During infection, L. pneumophila replicates intracellularly in macrophages. The involvement of host micro RNAs (miRNAs) in L. pneumophila infection is not fully understood.\nMethods: The human macrophage-like cell line U937 was infected with L. pneumophila. The levels of miRNA and messenger RNA (mRNAs) were measured using reverse transcriptase polymerase chain reaction. Release of lactate dehydrogenase was used to evaluate cytotoxicity The expression of RICTOR and related proteins was examined by western blotting of cell lysates.\nResults: L. pneumophila infection upregulated the expression of miR-218 and the host genes SLIT2 and SLIT3 in U937 cells. The expression of RICTOR, a component of the mechanistic target of rapamycin complex 2 (mTORC2), decreased during L. pneumophila infection. RICTOR protein expression was inhibited by the overexpression of miR-218, whereas knockdown of miR-218 restored the downregulation of RICTOR by L. pneumophila . L. pneumophila infection induced the expression of the proinflammatory cytokines IL-6 and TNF alpha, which was modulated by knockdown of miR-218 or RICTOR.\nConclusions: Our study revealed the involvement of miR-218 in regulating the inflammatory response of macrophages against L. pneumophila infection. These findings suggest potential novel roles for miR-218 and RICTOR as therapeutic targets of L. pneumophila infection.\n","subitem_description_language":"en","subitem_description_type":"Other"}]},"item_5_dissertation_number_55":{"attribute_name":"学位授与番号","attribute_value_mlt":[{"subitem_dissertationnumber":"甲総研第493号"}]},"item_5_publisher_23":{"attribute_name":"公開者・出版者","attribute_value_mlt":[{"subitem_publisher":"Elsevier Inc.","subitem_publisher_language":"en"},{"subitem_publisher":"鹿児島大学","subitem_publisher_language":"ja"},{"subitem_publisher":"カゴシマ ダイガク","subitem_publisher_language":"ja-Kana"}]},"item_5_relation_11":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"10.1016/j.bbrc.2018.11.093","subitem_relation_type_select":"DOI"}}]},"item_5_relation_13":{"attribute_name":"情報源","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_text":"Biochemical and Biophysical Research Communications"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://www.sciencedirect.com/journal/biochemical-and-biophysical-research-communications","subitem_relation_type_select":"URI"}}]},"item_5_rights_12":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"© 2018 Elsevier Inc.
