Recently, Zika virus (ZIKV) causes millions of infections which emerge as a new dangerous member of the genus of Flavivirus. Unlike other well-known flaviviruses, ZIKV can be transmitted sexually and infect testes in murine models. However, the exact susceptible cells are not entirely clear. To investigate these issues, we infected interferon �?±/�?² and �?³ receptors deficient AG6 mice with ZIKV and examined the outcomes of infection. Infected mice displayed signs of reproductive system disorder, altered androgen levels in serum, and high viral load in semen and testes. Seminiferous tubules showed atrophy, accompanied by positive staining of ZIKV antigens on Sertoli cells. Viral particles and vacuole changes were observed within Sertoli cells, whose susceptibility to ZIKV was further validated in vitro study using cell lines. The disruption of tight junctions within testis and altered sperm morphology were also observed in ZIKV infected mice. Our results therefore demonstrated that Sertoli cells are susceptible to ZIKV infection, which results in the disruption of tight junctions in testis and causes abnormal spermatogenesis in mice. These results also imply that long-term impact of ZIKV infection on human male reproductive system requires close monitoring..

Jing An graduated from Chinese Medical University in 1982 in Shenyang of China. She got her Master’s degree and PhD in Clinical Medicine in 1989 at the Third Military Medical University in Chongqing (China), followed by a Postdoctoral position and Research Fellow position at the Department of Microbiology and Immunology in Tokyo (Japan) at the Metropolitan Institute for Neuroscience. In autumn 2000, she returned to China and occupies since the position of a Principal Investigator and Head of the Department of Microbiology at the Capital Medical University of Beijing (China). Her research focuses on the interaction between mosquito-borne flaviviruses and host as well as prevention of dengue virus infection.
