Most current treatments primarily consist of inhalable steroids, which are not without adverse effects. Recently, there has been growing interest in alternative approaches to asthma management. In this study, we investigated the anti-asthmatic effects of the non-steroidal compound CycloZ using acute and chronic mouse models of asthma. Allergic reactions were induced with house dust mite (HDM) extract, and CycloZ or fluticasone propionate (FP) was administered orally or intranasally, respectively. CycloZ significantly ameliorated the HDM-induced robust expression of Th2 cytokines in both models. CycloZ also decreased immune cell infiltration into the lungs and reduced IL-4 and IL-13 cytokine levels in bronchoalveolar lavage fluid (BALF). Moreover, CycloZ greatly attenuated the activation of the TLR-4 pathway, which is involved in HDM recognition and signaling. The beneficial effects of CycloZ were comparable to or even superior to the current steroid treatment, FP, suggesting that CycloZ could be a promising new option for asthma therapy.<\/jats:p>","DOI":"10.3390\/cells13232034","type":"journal-article","created":{"date-parts":[[2024,12,9]],"date-time":"2024-12-09T11:16:48Z","timestamp":1733743008000},"page":"2034","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["CycloZ Suppresses TLR4-Driven Inflammation to Reduce Asthma-Like Responses in HDM-Exposed Mouse Models"],"prefix":"10.3390","volume":"13","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-0005-6886","authenticated-orcid":false,"given":"Dohyun","family":"Lee","sequence":"first","affiliation":[{"name":"R&D Center, NovMetaPharma Co., Ltd., Pohang 37668, Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jongsu","family":"Jeon","sequence":"additional","affiliation":[{"name":"R&D Center, NovMetaPharma Co., Ltd., Pohang 37668, Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Seoyeong","family":"Baek","sequence":"additional","affiliation":[{"name":"R&D Center, NovMetaPharma Co., Ltd., Pohang 37668, Republic of Korea"},{"name":"School of Life Science, Handong Global University, Pohang 37554, Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Onyu","family":"Park","sequence":"additional","affiliation":[{"name":"R&D Center, NovMetaPharma Co., Ltd., Pohang 37668, Republic of Korea"},{"name":"School of Life Science, Handong Global University, Pohang 37554, Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8938-751X","authenticated-orcid":false,"given":"Ah-Ram","family":"Kim","sequence":"additional","affiliation":[{"name":"School of Life Science, Handong Global University, Pohang 37554, Republic of Korea"},{"name":"Department of Advanced Convergence, Handong Global University, Pohang 37554, Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Myoung-Sool","family":"Do","sequence":"additional","affiliation":[{"name":"School of Life Science, Handong Global University, Pohang 37554, Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hoe-Yune","family":"Jung","sequence":"additional","affiliation":[{"name":"R&D Center, NovMetaPharma Co., Ltd., Pohang 37668, Republic of Korea"},{"name":"School of Interdisciplinary Bioscience and Bioengineering, Pohang University of Science and Technology (POSTECH), Pohang 37673, Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2024,12,9]]},"reference":[{"key":"ref_1","unstructured":"National Heart, Lung, and Blood Institute (2024, October 14).
