Calderón-Peláez MA, Maradei Anaya SJ, Bedoya-Rodríguez IJ, González-Ipuz KG, Vera-Palacios D, Buitrago IV, Castellanos JE, Velandia-Romero ML. Zika Virus: A Neurotropic Warrior against High-Grade Gliomas-Unveiling Its Potential for Oncolytic Virotherapy. Viruses 2024; 16:561. [PMID: 38675903 PMCID: PMC11055012 DOI: 10.3390/v16040561] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/12/2024] [Revised: 01/29/2024] [Accepted: 01/29/2024] [Indexed: 04/28/2024] Open
Abstract
Gliomas account for approximately 75-80% of all malignant primary tumors in the central nervous system (CNS), with glioblastoma multiforme (GBM) considered the deadliest. Despite aggressive treatment involving a combination of chemotherapy, radiotherapy, and surgical intervention, patients with GBM have limited survival rates of 2 to 5 years, accompanied by a significant decline in their quality of life. In recent years, novel management strategies have emerged, such as immunotherapy, which includes the development of vaccines or T cells with chimeric antigen receptors, and oncolytic virotherapy (OVT), wherein wild type (WT) or genetically modified viruses are utilized to selectively lyse tumor cells. In vitro and in vivo studies have shown that the Zika virus (ZIKV) can infect glioma cells and induce a robust oncolytic activity. Consequently, interest in exploring this virus as a potential oncolytic virus (OV) for high-grade gliomas has surged. Given that ZIKV actively circulates in Colombia, evaluating its neurotropic and oncolytic capabilities holds considerable national and international importance, as it may emerge as an alternative for treating highly complex gliomas. Therefore, this literature review outlines the generalities of GBM, the factors determining ZIKV's specific tropism for nervous tissue, and its oncolytic capacity. Additionally, we briefly present the progress in preclinical studies supporting the use of ZIKV as an OVT for gliomas.

Abstract
Neurons forming the human brain are generated during embryonic development by neural stem and progenitor cells via a process called neurogenesis. A crucial feature contributing to neural stem cell morphological and functional heterogeneity is cell polarity, defined as asymmetric distribution of cellular components. Cell polarity is built and maintained thanks to the interplay between polarity proteins and polarity-generating organelles, such as the endoplasmic reticulum (ER) and the Golgi apparatus (GA). ER and GA affect the distribution of membrane components and work as a hub where glycans are added to nascent proteins and lipids. In the last decades our knowledge on the role of polarity in neural stem and progenitor cells have increased tremendously. However, the role of traffic and associated glycosylation in neural stem and progenitor cells is still relatively underexplored. In this review, we discuss the link between cell polarity, architecture, identity and intracellular traffic, and highlight how studies on neurons have shaped our knowledge and conceptual framework on traffic and polarity. We will then conclude by discussing how a group of rare diseases, called congenital disorders of glycosylation (CDG) offers the unique opportunity to study the contribution of traffic and glycosylation in the context of neurodevelopment.

Abstract
Zika virus (ZIKV) is a mosquito-borne flavivirus associated with several neurodevelopmental outcomes after in utero infection. Here, we studied a congenital ZIKV infection model with immunocompetent Wistar rats, able to predict disabilities and that could pave the way for proposing new effective therapies. We identified neurodevelopmental milestones disabilities in congenital ZIKV animals. Also, on 22nd postnatal day (PND), blood-brain barrier (BBB) proteins disturbances were detected in the hippocampus with immunocontent reduction of β_Catenin, Occludin and Conexin-43. Besides, oxidative stress imbalance on hippocampus and cortex were identified, without neuronal reduction in these structures. In conclusion, even without pups' microcephaly-like phenotype, congenital ZIKV infection resulted in neurobehavioral dysfunction associated with BBB and oxidative stress disturbances in young rats. Therefore, our findings highlighted the multiple impact of the congenital ZIKV infection on the neurodevelopment, which reinforces the continuity of studies to understand the spectrum of this impairment and to provide support to future treatment development for patients affected by congenital ZIKV.

Abstract
Microcephaly is a neurological condition characterized by anomalies in the growth of the cranial circumference. This study aims to examine the association between sociodemographic and clinical variables and the occurrence of secondary microcephaly in newborns in Brazil. It also aims to investigate the association between this congenital anomaly and teratogenic infections. This research adopts an observational approach with an ecological, descriptive, and analytical design. The sample includes infants aged ≤28 days and registered in the country's Live Births Information System from January 2015 to December 2021. Newborns were categorized into G1, consisting of newborns with one of the three infections (Zika, toxoplasmosis, or syphilis), and G2, consisting of newborns with two of the three infections. A total of 1513 samples were analyzed and divided into two groups: one infection (syphilis n = 423; toxoplasmosis n = 295; or Zika n = 739) and two infections (n = 56). The northeastern region of Brazil has the highest prevalence of microcephaly. Regarding the population profile, the Zika virus infection is more common among white mothers, while the syphilis infection is more common among black mothers. Among newborns with microcephaly, boys have a lower prevalence of toxoplasmosis infection, while girls have a lower prevalence of Zika virus infection. This study provides pertinent information on each infection and contributes to the epidemiologic understanding of the association between teratogenic infections and microcephaly.

