Vanden Heuvel JP, Zhou S, Patel AB, Kamerow HN, Baran P, Ford JP. Preclinical Demonstration of a Novel Treatment with High Efficacy and No Detectable Toxicity for Inflammatory Skin Conditions including Psoriasis. BIOMED RESEARCH INTERNATIONAL 2023; 2023:4878774. [PMID: 37469991 PMCID: PMC10353900 DOI: 10.1155/2023/4878774] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 01/12/2023] [Revised: 06/01/2023] [Accepted: 06/03/2023] [Indexed: 07/21/2023]
Abstract
Although the management options for psoriasis have progressed with the use of systemic agents, there are few efficacious nonsteroidal topical therapies for patients with limited or lower grade disease. The effects of allopurinol (Allo) and glutathione (GSH) were examined in two different in vitro models for psoriasis. In the first model, human immortalized keratinocytes (HaCaT) were treated with M5 cocktail (IL-17A, IL-22, oncostatin M, IL-1α, and TNF-α) in four interventional groups (control, Allo, oxypurinol (Oxy), and methotrexate (MTX)). The number of live and dead cells was determined after treatment for 48 and 72 hrs. Allo decreased cell proliferation (total cells) without increasing cell death compared to both its xanthine oxidase inhibiting metabolite Oxy and a standard agent in clinical use, MTX. In the second model, a human psoriatic skin equivalent (PSE) culture system, cells were treated with vehicle control, Allo and GSH (as monotherapies and in combination), and vitamin D (VitD) for 2 and 6 days followed by histological analysis and altered gene expression. The combined exposure to Allo and GSH was equivalent to a standard antipsoriasis agent VitD in the inhibition of both proliferative and replicative markers. Histologic examination of the tissue at 6 days of exposure to VitD resulted in loss of the integrity of the squamous/epithelial continuity whereas tissue integrity was preserved with Allo and GSH exposure. The additional exposure of GSH to Allo reversed the increased thickness of the dermis layer caused by Allo exposure alone. Taken together, this data shows that topical Allo and GSH may have a synergistic effect with low toxicity and constitute a therapeutic advantage over current nonsteroidal therapies in the treatment of inflammatory skin conditions marked by increased cell proliferation such as psoriasis.

Abstract
Phusang warm pond or Phusang hot spring (Thailand) has a temperature of approximately 36–38 °C and may be suitable for bacterial growth. However, data on the microbiota and effectiveness of this water remain obscure. Therefore, this study aimed to evaluate the characteristics of Phusang hot spring water by clarifying the microorganisms and viral pathogens present. Cytotoxicity, irritation, liposome uptake, antimicrobial and anti-inflammatory effects were evaluated. The levels of trace elements such as sodium (Na), calcium (Ca), and strontium (Sr) were confirmed. Phusang hot spring water was nontoxic to L-929 cells and HDFa cells and was nonirritating to human phototypes I to IV at 48 h. The antimicrobial effects of Phusang hot spring water on S. aureus, S. epidermidis, B. subtilis and E. coli were not detected using the agar well diffusion assay. Phusang hot spring water decreased interleukin-6 (IL-6) expression at 24 h compared with (PBS) and untreated controls, as measured using semi qRT‒PCR and ELISA. Phusang hot spring water combined with curcumin-loaded liposomes exerted antiaging effects, suggesting their benefits for application in cosmetic products. The bacteriophage families Myoviridae, Siphoviridae and Podoviridae were detected, but not HPV or EBV. Trace elements such as Na and Ca were present. Therefore, the importance of this study is that Phusang hot spring water exerts anti-inflammatory effects via IL-6, is nontoxic and nonirritating, and might be used for balneotherapy or as a cosmetic ingredient under sterile conditions.

Abstract
BACKGROUND Thai herbal formulations have been used traditionally in Thailand for the treatment of psoriasis. However, there is still a lack of scientific data supporting the effects of Thai herbal formulations in psoriasis treatment. OBJECTIVES This study aimed to demonstrate the therapeutic effects of Thai herbal formulations for the treatment of erythrodermic psoriasis. MATERIALS AND METHODS All Thai herbal formulations (haematic tonic, lymphatic treatment, skin treatment) were obtained from a traditional Thai medicine doctor, Mr. Somporn Chanwanitsakul. The effects of Thai herbal formulations in a patient with erythrodermic psoriasis were assessed for four weeks. Primary outcome, psoriasis area and severity index (PASI) and secondary outcome, safety data and dermatology life quality index (DLQI) measurements were evaluated at baseline and four weeks. Then, in vitro biological activities (antioxidant, anti-microbial, cytotoxic effects, and anti-inflammatory) of Thai herbal formulations were determined to promote the therapeutic effects. RESULTS Thai herbal formulations were safe and effective in the treatment of erythrodermic psoriasis and had a modest positive impact on the DQLI of the patient. In addition, in vitro studies have shown that all Thai herbal formulations revealed remarkable anti-oxidant and anti-inflammatory potential to support their therapeutic activities. However, the Thai herbal formulations possessed weak intrinsic antibacterial activities against all tested bacterial strains (MIC and MBC E. coli, S. aureus, S. pyogenes, P. aeruginosa: > 256 µg/ml). CONCLUSION The findings indicated that successful treatment of erythrodermic psoriasis with Thai herbal formulations was involved in their anti-oxidant and anti-inflammatory activities. They could be considered as an alternative treatment for refractory erythrodermic psoriasis.

