Resumo

Introdução: A maioria das pesquisas médicas necessita de modelos animais para ampliar o conhecimento sobre as causas e consequências das doenças humanas, possibilitando com isso novos testes e terapias inovadoras. Apesar dos roedores serem frequentemente utilizados, o Zebrafish é um vertebrado que foi introduzido com êxito no cenário científico, constituindo um excelente modelo experimental para estudo de diversas doenças e testar novos agentes terapêuticos. Objetivo: O objetivo do estudo foi mostrar a importância do Zebrafish como modelo animal no cenário científico. Material e métodos: Trata-se de um estudo exploratório, realizado por meio de uma pesquisa bibliográfica. Realizou-se buscas nas bases PubMed e Web of Science. Foram selecionados 8 artigos que atenderam aos critérios de inclusão. Resultados: O Zebrafish é um pequeno teleósteo tropical de água doce introduzido na ciência na década de 80 pelo biólogo George Streisinger da University of Oregon (USA). Seus estudos revolucionários permitiram que os cientistas realizassem experimentos no Zebrafish, antes possíveis apenas em invertebrados. O Zebrafish tem substituído os roedores na pesquisa, pois apresenta baixo custo de reprodução, fertilização externa, geneticamente manipulável e com genoma sequenciado com homologia com os mamíferos. Além disso, seu desenvolvimento ocorre até 72 horas após fertilização e com embrião transparente durante todo seu desenvolvimento, permitindo acompanhar as mutações, em tempo real ao ser manipulado por estratégias farmacológicas ou de bloqueio gênico. Em estudos comportamentais, o Zebrafish se destaca na análise da resposta de medo e condições psicopatológicas como a ansiedade, devido a sua conservação genética e comportamentos característicos, sendo um modelo bem estabelecido em pesquisas neurocomportamentais. Conclusão: É notória a importância do uso do Zebrafish como organismo experimental de pesquisas científicas, sendo utilizado em inúmeras áreas como neurofisiologia, genéticas e toxicologia, além de aplicações na indústria farmacêutica, acelerando o processo de testes de novas drogas.
