a dynamic reversible process that can affect gene expression and play a crucial role in mRNA metabolism and multiple biological processes, ranging from RNA processing, nuclear export and RNA translation to decay. Meanwhile, much evidence has shown that m6A methylation regulates the life cycle of viruses and inhibits or promotes the development of various viruses. However, the mechanism of m6A methylation in virus-associated tumors has not been fully elucidated. This review highlights the role of m6A modification in various viruses to help establish new approaches for treating related diseases.

Aim: This study aimed to establish a simple whole-genome sequencing method for respiratory virus type A (RSVA) used in genomic epidemiological studies. Methods: Multiple primers were designed to amplify overlapping amplicons specific to RSVA. The amplicons were sequenced using Illumina and Nanopore sequencing platforms and the sequencing performances of the two platforms were also compared. Results: The study shows that the developed method could recover almost full genomes of RSVA when Ct values were less than 33 for clinical samples. Conclusion: In this study, a whole-genome sequencing method was developed for RSVA based on multiplex PCR.

Aim: This work aimed to investigate the antiviral activity of two 1,4-disubstituted-1,2,3-triazole derivatives (1 and 2) against Chikungunya virus (CHIKV) replication. Materials & methods: Cytotoxicity was analyzed using colorimetric assays and the antiviral potential was evaluated using plaque assays and computational tools. Results: Compound 2 showed antiviral activity against CHIKV 181-25 in BHK-21 and Vero cells. Also, this compound presented a higher activity against CHIKV BRA/RJ/18 in Vero cells, like compound 1. Compound 2 exhibited virucidal activity and inhibited virus entry while compound 1 inhibited virus release. Molecular docking suggested that these derivatives inhibit nsP1 protein while compound 1 may also target capsid protein. Conclusion: Both compounds exhibit promising antiviral activity against CHIKV by blocking different steps of virus replication.

Since the advent of highly active antiretroviral therapy, many efforts have been made to broaden the spectrum of possible regimens. Long-acting antiretrovirals, are particularly attractive, since they allow for less frequent dosing and can potentially overcome difficulties associated with daily tablet consumption, including the need for flexibility and privacy. In this article, we present a summary and update on currently available long-acting antiretrovirals and those under development and discuss issues related to their effective implementation.

Aim: To examine the expression of miR-203 and its target genes survivin and p63 in condyloma acuminatum (CA) and to determine their relationships with clinical recurrence. Methods: Case and control groups were assessed for general data and the expression levels of miR-203, survivin and p63. The case group received carbon dioxide laser treatment, had a 3-month follow-up period, and was then divided into recurrence and non-recurrence groups. The relevant data were analyzed using SPSS v. 25.0 software. Results: miR-203 was identified as an independent protective factor against the recurrence of CA, while wart number, survivin and p63 were independent risk factors for CA recurrence. Conclusion: miR-203 could be a specific clinical bioindicator for the prognosis and recurrence of CA.

Herpes virus is an enveloped virus with many glycoproteins essential for viral infection and immune evasion. Several glycosylation sites exist on the glycoproteins of herpes viruses, including N- and O-glycosylation sites. Glycosylation affects herpes virus infection and pathogenesis in different ways, including the attachment and entry of the herpes virus into host cells, virus replication and the host's immune function. This article summarized the current knowledge on the glycosylation of herpes virus envelope glycoproteins and its impact on viral infection and demonstrated several applications of glycosylation inhibitors.

Neurotropic viruses target the central nervous system through various mechanisms: they have the potential to modulate synaptic plasticity, causing cognitive impairments by blocking N-methyl d-aspartate receptors; they alter the Ca2+ ion-signaling pathways modulating long-term potentiation, leading to a severe inflammatory response in brain cells, increased reactive oxygen species and lipid peroxidation through mitochondria and peroxisomes. Inflammatory pathways have a key role in modulating the plasticity of neurons, linked to numerous neurological disorders. Advanced neuroimaging techniques facilitate the early diagnosis of impaired synaptic function in viral infections and neurodegenerative disorders. Here we discuss the understanding of the interplay between neurotropic viral infections and their effects on synaptic plasticity and diagnosis through neuroimaging techniques.
