Chrysanthemum indicum L. (CIL) is widely used as an anti-inflammatory agent in Asia and our preliminary study revealed that CIL reduced interleukin (IL)-4 and IL-13 in 2,4-dinitrochlorobenzene (DNCB)-treated HaCaT cells, a human keratinocyte cell line. We investigated the atopic dermatitis (AD) effect of topically applied CIL in mice with AD-like symptoms. After topical application of 1,3-butylen glycol (control), CIL-Low (5%), CIL-High (30%), or 0.1% hydrocortisone (HC) on the AD-like skin lesions in DNCB-treated NC/Nga mice for 5 weeks, the ear thickness, mast cell infiltration, and serum immunoglobulin E (IgE), IgG1, IL-4 and interferon (IFN)-γ were measured. The gene expressions of IL-4, IL-13, and IFN-γ in the dorsal skin were assayed. CIL treatment dosedependently reduced severity of clinical symptoms of dorsal skin, ear thickness, and the number of mast cells and eosinophils. CIL-High significantly decreased serum IgE, IgG1, IL-4, and IFN-γ levels and reduced mRNA levels of IFN-γ, IL-4, and IL-13 in dorsal skin lesion. The improvement by CIL-High was similar to HC, but without its adverse effects such as skin atrophy maceration, and secondary infection. In conclusion, CIL may be an effective alternative substance for the management of AD.

    • "Conversely, among the eight studies that measured interferon- (IFN-)γ, topical herbal application resulted in increased IFN-γ levels in two studies, decreased levels in five studies, and no induced changes in one study. Interestingly, in one study [10], Chrysanthemum indicum L. decreased both Th1 (IFN-γ) and Th2 cytokines (IL-4 and IL-13); however, the ratio of Th1 to Th2 cytokines was increased by herbal application.

    ABSTRACT: Herbs are widely used in the treatment of atopic dermatitis (AD) in Eastern Asian countries, and certain herbs regarded have anti-inflammatory properties that can help with AD. With the goal of developing a topical herbal agent for AD, we conducted a systematic review of in vivo studies of AD-like skin models for screening potential herbs. Searches were conducted from PubMed and EMBASE. After all, 22 studies were included for this review. We judged most of the domains of all studies to be at unclear risk of bias. Among 22 included studies, 21 herbs have been reported to reduce AD-like skin lesions in mouse models by suppressing Th2 cell response. Our findings may offer potential herbs for the topical application treatment of AD.

    ABSTRACT: Vaccinium uliginosum L. (VU) possesses various biological properties, such as antioxidant and protective effects against VU-induced skin photoaging. The purpose of this study is to evaluate the effects of oral administration of a mixture of polyphenols and anthocyanins derived from VU on 2,4-dinitrochlorobenzene- (DNCB-) induced atopic dermatitis (AD) in NC/Nga mice. We assessed anti-AD effects in NC/Nga murine model for a period of 9 weeks. Oral administration of the mixture significantly alleviated the AD-like skin symptoms and clinical signs including ear thickness and scratching behaviors. Orally administrated mixture reduced the level of IgE and IgG1, whereas it increased the level of IgG2a in a dose-dependent manner. The calculated IgG1/IgG2a ratio for each mouse revealed that the mixture derived from VU also significantly reduced the Th2/Th1 ratio, IL-4 and IL-13 (as Th2 cytokines), IFN-γ, and IL-12 (as a Th1 cytokine) in spleens. In addition, it significantly decreased gene expression, such as IL-4, IL-5, CCR3, eotaxin-1, IL- 12, IFN-γ, MCP-1, and IL-17, in AD-like lesions and suppressed Th17. Histological analyses revealed that the epidermis thickness and number of inflammatory cells were significantly reduced. In conclusion, oral administration of the mixture in the DNCB-induced AD is confirmed to improve AD disease in mice.

    ABSTRACT: Pleurotus eryngii is a nutritional and medicinal food rich in polysaccharides that enhance the host immune system as a response to various diseases. The present study investigated the effects of Pleurotus eryngii extracts (PEE) on the progress of atopic dermatitis (AD)-like skin lesions in NC/Nga mice induced by 2,4-dinitrochlorobenzene (DNCB). We evaluated skin dermatitis severity, ear thickness, histopathological examination, and cytokines level in DNCB-applied mice treated with PEE. Continuous treatment of PEE inhibited the development of the AD-like skin lesions. PEE suppressed DNCB-induced dermatitis severity, serum level of IgE and thymus and activation-regulated chemokine (TARC), and mRNA expression of TNF-α, INF-γ, IL-4, IL-5, and IL-13 in mice. In addition, PEE reduced thickness of the dermis and dermal infiltration of inflammatory cells and mast cells in histopathological examination. These results indicate that PEE inhibits allergic contact dermatitis through the modulating of T helper (Th)1 and Th2 responses and diminishing the inflammatory cells and mast cells infiltration in the skin lesions in NC/Nga mice.
