Current treatments focus on preventing LPS from interacting with its receptor Toll-like receptor 4 (TLR4) and reducing inflammation. However, our body has a natural defense mechanism: reticuloendothelial cells in the liver rapidly degrade and inactivate much of the circulating LPS within minutes. But this LPS clearance mechanism is not perfect. Excessive LPS that escape this clearance mechanism cause systemic inflammatory damage through TLR4. Despite its importance, the role of reticuloendothelial cells in LPS elimination is not well-studied, especially regarding the specific cells, receptors, and mechanisms involved. This gap hampers the development of effective therapies for endotoxemia and related diseases. This review consolidates the current understanding of LPS clearance, narrates known and explores potential mechanisms, and discusses the relationship between LPS clearance and LPS signaling. It also aims to highlight key insights that can guide the development of strategies to reduce circulating LPS by way of bolstering host defense mechanisms. Ultimately, we seek to provide a foundation for future research that could lead to innovative approaches for enhancing the body\u2019s natural ability to clear LPS and thereby lower the risk of endotoxin-related inflammatory diseases, including sepsis.<\/jats:p>","DOI":"10.3390\/cells13181590","type":"journal-article","created":{"date-parts":[[2024,9,23]],"date-time":"2024-09-23T03:36:38Z","timestamp":1727062598000},"page":"1590","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":52,"title":["The Battle of LPS Clearance in Host Defense vs. Inflammatory Signaling"],"prefix":"10.3390","volume":"13","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-4146-0543","authenticated-orcid":false,"given":"Pankaj","family":"Kumar","sequence":"first","affiliation":[{"name":"Department of Internal Medicine, College of Medicine, The Ohio State University, Columbus, OH 43210, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7342-5796","authenticated-orcid":false,"given":"Evan A.","family":"Schroder","sequence":"additional","affiliation":[{"name":"Department of Biochemistry, University of Nebraska, Lincoln, NE 68588, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Murugesan V.
