Abstract
Introduction Psoriasis, a persistent skin condition caused by the disorder of the immune system, impacts approximately 1.25 million individuals globally. Nevertheless, the presence of adverse effects in conventional clinical drugs necessitates further exploration of novel medications or combination therapies to mitigate these reactions and enhance their effectiveness. Methods Hence, our intention here in this paper is to utilize the lipid nanoparticle delivery system for overcoming the volatility and hydrophobic properties of α-pinene, a naturally occurring compound renowned for its anti-inflammatory and antiviral effects, and further explore its potential pharmacological applications both in vitro and in vivo. Results The production of α-pinene lipid nanoparticles (APLNs) was achieved through the utilization of high pressure homogenization methods. APLNs was successfully fabricated with enhanced stability and water solubility. Meanwhile, the application of APLNs could drastically reduce the expression of lipopolysaccharide (LPS)-induced inflammation-related factors in THP-1 cells. Administration of APLNs to a mouse model of auricular swelling could effectively reduce redness and swelling in the auricles of mice as well. Furthermore, APLNs were also found to alleviate skin damage in mice with Imiquimod (IMQ)-induced psoriasis model, as well as decrease the levels of psoriasis-related protein nuclear factor kappa-B (NF-κB) and interleukin-17 (IL-17), interleukin-23 (IL-23), and other inflammation-related cytokines. More importantly, utilization of APLNs successfully mitigated the systemic inflammatory reactions in mice, resulting in the reduction of spleen-to-body ratio (wt%) and of inflammatory cytokines' expression in the serum. Discussion Overall, our results suggest that with the help of lipid nanoparticle encapsulation, APLNs possess a better pharmacological effect in anti-inflammation and could potentially serve as an anti-psoriasis drug.

[PMID: 39273201 PMCID: PMC11395139 DOI: 10.3390/ijms25179254] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/25/2024] [Revised: 08/22/2024] [Accepted: 08/25/2024] [Indexed: 09/15/2024] Open
Abstract
Psoriasis is a chronic inflammatory skin disorder characterized by keratinocyte hyperproliferation, inflammation, and aberrant differentiation. Imiquimod-induced psoriasis in rodent models has been widely used to study the pathogenesis of the disease and evaluate potential therapeutic interventions. In this study, we investigated the efficacy of two commonly used treatments, Clobetasol and Tacrolimus, in ameliorating psoriatic symptoms in an Imiquimod-induced psoriasis Wistar rat model. Interestingly, rat models are poorly evaluated in the literature despite rats displaying several advantages in evaluating pharmacological substances. Psoriasis-like skin lesions were induced by topical application of Imiquimod cream on shaved dorsal skin for seven consecutive days. Following induction, rats in the treatment groups received either a Clobetasol or Tacrolimus ointment once daily for one week, while the control group did not receive any application. Disease severity was assessed using clinical scoring, histological examination, and measurement of proinflammatory cytokine levels. Both Clobetasol and Tacrolimus treatments significantly reduced psoriatic lesion severity compared to the control group. Clinical scoring revealed a decrease in erythema, scaling, transepidermal water loss, and thickness of skin lesions in both treatment groups with a more marked effect with Clobetasol. Histological analysis demonstrated reduced epidermal hyperplasia in treated animals compared to controls. Furthermore, Clobetasol led to a significant reduction in the expression levels of the interleukin-17 (IL-17a and IL-17f) proinflammatory cytokines in lesioned skin. Overall, our findings demonstrated the therapeutic efficacy of both Clobetasol and, in a modest manner, Tacrolimus in attenuating Imiquimod-induced psoriasis-like symptoms in a rat model. These results support the clinical use of these agents in the management of psoriasis and mitigating psoriatic inflammation. They also provide insights into the use of rats as a relevant species for the Imiquimod-induced psoriasis model.

