(author), Pasmans, S.G.M.A. (author)Background: Atopic dermatitis (AD) is a chronic inflammatory skin disease that affects 10 to 20% of children and between 2 and 15% of the adults in Western Europe. Since 2000, therapeutic clothing or functional textiles based on silver or chitosan as antibacterial agents were introduced for AD. These agents aim to reduce skin colonization with...article 2021

(author), Pasmans, S.G.M.A. (author), Pasmans, S.G.M.A. (author)Background: Exposure to microbes may be important in the development of atopic disease. Atopic diseases have been associated with specific characteristics of the intestinal microbiome. The link between intestinal microbiota and food allergy has rarely been studied, and the gold standard for diagnosing food allergy (double-blind placebo...article 2018

Totté, J. (author), de Wit, J. (author), Pardo, L. (author), Schuren, F. (author), van Doorn, M. (author), Pasmans, S. (author)Background: Atopic dermatitis (AD) is associated with reduced skin microbial diversity and overgrowth of Staphylococcus (S.) aureus. However, the importance of S. aureus colonisation in the complex pathogenesis remains unclear and studies on the effect of anti-staphylococcal therapy in non-infected AD show contradictory results. Long-term...article 2017

Terwoert, J. (author)Irritants – in this article to be understood as being chemical irritants – are substances that may cause injuries to the skin, the eyes or the airways after a single exposure. These injuries may range from small, initially invisible injuries after exposure to weak irritants up to chemical burns after exposure to very strong irritants (i.e....other 2014

(author), Bruijnzeel-Koomen, C.A. (author), Pasmans, S.G.M.A. (author)Background: About 10 to 20% of children in West European countries have atopic dermatitis (AD), often as part of the atopic syndrome. The full atopic syndrome also consists of allergic asthma, allergic rhinitis and food allergy. Treatment approaches for atopic dermatitis and asthma include intermittent anti-inflammatory therapy with...article 2014

van der Veen, J.W. (author), Soeteman-Hernández, L.G. (author), Ezendam, J. (author), Stierum, R. (author), Kuper, F.C. (author), van Loveren, H. (author)Allergic contact dermatitis (ACD) is a hypersensitivity immune response induced by small protein-reactive chemicals. Currently, the murine local lymph node assay (LLNA) provides hazard identification and quantitative estimation of sensitizing potency. Given the complexity of ACD, a single alternative method cannot replace the LLNA, but it is...article 2014

(author)Hand dermatitis is a prevalent disease with an episodic, chronic character. The use of medical resources is high and is often related to reduced (work) functioning. The burden is therefore high for patients and society. Management of hand dermatitis is often unsatisfactory, and for this reason prevention is important. The effectiveness of...article 2011

van Triel, J.J. (author), Arts, J.H. (author), Muijser, H. (author), Kuper, C.F. (author), TNO Kwaliteit van Leven (author)Previously, the contact allergen dinitrochlorobenzene (DNCB) was identified as a sensitizer by inhalation in BALB/c mice; in addition, DNCB induced a lymphocytic infiltrate in the larynx of dermally sensitized Th1-prone Wistar rats upon a single inhalation challenge. In the present study, repeated inhalation exposures to DNCB were investigated...article 2010

(author), TNO Kwaliteit van Leven (author)Background: Wet-wrap treatment (WWT) with diluted topical steroids is widely used in atopic dermatitis (AD). Mice with transgenic overexpression of human apolipoprotein C1 (APOC1) in the liver and the skin are not only characterized by hyperlipidaemia and raised IgE levels, but also by pruritic dermatitis and a disturbed skin barrier function,...article 2009

(author), TNO Kwaliteit van Leven (author)There are currently no validated animal models that can identify low molecular weight (LMW) respiratory sensitizers. The Local Lymph Node Assay (LLNA) is a validated animal model developed to detect contact sensitizers using skin exposure, but all LMW respiratory sensitizers tested so far were also positive in this assay. Discrimination between...article 2009

(author), TNO Kwaliteit van Leven (author)All LMW respiratory allergens known to date can also induce skin allergy in test animals. The question here was if in turn skin allergens can induce allergy in the respiratory tract. Respiratory allergy was tested in Th2-prone Brown Norway (BN) rats by dermal sensitization with the contact allergen dinitrochlorobenzene (DNCB; 1%, day 0; 0.5%,...article 2008

(author), TNO Kwaliteit van Leven (author)Mice with transgenic expression of human apolipoprotein C1 (APOC1) in liver and skin have strongly increased serum levels of cholesterol, triglycerides, and free fatty acids, indicative of a disturbed lipid metabolism.

(author), TNO Defensie en Veiligheid (author)The accelerated migration of Langerhans cells (LCs) out of the epidermis and up-regulation of maturation markers, upon treatment with subtoxic concentrations of chemicals, were used as the criteria to determine the potential of allergenic chemicals capable of inducing a hapten-specific delayed-type hypersensitivity reaction.

(author), TNO Defensie en Veiligheid (author)Skin irritants and contact allergens reduce the number of Langerhans cells (LCs). It has been assumed that this reduction is due their migration to the draining lymph node (LN) for initiating immune sensitization in a host. Skin irritation, however, as opposed to contact allergy is not considered to be an immunological disease. Nevertheless,...article 2006

Arts, J.H.E. (author), Mommers, C. (author), de Heer, C. (author), TNO Kwaliteit van Leven (author)A literature study was performed to evaluate dose-response relationships and no-effect levels for sensitization and elicitation in skin- and respiratory allergy. With respect to the skin, dose-response relationships and no-effect levels were found for both intradermal and topical induction, as well as for intradermal and topical elicitation of...article 2006