Abstract
Herpes simplex virus 1 (HSV-1) is a large double-stranded DNA virus that encodes at least 80 viral proteins, many of which are involved in the virus-host interaction and are beneficial to the viral survival and reproduction. However, the biological functions of some HSV-1-encoded proteins are not fully understood. Nuclear factor κB (NF-κB) activation is the major antiviral innate response, which can be triggered by various signals induced by cellular receptors from different pathways. Here, we demonstrated that HSV-1 UL2 protein could antagonize the tumor necrosis factor α (TNF-α)-mediated NF-κB activation. Co-immunoprecipitation assays showed that UL2 could interact with the NF-κB subunits p65 and p50, which also revealed the region of amino acids 9 to 17 of UL2 could suppress the NF-κB activation and interact with p65 and p50, and UL2 bound to the immunoglobulin-like plexin transcription factor functional domain of p65. However, UL2 did not affect the formation of p65/p50 dimerization and their nuclear localizations. Yet, UL2 was demonstrated to inhibit the NF-κB activity by attenuating TNF-α-induced p65 phosphorylation at Ser536 and therefore decreasing the expression of downstream inflammatory chemokine interleukin 8. Taken together, the attenuation of NF-κB activation by UL2 may contribute to the escape of host's antiviral innate immunity for HSV-1 during its infection.

PHYTOMEDICINE : INTERNATIONAL JOURNAL OF PHYTOTHERAPY AND PHYTOPHARMACOLOGY 2018; 47:48-57. [PMID: 30166108 DOI: 10.1016/j.phymed.2018.04.051] [Citation(s) in RCA: 17] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 11/29/2017] [Revised: 03/12/2018] [Accepted: 04/29/2018] [Indexed: 06/08/2023]
Abstract
BACKGROUND The traditional herbal formula, Dang-Gui-Liu-Huang Tang (DGLHT) has been previously shown to inhibit T lymphocyte proliferation and suppress dendritic cell function. Hypothesis/Purpose: To assess the therapeutic value of DGLHT for the treatment of psoriasis, a Th1 and/or Th17 cell-mediated inflammatory skin disease, and to investigate the underlying molecular mechanisms. METHODS An in vivo mouse model of imiquimod (IMQ)-induced psoriasis-like inflammation was used to investigate the effect of DGLHT. The anti-inflammatory effects of an ethanolic extract of DGLHT (DGLHT-E) and the mechanism responsible were examined in an in vitro model using IL-1α, IL-17A, IL-22, oncostatin M, plus TNF-α (M5) stimulated HaCaT cells. The anti-proliferative effect of DGLHT-E was examined by analyzing the expression levels of K16, K17 and Ki67 in IL-22 stimulated HaCaT cells. RESULTS Topical application of 1% DGLHT-E significantly reduced psoriasis-like symptoms including scaling and epidermal hyperplasia in IMQ-treated mice. Immunohistochemical studies showed that DGLHT-E exerted potent anti-inflammatory effects by inhibiting IL-22 production in local skin lesions. DGLHT-E also attenuated the productions of CXCL10 and CCL20 in M5-stimulated HaCaT cells by suppressing the ERK1/2, JNK and STAT3 signaling pathways. Furthermore, berberine hydrochloride, a primary constituent of DGLHT-E inhibited the expressions of the proliferation markers K16 and K17 in IL-22 stimulated HaCaT cells. CONCLUSION These results suggested that DGLHT-E offers a possible treatment for psoriasis, and that berberine hydrochloride might be a useful component of ointment-based treatments for psoriatic lesions.

Abstract
Psoriasis is a common immune-mediated chronic inflammatory skin disease characterized by thick and erythema raised plaques with adherent silvery scales. T-cells are activated via the IL-23/Th17 axis which is involved in psoriasis pathogenesis. Conventional treatments of psoriasis have adverse events that influence patients' adherence. Wannachawee Recipe (WCR) is Thai traditional medicine that is known to be effective for psoriasis patients; however, preclinical evidence is still lacking. This study investigated the therapeutic potential of WCR on antiproliferant activity using imiquimod- (IMQ-) induced psoriasis-like dermatitis in a mouse model. Psoriasis-like dermatitis was induced on the shaved dorsal skin and right ear pinna of BALB/c mice by topical application of IMQ for 15 consecutive days after which WCR was administered to the mice by oral gavage for 10 days. Phenotypical observations, histopathological examinations, and ELISA of skin and blood samples were conducted. WCR significantly ameliorated development of IMQ-induced psoriasis-like dermatitis and reduced levels of Th17 cytokines (IL-17A, IL-22, and IL-23) in both serum and dorsal skin. Histopathological findings showed a decrease in epidermal thickness and inflammatory T-cell infiltration in the WCR-treated groups. The WCR has pharmacological actions which regulate Th17 related cytokines suggesting that it is a potential alternative therapeutic strategy for psoriasis.
