Abstract

Group 2 innate lymphoid cells (ILC2s) regulate inflammation, tissue repair and metabolic homeostasis, and are activated by host-derived cytokines and alarmins. Discrete subsets of immune cells integrate nervous system cues, but it remains unclear whether neuron-derived signals control ILC2s. Here we show that neuromedin U (NMU) in mice is a fast and potent regulator of type 2 innate immunity in the context of a functional neuron-ILC2 unit. We found that ILC2s selectively express neuromedin U receptor 1 (Nmur1), and mucosal neurons express NMU. Cell-autonomous activation of ILC2s with NMU resulted in immediate and strong NMUR1-dependent production of innate inflammatory and tissue repair cytokines. NMU controls ILC2s downstream of extracellular signal-regulated kinase and calcium-influx-dependent activation of both calcineurin and nuclear factor of activated T cells (NFAT). NMU treatment in vivo resulted in immediate protective type 2 responses. Accordingly, ILC2-autonomous ablation of Nmur1 led to impaired type 2 responses and poor control of worm infection. Notably, mucosal neurons were found adjacent to ILC2s, and these neurons directly sensed worm products and alarmins to induce NMU and to control innate type 2 cytokines. Our work reveals that neuron-ILC2 cell units confer immediate tissue protection through coordinated neuroimmune sensory responses.

  • Neuromedin U initiates type 2 immunity, while αCGRP antagonizes type 2 immunity in the gut mucosa.

    “For example, activation of type 2 innate lymphoid cells (ILC2) in the gut mucosa is regulated by neuronally-derived peptides, with neuromedin U initiating102, and α-calcitonin gene-related peptide (αCGRP) antagonizing, type 2 immunity103.”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
