Researchers at the UC San Diego Jacobs School of Engineering developed an experimental treatment that combats this spread.
To treat Ebola virus infections, researchers are taking a close look at a key piece of the virus: polymerase. Polymerase is a viral protein that directs how Ebola virus replicates its genome as it infects new hosts. Drugs that target polymerase could potentially treat Ebola virus infections and save lives.

Each T cell expresses a TCR specific for an HLA‑presented peptide signal, and when that signal is detected a T cell expressing the relevant TCR can launch a complex array of immune effector responses that can suppress or destroy tumours or virus-infected cells.
When COVID-19 emerged in 2019, by contrast, mRNA vaccines developed by Pfizer and Moderna took just 326 days from the initial sequencing of the virus to gaining approval for emergency use. These drugs would be ideal tools to bridge the wait for a vaccine against a quickly-spreading virus.
