Calcitonin Gene-Related Peptide For The Reduction Of Allergen-Induced Airway Hyperresponsiveness

Tech ID: 00-14

Calcitonin gene-related peptide (CGRP) is a sensory neuropeptide which expression is reduced after allergen challenge in sensitized mice. The same mice develop eosinophilic airway inflammation and airway hyperresponsiveness (AHR). Scientists at National Jewish Health have shown that administration of CGRP to sensitized and challenged mice resulted in the normalization of AHR.


Potential Application
Treatment of AHR


State of Development
Administration of CGRP to sensitized and challenged mice resulted in the normalization of AHR.

This potential therapy for AHR was tested in phase II of clinical trials however the trial was never completed.
