\n

No UFPA Pesquisa dessa semana, falamos sobre um assunto fundamental para a sa\u00fade p\u00fablica do Brasil na atualidade, a epidemia do v\u00edrus zika, que tanto tem preocupado popula\u00e7\u00e3o e autoridades, principalmente pela associa\u00e7\u00e3o com o nascimento de beb\u00eas com microcefalia.<\/h4>\n<\/header>\n
\n

Para conversar sobre o tema, recebemos Pedro Vasconcelos, doutor em Medicina e Sa\u00fade e diretor do Instituto Evandro Chagas, centro de pesquisa refer\u00eancia nos estudos sobre zika, e Walace Leal, doutor em Ci\u00eancias Biol\u00f3gicas e coordenador do Laborat\u00f3rio de Neuroprotec\u00e3o e Neurorregenerac\u00e3o Experimental da UFPA.<\/h4>\n

Durante o programa, o doutor Pedro Vasconcelos fala sobre as formas de transmiss\u00e3o do v\u00edrus e propostas para combate ao vetor, o Aedes aegypti, como estudos com mosquitos transg\u00eanicos. De acordo com ele, a estrat\u00e9gia de impedir a reprodu\u00e7\u00e3o do inseto em \u00e1gua parada ainda \u00e9 a \u00fanica alternativa vi\u00e1vel no pa\u00eds, a curto prazo.<\/h4>\n

O m\u00e9dico comenta tamb\u00e9m a principal descoberta epidemiol\u00f3gica de sua equipe sobre o zika, de que foi introduzido no pa\u00eds em 2013, durante a Copa das Confedera\u00e7\u00f5es, e o desenvolvimento de uma vacina, projeto realizado pelo Instituto Evandro Chagas, em parceria com uma universidade do Texas, nos Estados Unidos. Dois tipos de vacinas devem ser produzidas: uma com o v\u00edrus atenuado e outra pela t\u00e9cnica de gen\u00e9tica reversa, para mulheres gestantes, que n\u00e3o poder\u00e3o receber a vacina com atenua\u00e7\u00e3o.<\/h4>\n

Tamb\u00e9m nessa edi\u00e7\u00e3o do UFPA Pesquisa, o professor e neurocientista Walace Leal explica que pesquisas demonstram que o nexo causal entre o zika e les\u00f5es do sistema nervoso, como a microcefalia, j\u00e1 est\u00e1 bem estabelecido. Ele cita como exemplos dois tipos de estudos, in vitro e in vivo. No primeiro caso, j\u00e1 foi observado que o v\u00edrus induz a morte das c\u00e9lulas progenitoras neurais e altera sua capacidade de reprodu\u00e7\u00e3o. J\u00e1 nos estudos in vivo com camundongos, a diminui\u00e7\u00e3o do tamanho do enc\u00e9falo dos roedores e outras altera\u00e7\u00f5es do sistema nervoso s\u00e3o diretamente associadas \u00e0 contamina\u00e7\u00e3o pelo zika.<\/h4>\n<\/section>\n","protected":false},"excerpt":{"rendered":"
