Resumo: Malaria caused by Plasmodium falciparum represents one of the leading causes of child mortality in tropical and subtropical regions. Because no vaccine is available, treatment-based case management is the primary option for malaria control. However, over time, P. falciparum parasites have evolved resistance to all available drugs. Our group has developed a novel paradigm that brings together principles of classical genetics and innovative concepts of genomics, in order to understand the genetic and molecular basis of resistance to antimalarials. This strategy makes use of an isogenic lineage of the rodent parasite Plasmodium chabaudi, consisting of various clones that are either sensitive or resistant to different drugs, whose genomes are scrutinized in search for mutations responsible drug resistance. Using this strategy, the genetic basis of resistance to various antimalarials, such as pyrimethamine, chloroquine, mefloquine and artemisinin, has been clarified.

Dado não existir vacina disponível, o tratamento de casos é a principal opção para o controle da malária. No entanto, no decorrer do tempo, o parasita P. falciparum adquiriu resistência a todos os fármacos disponíveis. O nosso grupo desenvolveu um novo paradigma que congrega princípios de genética clássica e conceitos inovadores de genómica, no intuito de compreender as bases genéticas e moleculares da resistência a antimaláricos. Esta estratégia faz uso de uma linhagem isogénica do parasita de roedores Plasmodium chabaudi, constituída por clones sensíveis ou resistentes a diversos fármacos, cujos genomas são escrutinados na procura de mutações responsáveis pela farmacoresistência. Usando esta estratégia, foram clarificadas as bases genéticas da resistência a vários antimaláricos, tais como pirimetamina, cloroquina, mefloquina e artemisinina.Universidade Nova de Lisboa2018-04-27T00:00:00Zinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articleapplication/pdfhttps://doi.org/10.25761/anaisihmt.30oai:ojs.anaisihmt.com:article/30Anais do Instituto de Higiene e Medicina Tropical; Vol 16 (2017):  4.º Congresso Nacional de Medicina Tropical; 65-68Anais do Instituto de Higiene e Medicina Tropical; v. 16 (2017):  4.º Congresso Nacional de Medicina Tropical; 65-682184-23100303-7762reponame:Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos)instname:Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãoinstacron:RCAAPporhttp://anaisihmt.com/index.php/ihmt/article/view/30https://doi.org/10.25761/anaisihmt.30http://anaisihmt.com/index.php/ihmt/article/view/30/24Cravo, Pedroinfo:eu-repo/semantics/openAccess2022-09-23T15:30:15Zoai:ojs.anaisihmt.com:article/30Portal AgregadorONGhttps://www.rcaap.pt/oai/openaireopendoar:71602024-03-19T16:03:50.540511Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos) - Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãofalse
