Curr Pharm Des 2023; 29:2345-2353. [PMID: 37594098 DOI: 10.2174/1381612829666230818145709] [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: 11/14/2022] [Revised: 05/25/2023] [Accepted: 06/14/2023] [Indexed: 08/19/2023]
Abstract
INTRODUCTION The present study evaluates expression by activated CD4+ T helper1 (Th1) and T helper 2 (Th2) T lymphocytes of pro-inflammatory cytokines and cytoprotective heat shock proteins (HSPs) in peripheral blood of atopic dermatitis (AD) patients. METHODS This research represents preliminary work by the authors to identify correlates between critical immune parameters with the potential to serve as guidelines for the development of pharmacological strategies for altering these factors to promote the restoration of healthy immune profiles in persons afflicted with major atopic diseases. The major experimental strategy used in this research assessed immune activation by peripheral blood mononuclear cells (PBMC) from 21 AD patients and 12 age- and gender-matched healthy control subjects cultured with phorbol myristate acetate (PMA) and ionomycin (PMA/I), which are mutagenic immune activators, to induce expression of pro-inflammatory biomarkers in CD4+ T cells differentiated to express Th1 or Th2 cytokines and heme oxygenase-1 (HO-1) intracellularly (i). Evaluations were performed using an FC500 Beckman-Coulter flow cytometer. Elevated CD4+ T cell expression of cytokines, interleukin-4 (iIL-4), interleukin- 5 (iIL-5), interleukin-10 (iIL-10), interferon-gamma (iIFN-g), tumor necrosis factor-alpha (iTNF-α), were observed. RESULTS Additionally, the heat shock proteins (HSP) iHO-1 and iHSP-70 were evaluated in cells from the blood of AD patients versus the control subjects. The present study demonstrated an elevated expression of both Th1 and Th2-associated cytokines in CD4+ T cells of AD patients, with a significant direct correlation between Th1 and Th2 cell populations, thus yielding insight into the immune features of the AD-associated systemic inflammatory profile. CONCLUSION Finally, the observed increased iHO-1 and iHSP-70 expressions likely represent adaptive physiologic countermeasures to AD-associated inflammatory tissue damage, suggesting that HSP inducers are promising candidates for the management of atopic disorders.

Abstract
The Kelch-like erythroid cell-derived protein with cap‘n’collar homology-associated protein 1 (KEAP1)-nuclear factor erythroid-2-related factor 2 (NRF2) system, a thiol-based sensor-effector apparatus, exerts antioxidative and anti-inflammatory effects and maintains skin homeostasis. Thus, NRF2 activation appears to be a promising treatment option for various skin diseases. However, NRF2-mediated defense responses may deteriorate skin inflammation in a context-dependent manner. Atopic dermatitis (AD) and psoriasis are two common chronic inflammatory skin diseases caused by a defective skin barrier, dysregulated immune responses, genetic predispositions, and environmental factors. This review focuses on the role of the KEAP1-NRF2 system in the pathophysiology of AD and psoriasis and the therapeutic approaches that utilize this system.

Abstract
Nuclear factor erythroid-derived 2-like 2 (Nrf2) is a stress-activated transcription factor that is highly responsive to oxidative stress and electrophilic stimuli. Upon activation, Nrf2 upregulates a battery of cytoprotective genes meant to prevent cell death or damage. In many models of inflammation, Nrf2 protects against the immune response and decreases injury, including in the context of asthma and allergy. However, in some models of asthma and allergy, Nrf2 either does not play a role or can even exacerbate inflammation. In general, the reasons behind these discrepancies are not clear and the mechanisms by which Nrf2 modulates immune response are largely uncharacterized. The aim of this review is to highlight current literature assessing the role of Nrf2 in allergy and asthma to understand Nrf2 as a potential therapeutic target. SIGNIFICANCE STATEMENT: Nuclear factor erythroid-derived 2-like 2 (Nrf2) is an important immune mediator that modulates numerous immune cell types in various inflammatory diseases, including allergy and asthma. There is considerable interest in Nrf2 as a drug target in inflammation, which is complicated by the complex nature of Nrf2 in the immune system. This review focuses on the role of Nrf2 in asthma and allergy, including in regulating immune cell function and in detoxifying xenobiotics that exacerbate these diseases.

