Immunocompromised mice were randomly divided into five groups: uninfected control, and inoculation with conidia from Aspergillus fumigatus, Aspergillus flavus, Aspergillus niger, and Aspergillus terreus. Conidia (2 \u00d7 106 cells\/mL) were administered intravenously via tail vein injection. Three mice from each group were euthanised at each time point (6 h, 12 h, 18 h, 24 h, and 48 h) after inoculation. Urine and blood were collected for analysis using a double-sandwich ELISA using 1D2 and 4E4. Liver, spleen, and kidney tissues were harvested for tissue staining. The levels of liver injury in the IA mice progressively increased with time after inoculation with Aspergillus conidia. Following inoculation with A. fumigatus, swollen conidia were identified in the spleen, as well as antigens in blood after 18 h. Hyphae were detected in the spleen, liver, and kidney after 48 h. For A. flavus, the antibodies detected hyphae in the liver and spleen as well as circulating antigens in blood samples 48 h after inoculation. Tissue injury was observed in the mice inoculated with A. terreus and A. niger, but there was no evidence of fungal invasion or antigens in the blood. Antigens were not detectable in mouse urine but could be detected in glomeruli of the kidney by immunofluorescence. In conclusion, the mAb-based antigen detection double-sandwich ELISA results were consistent with the IHC results in this study. Novel monoclonal antibodies 1D2 and 4E4 can serve as tools for the early identification of IA in mice infected by A. fumigatus and A. flavus. This study also suggests the potential usefulness of this approach in human disease.<\/jats:p>","DOI":"10.3390\/jof10120832","type":"journal-article","created":{"date-parts":[[2024,12,4]],"date-time":"2024-12-04T10:07:10Z","timestamp":1733306830000},"page":"832","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Novel Monoclonal Antibodies 1D2 and 4E4 Against Aspergillus Glycoprotein Antigens Detect Early Invasive Aspergillosis in Mice"],"prefix":"10.3390","volume":"10","author":[{"given":"Xihua","family":"Lian","sequence":"first","affiliation":[{"name":"Department of Pathology and Biomedical Science, University of Otago, Christchurch 8140, New Zealand"},{"name":"Department of Ultrasound Medicine, The Second Clinical Medical School, Fujian Medical University, Quanzhou 362000, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3246-2491","authenticated-orcid":false,"given":"Amy","family":"Scott-Thomas","sequence":"additional","affiliation":[{"name":"Department of Pathology and Biomedical Science, University of Otago, Christchurch 8140, New Zealand"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"John G.","family":"Lewis","sequence":"additional","affiliation":[{"name":"Department of Pathology and Biomedical Science, University of Otago, Christchurch 8140, New Zealand"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Madhav","family":"Bhatia","sequence":"additional","affiliation":[{"name":"Department of Pathology and Biomedical Science, University of Otago, Christchurch 8140, New Zealand"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Stephen T.","family":"Chambers","sequence":"additional","affiliation":[{"name":"Department of Pathology and Biomedical Science, University of Otago, Christchurch 8140, New Zealand"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2024,12,2]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"872","DOI":"10.1016\/j.bbmt.2014.03.004","article-title":"Incidence and Outcome of Invasive Fungal Diseases after Allogeneic Stem Cell Transplantation: A Prospective Study of the Gruppo Italian Trapianto Midollo Osseo (GITMO)","volume":"20","author":"Girmenia","year":"2014","journal-title":"Biol.
