Resumo
Arboviruses are worldwide distributed arthropod-borne viruses representing a constant threat to public health. Among these arboviruses, the Chikungunya (CHIKV) and Zika (ZIKV) viruses have a high prevalence in Brazil being responsible for recent outbreaks resulting mainly in irreparable socioeconomic damages such as the high rate of cases of comorbidities and microcephaly in newborns, respectively. Therefore, it is necessary to understand the biology of these arboviruses and develop effective treatments against them; moreover, appropriate mice animal models are strongly encouraged. Here we reviewed the scientific literature aiming to improve the search for the best murine animal model, specific for the arboviruses, specifically, CHIKV and ZIKV. In this way, we performed a comparison between the various mice models currently available, among them: genetically modified immunosuppressed animals, as the A129 and AG129 which are knockout animals for the α/ß and α/ß/γ receptors, respectively, neonatal immunocompetent models C57BL/6 strains used between 6-8 days old for neuropathogenesis studies or 1 day old for vaccine safety studies and finally immunosuppressed induced by dexamethasone or interferon 1 blocker for pathogenesis studies. Mice models are the first option after in vitro analysis, as they are small animals, which facilitates handling and maintenance, in addition to being more inexpensive and abundantly available in different genetic strains, both wild and modified. If the results of this stage are promising, the studies move forward to the use of models with animals of greater complexity, such as rats, non-human primates and finally humans. For this review, we searched through articles in PubMed, Scopus and ScienceDirect databases using the criteria of date publications, titles, abstracts and complete manuscripts. The correct choice of these models during experimental planning is essential, since increases the confidence and the rational use of animals in experimentation in accordance to current bioethics guidelines.
