Thus, development of novel therapeutics with a different mechanism of action is urgently needed. A recombinant vesicular stomatitis virus (VSV) lacking its G gene ($ \\Delta $G) and instead encoding human CD4 and CXCR4 is known to control CXCR4-tropic (X4) HIV-1 infection in culture. To test the value of such a recombiant virus more, we constructed VSV $ \\Delta $ Gs expressing CD4 and CCR5 with or without modified dendritic cellspecific ICAM-3 grabbing nonintegrin (DC-SIGN) from rhesus macaques and examined if these viruses were effective against simian immunodeficiency virus (SIV) infection in culture. Our data demonstrated that the VSV $ \\Delta $ Gs specifically infected and killed SIVinfected cells, resulting in long-term control of SIV infection in vitro. These results indicate that such VSVs have potential for novel anti-HIV-1 therapeutic candidates. In addition, to determine therapeutic value of anti-HIV-1 drug candidates, it is crucial to test them in animal models before clinical trials. Severe combined immunodeficiency (SCID) mice reconstituted with human peripheral blood mononuclear cells (PBMCs),termed hu-PBLSCID mice or humanized mice, have served as such a valuable small animal model. However, there was a limitation on use of this model because X4 HIV-1 does not efficiently infect these mice due to, at least in part, relatively low levels of expression of the CXCR4 coreceptor. To solve this problem, we generated human interleukin (IL)-4-transgenic huPBL-SCID mice that spontaneously synthesized human IL-4 which has been shown to enhance CXCR4 expression and promote X4 HIV-1 infection in vitro and investigated if X4 virus efficiently infected these mice. Our study showed that in vivo synthesis of human IL-4 augmented CXCR4 expression on human CD4+ T cells and led to productive X4 HIV-1 infection, and that the in vivo infection was definitely blocked by CXCR4 antagonist administration. These data indicate that human IL-4-transgenic hu-PBL-SCID mice can be a useful model for the X4 HIV-1 study and the testing of anti-X4 HIV-1 drug candidates.", "subitem_description_type": "Other"}, {"subitem_description": "論文", "subitem_description_type": "Other"}]}, "item_1617186643794": {"attribute_name": "Publisher", "attribute_value_mlt": [{"subitem_1522300295150": "ja", "subitem_1522300316516": "琉球医学会"}, {"subitem_1522300295150": "en", "subitem_1522300316516": "Ryukyu Medical Association"}]}, "item_1617186702042": {"attribute_name": "Language", "attribute_value_mlt": [{"subitem_1551255818386": "jpn"}]}, "item_1617186920753": {"attribute_name": "Source Identifier", "attribute_value_mlt": [{"subitem_1522646500366": "ISSN", "subitem_1522646572813": "1346-888X"}, {"subitem_1522646500366": "ISSN", "subitem_1522646572813": "0289-1530"}, {"subitem_1522646500366": "NCID", "subitem_1522646572813": "AN10369445"}]}, "item_1617186941041": {"attribute_name": "Source Title", "attribute_value_mlt": [{"subitem_1522650068558": "ja", "subitem_1522650091861": "琉球医学会誌 = Ryukyu Medical Journal"}]}, "item_1617187056579": {"attribute_name": "Bibliographic Information", "attribute_value_mlt": [{"bibliographicIssueDates": {"bibliographicIssueDate": "2008", "bibliographicIssueDateType": "Issued"}, "bibliographicIssueNumber": "1・2", "bibliographicPageEnd": "9", "bibliographicPageStart": "1", "bibliographicVolumeNumber": "27"}]}, "item_1617258105262": {"attribute_name": "Resource Type", "attribute_value_mlt": [{"resourcetype": "journal article", "resourceuri": "http://purl.org/coar/resource_type/c_6501"}]}, "item_1617265215918": {"attribute_name": "Version Type", "attribute_value_mlt": [{"subitem_1522305645492": "VoR", "subitem_1600292170262": "http://purl.org/coar/version/c_970fb48d4fbd8a85"}]}, "item_1617605131499": {"attribute_name": "File", "attribute_type": "file", "attribute_value_mlt": [{"accessrole": "open_access", "download_preview_message": "", "file_order": 0, "filename": "v27p1.pdf", "future_date_message": "", "is_thumbnail": false, "mimetype": "", "size": 0, "url": {"objectType": "fulltext", "url": "https://u-ryukyu.repo.nii.ac.jp/record/2015586/files/v27p1.pdf"}, "version_id": "5eb88b04-6c0c-4514-80e3-748b7ed56920"}]}, "item_title": "[総説]HIV-1感染に対する新規治療法及び感染実験小動物モデルの開発", "item_type_id": "15", "owner": "1", "path": ["1642838224750", "1642838412624"], "permalink_uri": "http://hdl.handle.net/20.500.12000/0002015586", "pubdate": {"attribute_name": "PubDate", "attribute_value": "2010-02-23"}, "publish_date": "2010-02-23", "publish_status": "0", "recid": "2015586", "relation": {}, "relation_version_is_last": true, "title": ["[総説]HIV-1感染に対する新規治療法及び感染実験小動物モデルの開発"], "weko_shared_id": -1}
