Fetal Brain lesions after subcutaneous inoculation of Zika virus in a pregnant nonhuman primate

ABSTRACT: ZIKV was inoculated (strain FSS13025, Cambodia 2010) subcutaneously at five separate locations on the forearms, each with 107 plaque-forming units (PFU) into a healthy pregnant pigtail macaque at 119 days gestation (~28 weeks human pregnancy) to test directly whether ZIKV causes fetal brain injury.

Immunologic Control of Zika Virus in Rhesus Monkeys

Project description:Zika virus (ZIKV) is responsible for a major current outbreak in the Americas and has been causally associated with fetal microcephaly as well as Guillain-Barre syndrome in adults. However, the immune responses associated with controlling ZIKV replication remain poorly characterized. Here we report a detailed analysis of innate and adaptive immune responses following ZIKV infection in 16 rhesus monkeys. A robust proinflammatory innate immune response was observed within the first few days of infection, including upregulation of type 1 interferon, which correlated directly with viral loads. Immunomodulatory pathways, including IL-10 and TGF-β, were also upregulated. ZIKV-specific neutralizing antibodies emerged rapidly by day 7 and correlated inversely with viral loads, which were undetectable in peripheral blood by day 6-10. In contrast, virus replication persisted in cerebrospinal fluid (CSF) for at least 21-42 days in 75% (3 of 4) of the monkeys that received the lowest dose of ZIKV tested, and ZIKV-specific antibodies were essentially undetectable in CSF. These data suggest that antibodies play a critical role in the rapid control of acute viremia in the periphery but were largely excluded from the central nervous system, allowing viral persistence at this immuonoprivileged site. 16 outbred, Indian-origin, adult male and female rhesus monkeys (Macaca mulatta) were included in this study. All monkeys were housed at Bioqual, Rockville, MD. Animals were infected with 103-106 pfu (106-109 vp) of our ZIKV-BR or ZIKV-PR challenge stocks by the s.q. route (N=2/group). All animal studies were approved by the appropriate Institutional Animal Care and Use Committee (IACUC).

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.

Using next generation sequencing to study the genetic diversity of candidate live attenuated Zika vaccines

Project description:Zika virus (ZIKV) is a mosquito-transmitted positive-sense RNA virus in the family Flaviviridae. Candidate live-attenuated vaccine (LAV) viruses with engineered deletions in the 3’UTR provide immunity and protection in animal models of ZIKV infection, and phenotypic studies show that LAVs retain protective abilities following in vitro passage. The present study investigates the genetic diversity of wild-type (WT) parent ZIKV and its candidate LAVs using next generation sequencing analysis of five sequential in vitro passages. ZIKV RNA from was transfected into Vero cells, incubated for nine days, harvested, and clarified by centrifugation to generate passage 0 (P0) ZIKV infectious clones. Subsequently, P0 ZIKVs were blind-passaged into fresh cultures to generate P1, then serially through P5. P1-P5 stocks were harvested from cell media at 4-5 days post-infection. ZIKV RNA from 3’UTR deletion mutants were transfected into Vero cells, incubated for nine days, harvested, and clarified by centrifugation to generate passage 0 (P0) ZIKV infectious clones. Subsequently, P0 ZIKVs were blind-passaged into fresh cultures to generate P1, then serially through P5. P1-P5 stocks were harvested from cell media at 4-5 days post-infection. Genetic diversity of the viruses were assessed by evaluating both the variability (or uncertainty) at each nucleotide position was determined using Shannon entropy calculations and identified single nucleotide variants (SNVs). The results showed both the parental WT and LAV derivatives increase in genetic diversity with evidence of adaptation following passage.

Male Germ Cells Support Long-Term Propagation of Zika Virus

Project description:Evidence of male-to-female sexual transmission of Zika virus (ZIKV) and viral RNA in semen and sperm months after infection support a potential role for testicular cells in ZIKV propagation. Here, we demonstrate that germ cells (GC) are most susceptible to ZIKV. We find that only GC infected by ZIKV, but not those infected by dengue fever (DENV) and yellow fever virus (YFV), produce high levels of infectious virus. This observation coincides with decreased expression of interferon-stimulated gene Ifi44l in ZIKV-infected GC and over-expression of Ifi44l results in reduced ZIKV production. Using primary human testicular tissue, we demonstrate that human GC are also permissive for ZIKV infection and production. Finally, we identify berberine chloride as a potent inhibitor of ZIKV infection in both murine and human testes. Together, these studies identify a potential cellular source for propagation of ZIKV in testes and a candidate drug for preventing sexual transmission of ZIKV.

Immunoprofiling of CD14+ blood monocytes upon Zika virus infection

Project description:Blood CD14+ monocytes are the frontline immunomodulators categorized into classical, intermediate or non-classical subsets, subsequently differentiating into M1 pro- or M2 anti-inflammatory macrophages upon stimulation. While Zika virus (ZIKV) rapidly establishes viremia, the target cells and immune responses, particularly during pregnancy, remain elusive. Furthermore, it is unknown whether African- and Asian-lineage ZIKV have different phenotypic impacts on host immune responses. Using human blood infection, we identified CD14+ monocytes as the primary target for African- or Asian-lineage ZIKV infection. When immunoprofiles of human blood infected with ZIKV were compared, a classical/intermediate monocyte-mediated M1-skewed inflammation by African-lineage ZIKV infection was observed, in contrast to a non-classical monocyte-mediated M2-skewed immunosuppression by Asian-lineage ZIKV infection. Importantly, infection of pregnant women’s blood revealed enhanced susceptibility to ZIKV infection. Specifically, Asian-lineage ZIKV infection of pregnant women’s blood led to an exacerbated M2-skewed immunosuppression of non-classical monocytes in conjunction with global suppression of type I interferon-signaling pathway and an aberrant expression of host genes associated with pregnancy complications. 30 ZIKV+ sera from symptomatic pregnant patients also showed elevated levels of M2-skewed immunosuppressive cytokines and pregnancy complication-associated fibronectin-1. This study demonstrates the differential immunomodulatory responses of blood monocytes, particularly during pregnancy, upon infection with different lineages of ZIKV.
