How a human protein can block the entry of the COVID-19 virus

Entry inhibition of SARS-CoV-2 by human LRRC15

NIH-funded research Brown University · NIH-10886525

This study is looking at a protein in our bodies called LRRC15 to see if it can help stop the COVID-19 virus from getting into our cells, which could lead to new ways to protect people from the virus.

What this research studies

This research investigates how a human protein called LRRC15 can inhibit the entry of the SARS-CoV-2 virus, which causes COVID-19. The study focuses on the interaction between LRRC15 and the spike protein of the virus, specifically how it binds to the receptor ACE2, which is crucial for the virus to enter human cells. By understanding this interaction, researchers aim to identify new therapeutic strategies that could prevent the virus from infecting cells. The approach includes binding assays and cellular models to evaluate the effectiveness of LRRC15 in blocking viral entry.

Who could benefit from this research

Good fit: Ideal candidates for this research are individuals at risk of COVID-19 infection, including those with underlying health conditions or those exposed to the virus.

Not a fit: Patients who have already been infected with COVID-19 and are seeking treatment for existing symptoms may not benefit from this research.

Why it matters

Potential benefit: If successful, this research could lead to new treatments that prevent COVID-19 infection by blocking the virus's ability to enter human cells.

How similar studies have performed: While the approach of targeting viral entry is established, the specific role of LRRC15 in inhibiting SARS-CoV-2 is novel and has not been extensively tested in prior research.
