Quantification of low-level Cytomegalovirus and Epstein-Barr virus DNAemia by digital PCR
CONCLUSION: dPCR can quantify low-level herpes virus DNAemia with CVs below 8%. Our results indicate that using serum-derived cell-free DNA and droplet-based dPCR is optimal for quantitating low-level viral DNAemia; however, plasma and chip-based approaches are acceptable alternatives and suitable for epidemiologic investigation.PMID:38184072 | DOI:10.1016/j.jviromet.2023.114876 (Source: Journal of Virological Methods)

Identification of a potent and specific retinoic acid-inducible gene 1 pathway activator as a Hepatitis B Virus antiviral through a novel cell-based reporter assay
J Virol Methods. 2024 Jan 2:114875. doi: 10.1016/j.jviromet.2023.114875. Online ahead of print.ABSTRACTChronic Hepatitis B Virus (HBV) infection remains a global burden. To identify small molecule RIG-I agonists as antivirals against HBV, we developed an HBV-pgRNA-based interferon-β (IFN-β) luciferase reporter assay with high level of assay sensitivity, specificity and robustness. Through HTS screening, lead compound (JJ#1) was identified to activate RIG-I signaling pathway by inducing TBK1 phosphorylation. Knockdown experiments demonstrated that JJ#1-induced retinoic acid-inducible gene 1 (RIG-I) signaling pathway activ...

A novel VP1-based enzyme-linked immunosorbent assay revealed widespread Enterovirus G infections in Guangxi, China
In this study, we developed a novel serological detection method based on the structural protein, VP1 of EV-G. The intra-assay and inter-assay coefficient variations were 3.2~8.9% and 2.6~8.0%, respectively. There was no cross-reaction of the VP1-based enzyme-linked immunosorbent assay (ELISA) with antisera against the other known porcine viruses. In addition, a comparison was made with other methods including the developed indirect ELISAs based on VP2 and VP3 proteins and western blot (WB) analysis, which demonstrated the reliability of the novel method. Using the VP1-based ELISA, we carried out the first seroepidemiologi...
