Scientists have uncovered a crucial mechanism in the replication of the Ebola virus. This could potentially lead to new treatment doors.
Ebola Virus
Ebola virus disease (EVD) is a deadly and rare disease that can affect humans and other primates. Infection can take place by getting into contact with infected animals during preparing, cooking, or eating them, body fluids of a person who is infected, and things contaminated with an infected person's body fluids.
The virus may enter the body through skin cuts or when it gets into contact with the mouth, nose, or eyes of a person. Early symptoms of ebola include headaches, fever, and fatigue.
The pathogen has been responsible for grave outbreaks and mortality rates across sub-Saharan Africa. Its discovery dates back to 1979, when two outbreaks took place across different areas of Central Africa. For a long time, it has been considered a concerning threat to global public health.

Key Mechanism in Ebola Virus Replication
Now, researchers have reached a breakthrough in understanding how the virus can replicate within the cells of humans. The study shows that antiviral drug treatments could focus on a new target. This may lead to more effective therapies for the deadly condition. Findings were documented in the "Ebola virus VP35 interacts non-covalently with ubiquitin chains to promote viral replication" study.
As part of the study, the scientists focused on the interaction between the Ebola virus VP35 protein and ubiquitin, which can be found in the cells of humans. This interaction is crucial to the ability of the virus to replicate and avoid the immune system.
Rafael Najmanovich, a co-author of the study and a pharmacology professor at Université de Montréal, says that they were able to predict the area where the Ebola virus protein binds to the chains of ubiquitin. They were even able to identify possible drug candidates that could disrupt the interaction. Najmanovick explains that the discovery does not just deepen virus understanding but also offers a potential avenue for more effective therapies to be created. It particularly paves the way for drug design that can disrupt interactions and slow down the replication of the virus.
With the assistance of advanced techniques in cell biology, molecular biology, biophysics, and computational modeling, the researchers were able to look into complex viral replication molecular processes.
One of the crucial findings of the study was the identification of a previously unknown interaction of VP35. The novel insight helps shed light on the complex interplay between the immune system of the host and the virus. Through the interaction, the virus can avoid being detected and subvert the defense of the host.
Najmanovich explains that the study shows the grave importance of examining the intricate mechanisms that viruses like Ebola use. This could ultimately result in the novel development of treatments to combat them. He adds that their study serves as an important step forward in the battle against infectious diseases.