Abstract
Sexual transmission of Zika virus (ZIKV) is associated with virus persistence in the testes and shedding in the seminal fluid for months after recovery. We previously demonstrated that ZIKV can establish long-term replication without causing cytotoxicity in human Sertoli cells (SC), responsible for maintaining the immune privileged compartment of seminiferous tubules. Functional gene expression analyses also predicted activation of multiple virus sensing pathways including TLR3, RIG-I, and MDA5. Here, we elucidated which of the RNA virus sensing receptors play a decisive role in restricting ZIKV replication. We show that both poly I:C and IFN-β treatment induced a robust antiviral state and reduced ZIKV replication significantly, suggesting that virus sensing and antiviral signaling are functional in SC. Silencing of TLR3, 7, and 9 did not affect virus replication kinetics; however, both RIG-I and MDA5 played a synergistic role in inducing an anti-ZIKV response. Further, the impact of SC-specific immunosuppressive pathways that collectively regulate SC function, specifically the TGF-β superfamily members, TGF-β, Activin A, and BMP6, on ZIKV replication was investigated. While ZIKV did not modulate the expression of TGF-β and Activin A, BMP6 signaling was suppressed at later stages of infection. Notably, treatment with BMP6 increased IFN-β, p-IRF3, and p-STAT1 levels, and expression of key interferon-stimulated genes including MDA5, suggesting that BMP6 enhances antiviral response in SC. Collectively, this study further delineates the key role of the RIG-I-like receptors in sensing ZIKV in SC, and reveals a novel role of BMP6 in modulating innate immune and antiviral response in the testes.

Abstract
First isolated in 1947, the Zika virus was initially connected only to limited or sporadic human infections. In late 2015, the temporal clustering of a Zika outbreak and microcephaly in newborn babies from northeastern Brazil, and the identification of a causal link between the two, led to the characterization of the congenital Zika syndrome. In the wake of the epidemic, several countries from Latin America advised women to postpone pregnancies for periods ranging from six months to two years. These recommendations initiated critical conversations about the challenges of implementing them in societies with limited access to contraception, widespread socioeconomic inequalities, and high rates of unplanned and adolescent pregnancies. The messaging targeted exclusively women, despite a high prevalence of imbalances in the relationship power, and addressed all women as a group, failing to recognize that the decision to postpone pregnancies will impact different women in different ways, depending on their age at the time. Finally, in several countries affected by the Zika epidemic, due to restrictive reproductive policies, legally terminating a pregnancy is no longer an option even at the earliest time when brain malformations as part of the congenital Zika syndrome can be detected by ultrasonography. The virus continued to circulate after 2016 in several countries. Climate change models predict an expansion of the geographical area where local Zika transmission may occur, indicating that the interface between the virus, teratogenesis, and reproductive rights is a topic of considerable interest for medicine, social sciences, and public health for years to come.

Abstract
Ocular viral infections are common and widespread globally. These infectious diseases are a major cause of acute red eyes and vision loss. The eye and its nearby tissues can be infected by several viral agents, causing infections with a short course and limited ocular implications or a long clinical progression and serious consequences for the function and structure of the ocular region. Several surveillance studies underline the increased emergence of drug resistance among pathogenic viral strains, limiting treatment options for these infections. Currently, in the event of resistant infections, topical or systemic corticosteroids are useful in the management of associated immune reactions in the eye, which contribute to ocular dysfunction. Many cases of viral eye infections are misdiagnosed as being of bacterial origin. In these cases, therapy begins late and is not targeted at the actual cause of the infection, often leading to severe ocular compromises, such as corneal infiltrates, conjunctival scarring, and reduced visual acuity. The present study aims at a better understanding of the viral pathogens that cause eye infections, along with the treatment options available.

Is the ZIKV Congenital Syndrome and Microcephaly Due to Syndemism with Latent Virus Coinfection? Viruses 2021; 13:v13040669.

Abstract
The emergence of the Zika virus (ZIKV) mirrors its evolutionary nature and, thus, its ability to grow in diversity or complexity (i.e., related to genome, host response, environment changes, tropism, and pathogenicity), leading to it recently joining the circle of closed congenital pathogens. The causal relation of ZIKV to microcephaly is still a much-debated issue. The identification of outbreak foci being in certain endemic urban areas characterized by a high-density population emphasizes that mixed infections might spearhead the recent appearance of a wide range of diseases that were initially attributed to ZIKV. Globally, such coinfections may have both positive and negative effects on viral replication, tropism, host response, and the viral genome. In other words, the possibility of coinfection may necessitate revisiting what is considered to be known regarding the pathogenesis and epidemiology of ZIKV diseases. ZIKV viral coinfections are already being reported with other arboviruses (e.g., chikungunya virus (CHIKV) and dengue virus (DENV)) as well as congenital pathogens (e.g., human immunodeficiency virus (HIV) and cytomegalovirus (HCMV)). However, descriptions of human latent viruses and their impacts on ZIKV disease outcomes in hosts are currently lacking. This review proposes to select some interesting human latent viruses (i.e., herpes simplex virus 2 (HSV-2), Epstein-Barr virus (EBV), human herpesvirus 6 (HHV-6), human parvovirus B19 (B19V), and human papillomavirus (HPV)), whose virological features and co-exposition with ZIKV may provide evidence of the syndemism process, shedding some light on the emergence of the ZIKV-induced global congenital syndrome in South America.

