The Ebola virus, one of the deadliest pathogens, poses a serious threat to global health and safety, with a fatality rate of about 50%. Current antibody-based treatments have led to progress but there is still a need to address the limitations that exist in reducing mortality rates and managing viral survival in patients while creating affordable and accessible treatment options. Researchers from the University of Minnesota and the Midwest Antiviral Drug Discovery (AViDD) Center developed initial nanobody-based inhibitors against the Ebola virus which provide promising tools for combating this dangerous disease.

Discovery Highlight

Researchers developed the pioneering discovery of two novel nanobody inhibitors called Nanosota-EB1 and Nanosota-EB2 aimed at blocking Ebola virus glycoprotein (GP). Nanobodies derived from camelid animals including alpacas maintain their unique advantages over standard antibodies because they consist of single-domain segments. Because of their minute size, nanobodies penetrate virus locations and human tissue regions that standard antibodies cannot reach leading to increased effectiveness against viral infections.

Nanosota-EB1 and Nanosota-EB2 have distinct inhibitory methods that fight Ebola virus infections by different mechanisms. The glycan cap region of the GP1 subunit binds to Nanosota-EB1 thus blocking protease cleavage of the virus which prevents human cell attachment. Nanosota-EB2 targets pre-fusion critical membrane-fusion elements on the GP2 subunit to maintain its stable pre-fusion state which prevents the entry of the Ebola virus into host cells. Cryogenic electron microscopy and biochemical studies revealed both the high accuracy and effectiveness of these nanobodies through structural evidence.

In Vitro and In Vivo Results

Research data shows that these nanobodies have strong capacities to deactivate the Ebola virus during controlled laboratory experiments. Two nanobody candidates exhibited strong in vitro neutralization ability with Nanosota-EB2 showing effective protection against Ebola virus infection in mouse models. Studies conducted in living animals demonstrated that treatment with Nanosota-EB2 increased survival while simultaneously lowering Ebola viral amounts within Ebola-infected mice, thus demonstrating promising prospects as a therapeutic candidate.

Expanding the Fight Beyond Ebola

Nanosota-EB1 and Nanosota-EB2 represent important achievements in Ebola virus therapy, and provide a fundamental basis for nanobody-based treatments against other filoviruses including the Sudan virus and the Marburg virus. These nanobodies demonstrate high adaptability while being cost-efficient, easy to produce and stable, making them promising antiviral candidates for multiple virus applications.
