The DNA sensor TLR9 traffics from the endoplasmic reticulum to endolysosomal compartments where it is cleaved by resident proteases to generate a competent receptor. Activation of TLR9 by CpG-motif containing oligodeoxynucleotides (CpG ODNs) is preceded by agonist endocytosis and delivery into the endolysosomes. The events that dictate this process remain largely unknown; furthermore, it is unclear whether the receptors involved in mediating uptake of exogenous DNA are conserved for both naturally derived pathogenic DNA and synthetic ODNs. In this study, we report that peritoneal macrophages from a wild-derived inbred mouse strain, MOLF\/Ei, are hyporesponsive to CpG ODN but are fully responsive to bacterial DNA, thus implying that microbial recognition is not fully recapitulated by a synthetic analog. To identify the gene responsible for the CpG ODN defect, we have performed genome-wide linkage analysis. Using N2 backcross mice, we mapped the trait with high resolution to a single locus containing Mrc1 as the gene conferring the trait. We show that mannose receptor 1 (MRC1; CD206) is involved in CpG ODN uptake and trafficking in wild-derived MOLF\/Ei peritoneal macrophages. Furthermore, we show that other strains of wild-derived mice also require MRC1 for CpG-induced cytokine responses. These findings reveal novel functions for MRC1 and demonstrate that wild-derived mice are important and indispensable model for understanding naturally occurring regulators of inflammatory responses in innate immune pathways.<\/jats:p>","DOI":"10.4049\/jimmunol.1301438","type":"journal-article","created":{"date-parts":[[2013,11,2]],"date-time":"2013-11-02T02:58:55Z","timestamp":1383361135000},"page":"5615-5624","source":"Crossref","is-referenced-by-count":48,"title":["Mannose Receptor 1 Mediates Cellular Uptake and Endosomal Delivery of CpG-Motif Containing Oligodeoxynucleotides"],"prefix":"10.1093","volume":"191","author":[{"given":"Annie Park","family":"Moseman","sequence":"first","affiliation":[{"name":"Graduate Program in Immunology, Sackler School of Biomedical Sciences, Tufts University , Boston, MA 02111"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"E Ashley","family":"Moseman","sequence":"additional","affiliation":[{"name":"Division of Immunology, Department of Microbiology and Immunobiology, Harvard Medical School , Boston, MA 02115"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Stephen","family":"Schworer","sequence":"additional","affiliation":[{"name":"Graduate Program in Immunology, Sackler School of Biomedical Sciences, Tufts University , Boston, MA 02111"},{"name":"Medical Scientist Training Program, Tufts University , Boston, MA 02111"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Irina","family":"Smirnova","sequence":"additional","affiliation":[{"name":"Department of Integrative Physiology and Pathobiology, Tufts University , Boston, MA 02111"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Tatyana","family":"Volkova","sequence":"additional","affiliation":[{"name":"Department of Molecular Biology, Petrozavodsk State University , 185910 Petrozavodsk, Republic of Karelia,","place":["Russia"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ulrich","family":"von Andrian","sequence":"additional","affiliation":[{"name":"Division of Immunology, Department of Microbiology and Immunobiology, Harvard Medical School , Boston, MA 02115"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Alexander","family":"Poltorak","sequence":"additional","affiliation":[{"name":"Graduate Program in Immunology, Sackler School of Biomedical Sciences, Tufts University , Boston, MA 02111"},{"name":"Department of Integrative Physiology and Pathobiology, Tufts University , Boston, MA 02111"},{"name":"Graduate Program in Genetics, Sackler School of Biomedical Sciences, Tufts University , Boston, MA 02111"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"286","published-online":{"date-parts":[[2013,12,1]]},"reference":[{"key":"2025032406015385500_r1","doi-asserted-by":"crossref","first-page":"958","DOI":"10.1189\/jlb.1107775","article-title":"Synthetic oligonucleotides as modulators of inflammation","volume":"84","author":"Klinman","year":"2008","journal-title":"J.
