Abstract
Allergic rhinitis（AR） is a non-infectious chronic inflammatory disease of the nasal mucosa mainly mediated by immunoglobulin E（IgE） in atopic individuals after exposure to allergens. T cells are the core cell population. In recent years, studies have shown that memory T cells play an important role in the development of allergic rhinitis. This article reviews the pathogenesis of memory T cells in allergic rhinitis, in order to further improve the pathogenesis of allergic rhinitis and provide theoretical basis and reference for subsequent clinical drug treatment.
