A glance at subgenomic flavivirus RNAs and microRNAs in flavivirus infections [PDF]

Virology Journal, 2016
The family Flaviviridae comprises a wide variety of viruses that are distributed worldwide, some of which are associated with high rates of morbidity and mortality. There are neither vaccines nor antivirals for most flavivirus infections, reinforcing the importance of research on different aspects of the viral life cycle.

Mechanism through which retrocyclin targets flavivirus multiplication [PDF]

, 2021
Currently, there are no approved drugs for the treatment of flavivirus infection. Accordingly, we tested the inhibitory effects of the novel θ-defensin retrocyclin-101 (RC-101) against flavivirus infection, and investigated the mechanism underlying the ...

Neuroinvasive flavivirus infections [PDF]

Reviews in Medical Virology, 2011
SUMMARYFlaviviruses, including Dengue, West Nile, Japanese encephalitis, and Tick‐borne encephalitis virus, are major emerging human pathogens, affecting millions of individuals worldwide. Many clinically important flaviviruses elicit CNS diseases in infected hosts, including traditional “hemorrhagic” viruses, such as Dengue. This review focuses on the
