Blocking a protein to prevent SARS-CoV-2 infection

Blocking TMPRSS2 expression for prevention of SARS-CoV-2 infection

['FUNDING_R21'] · UNIVERSITY OF GEORGIA · NIH-10449301

This study is looking at whether blocking a certain protein called TMPRSS2 can help stop the SARS-CoV-2 virus from getting into our cells, and it's for anyone interested in new ways to fight COVID-19.

What this research studies

This research investigates how blocking the expression of a specific protein, TMPRSS2, can prevent the SARS-CoV-2 virus from entering human cells. The approach involves using inhibitors that target androgen receptor signaling, which is known to regulate TMPRSS2 levels. By reducing TMPRSS2 in respiratory epithelial cells, the research aims to stop the virus from activating and infecting these cells. The study will involve both genetic and pharmacological methods to assess the effectiveness of these inhibitors in a laboratory setting.

Who could benefit from this research

Good fit: Ideal candidates for this research are individuals at high risk for SARS-CoV-2 infection, particularly those with underlying health conditions that affect respiratory function.

Not a fit: Patients who are not at risk for SARS-CoV-2 infection or those who have already been vaccinated may not receive direct benefits from this research.

Why it matters

Potential benefit: If successful, this research could lead to new preventive strategies against SARS-CoV-2 infection, potentially reducing the spread of COVID-19.

How similar studies have performed: Other research has shown promise in targeting TMPRSS2 and androgen receptor signaling as a viable approach to inhibit viral infections, suggesting potential success for this study.
