Being continuously exposed to both harmless antigens and potentially threatening pathogens, the intestinal mucosa requires the integration of multiple signals for balancing immune responses. This integration is certainly supported by tissue-resident intestinal mesenchymal cells (IMCs), yet the molecular mechanisms whereby IMCs contribute to these events remain largely undefined. Recent studies using single-cell profiling technologies indicated a previously unappreciated heterogeneity of IMCs and provided further knowledge which will help to understand dynamic interactions between IMCs and hematopoietic cells of the intestinal mucosa. In this review, we focus on recent findings on the immunological functions of IMCs: On one hand, we discuss the steady-state interactions of IMCs with epithelial cells and hematopoietic cells. On the other hand, we summarize our current knowledge about the contribution of IMCs to the development of intestinal inflammatory conditions, such as infections, inflammatory bowel disease, and fibrosis. By providing a comprehensive list of cytokines and chemokines produced by IMCs under homeostatic and inflammatory conditions, we highlight the significant immunomodulatory and tissue niche forming capacities of IMCs.<\/jats:p>","DOI":"10.3390\/ijms23095181","type":"journal-article","created":{"date-parts":[[2022,5,6]],"date-time":"2022-05-06T14:49:38Z","timestamp":1651848578000},"page":"5181","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":22,"title":["Tissue Niches Formed by Intestinal Mesenchymal Stromal Cells in Mucosal Homeostasis and Immunity"],"prefix":"10.3390","volume":"23","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-0481-4138","authenticated-orcid":false,"given":"Maria","family":"Pasztoi","sequence":"first","affiliation":[{"name":"Institute of Allergy Research, Centre of Allergy and Environment, Technical University and Helmholtz Centre Munich, Ingolstaedter Landstrasse 1, 85764 Neuherberg, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Caspar","family":"Ohnmacht","sequence":"additional","affiliation":[{"name":"Institute of Allergy Research, Centre of Allergy and Environment, Technical University and Helmholtz Centre Munich, Ingolstaedter Landstrasse 1, 85764 Neuherberg, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2022,5,6]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"35","DOI":"10.1016\/bs.pmbts.2015.07.012","article-title":"Microenvironment Matters: Unique Conditions Within Gut-Draining Lymph Nodes Favor Efficient De Novo Induction of Regulatory T Cells","volume":"136","author":"Pasztoi","year":"2015","journal-title":"Prog.
