UFG descobre novos possíveis compostos contra o vírus Zika
Em maio de 2016, a Universidade Federal de Goiás (UFG), em parceria com a World Community Grid (WCG), da International Business Machines (IBM), iniciou o projeto OpenZika, que visa identificar substâncias com potencial para tratar pessoas infectadas pelo vírus Zika. De uma lista inicial de aproximadamente 7.600 compostos, dentre eles fármacos já aprovados para uso […]
Crystal structure of Zika virus NS5 RNA-dependent RNA polymerase
The current Zika virus (ZIKV) outbreak became a global health threat of complex epidemiology and devastating neurological impacts, therefore requiring urgent efforts towards the development of novel efficacious and safe antiviral drugs. Due to its central role in RNA viral replication, the non-structural protein 5 (NS5) RNA-dependent RNA-polymerase (RdRp) is a prime target for drug […]
Molecular dynamics simulations of Zika virus NS3 helicase: Insights into RNA binding site activity
America is still suffering with the outbreak of Zika virus (ZIKV) infection. Congenital ZIKV syndrome has already caused a public health emergency of international concern. However, there are still no vaccines to prevent or drugs to treat the infection caused by ZIKV. The ZIKV NS3 helicase (NS3h) protein is a promising target for drug discovery […]
The spectrum of neuropathological changes associated with congenital Zika virus infection
A major concern associated with ZIKV infection is the increased incidence of microcephaly with frequent calcifications in infants born from infected mothers. To date, postmortem analysis of the central nervous system (CNS) in congenital infection is limited to individual reports or small series. We report a comprehensive neuropathological study in ten newborn babies infected with […]
Zika Virus Infection and Solid Organ Transplantation: A New Challenge
Public health concerns exist surrounding the epidemic of the Zika virus (ZIKV) and the rapid growth of transplantation in developing countries, including endemic zones of active arbovirus transmission, as well as travel to such regions by potential organ donors and recipients. Few data exist regarding the clinical characteristics of ZIKV infection in immunocompromised hosts. Laboratory […]
Zika virus causes testicular atrophy
Zika virus (ZIKV) is an emerging mosquito-borne flavivirus that has recently been found to cause fetal infection and neonatal abnormalities, including microcephaly and neurological dysfunction. ZIKV persists in the semen months after the acute viremic phase in humans. To further understand the consequences of ZIKV persistence in males, we infected Ifnar1−/− mice via subcutaneous injection […]
Genome sequencing reveals Zika virus diversity and spread in the Americas
Despite great attention given to the recent Zika virus (ZIKV) epidemic in the Americas, much remains unknown about its epidemiology and evolution, in part due to a lack of genomic data. We applied multiple sequencing approaches to generate 100 ZIKV genomes from clinical and mosquito samples from 10 countries and territories, greatly expanding the observed […]
Structural basis of Zika virus methyltransferase inhibition by sinefungin
New high resolution structure of ZIKV NS5 methyltransferase with the inhibitor sinefugin is available in Protein Data Bank (PDB ID: 5MRK). See more
