Targeting TMEM41B, a human protein many flaviviruses and coronaviruses need

TMEM41B: a pan-flavivirus and pan-coronavirus host factor with antiviral potential

NIH-funded research Rockefeller University · NIH-11136877

Researchers are looking at whether blocking a human protein called TMEM41B can stop a range of viruses that cause illnesses like dengue and COVID-19.

What this research studies

This lab project focuses on a human cell protein, TMEM41B (and its partner VMP1), that many flaviviruses and coronaviruses hijack to remodel cell membranes and copy their RNA. Scientists use CRISPR/Cas9 gene editing to remove these proteins from human cell lines and then compare how viruses enter, translate their proteins, and build replication compartments. They combine biochemical tests, imaging, and molecular assays to pinpoint which early viral steps fail without TMEM41B or VMP1 and how the innate immune response changes. The goal is to reveal whether blocking these host factors could be a route to broad-spectrum antiviral drugs.

Who could benefit from this research

Good fit: Although this is lab-based research that does not enroll patients for treatment, people who have had or are at risk for flavivirus or coronavirus infections might be invited to donate samples for related studies.

Not a fit: Patients with non-viral diseases or anyone seeking immediate clinical treatment are unlikely to get direct benefit from this basic laboratory research.

Why it matters

Potential benefit: If successful, this work could point to new medicines that block a host protein and work against many different flaviviruses and coronaviruses.

How similar studies have performed: Prior laboratory screens have identified TMEM41B as important for these viruses, but turning that finding into safe, broad-spectrum antiviral drugs remains largely untested.
