Research Topic

Exploring the effects of mitochondrial genetic variation on tumor antigen rejection and SARS-CoV-2 pathogenicity in mice

Arnold Olali

Children's Hospital of Philadelphia (CHOP)


I am excited about understanding how mitochondria affect overall health. The mitochondria are maternally inherited and highly variable, which allows for easy adaptation to adverse environments and energy demands. However, these variants can predispose us to common diseases, including cancer, and increase symptom severity following viral infection. The current project I am working on is focused on understanding how mitochondrial DNA variation drives the risk of developing cancer, or worsening symptoms following COVID-19 infection.
