Article Abstract
Zika virus (ZIKV) and dengue virus (DENV) are two major mosquito-borne flaviviruses that pose a significant threat to the global public health system, particularly in tropical regions. The clinical outcomes related to these viral pathogens can vary from self-limiting asymptomatic infections to various forms of life-threatening pathological conditions such as haemorrhagic disorders. In addition to the direct effects of the viral pathogens, immune processes play also a significant function in the development of diseases mediated by ZIKV and DENV. Studing these processes is important for developing safer vaccines and targeted therapeutic strategies. These viruses have been reported to trigger various autoimmune disorders affecting different parts of human organ systems. It also has been shown that preexisting immunity to ZIKV or DENV can impact the outcome of subsequent infections caused by another virus. ZIKV and DENV infection can promote the development of autoimmune disorders by different mechanisms, such as molecular mimicry and autoantibody formation. The present review provides an overview of various autoimmune disorders associated with ZIKV and DENV infection and their potential underlying mechanisms.

Arboviral infections, particularly Dengue and Zika, continue to rise at an alarming rate, with both viruses declared global health emergencies in 2024 and 2016, respectively. The NS5 RNA-dependent RNA polymerase (RdRp) of dengue virus (DENV) and Zika virus (ZIKV) is highly conserved, making nucleoside-based RdRp inhibitors a promising strategy for antiviral development. While nucleoside analogs have shown strong clinical potential, challenges such as cell permeability, the efficiency of triphosphate conversion, degradation, and mitochondrial toxicity remain.

Background: Dengue and chikungunya are arboviral diseases with overlapping clinical characteristics. Dengue virus (DENV) is endemic in Colombia, and in 2014/2015, the chikungunya virus (CHIKV) caused an epidemic that resulted in over 350,000 cases. Since then, both viruses have been actively co-circulating.

Changes in global climate have contributed to increased tick and mosquito (vector) populations and subsequent vector-borne flavivirus infections in humans. This increase poses a threat to the safety of human-derived biologics such as cell and gene therapy. We conducted time-course transcriptomic and protein analyses to uncover host molecular factors driving the virulence of Zika virus (ZIKV) and Dengue virus (DENV) in relation to host defense mechanisms, as these viruses have caused recent flavivirus outbreaks.

The multiple epidemics of Zika virus (ZIKV) posed a substantial threat to public health. Clinical evidence suggests that ZIKV could break through the blood-brain, blood-placenta, and blood-testis barriers, leading to severe outcomes such as congenital malformations in newborns and Guillain-Barré syndrome in adults. Currently, there are no specific treatments for ZIKV infection.
