How Kaposi's sarcoma virus spreads through the mouth

Oral transmission of KSHV using rhesus macaque rhadinovirus model

NIH-funded research Oregon Health & Science University · NIH-11145772

This project looks at how the virus that causes Kaposi’s sarcoma can pass through the mouth and what makes infection more likely, using a related monkey virus and lab-grown oral cells.

What this research studies

Researchers will use a rhesus macaque model and a closely related monkey virus (RRV) that mimics human KSHV to see whether the virus can cross the oral lining to start infection. They will perform controlled infections in monkeys and map which regions of the mouth and which cell types are vulnerable. In parallel, lab-grown oral tissues and cell studies will test viral surface proteins and the receptors they bind to. The team will also use a cloned form of the monkey virus to change viral genes and see how those changes affect the ability to infect by the oral route.

Who could benefit from this research

Good fit: People living with HIV and individuals in regions where KSHV is commonly acquired early in life would be the most relevant groups for the findings of this research.

Not a fit: People without risk of KSHV exposure or whose conditions are unrelated to viral infections are unlikely to benefit directly from this project.

Why it matters

Potential benefit: If successful, this work could point to new ways to prevent KSHV spread and reduce cases of Kaposi’s sarcoma, especially in children and people living with HIV.

How similar studies have performed: Prior studies have shown the rhesus virus can reproduce KSHV-like disease after intravenous infection, but applying this model specifically to study oral transmission is relatively new.