Abstract
Introduction Flaviviridae family belongs to the Spondweni serocomplex, which is mainly transmitted by vectors from the Aedes genus. Zika virus (ZIKV) is part of this genus. It was initially reported in Brazil in December 2014 as an unknown acute generalized exanthematous disease and was subsequently identified as ZIKV infection. ZIKV became widespread all over Brazil and was linked with potential cases of microcephaly. Case report We report a case of a 28-year-old Colombian woman, who came to the Obstetric Department with an assumed conglomerate of fetal abnormalities detected via ultrasonography, which was performed at 29.5 weeks of gestation. The patient presented with multiple abnormalities, which range from a suggested Arnold–Chiari malformation, compromising the lateral and third ventricles, liver calcifications, bilateral pyelocalic dilatations, other brain anomalies, and microcephaly. At 12 weeks of gestation, the vertical transmission of ZIKV was suspected. At 38.6 weeks of gestation, the newborn was delivered, with the weight in the 10th percentile (3,180 g), height in the 10th percentile (48 cm), and cephalic circumference under the 2nd percentile (31 cm). Due to the physical findings, brain magnetic resonance imaging (MRI) was performed, revealing a small and deviated brain stem, narrowing of the posterior fossa, a giant posterior fossa cyst with ventricular dilatation, a severe cortical and white matter thinning, cerebellar vermis with hypoplasia, and superior and lateral displacement of the cerebellum. In addition, hydrocephalus was displayed by the axial sequence, and the cerebral cortex was also compromised with lissencephaly. Schizencephaly was found with left frontal open-lip, and no intracranial calcifications were found. Two novel heterozygous nonsense mutations were identified using whole-exome sequencing, and both are located in exon 8 under the affection of ZIKV congenital syndrome (CZS) that produced a premature stop codon resulting in the truncation of the cyclin-dependent kinase 5 regulatory subunit-associated protein 2 (CDK5RAP2) protein. Conclusion We used molecular and microbiological assessments to report the initial case of vertically transmitted ZIKV infection with congenital syndrome associated with a neurological syndrome, where a mutation in the CDK5RAP2 gene was also identified. The CDK5RAP2 gene encodes a pericentriolar protein that intervenes in microtubule nucleation and centriole attachment. Diallelic mutation has previously been associated with primary microcephaly.

Abstract
Zika virus (ZIKV) has emerged as a particularly notorious mosquito-borne flavivirus, which can lead to a devastating congenital syndrome in the fetuses of pregnant mothers (e.g., microcephaly, spasticity, craniofacial disproportion, miscarriage, and ocular abnormalities) and cause the autoimmune disorder Guillain-Barre' syndrome of adults. Due to its severity and rapid dispersal over several continents, ZIKV has been acknowledged to be a global health concern by the World Health Organization. Unfortunately, the ZIKV has recently resurged in India with the potential for devastating effects. Researchers from all around the world have worked tirelessly to develop effective detection strategies and vaccines for the prevention and control of ZIKV infection. In this review, we comprehensively summarize the most recent research into ZIKV, including the structural biology and evolution, historical overview, pathogenesis, symptoms, and transmission. We then focus on the detection strategies for ZIKV, including viral isolation, serological assays, molecular assays, sensing methods, reverse transcription loop mediated isothermal amplification, transcription-mediated amplification technology, reverse transcription strand invasion based amplification, bioplasmonic paper-based device, and reverse transcription isothermal recombinase polymerase amplification. To conclude, we examine the limitations of currently available strategies for the detection of ZIKV, and outline future opportunities and research challenges.

Congenital Malformations in Sea Turtles: Puzzling Interplay between Genes and Environment. Animals (Basel) 2021; 11:ani11020444. [PMID: 33567785 PMCID: PMC7915190 DOI: 10.3390/ani11020444] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/23/2020] [Revised: 02/02/2021] [Accepted: 02/03/2021] [Indexed: 12/28/2022] Open
Abstract
Simple Summary Congenital malformations can lead to embryonic mortality in many species, and sea turtles are no exception. Genetic and/or environmental alterations occur during early development in the embryo, and may produce aberrant phenotypes, many of which are incompatible with life. Causes of malformations are multifactorial; genetic factors may include mutations, chromosomal aberrations, and inbreeding effects, whereas non-genetic factors may include nutrition, hyperthermia, low moisture, radiation, and contamination. It is possible to monitor and control some of these factors (such as temperature and humidity) in nesting beaches, and toxic compounds in feeding areas, which can be transferred to the embryo through their lipophilic properties. In this review, we describe possible causes of different types of malformations observed in sea turtle embryos, as well as some actions that may help reduce embryonic mortality. Abstract The completion of embryonic development depends, in part, on the interplay between genetic factors and environmental conditions, and any alteration during development may affect embryonic genetic and epigenetic regulatory pathways leading to congenital malformations, which are mostly incompatible with life. Oviparous reptiles, such as sea turtles, that produce numerous eggs in a clutch that is buried on the beach provide an opportunity to study embryonic mortality associated with malformations that occur at different times during development, or that prevent the hatchling from emerging from the nest. In sea turtles, the presence of congenital malformations frequently leads to mortality. A few years ago, a detailed study was performed on external congenital malformations in three species of sea turtles from the Mexican Pacific and Caribbean coasts, the hawksbill turtle, Eretmochelys imbricata (n = 23,559 eggs), the green turtle, Chelonia mydas (n = 17,690 eggs), and the olive ridley, Lepidochelys olivacea (n = 20,257 eggs), finding 63 types of congenital malformations, of which 38 were new reports. Of the three species, the olive ridley showed a higher incidence of severe anomalies in the craniofacial region (49%), indicating alterations of early developmental pathways; however, several malformations were also observed in the body, including defects in the carapace (45%) and limbs (33%), as well as pigmentation disorders (20%), indicating that deviations occurred during the middle and later stages of development. Although intrinsic factors (i.e., genetic mutations or epigenetic modifications) are difficult to monitor in the field, some environmental factors (such as the incubation temperature, humidity, and probably the status of feeding areas) are, to some extent, less difficult to monitor and/or control. In this review, we describe the aetiology of different malformations observed in sea turtle embryos, and provide some actions that can reduce embryonic mortality.

Zika virus infection induces endoplasmic reticulum stress and apoptosis in placental trophoblasts. Cell Death Discov 2021; 7:24.