Abstract
Atopic dermatitis (AD) is a complex inflammatory skin disorder, characterized by a complicated pathophysiology and a wide range of clinical phenotypes. Roxatidine acetate chloride (RXA) is a precursor of Roxatidine and a histamine H2 receptor antagonist, used for the treatment of gastric ulcers. In this study, we aimed to examine whether RXA had anti-AD effects and determine the underlying molecular mechanism of RXA. The anti-AD effects were examined in Dermatophagoides farinae body (Dfb)-induced AD mouse model, tumor necrosis factor (TNF)-α/interferon (IFN)-γ-stimulated HaCaT keratinocytes, and human skin equivalent model using ELISA, histological analysis, immunohistochemistry, Western blot, and immunofluorescence. Results showed that RXA treatment significantly alleviated Dfb-induced AD skin symptoms and clinical severity in mice by decreasing the levels of immunoglobulin E, histamine, and inflammatory cytokines. RXA effectively inhibited the expression of adhesive molecules and recovered the filaggrin expression in Dfb-induced AD skin lesions and TNF-α/IFN-γ-stimulated HaCaT keratinocytes. Additionally, RXA significantly upregulated the expression of aryl hydrocarbon receptor and sirtuin1. The anti-AD effects of RXA were associated with suppressed nuclear factor kappa cascade. Overall, our results suggest that RXA may be a potential anti-AD candidate owing to its inhibitory effect against skin inflammation and protection of the skin barrier function in AD.

PHYTOMEDICINE : INTERNATIONAL JOURNAL OF PHYTOTHERAPY AND PHYTOPHARMACOLOGY 2021; 91:153708. [PMID: 34455178 DOI: 10.1016/j.phymed.2021.153708] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 03/18/2021] [Revised: 08/09/2021] [Accepted: 08/10/2021] [Indexed: 06/13/2023]
Abstract
PURPOSE Rosa davurica Pall., is mainly distributed in Korea, Japan, northeastern China, southeastern Siberia, and eastern Asia. It has been extensively used to treat various kinds of diseases by reason of the significant antioxidant, antiviral and anti-inflammatory activities. However, the pharmacological mechanism of Rosa davurica Pall. in atopic dermatitis (AD) is still ill defined and poorly understood. This study was to examine the anti-inflammatory effects and its mechanism on AD of Rosa davurica Pall. leaves (RDL). METHODS To evaluate the therapeutic potential of RDL against AD, we have investigated the effects of RDL on the inflammatory reactions and the productions of inflammatory chemokines and cytokines that were induced by tumor necrosis factor-α (TNF-α)/interferon-γ (IFN-γ) in HaCaT cells. Futhermore, we examined the effects of RDL on the signaling pathways of mitogen-activated protein kinase (MAPK) and nuclear factor-kappa B (NF-κB). For the in-vivo studies, RDL extract was topically applied to the dinitrochlorobenzene (DNCB)-induced AD mice, then its therapeutic effect was evaluated physiologically and morphologically. RESULTS After the stimulation of HaCaT cells with TNF-α/IFN-γ, RDL considerably reduced the release of inflammatory mediators such as nitric oxide (NO), PEG2 and other cytokines. RDL also reduced the phosphorylations of MAPK and NF-κB in TNF-α/IFN-γ-stimulated HaCaT cells. In vivo topical application of RDL to DNCB-induced AD mice significantly reduced the dorsal skin and ear thickness, clinical dermatitis severity, and mast cells. Treatment with RDL also markedly decreased the levels of serum IgE, IL-6 and the number of WBCs in the blood. CONCLUSION Our studies indicate that RDL inhibits the AD-like skin lesions by modulating skin inflammation. Consequently, these results suggest that RDL may be served as a possible alternative therapeutic treatment for skin disorder such as AD.

Abstract
The short release half-life of carbon monoxide (CO) is a major obstacle to the effective therapeutic use of carbon monoxide-releasing molecule-2 (CORM-2). The potential of CORM-2-entrapped ultradeformable liposomes (CORM-2-UDLs) to enhance the release half-life of CO and alleviate skin inflammation was investigated in the present study. CORM-2-UDLs were prepared by using soy phosphatidylcholine to form lipid bilayers and Tween 80 as an edge activator. The deformability of CORM-2-UDLs was measured and compared with that of conventional liposomes by passing formulations through a filter device at a constant pressure. The release profile of CO from CORM-2-UDLs was evaluated by myoglobin assay. In vitro and in vivo anti-inflammatory effects of CORM-2-UDLs were assessed in lipopolysaccharide-stimulated macrophages and TPA-induced ear edema model, respectively. The deformability of the optimized CORM-2-UDLs was 2.3 times higher than conventional liposomes. CORM-2-UDLs significantly prolonged the release half-life of CO from 30 s in a CORM-2 solution to 21.6 min. CORM-2-UDLs demonstrated in vitro anti-inflammatory activity by decreasing nitrite production and pro-inflammatory cytokine levels. Furthermore, CORM-2-UDLs successfully ameliorated skin inflammation by reducing ear edema, pathological scores, neutrophil accumulation, and inflammatory cytokines expression. The results demonstrate that CORM-2-UDLs could be used as promising therapeutics against acute skin inflammation.

