Neuroimmune Interactions in the Lung.

Abstract

Barrier tissues are highly innervated by sensory and autonomic nerves that are positioned in close proximity to both stromal and immune cell populations. Together with a growing awareness of the far-reaching consequences of neuroimmune interactions, recent studies have uncovered key mechanisms through which they contribute to organ homeostasis and immunity. It has also become clear that dysregulation of such interactions is implicated in the development of chronic lung diseases. This review describes the characteristics of the lung nervous system and discusses the molecular mechanisms that underlie lung neuroimmune interactions in infection and disease. We have contextualized the current literature and identified opportune areas for further investigation. Indeed, both the lung-brain axis and local neuroimmune interactions hold enormous potential for the exploration and development of novel therapeutic strategies targeting lung diseases.