Abstract
Zika virus (ZIKV) infection to a pregnant woman can be vertically transmitted to the fetus via the placenta leading to Congenital Zika syndrome. This is characterized by microcephaly, retinal defects, and intrauterine growth retardation. ZIKV induces placental trophoblast apoptosis leading to severe abnormalities in the growth and development of the fetus. However, the molecular mechanism behind ZIKV-induced apoptosis in placental trophoblasts remains unclear. We hypothesize that ZIKV infection induces endoplasmic reticulum (ER) stress in the trophoblasts, and sustained ER stress results in apoptosis. HTR-8 (HTR-8/SVneo), a human normal immortalized trophoblast cell and human choriocarcinoma-derived cell lines (JEG-3 and JAR) were infected with ZIKV. Biochemical and structural markers of apoptosis like caspase 3/7 activity and percent apoptotic nuclear morphological changes, respectively were assessed. ZIKV infection in placental trophoblasts showed an increase in the levels of CHOP mRNA and protein expression, which is an inducer of apoptosis. Next, we also observed increased levels of ER stress markers such as phosphorylated forms of inositol-requiring transmembrane kinase/endoribonuclease 1α (P-IRE1α), and its downstream target, the spliced form of XBP1 mRNA, phosphorylated eukaryotic initiation factor 2α (P-eIF2α), and activation of cJun N-terminal Kinase (JNK) and p38 mitogen activated protein kinase (MAPK) after 16-24 h of ZIKV infection in trophoblasts. Inhibition of JNK or pan-caspases using small molecule inhibitors significantly prevented ZIKV-induced apoptosis in trophoblasts. Further, JNK inhibition also reduced XBP1 mRNA splicing and viral E protein staining in ZIKV infected cells. In conclusion, the mechanism of ZIKV-induced placental trophoblast apoptosis involves the activation of ER stress and JNK activation, and the inhibition of JNK dramatically prevents ZIKV-induced trophoblast apoptosis.

Evaluation of the frequency of neuroimaging findings in congenital infection by Zika virus and differences between computed tomography and magnetic resonance imaging in the detection of alterations. Rev Soc Bras Med Trop 2020; 53:e20190557. [PMID: 33263680 PMCID: PMC7723366 DOI: 10.1590/0037-8682-0557-2019] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/09/2019] [Accepted: 10/23/2020] [Indexed: 11/21/2022] Open
Abstract
INTRODUCTION Congenital infection by the Zika virus (ZIKV) is responsible for severe abnormalities in the development of the central nervous system. The aim of this study was to evaluate and compare the ability of computed tomography (CT) and magnetic resonance (MR) to detect patterns of involvement of the central nervous system in congenital ZIKV syndrome. METHODS We retrospectively analyzed CT and MR images from 34 patients with congenital ZIKV syndrome and evaluated the differences between the two methods in detecting alterations. RESULTS The predominant radiographic finding was a simplified gyral pattern, present in 97% of cases. The second most common finding was the presence of calcifications (94.1%), followed by ventriculomegaly (85.3%), dysgenesis of the corpus callosum (85.3%), craniofacial disproportion and redundant scalp (79.4%), complete opercular opening (79.4%), occipital prominence (44.1%), cerebellar hypoplasia (14.7%), and pontine hypoplasia (11.8%). The gyral pattern was extensively simplified in most cases, and calcifications were located predominantly at the cortical-subcortical junction. CT was able to better identify calcifications (94.1% × 88.2%), while MRI presented better spatial resolution for the characterization of gyral pattern (97% × 94.1%) and corpus callosum dysgenesis (85.3% × 79.4%). CONCLUSIONS Although congenital ZIKV syndrome does not present pathognomonic neuroimaging findings, some aspects, such as calcifications at the cortical-subcortical junction, especially when associated with compatible clinical and laboratory findings, are suggestive of intrauterine ZIKV infection.

Abstract
INTRODUCTION Having verified the true association between the Zika virus and the occurrence of microcephaly, studies were conducted to evaluate the effects of the infection on fetal development. Congenital Zika virus syndrome is a currently known condition but little addressed regarding speech, language, and hearing disorders in children. OBJECTIVE To conduct a systematic review of speech, language, and hearing disorders in children with congenital Zika virus syndrome. METHODS This systematic review followed the PRISMA instructions and the Joanna Briggs Institute guidelines, and it was registered in PROSPERO (CRD42018111764). The databases consulted were Cochrane, SciELO, PubMed, LILACS, Scopus, Web of Science, and ScienceDirect. OpenGrey and OpenThesis were used to partially capture the "grey literature". Observational studies of children with microcephaly due to congenital Zika virus syndrome were included. The risk of bias was analyzed using the 2017 Joanna Briggs Institute. RESULTS 707 records were obtained and, after excluding the duplicates, 644 studies remained. After applying the inclusion criteria, 24 articles were considered eligible. Children with congenital Zika virus syndrome presented abnormal persistence of primitive reflexes (94.7%), impaired cognitive development (95.1%), delayed neuropsychomotor development (between 92.8 and 100%), hypertonia (between 74.7% and 90.1%), impaired language development (between 68.42% and 100%), retrognathia (38.6%), craniofacial disproportion (between 32.9% and 95.8%), altered tongue frenulum (between 30% and 36.36%), the absence of stapedial reflexes (27.3%), dysphagia (between 14% and 88.9%), and hearing changes (between 5.8% and 68.42%). CONCLUSION Children with congenital Zika virus syndrome may have speech, language, and hearing disorders such as hearing loss, dysphagia, alteration in the tongue frenulum, and delays in neuropsychomotor and language development.

