Chemokines and chemokine receptors in allergic rhinitis: from mediators to potential therapeutic targets

Zhan Li et al. Eur Arch Otorhinolaryngol. 2022 Nov.

Abstract

Allergic rhinitis (AR) is an immune-mediated inflammatory condition characterized by immune cell infiltration of the nasal mucosa, with symptoms of rhinorrhea, sneezing, nasal obstruction, and itchiness. Currently, common medication for AR is anti-inflammatory treatment including intranasal steroids, oral, or intranasal anti-histamines, and immunotherapy. These strategies are effective to the majority of patients with AR, but some patients under medication cannot achieve symptom relieve and suffer from bothersome side effects, indicating a demand for novel anti-inflammatory treatment as alternatives. Chemokines, a complex superfamily of small, secreted proteins, were initially recognized for their chemotactic effects on various immune cells. Chemokines constitute both physiological and inflammatory cell positioning systems and mediate cell localization to certain sites via interaction with their receptors, which are expressed on responding cells. Chemokines and their receptors participate in the sensitization, early phase response, and late phase response of AR by promoting inflammatory cell recruitment, differentiation, and allergic mediator release. In this review, we first systemically summarize chemokines and chemokine receptors that are important in AR pathophysiology and then discuss potential strategies targeting chemokines and their receptors for AR therapy.

Keywords: Allergic rhinitis; Cell infiltration; Chemokine; Chemokine receptor; Immune inflammation; Therapeutic target.
