Type I interferons govern Zika virus resistance of human macrophages and microglia

ABSTRACT: The role of the human type I interferon (IFN-I) system in restricting Zika virus (ZIKV) is uncertain. Here, genetic and pharmacological ablation of IFN-I signalling enhanced ZIKV replication and cytopathicity in macrophages and microglia, key cells in ZIKV transmission and pathogenesis. Thus, despite the extensive IFN-I countermeasures employed by ZIKV, IFN-I dictates the outcome of infection in macrophages. Therapeutic manipulation of the IFN-I system may bring clinical benefit in ZIKV.

Impact of Zika Virus on the Human Type I Interferon Osteoimmune Response

Project description:Background: The developing field of osteoimmunology supports importance of an interferon(IFN) response pathway in osteoblasts. Clarifying osteoblast-IFN interactions is important because IFN is used as salvage anti-tumor therapy but systemic toxicity is high with variable clinical results. In addition, osteoblast response to systemic bursts and disruptions of IFN pathways induced by viral infection may influence bone remodeling. ZIKA virus(ZIKV) infection impacts bone development in humans and IFN response in vitro. Consistently, initial evidence of permissivity to ZIKV has been reported in human osteoblasts. Hypothesis: Osteoblast-like Saos-2 cells are permissive to ZIKV and responsive to IFN. Methods: Multiple approaches were used to assess whether Saos-2 cells are permissive to ZIKV infection and exhibit IFN-mediated ZIKV suppression. Proteomic methods were used to evaluate impact of ZIKV and IFN on Saos-2 cells. Results: Evidence is presented confirming Saos-2 cells are permissive to ZIKV and support IFN-mediated suppression of ZIKV. ZIKV and IFN differentially impact the Saos-2 proteome. Both ZIKV and IFN suppress proteins associated with microcephaly/pseudo-TORCH syndrome (BI1, KIF20 and UBP18), and ZIKV induces potential entry factor PLVAP. Conclusions: Transient ZIKV infection influences osteoimmune state, and IFN and ZIKV activate distinct proteomes in Saos-2 cells, which could inform therapeutic, engineered, disruptions.

Inter and intra-lineage genetic diversity of Zika virus differs for American isolates

Project description:Zika virus (ZIKV) is a mosquito-transmitted positive-sense RNA virus in the family Flaviviridae. ZIKV infections are associated with neurodevelopmental deficiencies termed Congenital Zika Syndrome. ZIKV strains are grouped into three phylogenetic lineages: East African, West African, and Asian, which contains the American lineage. RNA virus genomes exist as genetically-related sequences. The heterogeneity of these viral populations is implicated in viral fitness, and genome diversity is correlated to virulence. This study examines genetic diversity of representative ZIKV strains from all lineages utilizing next generation sequencing (NGS). Inter-lineage diversity results indicate that ZIKV lineages differ broadly from each other; however, intra-lineage comparisons of American ZIKV strains isolated from human serum or placenta show differences in diversity when compared to ZIKVs from Asia and West Africa. This study describes the first comprehensive NGS analysis of all ZIKV lineages and posits that sub-consensus-level diversity may provide a framework for understanding ZIKV fitness during infection.

Zika virus antagonizes interferon response in patients and disrupts RIG-I-MAVS interaction through its CARD-TM domains

Project description:The emerging threat to global health associated with the Zika virus (ZIKV) epidemics and its link to severe complications highlights a growing need to better understand the pathogenic mechanisms of ZIKV. Accumulating evidence for a critical role of type I interferon (IFN-I) in protecting hosts from ZIKV infection lies in the findings that ZIKV has evolved various strategies to subvert the host defense line by counteracting the early IFN induction or subsequent IFN signaling. Yet, mechanisms underlying the counter-IFN capability of ZIKV and its proteins, which might contribute to the well-recognized broad cellular tropisms and persistence of ZIKV, remain to be fully understood. In our current study, using RNA sequencing-based transcriptional profiling from the whole blood cells isolated from patients acutely infected by ZIKV, we found that transcriptional signatures of antiviral interferon-stimulated genes and innate immune sensors was absent in ZIKV-infected patients presents inactive as compared to healthy donors, suggesting that ZIKV might suppress the induction of IFN-I during the natural infection process in human. Furthermore, utilizing cellular or extracellular analysis of molecular interaction in a ZIKV NS4A-overexpression system, or in the context of actual ZIKV infection, we have identified that ZIKV NS4A directly binds MAVS and thereby interrupts RIG-I/MAVS interaction through its CARD-TM domains, leading to attenuated production of IFN-I. Taken together, these findings originated from patient studies have added new knowledge and molecular details to our understanding regarding how ZIKV mediates suppression of the IFN-I system and may provide new basis for future development of anti-ZIKV strategies.

Constitutive expression and distinct properties of IFN-epsilon protect the female reproductive tract from Zika virus infection.

Project description:The female reproductive tract (FRT) is vulnerable to sexually transmitted infections and therefore a well-tuned immune surveillance system is crucial for maintaining a healthy FRT. However, our understanding of the factors that impact viral infection of the FRT and the host response are not well understood. In this work, we investigate the role of a hormonally regulated type I interferon, IFN epsilon, in control of Zika virus (ZIKV) infection of the FRT. We demonstrate that IFN epsilon has anti-ZIKV properties using a combination of IFN epsilon KO mice, blockade of endogenous IFN epsilon by neutralising Abs and rescue of IFN epsilon KO mice by recombinant IFN epsilon administered directly to the FRT.

Glioblastoma stem cells infected by ZIKA virus

Project description:We repoted the Glioblastoma stem cells(GSCs) infected by two strains of ZIKA virus, the Brazil and Dakar strains. The ZIKV was added into the medium of GSCs for 48 hours, the RNA was harvested after ZIKV infection. We found that the GSCs up-regulated the Type 1&2 interferons after infected by ZIKV