Abstract
BACKGROUND Although it is known that Zika virus (ZIKV) infection during pregnancy may lead to microcephaly in the fetus, the prognostic factors associated with this tragic disorder remain unclear. We conducted a systematic review and meta-analysis to assess the prognostic factors associated with the incidence of microcephaly in congenital ZIKV infection. METHODS We conducted a comprehensive search in Ovid MEDLINE, Ovid MEDLINE (R) Epub ahead of print, Embase, Embase Classic, Web of Science, CINAHL, Cochrane CENTRAL, LILACS, and various thesis databases to identify human studies reporting microcephaly associated with congenital ZIKV infection. We requested primary data from the authors of the included studies to calculate summary estimates and conduct the meta-analysis of the most prevalent factors. RESULTS We screened 4106 titles and abstracts, and identified 12 studies for inclusion in the systematic review. The assessment of ZIKV infection and the definition of microcephaly varied among studies. A total of 6154 newborns/fetuses were enrolled; of those, 1120 (18.20%) had a diagnostic of ZIKV infection, of which 509 (45.45%) were diagnosed with microcephaly. Nine studies addressed the link between congenital ZIKV infection and neurological findings in newborns/fetuses. Half of the studies provided primary data. Three out of 11 factors of interest seem to be prognostic factors of microcephaly: infant's sex - males compared to females: Relative Risk (RR) 1.30, 95% Confidence Interval (95% CI) 1.14 to 1.49; the stage of pregnancy when infection occurred - infection in the first trimester of pregnancy compared to infection at other stages of pregnancy: RR 1.41, 95% CI 1.09 to 1.82; and asymptomatic infection compared to symptomatic infection during pregnancy: RR 0.68; 95% CI 0.60 to 0.77. CONCLUSION Our findings support the female-biased resistance hypothesis and reinforce the risk associated with the stage of pregnancy when ZIKV infection occurs. Continued surveillance of ZIKV infection during pregnancy is needed to identify additional factors that could contribute to developing microcephaly in affected fetuses. PROTOCOL REGISTRATION This systematic review was registered with the International Prospective Register of Systematic Reviews (PROSPERO), registration no. CRD 42018088075.

Abstract
The Zika virus (ZIKV) is a mosquito-borne Flavivirus and can be transmitted through an infected mosquito bite or through human-to-human interaction by sexual activity, blood transfusion, breastfeeding, or perinatal exposure. After the 2015-2016 outbreak in Brazil, a strong link between ZIKV infection and microcephaly emerged. ZIKV specifically targets human neural progenitor cells, suggesting that proteins encoded by ZIKV bind and inactivate host cell proteins, leading to microcephaly. Here, we present a systematic annotation of interactions between human proteins and the seven non-structural ZIKV proteins corresponding to a Brazilian isolate. The interaction network was generated by combining tandem-affinity purification followed by mass spectrometry with yeast two-hybrid screens. We identified 150 human proteins, involved in distinct biological processes, as interactors to ZIKV non-structural proteins. Our interacting network is composed of proteins that have been previously associated with microcephaly in human genetic disorders and/or animal models. Further, we show that the protein inhibitor of activated STAT1 (PIAS1) interacts with NS5 and modulates its stability. This study builds on previously published interacting networks of ZIKV and genes related to autosomal recessive primary microcephaly to generate a catalog of human cellular targets of ZIKV proteins implicated in processes related to microcephaly in humans. Collectively, these data can be used as a resource for future characterization of ZIKV infection biology and help create a basis for the discovery of drugs that may disrupt the interaction and reduce the health damage to the fetus.

Abstract
Microcephaly is a neurodevelopmental condition characterized by a small brain size associated with intellectual deficiency in most cases and is one of the most frequent clinical sign encountered in neurodevelopmental disorders. It can result from a wide range of environmental insults occurring during pregnancy or postnatally, as well as from various genetic causes and represents a highly heterogeneous condition. However, several lines of evidence highlight a compromised mode of division of the cortical precursor cells during neurogenesis, affecting neural commitment or survival as one of the common mechanisms leading to a limited production of neurons and associated with the most severe forms of congenital microcephaly. In this context, the emergence of the endoplasmic reticulum (ER) and the Golgi apparatus as key guardians of cellular homeostasis, especially through the regulation of proteostasis, has raised the hypothesis that pathological ER and/or Golgi stress could contribute significantly to cortical impairments eliciting microcephaly. In this review, we discuss recent findings implicating ER and Golgi stress responses in early brain development and provide an overview of microcephaly-associated genes involved in these pathways.

Abstract
Recently, Zika virus (ZIKV) has generated extraordinary concern because of its severe neurotoxicity. Disturbingly, there is no vaccine or specific drug to prevent or treat the diseases caused by ZIKV infection. Thus, it is extremely urgent to characterize the pathogenesis of ZIKV. It has been documented that ZIKV can evade antiviral responses of host cells. Here, we demonstrate that ZIKV strain SZ-WIV01 down-regulates the production of type I IFN and IFN-stimulated genes along with the expression of mitochondrial antiviral signaling protein (MAVS) and mediator of IFN regulatory factor 3 activation (MITA). In the mechanism, ZIKV nonstructural (NS) 3 and NS2B3 negatively regulate IFN-related retinoic acid-inducible gene I-like receptor signaling pathway by targeting MAVS and MITA, respectively. Overexpression of ZIKV NS3 and NS2B3 dramatically inhibits expression of IFN-β. ZIKV NS3 interacts with MAVS, and NS2B3 interacts with MITA, which catalyzes K48-linked polyubiquitination of MAVS and MITA for degradation. Further investigations suggest that ZIKV NS2B3 impairs polyinosinic:polycytidylic acid-triggered K63-linked polyubiquitination of MITA, thereby subverting the activation of downstream sensors. Our study reveals an undiscovered mechanism for ZIKV to escape the innate immune response, providing new insights into clinical study of vaccines or effective drugs.-Li, W., Li, N., Dai, S., Hou, G., Guo, K., Chen, X., Yi, C., Liu, W., Deng, F., Wu, Y., Cao, X.

Abstract
Since the beginning of the Zika Virus (ZIKV) epidemic, thousands of cases presenting ZIKV symptoms were recorded in Brazil, Colombia (South America), French Polynesia and other countries of Central and North America. In Brazil, during ZIKV outbreak thousands of microcephaly cases occurred that caused a state of urgency among scientists and researchers to confirm the suspected association between ZIKV infection and microcephaly. In this review article we comprehensively studied scientific literature to analyze ZIKV relationship with microcephaly, recent experimental studies, challenge and shortcomings in previously published reports to know about the current status of this association. The evidences supporting the association of ZIKV infection with congenital microcephaly and fetal brain tissue damage is rapidly increasing, and supplying recent information about pathology, clinical medicine, epidemiology, mechanism and experimental studies. However, serious attention is required toward ZIKV vaccine development, standardization of anthropometric techniques, centralization of data, and advance research to clearly understand the mechanism of ZIKV infection causing microcephaly.

