Mucus samples were collected from this introductory cohort of 10 patients diagnosed with chronic rhinosinusitis with nasal polyps at Tufts Medical Center (Boston, Massachusetts). Relative levels of SP and HK\u20101 were measured with enzyme\u2010linked immunosorbent assay methods. Both inflammatory neuropeptides were found in detectable and comparable amounts in patient samples and in concentrations up to 100\u2010fold those established in past literature. The presence of SP and HK\u20101\u00a0necessitates further investigation into their role in nasal polyposis and the potentiation of the chronic inflammation inherent to chronic rhinosinusitis. Downregulating these peptides could therefore provide novel treatment targets to manage this disease process.<\/jats:p>","DOI":"10.1177\/2473974x19875076","type":"journal-article","created":{"date-parts":[[2019,9,12]],"date-time":"2019-09-12T13:11:55Z","timestamp":1568293915000},"update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":5,"title":["Substance
