In the present study, the anti-inflammatory, anti-allergic, and skin-protective effects of saponarin were investigated to evaluate its usefulness as a functional ingredient in cosmetics. In lipopolysaccharide-induced RAW264.7 (murine macrophage) cells, saponarin (80 \u03bcM) significantly inhibited cytokine expression, including tumor necrosis factor (TNF)-\u03b1, interleukin (IL)-1\u03b2, inducible nitric oxide synthase, and cyclooxygenase (COX)-2. Saponarin (80 \u03bcM) also inhibited the phosphorylation of extracellular signal-regulated kinase (ERK) and p38 involved in the mitogen-activated protein kinase signaling pathway in RAW264.7 cells. Saponarin (40 \u03bcM) significantly inhibited \u03b2-hexosaminidase degranulation as well as the phosphorylation of signaling effectors (Syk, phospholipase C\u03b31, ERK, JNK, and p38) and the expression of inflammatory mediators (tumor necrosis factor [TNF]-\u03b1, IL-4, IL-5, IL-6, IL-13, COX-2, and Fc\u03b5RI\u03b1\/\u03b3) in DNP-IgE- and DNP-BSA-stimulated RBL-2H3 (rat basophilic leukemia) cells. In addition, saponarin (100 \u03bcM) significantly inhibited the expression of macrophage-derived chemokine, thymus and activation-regulated chemokine, IL-33, thymic stromal lymphopoietin, and the phosphorylation of signaling molecules (ERK, p38 and signal transducer and activator of transcription 1 [STAT1]) in TNF-\u03b1- and interferon (IFN)-\u03b3-stimulated HaCaT (human immortalized keratinocyte) cells. Saponarin (100 \u03bcM) also significantly induced the expression of hyaluronan synthase-3, aquaporin 3, and cathelicidin antimicrobial peptide (LL-37) in HaCaT cells, which play an important role as skin barriers. Saponarin remarkably inhibited the essential factors involved in the inflammatory and allergic responses of RAW264.7, RBL-2H3, and HaCaT cells, and induced the expression of factors that function as physical and chemical skin barriers in HaCaT cells. Therefore, saponarin could potentially be used to prevent and relieve immune-related skin diseases, including atopic dermatitis.<\/jats:p>","DOI":"10.3390\/ijms22168431","type":"journal-article","created":{"date-parts":[[2021,8,5]],"date-time":"2021-08-05T09:35:32Z","timestamp":1628156132000},"page":"8431","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":58,"title":["Anti-Inflammatory and Anti-Allergic Effects of Saponarin and Its Impact on Signaling Pathways of RAW 264.7, RBL-2H3, and HaCaT Cells"],"prefix":"10.3390","volume":"22","author":[{"given":"Seon-Young","family":"Min","sequence":"first","affiliation":[{"name":"Department of Medicinal Biosciences, Research Institute for Biomedical & Health Science, College of Biomedical and Health Science, Konkuk University, 268 Chungwon-daero, Chungju-si 27478, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6133-1127","authenticated-orcid":false,"given":"Che-Hwon","family":"Park","sequence":"additional","affiliation":[{"name":"Department of Medicinal Biosciences, Research Institute for Biomedical & Health Science, College of Biomedical and Health Science, Konkuk University, 268 Chungwon-daero, Chungju-si 27478, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hye-Won","family":"Yu","sequence":"additional","affiliation":[{"name":"Department of Medicinal Biosciences, Research Institute for Biomedical & Health Science, College of Biomedical and Health Science, Konkuk University, 268 Chungwon-daero, Chungju-si 27478, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8392-4772","authenticated-orcid":false,"given":"Young-Jin","family":"Park","sequence":"additional","affiliation":[{"name":"Department of Medicinal Biosciences, Research Institute for Biomedical & Health Science, College of Biomedical and Health Science, Konkuk University, 268 Chungwon-daero, Chungju-si 27478, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2021,8,5]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"612","DOI":"10.3892\/br.2017.909","article-title":"Drug development: Lessons from nature","volume":"6","author":"Mathur","year":"2017","journal-title":"Biomed.