Abstract
BACKGROUND Congenital microcephaly could result from a gene mutation. Asparagine synthetase deficiency, which is caused by the asparagine synthetase (ASNS) mutation, is a rare autosomal-recessive neurometabolic disorder. It is characterized by severe developmental delay, congenital microcephaly, and seizures. CASE DESCRIPTION Here we present the first report on a progressive intracerebral cyst associated with ASNS mutation, which caused neurodevelopmental dysplasia. ASNS mutation was confirmed by whole-exome sequencing and is the most likely reason for the neurodevelopmental dysplasia, which results in microcephaly, refractory seizures, and congenital visual impairment. Antiepileptic drugs have limited therapeutic effect on these epileptic seizures. CONCLUSIONS Although there is no cure for this disorder so far, the huge progressive intracerebral cyst can be cured by a cyst-peritoneal shunt.

Abstract
STUDY QUESTION What is the mechanism of sexual transmission of Zika virus (ZIKV)? SUMMARY ANSWER By utilizing exquisite reverse transcriptase-initiated in situ polymerase chain reaction (RT-in situ PCR), which enables an improved visualization of spermatozoa's subcellular compartment, we precisely localized the mid-piece of sperm that carry receptors for ZIKV. WHAT IS ALREADY KNOWN ZIKV is transmitted sexually and recent studies have verified ZIKV presence in semen of previously Zika-infected patients for >6-month postinfection when ZIKV had disappeared from blood, saliva, and urine. Strong serial analyses of various body fluids suggest that ZIKV can be transmitted between sexual partners. Currently, there is limited information on the association of the virus with human semen cell types that may carry the virus. STUDY DESIGN, SIZE, DURATION Analyses were carried out to localize ZIKV for subcellular localization of ZIKV on cell types. The Tyro3 receptor for ZIKV was colocalized by dual immunocytochemistry with specific monoclonal antibodies. PARTICIPANTS/MATERIALS, SETTING, METHODS Three semen specimens were purchased from a commercial sperm bank. Motile sperm was separated from nonmotile cells by the "swim-up" technique. Each of the semen fractions was infected with ZIKV at the multiplicity of infection of 0.1.0 and 1.0 and evaluated for the primary targets of ZIKV in the semen cells by RT-in situ PCR and confirmed by real-time RT-PCR. MAIN RESULTS AND THE ROLE OF CHANCE ZIKV was present primarily at the mid-piece of mature spermatozoa in about 30% of the sperm. In addition, we determined that Tyro3 receptors, primarily expressed on mid-piece of human spermatozoa, play a role in ZIKV-binding and entry into spermatozoa. Our data strongly suggest a potential sexual/horizontal route of transmission for ZIKV primarily via infected sperms; most likely ZIKV enters the sperm via the Tyro3 receptor found at the mid-piece of the mature spermatozoa. LIMITATIONS, REASONS FOR CAUTION We are uncertain as to what phase of spermatogenesis, that in human takes about 120 days, sperms are permissive to ZIKV. If permissiveness was very early during spermatogenesis males could be infectious for ∼120 days after the disappearance of viremia in an infected man. WIDER IMPLICATIONS OF THE FINDINGS Our findings bring a new focus on the current affords to develop ZIKV vaccine. Why in the presence of anti-ZIKV antibodies infected men are still able to transmit the virus sexually? We suggest that only certain subclass of immunoglobulin (Ig)G (ie, IgG4) can cross the blood-Sertoli barrier therefore, a successful vaccine must provoke a subclass of IgG can quell ZIKV inside the seminiferous tubules.

Abstract
Background: In this study, we use community-based participatory processes to engage community and academic partners in a meaningful exchange to identify and pilot test risk communication strategies for Zika virus prevention and control. Methods: Community members were actively involved in planning, developing, and implementing a risk communication initiative. Qualitative and quantitative data gathered through individual interviews, focus groups, and community advisory board input provided information for the identification of relevant risk communication strategies to increase the understanding about Zika virus and to promote behavior change. To examine its impact we obtained baseline and follow-up data from a random sample of 75 community residents. A face-to-face interview was conducted to assess community members' knowledge, attitudes, and behaviors regarding Zika virus infection. Results: Study activities focused on three risk communication strategies: Zika awareness health fair, health education through theater, and community forums and workshops. The risk communication initiative was implemented over a two-month period. Findings from baseline and follow-up data demonstrated significant positive changes in respondents' recognition of personal and community responsibility for the prevention of Zika infection, increased knowledge of prevention strategies, and enhanced engagement in preventive behaviors for mosquito control. Conclusion: Our findings sustain the benefits of community based participatory research for the design and implementation of risk communication strategies that are relevant to enable residents in low-income communities to take informed decisions for the protection against Zika virus and other mosquito-borne diseases.

Abstract
BACKGROUND Zika virus (ZIKV) is an emergent flavivirus, transmitted predominately by Aedes genus mosquitos that recently reached the Americas and was soon implicated in an increase in microcephaly and other serious birth defects. PURPOSE This report provides updated information and recommendations on testing, screening, and care for pregnant women and infants affected by ZIKV. METHODS Current published recommendations from the Centers for Disease Control and Prevention, the World Health Organization, and the American Academy of Pediatrics were reviewed and included in this report. RESULTS Although largely a self-limiting disease usually without symptoms, pregnant women and their fetuses are at greatest risk. Maternal transmission of ZIKV to the fetus can lead to congenital Zika infection with potentially devastating sequelae to the infant. The available evidence suggests that infection during the first trimester of pregnancy, in which the fetus' central nervous system is being formed, is associated with higher risk of brain abnormalities and perinatal loss. IMPLICATIONS FOR PRACTICE Uncertainties remain about the course of the disease, and the full spectrum of effects of the virus on the developing infant is not yet understood. Infants with congenital Zika syndrome need coordinated follow-up and long-term specialty care, as well as support for the family. IMPLICATIONS FOR RESEARCH There is no known cure for ZIKV infection and no vaccine is currently available. The full spectrum of developmental disabilities and other adverse early childhood outcomes associated with congenital ZIKV infection needs to be studied.

