What this research studies

If you take part, researchers at UCSF will compare samples from people with severe asthma to lab-grown airway cells to see how type 2 immune signals like IL-13 change gene activity and mucus production. They will study how secretory cells develop and how mucins are made and released, using human airway samples, cell-culture models, and molecular analyses. The Center runs two linked projects that together search for previously unrecognized molecules and pathways that lead to mucus plugging and airway obstruction.

Who could benefit from this research

Good fit: People with severe or type 2 (allergic) asthma, especially those who have mucus plugging or frequent airway obstruction, would be the best fit for participation or to benefit.

Not a fit: People with mild asthma, non-type 2 asthma, or unrelated lung diseases are unlikely to see direct benefit from this work.

Why it matters

Potential benefit: Could point to new treatments that reduce mucus plugging and improve breathing in people with severe, type 2 asthma.

How similar studies have performed: Prior research has shown IL-13 and type 2 inflammation drive mucus changes and that targeting type 2 pathways helps some patients, but the specific molecular mechanisms targeted here are largely novel.
