Atopic dermatitis (AD) is a chronic inflammatory skin disease that is not fully understood. Defects in skin barrier function and dysregulation of the Th2 immune response are thought to be pivotal in AD pathogenesis. In this study, we used keratinocytes and AD-like skin equivalent models using Th2 cytokines IL-4 and IL-13. The keratinocytes and AD-like skin model were used to investigate the effect of dipotassium glycyrrhizinate (KG), which is widely used as an anti-inflammatory agent for AD treatment. KG decreased AD-related gene expression in keratinocytes stimulated with Th2 cytokines. KG alleviated AD-like phenotypes and gene expression patterns and inhibited release of AD-related cytokines in the AD-like skin equivalent models. These findings indicate KG has potential effectiveness in AD treatment and AD-like skin equivalent models may be useful for understanding AD pathogenesis.

Atopic dermatitis (AD) is a chronic dermatological disorder characterized by intense pruritus and eczematous lesions. Repeated topical application of 2,4-dinitrofluorobenzene (DNFB) in NC/Nga mice produces AD-like clinical symptoms that closely resemble human AD. N-Acetyl-L-Alanine (L-NAA), a derivative of L-Alanine, has unknown biological and physiological effects on cutaneous tissue.

Background: Recent findings suggest skin microbiota is closely linked to the aggravation of atopic dermatitis (AD) and skin barrier dysfunction.
Methods: This prospective cross-sectional study included 52 children: 35 with AD flare (F) and non-flare (NF), and 17 without AD (non-AD). Microbes in the skin samples from the three groups were analyzed using 16S rRNA amplicon sequencing.

Protocatechuic aldehyde (PA) is an active compound of Salvia miltiorrhiza (Danshen), a traditional Chinese herb wildly used for inflammatory skin diseases therapy. STAT3 activation plays a pivotal role in multiple inflammatory cutaneous diseases. We previously reported that topical treatment with PA ameliorated psoriasis-like skin inflammation, a typical Th1-mediated inflammatory skin disease, by inactivating STAT3.

Atopic dermatitis-like graft-versus-host disease (AD-like GVHD) is a rare but challenging complication following hematopoietic stem cell transplantation (HSCT), mimicking features of atopic dermatitis (AD) and often requiring prolonged immunosuppression. We report the case of a 14-year-old girl with a history of mild AD and post-HSCT GVHD involving skin and the gastrointestinal tract, presenting with severe pruritus, extensive eczema, and significant impact on quality of life. Standard treatment with corticosteroids and immunosuppressants yielded suboptimal results and notable side effects, including growth retardation.

Atopic dermatitis (AD) is a common chronic inflammatory skin disorder characterized by immune dysregulation and skin barrier impairment. This study evaluated the anti-inflammatory and immunomodulatory effects of extract in a 2,4-dinitrochlorobenzene (DNCB)-induced AD mouse model using SKH-1 hairless mice. Topical application of extract for four weeks significantly alleviated AD-like symptoms by reducing epidermal thickness, mast cell infiltration, and overall skin inflammation.
