New Discovery Could Change How Asthma Is Treated, Scientists Say

WEDNESDAY, Jan. 28, 2026 (HealthDay News) — Scientists may have uncovered a new cause of asthma that could change how the disease is treated.

Researchers at Case Western Reserve University in Cleveland, Ohio, say they’ve identified previously unknown molecules that may play a major role in asthma-related inflammation.

The findings suggest these chemicals, called “pseudo leukotrienes,” could be more important than the leukotrienes doctors have focused on for decades.
