Erianin (Eri) is an ideal drug candidate for inhibiting proliferation and inducing apoptosis in the treatment of psoriasis. However, Eri\u2019s poor water solubility and low penetration activity across the skin hinder its application in local medicine. In this study, we developed a novel photo-responsive dendritic mesoporous silica nanoparticle-based carrier to deliver erianin, improved its bioavailability, and achieved sustained-release effects. Spiropyran (SP), 3-aminopropyltriethoxysilane (APTES), and perfluorodecyltriethoxysilane (PFDTES) were conjugated to the outer surface, which allowed Eri to be released in response to UV radiation. The physicochemical properties of photo-responsive dendritic mesoporous silica nanoparticles (Eri-DMSN@FSP) were characterized via multiple techniques, such as using a Fourier-transform infrared spectrometer, a high-resolution transmission electron microscope, and nuclear magnetic resonance (NMR) spectroscopy. The anti-proliferative properties and light-triggered release of erianin-loaded photo-responsive dendritic mesoporous silica nanoparticles were assessed via the MTT assay and a drug release study in vitro. Erianin-loaded photo-responsive dendritic mesoporous silica nanoparticles (UV) exhibit a significantly enhanced HaCat cell-inhibiting efficacy compared to other formulations, as demonstrated by their extremely low cell viability of 10.0% (concentration: 500 mg\/mL), indicating their capability to release a drug that responds to UV radiation. The cellular uptake of photo-responsive dendritic mesoporous silica nanoparticles (DMSN@FSP) was observed via confocal laser scanning microscopy (CLSM). These experimental results show that Eri-DMSN@FSP could be effectively endocytosed into cells and respond to ultraviolet light to release Eri, achieving a more effective psoriasis treatment. Therefore, this drug delivery system may be a promising strategy for addressing the question of Eri\u2019s delivery and psoriasis therapy.<\/jats:p>","DOI":"10.3390\/molecules27196328","type":"journal-article","created":{"date-parts":[[2022,9,28]],"date-time":"2022-09-28T01:51:49Z","timestamp":1664329909000},"page":"6328","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":15,"title":["Erianin-Loaded Photo-Responsive Dendrimer Mesoporous Silica Nanoparticles: Exploration of a Psoriasis Treatment Method"],"prefix":"10.3390","volume":"27","author":[{"given":"Huanan","family":"Yu","sequence":"first","affiliation":[{"name":"School of Bioscience and Bioengineering, South China University of Technology, Guangzhou 510006, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yuanqi","family":"Liu","sequence":"additional","affiliation":[{"name":"School of Bioscience and Bioengineering, South China University of Technology, Guangzhou 510006, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Fang","family":"Zheng","sequence":"additional","affiliation":[{"name":"School of Bioscience and Bioengineering, South China University of Technology, Guangzhou 510006, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Wenyu","family":"Chen","sequence":"additional","affiliation":[{"name":"School of Bioscience and Bioengineering, South China University of Technology, Guangzhou 510006, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kun","family":"Wei","sequence":"additional","affiliation":[{"name":"School of Bioscience and Bioengineering, South China University of Technology, Guangzhou 510006, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2022,9,26]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1301","DOI":"10.1016\/S0140-6736(20)32549-6","article-title":"Psoriasis","volume":"397","author":"Griffiths","year":"2021","journal-title":"Lancet"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"81","DOI":"10.1038\/s41419-022-04523-3","article-title":"Advances in the pathogenesis of psoriasis: From keratinocyte perspective","volume":"13","author":"Zhou","year":"2022","journal-title":"Cell Death Dis."},{"key":"ref_3","doi-asserted-by":"crossref","first-page":"983","DOI":"10.1016\/S0140-6736(14)61909-7","article-title":"Psoriasis","volume":"386","author":"Boehncke","year":"2015","journal-title":"Lancet"},{"key":"ref_4","doi-asserted-by":"crossref","first-page":"205","DOI":"10.1111\/jdv.13854","article-title":"A systematic review of worldwide epidemiology of psoriasis","volume":"31","author":"Michalek","year":"2017","journal-title":"J.
