Cell. Infect.

It is a significant veterinary and human pathogen capable of infecting both humans and animals, with substantial impacts on public health, human well-being, and the economic development of the livestock and poultry farming industry. Small non-coding RNAs (sRNAs), typically 50\u2013500 nucleotides (nt) in length, have been identified in various bacteria, including <jats:italic>Escherichia coli<\/jats:italic>, <jats:italic>Brucella<\/jats:italic>, <jats:italic>Pseudomonas aeruginosa<\/jats:italic>, and <jats:italic>Salmonella<\/jats:italic>. These sRNAs play crucial roles in regulating diverse physiological processes within bacteria. This review emphasizes recent advances in understanding how sRNAs regulate the virulence of <jats:italic>Salmonella<\/jats:italic> spp, such as the discovery of novel sRNAs like SaaS and new regulatory mechanisms of known sRNAs like RyhB-1\/RyhB-2 and SdsR\/Spot 42. It also outlines critical future directions, including exploring the multifaceted functions of sRNAs in lifestyle or infection phase transitions, fully elucidating their roles in regulating the host immune response, studying the combined actions of multiple sRNAs on host pathogenesis and expanding research to more <jats:italic>Salmonella<\/jats:italic> serotypes and diverse animal models. Through these efforts, this review aims to enhance our understanding of <jats:italic>Salmonella<\/jats:italic> sRNAs and their infection mechanisms.<\/jats:p>","DOI":"10.3389\/fcimb.2025.1503337","type":"journal-article","created":{"date-parts":[[2025,5,15]],"date-time":"2025-05-15T05:30:00Z","timestamp":1747287000000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":9,"title":["Advances in sRNA-mediated regulation of Salmonella infection in the host"],"prefix":"10.3389","volume":"15","author":[{"given":"Ting","family":"He","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yonghui","family":"Ding","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yuling","family":"Sun","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tiansen","family":"Li","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1965","published-online":{"date-parts":[[2025,5,15]]},"reference":[{"key":"B1","doi-asserted-by":"publisher","first-page":"e00333","DOI":"10.1128\/jb.00333-22","article-title":"Small RNAs Activate Salmonella Pathogenicity Island 1 by Modulating mRNA Stability through the hilD mRNA 3\u2032 Untranslated Region","volume":"205","author":"Abdulla","year":"2023","journal-title":"J.
