KM110329 is four traditional herbal medicine mixtures with anti-inflammatory properties. Atopic dermatitis (AD) is an inflammatory skin disease associated with enhanced T-helper2 (Th2) lymphocyte response to allergens that results in elevated serum eosinophil and Immunoglobulin E (IgE) levels and leukocyte infiltration in atopic skin sites. In this study, we investigated the effect of topical application of KM110329 ethanol extract on the ovalbumin (OVA) or 2,4-dinitrochlorobenzene- (DNCB-) induced AD mouse models. For that purpose, we observed the effects of KM110329 on blood eosinophils, skin mast cells, production of serum IgE, and expression of cytokine mRNA in the atopic dermatitis skin lesions of OVA allergen- or DNCB-treated BALB/c mice. KM110329 significantly reduced blood eosinophils cell numbers in OVA or DNCB-treated BALB/c mice. Histological analyses demonstrated decreased mast cell count as well as dermal infiltration by inflammatory cells. In the skin lesions, mRNA expression of interleukine (IL)-4, IL-13, and IL-17 was inhibited by KM110329. KM110329 also suppressed the production of serum IgE level in both the OVA- and DNCB-induced atopic dermatitis model. Taken together, our results showed that topical application of KM110329 extracts exerts beneficial effects in AD symptoms, suggesting that KM110329 might be a useful candidate for the treatment of AD.

Atopic dermatitis (AD) is a chronic inflammatory skin disease caused mainly by immune dysregulation. This study explored the anti-inflammatory and immunomodulatory effects of the Centella asiatica ethanol extract (CA) on an AD-like dermal disorder. Treatment with CA inhibited the expression of interleukin-6 (IL-6) and tumor necrosis factor-α (TNF-α) in a dose-dependent manner in inflammatory stimulated HaCaT cells by interferon-γ (IFN-γ) and TNF-α-triggered inflammation. Eight-week-old BALB/c mice treated with 2,4-dinitrochlorobenzene (DNCB) were used as a mouse model of AD. In AD induce model, we had two types treatment of CA; skin local administration (80 µg/cm2, AD+CA-80) and oral administration (200 mg/kg/d, AD+CA-200). Interestingly, the CA-treated groups exhibited considerably decreased mast cell infiltration in the ear tissue. In addition, the expression of IL-6 in mast cells, as well as the expression of various pathogenic cytokines, such as TNF-α, IL-4, IL-5, IL-6, IL-10, IL-17, iNOS, COX-2, and CXCL9, was reduced in both AD+CA-80 and AD+CA-200 groups. Collectively, our data demonstrate the pharmacological role and signaling mechanism of CA in the regulation of allergic inflammation of the skin, which supports our hypothesis that CA could potentially be developed as a therapeutic agent for AD.

Atopic dermatitis (AD) is a chronic inflammatory disease. Combretum quadrangulare (C. quadrangulare) is used as a traditional medicine to improve various pathologies in Southeast Asia. In this study, we investigated the effects of C. quadrangulare ethanol extract (CQ) on 1-chloro-2,4-dinitrobenzene (DNCB)-induced AD like skin lesions in BALB/c mice. After administration with CQ (100, 200, and 400 mg/kg) for 6 weeks, AD symptoms, protein expression, immunoglobulin E (IgE), thymus and activation-regulated chemokine (TARC), and ceramidase level were measured in skin lesions of DNCB-induced BALB/c mice. CQ group improved the dermatitis score, skin pH, transepidermal water loss (TEWL), and skin hydration. Furthermore, histological analysis revealed that CQ attenuated the increased epidermal thickness and infiltration of mast cells caused by DNCB. CQ also increased the expression of filaggrin, and reduced the expression of ceramidase, serum IgE level, and the number of eosinophils. CQ effectively inhibited cytokines and chemokines such as interleukin (IL)-6, IL-13, TARC, and thymic stromal lymphopoietin (TSLP) at the mRNA levels, as well as the activation of mitogen-activated protein kinase (MAPK), including extracellular signal-regulated kinase (ERK), c-jun N-terminal kinase (JNK), and p38 in the skin lesions. Taken together, these findings demonstrate that CQ may be an effective treatment of AD-like skin lesions by inhibiting the expression of inflammatory mediators via the MAPK signaling pathways.
