The Role of IL5 in Epithelial Cell Integrity
Johns Hopkins University
Summary
The goal of this laboratory study is the examine the effect of mepolizumab drug on the health and function of the cells lining the human nasal airways in vitro cell culture derived from patients with chronic rhinosinusitis with nasal polyposis. The main questions the study aims to study are: 1. To see what mepolizumab does to suppress inflammation of the human cells. 2. To see what mepolizumab does to maintain barrier integrity of epithelial cells
Description
The investigators hypothesize that anti-IL5 treatment will promote epithelial cell function by inhibition of Type 1 and innate immune mediated inflammation and epithelial-mesenchymal transition resulting from IL5 induction. Aim 1. To test the hypothesis that anti-IL5 therapy results in inhibition of epithelial cell dysfunction including epithelial derived inflammatory responses and barrier dysfunction, the investigators will examine the effect of in vitro anti-IL5 mepolizumab exposure of human primary nasal epithelial cells from chronic rhinosinusitis with nasal polyposis on Type 1, Type 2 an…
