The role of neuroimmunomodulation in allergic diseases is a research hotspot in recent years. Allergic rhinitis（AR） is caused by overactive immune response to a foreign antigen in nasal mucosa. Immune cells release inflammatory mediators（including histamine, cytokines and neurotrophins）, which directly activate peripheral neurons to mediate nasal congestion, itching, sneezing, and other hyperresponsive symptoms. Upon activation, these peripheral neurons release neurotransmitters （including acetylcholine and norepinephrine） and neuropeptides（including calcitonin gene-related peptide, substance P and vasoactive intestinal peptide） that directly act on immune cells to drive allergic inflammation. Neuro-immune signaling may play a significant role in the pathophysiology of AR. Therefore, a better understanding of these cellular and molecular neuro-immune interactions may inspire the discovery of new targets and novel therapies.
