Abstract: Objective To investigate the expression of interleukin-4 (IL-4), IL-17, IL-6 and immunoglobulin antibodies in early stage of allergic rhinitis (AR) response and their association with allergic symptoms.Methods At early stage (day 16) and late stage (day 30) of ovalbumin (OVA)-induced allergic rhinitis (AR) mouse model, nasal symptoms were measured; nasal mucosa was collected to detect the gene expression of interferon-γ(IFN-γ), IL-4, IL-17 and IL-6; serum was collected to detect the levels of OVA-specific IgE, IgG1, IgG2a and protein expression of IFN-γ, IL-4, IL-17 and IL-6.Results The number of nasal rubbings and sneezes was increased significantly in late stage compared to early stage and control, and had no significant difference between early stage and control. The level of serum OVA-specific IgE was significantly higher in early stage and late stage than that in control, but has no significant difference between early stage and late stage. Serum OVA-specific IgG1and IgG2a, gene expression of IL-17 and IL-6 in nasal mucosa, and serum IL-17 and IL-6 protein had similar expression patterns. These variables were significantly higher in early stage and late stage than those in control, and significantly higher in late stage than those in early stage. Gene expression of IL-4 in nasal mucosa and serum IL-4 protein levels in late stage was significantly higher than those in control.Conclusion IL-17, IL-6, and allergen specific IgG1 and IgG2a may be involved in the early stage of host against allergen response, and their levels may be associated with allergic symptoms.
