Cortactin expression in nasal polyps of aspirin-exacerbated respiratory disease (aerd) patients

The term aspirin-exacerbated respiratory disease (AERD) refers to a combination of asthma, chronic rhinosinusitis with nasal polyposis (CRSwNP), and acute respiratory tract reactions to nonsteroidal anti-inflammatory drugs. AERD has now been included among the CRSwNP endotypes, and is considered one of the most aggressive in terms of disease recurrence.Cortactin is a multi-domain protein with a part in several cellular mechanisms involving actin assembly and cytoskeleton arrangement. Cortactin seems to have a role in inflammatory responses and to be implicated in human airway secretion and contraction mechanisms.