Abstract
Chijabyukpi-tang (CBT) is an oriental herbal formula consisting of three herbs (Gardeniae Fructus (Gardenia jasminoides J.Ellis.), Phellodendri Cortex (Phellodendron amurense Rupr.), Glycyrrhizae Radix (Glycyrrhiza uralensis Fisch. ex DC.) at the ratio of 2: 2: 1. CBT has traditionally been used to treat eczema with inflammation in Northeast Asia. The components of CBT have been shown to have anti-inflammatory and anti-oxidant properties, but the exact role and mechanism of CBT on atopic dermatitis (AD) remain unclear. In this study, we investigated the anti-inflammatory effect and mechanism of CBT in the HaCaT human keratinocyte cell line and investigated the anti-atopic effect in mice models of atopic dermatitis-like skin lesions. In the tumor necrosis factor alpha (TNF)-α/interferon (IFN)-γ-stimulated HaCaT cells, CBT inhibited the production of pro-inflammatory cytokines and chemokines and elevated the nuclear translocation of NF-E2 p45 related factors 2 (Nrf2) and subsequent production of heme oxygenase-1 (HO-1). CBT improved the symptoms of atopic dermatitis-like lesions in 2,4-dinitrochlorobenzene (DNCB)-treated mice by suppressing the levels of serum immunoglobulin E (IgE), and various pro-inflammatory cytokines and chemokines. The improvement effect of CBT on atopic dermatitis-like lesions can be predicted to be due to increased Nrf2 and HO-1 gene expression. These results suggest that CBT is an herbal medicine with the potential for use as a therapeutic agent for inflammatory skin diseases such as atopic dermatitis.

Abstract
The skin is an important physiological barrier against external stimuli, such as ultraviolet radiation (UV), xenobiotics, and bacteria. Dermal inflammatory reactions are associated with various skin disorders, including chemical-induced irritation and atopic dermatitis. Modulation of skin inflammatory response is a therapeutic strategy for skin diseases. Here, we synthesized chrysin-derivatives and identified the most potent derivative of Compound 6 (CPD 6). We evaluated its anti-inflammatory effects in vitro cells of macrophages and keratinocytes, and in vivo dermatitis mouse models. In murine macrophages stimulated by lipopolysaccharide (LPS), CPD 6 significantly attenuated the release of inflammatory mediators such as nitric oxide (NO) (IC50 for NO inhibition: 3.613 μM) and other cytokines. In cultured human keratinocytes, CPD 6 significantly attenuated the release of inflammatory cytokines induced by the combination of IFN-γ and TNF-α, UV irradiation, or chemical irritant stimulation. CPD 6 inhibited NFκB and JAK2/STAT1 signaling pathways, and activated Nrf2/HO-1 signaling. In vivo relevancy of anti-inflammatory effects of CPD 6 was observed in acute and chronic skin inflammation models in mice. CPD 6 showed significant anti-inflammatory properties both in vitro cells and in vivo dermatitis animal models, mediated by the inhibition of the NFκB and JAK2-STAT1 pathways and activation of Nrf2/HO-1 signaling. We propose that the novel chrysin-derivative CPD 6 may be a potential therapeutic agent for skin inflammation.

Abstract
Acute and chronic inflammatory diseases are associated with excessive inflammation due to the accumulation of pro-inflammatory mediators and cytokines produced by macrophages. In the present study, we investigated the anti-inflammatory properties of neochlorogenic acid (nCGA) from Lonicera japonica on lipopolysaccharide (LPS)-activated inflammation in macrophages and participation of the AMPK/Nrf2 pathway. nCGA pretreatment significantly reduced the production of nitric oxide, prostaglandin E2, TNF-α, reactive oxygen species, IL-1β, and IL-6 by LPS-activated macrophages. Moreover, both transcript and protein levels of inducible nitric oxide synthase and cyclooxygenase-2 were reduced by nCGA in LPS-activated macrophages. nCGA inhibited NF-κB activation by attenuating IKKα/β and IκBα phosphorylation in LPS-stimulated macrophages. Moreover, nCGA attenuated LPS-elevated JAK-1, STAT-1, and MAPK phosphorylation. We further evaluated the possible role of nCGA in the induction of AMPK/Nrf2 signal pathways required for the protein expression of HO-1 and NQO-1. nCGA induced AMPK activation via phosphorylation of LKB1 and CaMKII and by the inhibitory phosphorylation of GSK3β. It stimulated the overexpression of Nrf2/ARE-regulated downstream proteins, such as NQO-1 and HO-1. Furthermore, the anti-inflammatory effects of nCGA were attenuated in macrophages subjected to siRNAs specific for HO-1, NQO-1, Nrf2, and AMPK. Accordingly, these results indicate that nCGA, as an AMPK/Nrf2 signal activator, prevents excessive macrophage-mediated responses associated with acute and chronic inflammatory disorders.

