Abstract

The Zika virus (ZIKV) emerges as a global health problem and demands efforts of the scientific community to understand the underlying mechanisms involved in the host cell infection. The ZIKV is part of the flavivirus genus, such as Dengue virus, whose cellular invasion mechanism has been elucidated in the literature. It is clear the involvement of Axl receptor Tyro3 and Mer (Family TAM) and its ligands, Gas6 and Protein S, during infection of Dengue virus, a phosphatidylserine-dependent phagocytosis mechanism. Studies conducted by our group showed a possible link between increased expression of TAM receptors and the infection of ZIKV, as well as the susceptibility of SJL mouse strain to ZIKV infection. However, further studies are needed to prove the role of TAM receptors in ZIKV infection and its relationship with susceptibility and resistance of SJL and C57BL/6 strains, respectively. Thus, this study aims to assess the relevance of TAM receptors in ZIKV infection in different individuals through comparisons between mouse strains, and perhaps unravel the basis of the pathogenesis of microcephaly caused by ZIKV in SJL mice. For this purpose, will perform in vitro assays of macrophages and dendritic cells infection derived from SJL mice and C57BL/6 mice, and will use the qPCR analysis, flow cytometry and western blotting techniques to evaluate the expression levels, to measure viral potential to bind and internalize in the target cells and the activation of TAM receptors.
