Role of dendritic cell‑derived exosomes in allergic rhinitis (Review)

Abstract

Allergic rhinitis (AR) is a common pathological condition in otorhinolaryngology. Its prevalence has been increasing worldwide and is becoming a major burden to the world population. dendritic cells (dcs) are typically activated and matured after capturing, phagocytosing, and processing allergens during the immunopathogenesis of AR. In addition, the process of dc activation and maturation is accompanied by the production of exosomes, which are cell-derived extracellular vesicles (EVs) that can carry proteins, lipids, nucleic acids, and other cargoes involved in intercellular communication and material transfer. In particular, dc-derived exosomes (dex) can participate in allergic immune responses, where the biological substances carried by them can have potentially important implications for both the pathogenesis and treatment of AR. dex can also be exploited to carry anti-allergy agents to effectively treat AR. This provides a novel method to explore the pathogenesis of and treatment strategies for AR further. Therefore, the present review focuses on the origin, composition, function, and biological characteristics of dcs, exosomes, and dex, in addition to the possible relationship between dex and AR.

Exosomes: a promising avenue for cancer diagnosis beyond treatment

“…This molecular exchange enables cells to coordinate and regulate a wide array of cellular activities and responses. For instance, immune cells utilize exosomes to convey signals that orchestrate immune responses, while cancer cells exploit exosome communication to promote tumor growth and metastasis ( De La Pena et al, 2009 ; Kang et al, 2023 ).…”

Research progress of exosomes in the angiogenesis of digestive system tumour

“…In addition to being targets, exosomes can be carriers. Compared with synthetic nanoparticles, exosomes are specific, safe, of cell-origin, and natural carriers that have a long half-life and nonimmunogenic properties for drug delivery systems [ 178 – 180 ]. Specifically, exosomes have a lipid bilayer and a hydrophilic core; thus, they can transmit both lipid- and water-soluble drugs [ 181 ].…”
