Abstract:
Objective To investigate the effects and mechanisms of anti-IL-13 monoclonal antibody in alle-viating goblet cell metaplasia and hyperplasia in the treatment of acute subglottic laryngitis.Methods Periph-eral blood samples of children with acute subglottic laryngitis were collected and the children were divided into Mild group and Moderate-Severe group.Normal bronchial epithelial cells(NHBE cells)were cultured in vitro at the gas/liquid interface(ALI).Cell experiment were grouped as follows:Group-1(NHBE cell maintenance cultured group),Group-2(ciliated cell differentiation induction group),Group-3(IL-13 treatment group),and Group-4(IL-13+anti-IL-13 monoclonal antibody treatment group).The levels of inflammatory cytokines IL-10,IFN-γ and IL-13 in peripheral blood or cell culture supernatant were measured by enzyme linked immu-nosorbent assay(ELISA).The expression levels of goblet cell differentiation marker WGA and ciliary cell dif-ferentiation marker AAT,and the levels of phosphorylated(p-)ERK 1/2 and ERK 1/2 were determined by Western blot.The Cells diameter were measured by optical microscope.In vivo experiment,30 female C57BL/6J mice were randomly divided into Control group,Model group[(ovalbumin(OVA)and lipopolysaccharide(LPS)induced ashma mice model],and Model+anti-IL-13 antibody group(mice were treated intranasal with anti-IL-13 monoclonal antibody),10 mice in each group.Results Compared with Mild group,serum levels of IL-10,IFN-γ and IL-13 in Moderate-Severe group were increased(P<0.05).Compared with Group-1 cells,in Group-2 cells AAT expression was up-regulated(P<0.05).Compared with Group-1 cells,in Group-3 cells WGA expression was up-regulated(P<0.05),the levels of IL-10,IFN-γ,and IL-13 were increased(P<0.05),goblet cells diameters increased(P<0.05),and the levels of p-ERK 1/2 were up-regulated(P<0.05).Compared with Group-3,in Group-4 cells WGA expression were down-regulated(P<0.05).IL-10,IFN-γ,and IL-13 levels were decreased(P<0.05),goblet cells diameters decreased(P<0.05),and the levels of p-ERK 1/2 were down-regulated(P<0.05).There was no significant difference in the expression levels of ERK 1/2 among the four groups(P>0.05).In vivo animal experiment,compared with Control group,the bronchial inflammation score of the Model group mice was increased(P<0.05).Compared with Model group,the bronchial inflammation score of the Model+anti-IL-13 antibody group was decreased(P<0.05).Conclusion Anti-IL-13 monoclonal antibody can inhibit airway goblet cell metaplasia and hyperplasia,and may be used to relieve acute subglottic laryngitis.
