NRP1 downregulation correlates with enhanced ILC2 responses during IL-33 challenge
Group 2 innate lymphoid cells (ILC2s) play critical roles in driving the pathogenesis of allergic airway inflammation. The mechanisms underlying the regulation of ILC2s remain to be fully understood. Here, we identified neuropilin-1 (NRP1) as a surface marker of ILC2s in response to IL-33 stimulation. NRP1 was abundantly expressed in ILC2s from lung under steady state, which was significantly reduced upon IL-33 stimulation. ILC2s with high expression of NRP1 (NRP1high) displayed lower response to IL-33, as compared with NRP1low ILC2s. Transcriptional profiling and flow cytometric analysis showed that downregulation of AKT–mTOR signalling participated in the diminished functionality of NRP1high ILC2s. These observations revealed a potential role of NRP1 in ILC2s responses under allergic inflammatory condition.
期刊介绍：
Immunology is one of the longest-established immunology journals and is recognised as one of the leading journals in its field. We have global representation in authors, editors and reviewers.
Immunology publishes papers describing original findings in all areas of cellular and molecular immunology. High-quality original articles describing mechanistic insights into fundamental aspects of the immune system are welcome. Topics of interest to the journal include: immune cell development, cancer immunology, systems immunology/omics and informatics, inflammation, immunometabolism, immunology of infection, microbiota and immunity, mucosal immunology, and neuroimmunology.
The journal also publishes commissioned review articles on subjects of topical interest to immunologists, and commissions in-depth review series: themed sets of review articles which take a 360° view of select topics at the heart of immunological research.
