IRE1 Alpha and COVID-19: how a cell-stress protein affects infection

Role of IRE1 Alpha in Coronavirus Infections

NIH-funded research University of Washington · NIH-11285331

This project will test whether blocking a cell-stress protein called IRE1 Alpha can reduce SARS-CoV-2 replication and harmful inflammation in people with COVID-19.

What this research studies

Researchers will study how IRE1 Alpha helps the coronavirus replicate using infected human cells in the lab. They will also analyze blood and tissue samples from people who had COVID-19 to see whether IRE1 Alpha activity links to worse illness, especially in older adults or people with diabetes, obesity, or high blood pressure. The team will test drugs that block IRE1 Alpha (some already being studied for other diseases) to see if they can lower virus levels or inflammatory signals in these models. These lab and specimen studies aim to build preclinical evidence that could support future treatment trials.

Who could benefit from this research

Good fit: Ideal participants would be people with confirmed COVID-19, especially older adults or those with conditions linked to ER stress such as obesity, diabetes, or high blood pressure who can provide clinical samples.

Not a fit: People without active COVID-19 or those with mild, self-limited illness may be unlikely to benefit directly because this research is preclinical and focuses on lab and sample analysis.

Why it matters

Potential benefit: If successful, this work could point to new treatments that reduce virus levels and dangerous inflammation in COVID-19 using IRE1 Alpha blockers.

How similar studies have performed: Previous lab studies link IRE1 Alpha to inflammation and some drugs targeting it are in development for non-infectious diseases, but applying these inhibitors to SARS-CoV-2 is a relatively new idea.
