Article Abstract
Background: Organophosphate pesticides (OPPs) are widely used environmental chemicals with potential health impacts, but their relationship with atopic dermatitis (AD) remains unclear.
Methods: Using data from the National Health and Nutrition Examination Survey (NHANES) 1999-2007, we investigated associations between urinary OPP metabolites and AD in 4,258 adults. Six dialkyl phosphate (DAP) metabolites were measured, and weighted quantile sum (WQS) regression was used to assess mixture effects.
Results: Both DMP (odds ratio [OR] = 1.17, 95% confidence interval [CI]: 1.05-1.31) and DMDTP (OR = 2.23, 95%CI: 1.08-4.60) showed significant positive associations with AD in fully adjusted models. WQS regression revealed significant associations between mixed OPP exposure and AD (OR = 1.25, 95%CI: 1.04-1.50), with DMP contributing most (45.8%) to the mixture effect. Stratified analyses indicated stronger associations in males, younger adults (<60 years), and smokers.
Conclusion: Our findings suggest that OPP exposure, particularly DMP, may be associated with increased AD risk in adults. These results provide new insights into environmental risk factors for AD.

Allergic diseases, characterized by complex pathological mechanisms involving immune dysregulation and chronic inflammation, impose a substantial burden on global health. The Hippo signaling pathway, a highly conserved regulator of cell proliferation, apoptosis, immune homeostasis, and tissue repair, has recently emerged as a pivotal player in allergic disease pathogenesis. This review synthesizes current knowledge on the core components and physiological functions of the Hippo pathway, elucidates its mechanistic roles in major allergic disorders-including allergic asthma, allergic rhinitis, atopic dermatitis, and food allergies-and evaluates the therapeutic potential of targeting this pathway.

The epidermal immune microenvironment is a multifaceted system in which the interplay between the skin microbiome and antimicrobial peptides plays a pivotal role in sustaining skin homeostasis and preventing dysbiosis. Disruption of these interactions can lead to inflammatory skin conditions such as atopic dermatitis. This review aims to explore the complex mechanisms by which antimicrobial peptides and the skin microbiome communicate within the epidermal immune microenvironment, emphasizing causal dynamics and the dual role of antimicrobial peptides.

Atopic dermatitis (AD) is a chronic inflammatory skin disease characterized by eczematous lesions, intense itching, and compromised skin barrier function. Despite the advent of new therapeutics, many individuals still face insufficient disease control, high costs, and relapse. Protease-activated receptor 2 (PAR-2), overexpressed in AD lesions, plays a central role in promoting inflammation, itch, and alterations in epidermal homeostasis.