Abstract
The outbreak of Zika virus in Latin America in the period 2015–2016 has caused a sudden increase in the number of severe manifestations and reports of congenital changes in newborns in Brazil. This is the first study that evaluated and compared the growth and cognitive and motor development of children with microcephaly due to Congenital Zika Virus Syndrome (CZS) in relation to typical children. It was an observational, analytical, cross-sectional study with 8 children with CZS and 16 typical children, with a mean age of 20.5 months (±2.1), in a region of northeastern Brazil. Considering the mean, children with CZS presented extremely low performance in the motor domain and in the cognitive development domain, whereas typical children presented average performance in the cognitive and motor development domains. Children with CZS presented a mean growth rate (head circumference and weight) lower than typical children. Therefore, children with CZS are at risk for growth retardation and development compared to typical children.

Abstract
Zika virus infection causes serious birth defects, including microcephaly, when expectant mothers are infected during pregnancy. Zika outbreaks have been reported in the Pacific Islands, South America, the Caribbean, Africa and parts of South East Asia. Currently, there is no specific treatment available for Zika virus infection. Hence, the current study is focused to identify natural phytocompounds to control Zika virus from few endemic anti-viral herbs by in silico approach. Molecular interactions, Pharmacokinetic Study, Molecular dynamic simulation and annealing were carried out with the phytocompounds and checked using Lipinski filter. The interactions between the phytocompounds and Envelope protein (PDB id: 5JHM) of Zika virus was assessed with SYBYL-X 1.3. The results showed that tannic acid from Terminalia arjuna had better interaction, total score, CScore (6.792 and 5) and formed more number of Hydrogen bonds within 2.5 Å bond length, best activity in pharmacokinetic study, Molecular dynamic simulation and annealing temperature at 310 K. Our results suggested that tannic acid can be utilized as lead candidate to control Zika virus infection.

Abstract
OBJECTIVES The objective of this study was to understand natural disease progression in infant CD1 mice after the bite of Aedes aegypti mosquitoes infected by the Zika virus (ZIKV, MR-766 strain). METHODS A. aegypti mosquitoes were experimentally infected with ZIKV MR-766 strain via the oral feeding route. Infected mosquitoes were allowed to feed on infant CD1 mice. Sick mice were euthanized, and their organs were collected and subjected to real-time RT-PCR, histo-pathology, and immunohistochemistry. RESULTS Clinical symptoms appeared in mice after 4-5 days of being bitten by mosquitoes, following which they were euthanized. Real-time RT-PCR analysis showed the presence of viral RNA in various organs such as the brain, liver, kidney, spleen, lungs, and intestines of the mice. The brain tissue specimens showed higher viral loads as determined by threshold values (Ct value) in the real-time RT-PCR assay. Histopathological and immunohistochemistry studies also revealed the presence of the virus and associated lesions in the brain, indicating that ZIKV shows tropism for neuronal tissue. CONCLUSIONS This study demonstrates ZIKV pathogenesis in infant CD1 mice and that these mice are highly susceptible to natural infection with this ZIKV strain.

Abstract
Although infection with the Zika virus was first recognized in 1942, it received
little attention until 2007, when a true pandemic spread throughout Africa,
Asia, and the Americas. Since then, numerous forms of central nervous system
involvement have been described, mainly malformations related to congenital
infection. Although the neuroimaging findings in congenital Zika syndrome are
not pathognomonic, many are quite suggestive of the diagnosis, and radiologists
should be prepared to interpret such findings accordingly. The objective of this
article is to review the computed tomography and magnetic resonance imaging
findings in congenital Zika syndrome.

Abstract
The recent global outbreak of Zika virus (ZIKV) infection has been linked to severe neurological disorders affecting the peripheral and central nervous systems (PNS and CNS, respectively). The pathobiology underlying these diverse clinical phenotypes are the subject of intense research; however, even the principal neural cell types vulnerable to productive Zika infection remain poorly characterised. Here we used CNS and PNS myelinating cultures from wild type and Ifnar1 knockout mice to examine neuronal and glial tropism and short-term consequences of direct infection with a Brazilian variant of ZIKV. Cell cultures were infected pre- or post-myelination for various intervals, then stained with cell-type and ZIKV-specific antibodies. In bypassing systemic immunity using ex vivo culture, and the type I interferon response in Ifnar1 deficient cells, we were able to evaluate the intrinsic infectivity of neural cells. Through systematic quantification of ZIKV infected cells in myelinating cultures, we found that ZIKV infection is enhanced in the absence of the type I interferon responses and that CNS cells are considerably more susceptible to infection than PNS cells. In particular, we demonstrate that CNS axons and myelinating oligodendrocytes are especially vulnerable to injury. These results have implications for understanding the pathobiology of neurological symptoms associated with ZIKV infection. Furthermore, we provide a quantifiable ex vivo infection model that can be used for fundamental and therapeutic studies on viral neuroinvasion and its consequences.

Abstract
Zika virus is a flavivirus known to cause microcephaly during development. The mechanism underlying Zika virus-induced neuropathogenesis is still poorly understood. Recent studies have utilized the cutting edge cell culture and animal model technologies to elucidate factors contributing to Zika virus-associated microcephaly. While future work is needed, current studies have suggested three main factors that contribute to Zika virus pathology: viral lineage, host immunity, and pregnancy stages. This mini review will focus on some of the recent findings that advanced our knowledge in Zika virus-associated microcephaly.

