Atopic dermatitis (AD) may be more common than previously thought in adults aged ≥60 years, a population underrepresented in clinical trials. Rigorous demonstration of efficacy and safety in older adults is clinically important due to distinct disease presentations in this group, age-related immune shifts, changes in drug metabolism and risks assoc...
Background
Atopic dermatitis is a prevalent condition in children and can be effectively managed with medications such as topical calcineurin inhibitors (pimecrolimus or tacrolimus). A key unresolved safety concern is whether use of topical calcineurin inhibitors is associated with cancer. We systematically reviewed the risk of cancer in patients w...
Background
Atopic dermatitis (AD, eczema) is driven by a combination of skin barrier defects, immune dysregulation, and extrinsic stimuli (eg. allergens, irritants, microbes). The role of environmental allergens (aeroallergens) in triggering AD remains unclear.
Objective
Systematically synthesize evidence regarding the benefits and harms of allerg...
BACKGROUND
The influence of diet on atopic dermatitis (AD) is complex, and the use of dietary elimination as a treatment has conflicting views.
OBJECTIVE
To systematically review the benefits and harms of dietary elimination for the treatment of AD.
METHODS
We searched MEDLINE, EMBASE, AMED, PsycINFO and CENTRAL from inception to Jan 18, 2022, wi...
Skin barrier dysfunction, a defining feature of atopic dermatitis (AD), arises from multiple interacting systems. In AD, skin inflammation is caused by host–environment interactions involving keratinocytes, as well as tissue-resident immune cells such as type 2 innate lymphoid cells, basophils, mast cells, and T-helper type 2 cells, which produce t...

Atopic dermatitis (AD) is the most common chronic skin inflammatory disease, with a profound impact on patients’ quality of life. AD varies considerably in clinical course, age of onset and degree to which it is accompanied by allergic and non-allergic comorbidities. Skin barrier impairment in both lesional and nonlesional skin is now recognized as...
Background
Eczema herpeticum (EH) is a rare complication of atopic dermatitis (AD) caused by disseminated herpes simplex virus (HSV) infection. The role of rare and/or deleterious genetic variants in disease etiology is largely unknown. This study aimed to identify genes that harbor damaging genetic variants associated with HSV infection in AD with...
Atopic dermatitis (AD) is the most common chronic and relapsing inflammatory skin disease. AD is typically characterized by skewed T helper (Th) 2 inflammation, yet other inflammatory profiles (Th1, Th17, Th22) have been observed in human patients. How cytokines from these different Th subsets impact barrier function in this disease is not well und...
Keratinocytes express many pattern recognition receptors that enhance the skin's adaptive immune response to epicutaneous antigens. We have shown that these pattern recognition receptors are expressed below tight junctions (TJ), strongly implicating TJ disruption as a critical step in antigen responsiveness. To disrupt TJs, we designed peptides ins...
Atopic dermatitis (AD) patients are commonly colonized with Staphylococcus aureus (ADS.aureus+) but what differentiates this group from noncolonized AD subjects (ADS.aureus-) has not been well-studied. To evaluate whether these two groups have unique phenotypic or endotypic features we performed a multi-center, cross-sectional study enrolling ADS.a...
Atopic dermatitis (AD) is the most common inflammatory skin disease with no well-delineated cause or effective cure. Here we show that the p53 family member p63, specifically the ΔNp63, isoform has a key role in driving keratinocyte activation in AD. We find that overexpression of ΔNp63 in transgenic mouse epidermis results in a severe skin phenoty...
The skin, the largest organ of the body, is an essential barrier that under homeostatic conditions efficiently protects and/or minimizes damage from both environmental (e.g. microorganisms, physical trauma, ultraviolet radiation) and endogenous (e.g., cancers, inflammation) factors. This formidable barrier function resides mainly in the epidermis,...
Atopic Dermatitis (AD), the most common chronic inflammatory skin disease, is characterized by an overactive immune response to a host of environmental allergens and dry, itchy skin. Over the past decade important discoveries have demonstrated that AD develops in part from genetic and/or acquired defects in the skin barrier. Histamine is an aminerg...
An epidermal sample is placed into a sample holder formed as a sandwich assembly. The sample holder is placed in an upper well within a lower well to be exposed to media in both wells. Properties of the sample can be studied, such as paracellular flux, transepidermal electric resistance, reaction to compounds, and epidermal barrier recovery.
Orchestrating when and how the cutaneous innate immune system should respond to commensal or pathogenic microbes is a critical function of the epithelium. The cutaneous innate immune system is a key determinant of the physical, chemical, microbial, and immunologic barrier functions of the epidermis. A malfunction in this system can lead to an inade...
Atopic dermatitis (AD) is characterized by epidermal tight junction (TJ) defects and a propensity for Staphylococcus aureus skin infections. S. aureus is sensed by many pattern recognition receptors, including Toll-like receptor 2 (TLR2). We hypothesized that an effective innate immune response will include skin barrier repair, and that this respon...
For at least half a century, noninvasive techniques have been available to quantify skin barrier function, and these have shown that a number of human skin conditions and disorders are associated with defects in skin permeability. In the past decade, several genes responsible for skin barrier defects observed in both monogenetic and complex polygen...
Aldo-keto reductase 1C3 (AKR1C3) has been shown to mediate the metabolism of sex hormones and prostaglandin D(2) (PGD(2)), a lipid mediator that promotes skin inflammation in atopic dermatitis (AD). As both have a role in skin function and pathology, we first sought to investigate the expression pattern of AKR1C3 in normal human epidermis. Immunofl...
Disruption of the epithelial barrier might be a risk factor for allergen sensitization and asthma. Viral respiratory tract infections are strongly associated with asthma exacerbation, but the effects of respiratory viruses on airway epithelial barrier function are not well understood. Many viruses generate double-stranded RNA, which can lead to air...
. Eczema herpeticum (EH) is a potentially serious, systemic complication in subjects with atopic dermatitis (AD) caused by herpes simplex virus (HSV). The innate immune dysregulation that predisposes these subjects to cutaneous viral infections is not well understood. We tested the hypothesis that defects in mannan-binding lectin (MBL) may be assoc...
Atopic dermatitis (AD) is characterized by dry skin and a hyperactive immune response to allergens, 2 cardinal features that are caused in part by epidermal barrier defects. Tight junctions (TJs) reside immediately below the stratum corneum and regulate the selective permeability of the paracellular pathway.
We evaluated the expression/function of...
Atopic dermatitis (AD) is a common chronic inflammatory skin disease that affects patients of all ages. The etiology is multifactorial, resulting from complex interactions of the immune system, environmental stimuli, and susceptibility genes. The prevalence of AD is increasing in industrialized nations, with as estimates as high as 20% of children...
Atopic dermatitis (AD) is a common chronic inflammatory skin disease that has increased in prevalence over the last half century. A growing body of evidence suggests that there are a variety of defects in the innate immune system that collectively affect the development and severity of AD. The reduction in antimicrobial peptides, diminished recruit...
The growing presence of quantum dots (QD) in a variety of biological, medical, and electronics applications means an increased risk of human exposure in manufacturing, research, and consumer use. However, very few studies have investigated the susceptibility of skin to penetration of QD - the most common exposure route- and the results of those tha...
