The innate immune system is an evolutionarily conserved defence strategy. Complex organisms have developed various cellular processes to respond to and recognise not only infections, i.e., pathogen-associated molecular patterns (PAMPs), but also to sense injury and tissue dysfunctions, i.e., damage-associated molecular patterns (DAMPs). Mis-localized self-DNA can be sensed as DAMP by specific DNA-sensing pathways, and self-DNA chronic exposure can be detrimental to the organisms. Here, we investigate the effects of dietary delivered self-DNA in the nematode Caenorhabditis elegans. The hermaphrodite worms were fed on Escherichia coli genomic libraries: a C. elegans library (self) and a legume (Medicago truncatula) library (non-self). We show that the self-library diet affects embryogenesis, larval development and gametogenesis. DNA damage and activation of p53\/CEP-1-dependent apoptosis occur in gonadal germ cells. Studies of self-DNA exposure in this model organism were not pursued up to now. The genetic tractability of C. elegans will help to identify the basic molecular pathways involved in such mechanisms. The specificity of the adverse effects associated with a self-DNA enriched diet suggests applications in biological pest control approaches.<\/jats:p>","DOI":"10.3390\/biology11020262","type":"journal-article","created":{"date-parts":[[2022,2,9]],"date-time":"2022-02-09T01:03:40Z","timestamp":1644368620000},"page":"262","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":12,"title":["Self-DNA Exposure Induces Developmental Defects and Germline DNA Damage Response in Caenorhabditis elegans"],"prefix":"10.3390","volume":"11","author":[{"given":"Marcello","family":"Germoglio","sequence":"first","affiliation":[{"name":"Institute of Biosciences and BioResources, National Research Council, Via Pietro Castellino 111, 80131 Napoli, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2121-8522","authenticated-orcid":false,"given":"Adele","family":"Adamo","sequence":"additional","affiliation":[{"name":"Institute of Biosciences and BioResources, National Research Council, Via Pietro Castellino 111, 80131 Napoli, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1288-8708","authenticated-orcid":false,"given":"Guido","family":"Incerti","sequence":"additional","affiliation":[{"name":"Department of Agri-Food, Animal and Environmental Sciences (DI4A), University of Udine, 33100 Udine, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Fabrizio","family":"Carten\u00ec","sequence":"additional","affiliation":[{"name":"Department of Agricultural Sciences, Universit\u00e0 degli Studi di Napoli Federico II, 80055 Portici, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Silvia","family":"Gigliotti","sequence":"additional","affiliation":[{"name":"Institute of Biosciences and BioResources, National Research Council, Via Pietro Castellino 111, 80131 Napoli, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Aurora","family":"Storlazzi","sequence":"additional","affiliation":[{"name":"Institute of Biosciences and BioResources, National Research Council, Via Pietro Castellino 111, 80131 Napoli, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1132-2625","authenticated-orcid":false,"given":"Stefano","family":"Mazzoleni","sequence":"additional","affiliation":[{"name":"Department of Agricultural Sciences, Universit\u00e0 degli Studi di Napoli Federico II, 80055 Portici, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2022,2,8]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"79","DOI":"10.1146\/annurev-immunol-070119-115052","article-title":"Innate Immune Response to Cytoplasmic DNA: Mechanisms and Diseases","volume":"38","author":"Hu","year":"2020","journal-title":"Annu.
