National Center for Biotechnology Information, U.S. National Library of Medicine 8600 Rockville Pike, Bethesda MD, 20894 USA In addition to the role of T and B cells in AD, other innate immune cells have also been implicated in the pathogenesis of AD, including eosinophils and mast cells. [10, 11] More recently, basophils and newly identified innate immune cells called group 2 innate lymphoid cells (ILC2s) have been shown to underlie the pathogenesis of AD. [12, 13, 14, 15, 16] Together, basophils and ILC2s are critical sources of the type 2 cytokines IL-4, IL-5, and IL-13. [12, 13] Further, these cells appear to be potently regulated by a family of epithelial cell‒derived cytokines directly released from damaged keratinocytes, including thymic stromal lymphopoietin (TSLP), IL-25, and IL-33. [17] Taken together, these studies highlight a new paradigm in which, in addition to classical adaptive Th2 cells, innate type 2 immune cells play critical roles in the etiology of AD through interactions with epidermal-derived cytokines.

Author An Amazon Book with Buzz: "The Other Woman" van Reijsen FC Transient recurrent immunodeficiency is considered to be one of the factors, predisposing the development of atopy. In the skin of patients decrease in number of Langerhans cells and reduction of HLA-DR antigen expression on them, increase of the number of Langerhans cells with IgE-receptors are detected. From the immune disorders elevated levels of serum IgE are observed that is believed to be genetically determined, although this sign is not observed in all patients with neurodermatitis; the lack of T-lymphocytes, especially having suppressor properties, is caused probably by defective beta-adrenergic receptors. The number of B-cells is normal, but there is a slight increase in the number of B-lymphocytes, bearing receptors for Fc-fragment of IgE. Neutrophilic chemotaxis, a function of natural killer cells, production of interleukin-1 by monocytes of patients in comparison with control observations are reduced. The presence of immune system defect serves apparently as one of the major causes of patients’ susceptibility to infectious diseases. Pathogenetic importance of non-bacterial allergy on allergens of an infectious origin is shown. Neurovegetative disturbances are given with both etiological and aggravating significances in the course of the disease. Dialogues in Dermatology quizzes Allergy card Neurodermatitis can be very itchy, so dermatologists offer tips that can lessen the itch. Other skin conditions. People with a personal or family history of dermatitis, eczema, psoriasis or similar skin conditions are more likely to develop neurodermatitis. J Allergy Clin Immunol. 2000; 105: 782-787 Serologic allergy testing may be performed, but it does not always have reliable results. The quality of this kind of testing often depends on the laboratory which analyzes the results. Intradermal testing, whereby small amounts of test allergens are injected in the skin and wheal (a red bump) response is measured, may also used to identify the cause of your pet's allergic reaction. Apply cool, wet compresses. These may soothe the skin and relieve the itch. Putting a cool, wet compress on the affected skin for a few minutes before you apply a medicated cream helps it soak into the skin. Need a Curbside Consult?

There is marked thickening of the papillary dermis with bundles of collagen arranged in vertical streaks (). Scattered inflammatory cells and some fibroblasts are usually present in this region of the dermis.

Sometimes in the areas of scratching depigmentation develops. In the presence of pronounced infiltration and lichenification, hypertrophic warty foci of lesions can occur. Rare variants include depigmented, linear, moniliform, decalvans, psoriasiform neurodermatitis, and Pautrier’s giant lichenification.
