The mechanisms behind ionizing radiation-induced inflammation are not fully understood in untransformed human cells, especially at high dose exposures that can also cause cell death. Radiation-induced genotoxic stress triggers the cellular DNA damage response, and interactions between this pathway and inflammation may be crucial in determining the fate of irradiated cells. We studied how primary human vascular endothelial cells, telomeraseimmortalized foreskin microvascular cells, blood mononuclear cells, and primary skin fibroblasts respond to radiation doses from 2 to 10 Gy for up to 24 h after exposure, prior to cell death. In endothelial cells, exposure to 10 Gy, but not lower doses, caused a temporary increase in the transcription of genes coding for inflammatory factors before the activation of DNA damage response genes. This early inflammatory reaction depends on ATM activity, which coordinates the DNA damage response, and is not observed in blood cells or fibroblasts. Additionally, we saw an increase in cytokine production and adhesion molecule expression in endothelial cells. This inflammatory response may contribute to changes in the immune microenvironment of irradiated cells.<\/jats:p>","DOI":"10.1667\/rade-24-00262.1","type":"journal-article","created":{"date-parts":[[2025,9,12]],"date-time":"2025-09-12T06:00:00Z","timestamp":1757656800000},"page":"537-549","source":"Crossref","is-referenced-by-count":1,"title":["High-dose Radiation Induces an Early and Transient, ATM-dependent Inflammatory Response in Primary Human Endothelial Cells"],"prefix":"10.1667","volume":"204","author":[{"given":"Cl\u00e9ment","family":"Rouichi","sequence":"first","affiliation":[{"name":"University Grenoble Alpes, CEA, CNRS, Grenoble, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Elizabeth","family":"Chartier-Garcia","sequence":"additional","affiliation":[{"name":"University Grenoble Alpes, CEA, CNRS, Grenoble, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jean-Luc","family":"Ravanat","sequence":"additional","affiliation":[{"name":"University Grenoble Alpes, Grenoble-INP, CEA, CNRS, Grenoble, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Isabelle","family":"Testard","sequence":"additional","affiliation":[{"name":"University Grenoble Alpes, CEA, CNRS, Grenoble, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Serge M.","family":"Cand\u00e9ias","sequence":"additional","affiliation":[{"name":"University Grenoble Alpes, CEA, CNRS, Grenoble, France"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1243","reference":[{"key":"34","doi-asserted-by":"crossref","unstructured":"DE Hallahan  and S Virudachalam  \"Proc Natl Acad Sci U S A.\"  94, \"Intercellular adhesion molecule 1 knockout abrogates radiation induced pulmonary inflammation.\" 6432 (1997)","DOI":"10.1073\/pnas.94.12.6432"},{"key":"4","doi-asserted-by":"crossref","unstructured":"D Tang, R Kang, CB Coyne, et al.  \"Immunol Rev.\"  249, \"PAMPs and DAMPs: signal 0s that spur autophagy and immunity.\" 158 (2012)","DOI":"10.1111\/j.1600-065X.2012.01146.x"},{"key":"3","doi-asserted-by":"crossref","unstructured":"T Kawai  and S Akira  \"Int Immunol.\"  21, \"The roles of TLRs, RLRs and NLRs in pathogen recognition.\" 317 (2009)","DOI":"10.1093\/intimm\/dxp017"},{"key":"5","doi-asserted-by":"crossref","unstructured":"H Yanai, T Ban, Z Wang, et al.  \"Nature.\"  462, \"HMGB proteins function as universal sentinels for nucleic-acid-mediated innate immune responses.\" 99 (2009)","DOI":"10.1038\/nature08512"},{"key":"6","doi-asserted-by":"crossref","unstructured":"DSM Chatzileontiadou, H Sloane, AT Nguyen, et al.  \"Int J Mol Sci.\"  22, \"The Many Faces of CD4+ T Cells: Immunological and Structural Characteristics.\" 73 (2020)","DOI":"10.3390\/ijms22010073"},{"key":"7","doi-asserted-by":"crossref","unstructured":"S Mitchell, J Vargas, A Hoffmann,  \"WIREs Syst Biol Med.\"  8, \"Signaling via the NF\u03baB system.\" 227 (2016)","DOI":"10.1002\/wsbm.1331"},{"key":"9","doi-asserted-by":"crossref","unstructured":"EG.