Abstract
The presence of the Zika virus (ZIKV) infection has gone ahead to be a threat to people based on its adverse impacts. More specifically, the pregnant women have been discouraged from traveling to the areas affected by the ZIKV because of the likelihood of the virus causing congenital abnormalities especially the microcephaly. The pregnant women probably attracted the virus during their first trimester while visiting ZIKV affected territories. Although the ZIKV infected cases have reduced in some parts of countries, the global risk assessment has not been changed. The virus continues to spread geographically to areas where competent vectors are present. At present, there is still no treatment of ZIKV related illness, especially microcephaly.

Abstract
INTRODUCTION Zika virus, an arbovirus of the Flaviviridae family, is a mosquito-borne virus known to cause microcephaly through vertical transmission. Infection presents with mild, self-limiting symptoms. Currently, a Zika virus outbreak has spread across most of South and Central America. Travel-related and sexually transmitted cases have been reported across the United States. However, the vector-borne transmission has been limited to Florida and Texas. We present seven cases of Zika virus infection that presented at a single institution in South Florida. METHODS Patients were included that had real-time polymerase-chain reaction (RT-PCR) for Zika virus RNA in urine or serum or enzyme-linked immunosorbent assay (ELISA) for Immunoglobulin M (IgM) antibody against Zika virus in serum. RESULTS All seven patients reported recent travel or employment in areas of active Zika virus transmission and at least two of the four most commonly reported symptoms (fever, arthralgia, rash, and conjunctivitis) with a rash present in all patients. All patients had positive RT-PCR for Zika virus RNA in urine. RT-PCR for Zika virus RNA in serum was negative in four of five patients that were tested, indicating that these patients likely presented one to two weeks after symptom onset. CONCLUSION The future of Zika virus outbreaks in other cities in the United States is still uncertain. However, it is clear that prevention and control policies are urgently needed. We have presented seven confirmed cases of Zika virus infection in South Florida. In addition to conducting research concerning both the diagnostic and therapeutic aspects of the virus, there is a need for public awareness of its presentation, methods of transmission, and subsequent clinical outcomes.

Relative analytical sensitivity of donor nucleic acid amplification technology screening and diagnostic real-time polymerase chain reaction assays for detection of Zika virus RNA. Transfusion 2017; 57:734-747. [PMID: 28194799 DOI: 10.1111/trf.14031] [Citation(s) in RCA: 32] [Impact Index Per Article: 4.6] [Reference Citation Analysis] [Abstract] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/20/2016] [Revised: 01/02/2017] [Accepted: 01/03/2017] [Indexed: 01/28/2023]
Abstract
BACKGROUND Zika virus (ZIKV) has spread rapidly in the Pacific and throughout the Americas and is associated with severe congenital and adult neurologic outcomes. Nucleic acid amplification technology (NAT) assays were developed for diagnostic applications and for blood donor screening on high-throughput NAT systems. We distributed blinded panels to compare the analytical performance of blood screening relative to diagnostic NAT assays. STUDY DESIGN AND METHODS A 25-member, coded panel (11 half-log dilutions of a 2013 French Polynesia ZIKV isolate and 2015 Brazilian donor plasma implicated in transfusion transmission, and 3 negative controls) was sent to 11 laboratories that performed 17 assays with 2 to 12 replicates per panel member. Results were analyzed for the percentage reactivity at each dilution and by probit analysis to estimate the 50% and 95% limits of detection (LOD50 and LOD95 , respectively). RESULTS Donor-screening NAT assays that process approximately 500 µL of plasma into amplification reactions were comparable in sensitivity (LOD50 and LOD95 , 2.5 and 15-18 copies/mL) and were approximately 10-fold to 100-fold more sensitive than research laboratory-developed and diagnostic reverse transcriptase-polymerase chain reaction tests that process from 10 to 30 µL of plasma per amplification. Increasing sample input volume assayed with the Centers for Disease Control and Prevention reverse transcriptase-polymerase chain reaction assays increased the LODs by 10-fold to 30-fold. CONCLUSIONS Blood donor-screening ZIKV NAT assays demonstrate similar excellent sensitivities to assays currently used for screening for transfusion-transmitted viruses and are substantially more sensitive than most other laboratory-developed and diagnostic ZIKV reverse transcriptase-polymerase chain reaction assays. Enhancing sensitivities of laboratory-developed and diagnostic assays may be achievable by increasing sample input.

Abstract
After the first reported case of Zika virus (ZIKV) in Brazil, in 2015, a significant increase in the reported cases of microcephaly was observed. Microcephaly is a neurological condition in which the infant's head is significantly smaller with complications in brain development. Recently, two small membrane-associated interferon-inducible transmembrane proteins (IFITM1 and IFITM3) have been shown to repress members of the flaviviridae family which includes ZIKV. However, the exact mechanisms leading to the inhibition of the virus are yet unknown. Here, we assembled an interactome of IFITM1 and IFITM3 with known protein-protein interactions (PPIs) collected from publicly available databases and novel PPIs predicted using the High-confidence Protein-Protein Interaction Prediction (HiPPIP) model. We analyzed the functional and pathway associations of the interacting proteins, and found that there are several immunity pathways (toll-like receptor signaling, cd28 signaling in T-helper cells, crosstalk between dendritic cells and natural killer cells), neuronal pathways (axonal guidance signaling, neural tube closure and actin cytoskeleton signaling) and developmental pathways (neural tube closure, embryonic skeletal system development) that are associated with these interactors. Our novel PPIs associate cilia dysfunction in ependymal cells to microcephaly, and may also shed light on potential targets of ZIKV for host invasion by immunosuppression and cytoskeletal rearrangements. These results could help direct future research in elucidating the mechanisms underlying host defense to ZIKV and other flaviviruses.