Nutrients 2017; 9:nu9121371. [PMID: 29258247 PMCID: PMC5748821 DOI: 10.3390/nu9121371] [Citation(s) in RCA: 48] [Impact Index Per Article: 6.9] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/15/2017] [Revised: 12/10/2017] [Accepted: 12/15/2017] [Indexed: 12/25/2022] Open
Abstract
The transcription factor NRF2 (nuclear factor-E2-related factor 2) orchestrates major cellular defense mechanisms including phase-II detoxification, inflammatory signaling, DNA repair, and antioxidant response. Recent studies strongly suggest a protective role of NRF2-mediated gene expression in the suppression of cutaneous photodamage induced by solar UV (ultraviolet) radiation. The apocarotenoid bixin, a Food and Drug Administration (FDA)-approved natural food colorant (referred to as ‘annatto’) originates from the seeds of the achiote tree native to tropical America, consumed by humans since ancient times. Use of achiote preparations for skin protection against environmental insult and for enhanced wound healing has long been documented. We have recently reported that (i) bixin is a potent canonical activator of the NRF2-dependent cytoprotective response in human skin keratinocytes; that (ii) systemic administration of bixin activates NRF2 with protective effects against solar UV-induced skin damage; and that (iii) bixin-induced suppression of photodamage is observable in Nrf2+/+ but not in Nrf2−/− SKH-1 mice confirming the NRF2-dependence of bixin-induced antioxidant and anti-inflammatory effects. In addition, bixin displays molecular activities as sacrificial antioxidant, excited state quencher, PPAR (peroxisome proliferator-activated receptor) α/γ agonist, and TLR (Toll-like receptor) 4/NFκB (nuclear factor kappa-light-chain-enhancer of activated B cells) antagonist, all of which might be relevant to the enhancement of skin barrier function and environmental stress protection. Potential skin photoprotection and photochemoprevention benefits provided by topical application or dietary consumption of this ethno-pharmacologically validated phytochemical originating from the Americas deserves further preclinical and clinical examination.

Topical application of Moringa oleifera leaf extract ameliorates experimentally induced atopic dermatitis by the regulation of Th1/Th2/Th17 balance. Biomed Pharmacother 2016; 84:870-877. [PMID: 27744247 DOI: 10.1016/j.biopha.2016.09.085] [Citation(s) in RCA: 28] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/11/2016] [Revised: 08/24/2016] [Indexed: 11/24/2022] Open
Abstract
BACKGROUND Moringa oleifera (M. oleifera) is widely cultivated in tropical and subtropical regions and has been used as a vegetable and in traditional medicine. In this study, the anti-atopic dermatitis activity of the ethanol extract of M. oleifera leaf was investigated in vitro and in vivo. METHODS For the in vitro study, HaCaT human keratinocytes were used for cytokines and MAPKinase assay. In the in vivo study, M. oleifera leaf ethanolic extract (MO) was topically applied to BALB/c mice with Dermatophagoides farinae extract (DFE; house dust mite extract)- and 2,4-dinitrochlorobenzene (DNCB)-induced atopic dermatitis (AD). RESULTS The expression of TNF-α, CCL17, IL-1β, IL-6 pro-inflammatory cytokine-related mRNA, and mitogen-activated protein kinases (MAPKs) in TNF-α/IFN-γ-induced HaCaT keratinocytes were reduced by MO. Epidermal and dermal ear thickness, mast cell infiltration, serum immunoglobulin levels, as well as gene expression of various cytokines in the ear tissue, lymph nodes, and splenocytes were improved by treatment with MO. In addition, MO reduced the expression of retinoic acid-related orphan receptor γT (RORγT), thymic stromal lymphopoietin (TSLP), and mannose receptor (CD206) mRNA in the ear tissue and improved cervical lymph node size. CONCLUSION The results of this study strongly suggest the beneficial effects of MO on AD via the regulation of inflammatory responses.
