Abstract<\/strong>
Psoriasis is a chronic inflammatory skin disease characterized by dysregulated immune responses and epidermal hyperproliferation, in which cytokine networks involving IL-17 and IL-23 play a central pathogenic role [1]. Keratinocytes actively contribute to this process by producing pro-inflammatory mediators and sustaining local immune activation. Despite advances in systemic therapies, effective topical strategies targeting these pathways remain limited due to the impaired barrier function of psoriatic skin [2]. 20-Hydroxyecdysone (20-HE), a natural phytoecdysteroid, exhibits anti-inflammatory, antioxidant, and cytoprotective properties, but has limited skin penetration and bioavailability. Therefore, lipid-based nanocarrier delivery systems have been developed to enhance dermal delivery and improve the biological activity of active compounds [3]. In this study, lipid-based nanocarrier formulations containing 20-HE were developed and characterized, and their biological activity was evaluated in human epidermal keratinocytes (HEKs) and psoriasis-derived keratinocytes (PHEKs). Cells were treated with the respective nanoformulations for 48 hours. Cytokine levels, including IL-17A and IL-23, were quantified using a Western blot assay. All tested nanoformulations of 20-HE modulated inflammatory responses in keratinocytes, with differential effects depending on the carrier type. In conclusion, nanoformulations containing 20-HE exhibit distinct anti-inflammatory profiles in psoriatic keratinocytes. Modulation of IL-17\/IL-23-associated signaling highlights the potential of these nanocarrier systems to become promising candidates for topical psoriasis therapy.<\/td><\/tr>
