摘要

The nervous and immune systems cooperate to regulate mucosal barrier integrity. Nevertheless, whether enteric neurons establish neuroepithelial interactions to coordinate immunity remains elusive. Here, we identified neuroepithelial interactions that differentially control intestinal type 1 and type 2 immunity. Gut epithelial cells expressed vasoactive intestinal peptide (VIP) receptor 1 (VIPR1), and chemogenetic modulation of enteric VIPergic neurons led to altered epithelial-derived cytokines. Epithelial-intrinsic deletion of Vipr1 resulted in diminished type 1 immunity, including reduced type 1 alarmins and intraepithelial lymphocytes. In contrast, epithelial Vipr1 deficiency led to enhanced type 2 immunity, comprising increased type 2 alarmins, tuft cells and activated group 2 innate lymphoid cells. Disruption of neuroepithelial VIP–VIPR1 interactions resulted in increased susceptibility to invasive bacterial infection, which contrasted with enhanced resistance to parasite infection. Our work identifies a multi-tissue axis that controls type 1 and type 2 immunity, deciphering how neuroepithelial interactions distinctively set gut immunity programs.