Artemisia monosperma essential oil nanoformulations alleviate imiquimod-induced psoriasis-like dermatitis in mice. Int Immunopharmacol 2024; 139:112733. [PMID: 39043105 DOI: 10.1016/j.intimp.2024.112733] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/22/2024] [Revised: 07/16/2024] [Accepted: 07/18/2024] [Indexed: 07/25/2024]
Abstract
Psoriasis is an inflammatory immune-mediated skin disease that affects nearly 2-3 % of the global population. The current study aimed to develop safe and efficient anti-psoriatic nanoformulations from Artemisia monosperma essential oil (EO). EO was extracted using hydrodistillation (HD), microwave-assisted hydrodistillation (MAHD), and head-space solid-phase microextraction (HS-SPME), as well as GC/ MS was used for its analysis. EO nanoemulsion (NE) was prepared using the phase inversion method, while the biodegradable polymeric film (BF) was prepared using the solvent casting technique. A.monosperma EO contains a high percentage of non-oxygenated compounds, being 90.45 (HD), 82.62 (MADH), and 95.17 (HS-SPME). Acenaphthene represents the major aromatic hydrocarbon in HD (39.14 %) and MADH (48.60 %), while sabinene as monoterpene hydrocarbon (44.2 %) is the primary compound in the case of HS-SPME. The anti-psoriatic Effect of NE and BF on the successful delivery of A.monosperma EO was studied using the imiquimod (IMQ)-induced psoriatic model in mice. Five groups (n = 6 mice) were classified into control group, IMQ group, IMQ+standard group, IMQ+NE group, and IMQ+BF group. NE and BF significantly alleviated the psoriatic skin lesions and decreased the psoriasis area severity index, Baker's score, and spleen index. Also, they reduced the expression of Ki67 and attenuated the levels of tumor necrosis factor-alpha, interleukin 6, and interleukin 17. Additionally, NE and NF were able to downregulate the NF-κB and GSK-3β signaling pathways. Despite the healing properties of BF, NE showed a more prominent effect on treating the psoriatic model, which could be referred to as its high skin penetration ability and absorption. These results potentially contribute to documenting experimental and theoretical evidence for the clinical uses of A.monosperma EO nanoformulations for treating psoriasis.

Targeting upregulation of the immunosuppressive activity of MDSCs with indirubin as a novel strategy to alleviate psoriasis. Int Immunopharmacol 2023; 123:110710. [PMID: 37531829 DOI: 10.1016/j.intimp.2023.110710] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/28/2023] [Revised: 07/19/2023] [Accepted: 07/23/2023] [Indexed: 08/04/2023]
Abstract
BACKGROUND Psoriasis is a chronic and incurable skin disorder that causes inflammation. There is an urgent clinical need for new treatments. We identified the natural compound indirubin as a potential potent agent for the treatment of psoriasis, but it's therapeutic effect and underlying mechanisms were not well understood. METHODS Peripheral blood and skin tissues from psoriasis patients and healthy individuals were collected. Bioinformatics analysis was performed to investigate LAT1 expression and associated signal pathways in psoriasis skin lesions. A mouse model of psoriasis was established. Indirubin was administered separately or in combination with MDSCs depletion or adoptively transferred MDSCs. JPH203, rapamycin, siRNA, and NV5138 were further used to investigate the potential mechanism by which indirubin regulates MDSCs. RESULTS Psoriasis patients had increased numbers of MDSCs in their blood and skin lesions, with high expression of Lat1. The upregulation of LAT1 expression and the arginine synthesis pathway was observed in psoriasis skin lesions. The number of MDSCs was increased, while their inhibitory effect on psoriatic T cells was decreased. Indirubin decreased Lat1 expression on the surface of MDSCs, inhibited mTOR pathway activation, upregulated Arg1 expression in MDSCs, and enhanced the immunosuppressive activity of MDSCs while inhibiting CD4+CCR6+ T cells. CONCLUSION This study demonstrates indirubin's pharmacological and therapeutic effects, providing a basis for future clinical application in treating psoriasis.

Abstract
Psoriasis is a long-lasting and recurrent autoimmune disease which is incurable so far. Dead Sea water (DSW) therapy is an effective approach to help control the symptoms of psoriasis due to the abundant mineral ions in DSW, which inspired the material formulation in this study. Rubidium-Sodium alginate/Polyacrylamide hydrogels (Rb-SA/PAAm gels) composed of sodium alginate and polyacrylamide interpenetrating network structure with different concentrations of rubidium and certain magnesium and zinc content were prepared for the treatment of psoriasis. The obtained results suggest the good mechanical properties of the Rb-SA/PAAm gels including toughness and swelling performance. In terms of in vitro tests, the Rb-SA/PAAm gels not only show nontoxicity to human keratinocyte cell line (Hacats) but also inhibits the activity against inflammatory NF-κβ signaling pathway. Meanwhile, they can release Rb+ which enable the Rb-SA/PAAm gels have better antibacterial ability to Streptococcus and Escherichia coli. The results obtained from in vivo tests indicate that these hydrogels could alleviate the symptoms of psoriasis caused by Imiquimod (IMQ) in mice by reducing the inflammatory factor in STAT3 pathway and therefore reduce the immune stimulation of the spleen. In conclusion, the 100Rb-SA/PAAm gel has demonstrated great potential to be a topical wettable dressing for psoriasis treatment.
