Enhancement of Zika virus pathogenesis by preexisting antiflavivirus immunity

TL;DR: Using convalescent plasma from DENV- and WNV-infected individuals, substantial enhancement of ZIKV infection in vitro was found that was mediated through immunoglobulin G engagement of Fcγ receptors, highlighting the need to exert great caution when designing flavivirus vaccines.
Journal ArticleDOI

Leveraging the antiviral type I interferon system as a first line of defense against SARS-CoV-2 pathogenicity.

TL;DR: In this paper, the authors investigated the dynamics of the systemic response to SARS-CoV-2 in hamsters by histological analysis and transcriptional profiling, and they found that the antiviral response with intranasal administration of recombinant IFN-I reduced viral disease, prevented transmission, and lowered inflammation in vivo.
Journal ArticleDOI

Non-cell-autonomous disruption of nuclear architecture as a potential cause of COVID-19-induced anosmia

TL;DR: In this paper , the authors show that SARS-CoV-2 infection causes widespread downregulation of olfactory receptors (ORs) and of their signaling components, followed by a dramatic reorganization of the neuronal nuclear architecture, which results in dissipation of genomic compartments harboring OR genes.
Journal ArticleDOI

Dengue Virus Immunity Increases Zika Virus-Induced Damage during Pregnancy

TL;DR: The presence of DENV‐specific antibodies in ZIKV‐infected pregnant mice significantly increased placental damage, fetal growth restriction, and fetal resorption and was associated with enhanced viral replication in the placenta that coincided with an increased frequency of infected trophoblasts.
