Potent Restriction of Sexual Zika Virus Infection by the Lipid Fraction of Extracellular Vesicles in Semen

Drs. Lucia Vojtech, Germán Gornalusse, and Florian Hladik authored "Potent Restriction of Sexual Zika Virus Infection by the Lipid Fraction of Extracellular Vesicles in Semen", published in Frontiers in Microbiology. To learn more, follow the link below.

Mission: Our mission is to reduce the burden of infections that may harm individuals and families. We strive to gain a deep understanding of the immune defenses in the female reproductive tract and the placenta to better prevent and treat infections during all stages of the life cycle. We envision a world free of preventable infections, or where people who already carry viruses such as herpes simplex and human immunodeficiency virus can be cured.


Notable achievements

  • Characterization of messenger nucleic acids carried by extracellular vesicles in semen. 
  • Elucidation of the earliest steps how human immunodeficiency virus penetrates the female genital mucosa and establishes infection. Exact knowledge about how someone is infected with HIV helps in devising strategies to prevent infection.
  • Development of a new genetic assay to measure the latent HIV reservoir, which will be an essential tool for clinical trials that aim to cure HIV infection.
  • First to demonstrate that a maternal Zika virus infection could cause fetal brain injury in a nonhuman primate model.
  • First to show that a choriodecidual Group B Streptococci infection could induce fetal lung injury prior to labor, mediated by cytokine production of placenta in the course of resolving the infection.
