In a population based study of 68 individuals with atopic dermatitis and 94 control individuals it was not possible to demonstrateany significant associations between the disease and gene frequencies of HLA-ABC, ABO, MN, Rhesus, Kell, Duffy, Hp, Gc, Gm, Km/Inv, PGM, AcP, GPT, EsD, GLO, AK, PGD, ADA, and GALT/Gt.

Here, we show that the tumor necrosis factor (TNF) superfamily protein LIGHT (homologous to lymphotoxin, exhibits inducible expression, and competes with HSV glycoprotein D for binding to HVEM, a receptor expressed on T lymphocytes) is required for experimental atopic dermatitis, and LIGHT directly controls keratinocyte hyperplasia, and production of periostin, a matricellular protein that contributes to the clinical features of atopic dermatitis as well as other skin diseases such as scleroderma.
We also replicated the associations of the FLG, C11orf30, TMEM232-SLC25A46, TNFRSF6B-ZGPAT, OVOL1, ACTL9 and KIF3A-IL13 loci that were previously reported in GWAS of European and Chinese individuals and a meta-analysis of GWAS for atopic dermatitis.

Our data suggest that ADAM10-mediated E-cadherin proteolysis leads to the impaired cohesion of keratinocytes observed in eczematous dermatitis and provide previously unreported insights into the understanding of the molecular mechanisms involved in inflammatory diseases with loss in epithelial integrity.
Chemokines are important mediators of cell migration, and thymus and activation-regulated chemokine (TARC/CCL17) and macrophage-derived chemokine (MDC/CCL22) are well-known typical inflammatory chemokines involved in atopic dermatitis (AD).
Th2-related chemokines such as thymus and activation-regulated chemokine (TARC/CCL17) and macrophage-derived chemokine (MDC/CCL22), and pro-inflammatory cytokines including interleukin (IL)-1β and IL-6 are considered to play a crucial role in AD.
Here we have shown that keratinocyte-specific deletion of a disintegrin and metalloproteinase 17 (Adam17) triggers T helper 2 and/or T helper 17 (Th2 and/or Th17) cell-driven atopic dermatitis and myeloproliferative disease.
Herein, we demonstrate that Adam17(fl/fl)Sox9-(Cre) mice, generated to model ADAM17-deficiency in human, developed eczematous dermatitis with naturally occurring dysbiosis, similar to that observed in atopic dermatitis.
This is the first study to provide evidence for an association of the ADAM33 polymorphism with AD risk but the strength of this evidence is limited by our small sample size.
Three apoptosis-related genes (NOD2, DUSP1, and ADM) and 8 genes overexpressed in AD skin lesions (CCDC109B, CCL5, CCL8, IFI35, LYN, RAB31, IFITM1, and IFITM2) were induced by IFN-γ in primary keratinocytes.
In this study, we evaluated cytokine expression by various subsets of peripheral blood mononuclear cells from ADEH+ (n = 24) compared with AD without a history of viral infections (ADEH-) (n = 20) before and after treatment with herpes simplex virus (HSV).
AD patients with history of EH display higher total IgE serum levels (ADEH(+) HSV(+) vs ADEH(-) HSV(+) , P < 0.001) and higher sensitization profiles and stronger severity of AD (EASI and SCORAD; ADEH(+) HSV(+) vs ADEH(-) HSV(+) , P < 0.001).
Restoring antimicrobial peptide levels in AD skin via aryl hydrocarbon receptor-dependent transcription regulation can be beneficial by creating a (anti)microbial milieu that is less prone to infection and inflammation.
