Neurotrophins: Neuroimmune Interactions in Human Atopic Diseases

Allergic diseases are accompanied by a variety of symptoms such as pruritus, coughing, sneezing, and watery eyes, which can result in severe physiological and even psychological impairments. The exact mechanisms of these conditions are not yet completely understood. However, recent studies demonstrated a high relevance of neurotrophins in allergic inflammation, as they induce cytokine release, mediate interaction between immune cells and neurons, and exhibit different expression levels in health and disease. In this review, we aim to give an overview of the current state of knowledge concerning the role of neurotrophins in atopic disorders such as atopic dermatitis, allergic asthma, and allergic rhinitis.

Automated summary

Allergic diseases can cause various symptoms such as itching, coughing, sneezing, and watery eyes, leading to severe physiological and psychological impairments. The mechanisms of these conditions are still not fully understood, but recent studies have shown the high relevance of neurotrophins in allergic inflammation. Neurotrophins induce cytokine release, facilitate interactions between immune cells and neurons, and show different expression levels in health and disease. In this review, the role of neurotrophins in atopic disorders like atopic dermatitis, allergic asthma, and allergic rhinitis is discussed.
