Asthma and respiratory allergies: a promising new therapeutic target

Asthma and respiratory allergies: a promising new therapeutic target

French teams (CNRS, Inserm, University of Toulouse III — Journal of Experimental Medicine) have identified TL1A, an alarmin released together with IL-33 within the first minutes of allergen contact. By acting upstream of the inflammatory cascade, blocking TL1A could help patients with severe asthma. Anti-TL1A antibodies already exist (Crohn's disease), which could speed up their evaluation. A very promising avenue, to be confirmed by clinical trials.

Studied in frogs (up to 250 receptors versus ~25 in humans), they could take part in food detection and immune activation. A promising fundamental-research advance, but without immediate clinical application.
