Programmed cell death in the epithelial cells of the nasal mucosa in
allergic rhinitis
Abstract
Abstract In allergic rhinitis (AR), the epithelial barrier
composed of nasal mucosal epithelial cells is the first line of defense,
which is crucial to protect the host immune system from harmful stimuli.
Moreover, irreversible structural changes in nasal mucosal epithelial
cells can occur in response to different allergens, but the mechanism
leading to such abnormal changes has not been determined. Programmed
cell death is regulated by genes and interacts with multiple cell
signaling pathways. To explore the regulatory mechanism and signal
pathway of programmed cell death in epithelial cells of allergic
rhinitis, is helpful to clarify the pathogenesis of AR and put forward
treatment strategies. In this paper, the regulation mechanisms of
programmed cell death such as apoptosis, pyroptosis, and autophagy
occurring in epithelial cells in AR, are retrospectively summarized to
better understand the pathogenesis of AR. FIG. 1 Programmed cell death
