How does Tezspire (tezepelumab) work in the body?
Tezspire (tezepelumab) is a monoclonal antibody designed to block thymic stromal lymphopoietin (TSLP), an immune signaling protein involved in airway inflammation. By binding TSLP, tezepelumab prevents TSLP from activating inflammatory pathways that contribute to asthma symptoms and exacerbations [1].
What pathway does blocking TSLP affect in asthma?
TSLP acts upstream in the inflammatory cascade in asthma. When TSLP signaling is blocked, downstream immune activation linked to airway inflammation is reduced, which helps decrease disease activity and lower the risk of asthma flare-ups [1].
Does Tezspire target TSLP specifically, or does it affect multiple cytokines?
Tezspire’s mechanism of action is centered on TSLP neutralization. Rather than directly blocking a single downstream cytokine, the treatment works upstream by interrupting TSLP-driven signaling that can influence multiple inflammatory processes relevant to asthma [1].
Why is TSLP considered an important target for asthma?
TSLP is associated with triggering and amplifying airway inflammation. Because it sits early in the inflammatory signaling chain, inhibiting TSLP can help control asthma across different inflammatory patterns rather than only blocking one downstream mediator [1].
