Abstract
© 2019, Springer-Verlag GmbH Austria, part of Springer Nature. Zika virus (ZIKV) has been endemic in Southeast Asian countries for several years, but the presence of the virus has not been associated with significant outbreaks of infection unlike other countries around the world where the Asian lineage ZIKV was introduced recently. However, few studies have been undertaken using the endemic virus. The Thai isolate was shown to have a similar tissue tropism to an African isolate of ZIKV, albeit that the Thai isolate infected cells at a lower level as compared to the African isolate. To further understand the pathogenesis of the Thai isolate, a 2D-gel proteomic analysis was undertaken of ZIKV infected LLC-MK2 cells. Seven proteins (superoxide dismutase [Mn], peroxiredoxin 2, ATP synthase subunit alpha, annexin A5 and annexin A1, carnitine o-palmitoyltransferase 2 and cytoskeleton-associated protein 2) were identified as differentially regulated. Of four proteins selected for validation, three (superoxide dismutase [Mn], peroxiredoxin 2, ATP synthase subunit alpha, and annexin A1) were shown to be differentially regulated at both the transcriptional and translational levels. The proteins identified were primarily involved in energy production both directly, and indirectly through mediation of autophagy, as well as in the response to oxidative stress, possibly occurring as a consequence of increased energy production. This study provides further new information on the pathogenesis of ZIKV.
