Atopic Dermatitis: Essential Issues Although SALT are still concep-tual tissues, this hypothesis proposes Dendritic type, accessory cells within the mammalian thymic microenvironment. Although iSALT may not be classified as a typical tertiary lymphoid organ, it provides specific antigen presentation sites in the skin. The existence of a specialized set of skin-associated lymphoid tissues (SALT) was proposed several years ago as a means of accounting for (a) epidermotropism of certain malignant lymphocytes, (b) immunocompetent cells within skin, and (c) expression of histocompatibil­ ity antigens on cutaneous cells derived from hemato­ poietic precursors. In addition, the formation of a lymphoid cluster, named inducible skin-associated lymphoid tissue (iSALT), has been reported during skin inflammation. DOI: 10.2183/pjab.92.20 Corpus ID: 15485350. Animals (Basel). The mucosa-associated lymphoid tissue (MALT), also called mucosa-associated lymphatic tissue, is a diffuse system of small concentrations of lymphoid tissue found in various submucosal membrane sites of the body, such as the gastrointestinal tract, nasopharynx, thyroid, breast, lung, salivary glands, eye, and skin. They offered the term SALT (skin-associated lymphoid tissues) for these putative skin-associated tissues (Streilein, 1978, 1983, 1985). proposed that lymphoid tissues analo-gous to MALT in submucosal areas may form within the skin under the inflam-matory condition. This book provides crucial information not only for poultry health professionals and avian biologists, but also for comparative and veterinary immunologists, graduate students and veterinary students with an interest in avian immunology. However, a great deal of research interest has recently emerged with the focus on mucosal-associated lymphoid tissues (MALT) in teleosts that include four tissue components: gills, gut, nasopharynx, and skin. However, it remains unclear whether and how T cells are activated in the skin . Arch Dermatol. Mucosa-associated lymphoid tissue. This in-depth work discusses how these antigen-presenting cells are modulated by various physicochemical agents (such as UV light) and how they can be infected by the AIDS virus. Skin is subjected to physicochemical stresses such as irradiation with ultraviolet light that alter dramatically its immunologic properties. Mucosal Vaccines is organized in a unique format in which basic, clinical, and practical aspects of the mucosal immune system for vaccine development are described and discussed. 2.

Author J W Streilein. J Clin Pathol. 1989;18:22-30. doi: 10.1159/000416834. Cellular elements of the immune response predominate in the epidermis. Some, but not all, T lymphocytes display special affinity for skin and draining lymph nodes. Although iSALT may not be classified as a typical tertiary lymphoid organ, it provides specific antigen presentation sites in the skin. • Less organized secondary lymphoid tissues are associated with the linings of multiple organ systems, including the skin and the reproductive, respiratory, and gastrointestinal tracts, all of which protect us against external pathogens. Novel concept of iSALT (inducible skin-associated lymphoid tissue) in the elicitation of allergic contact dermatitis Medical browser ? The observations of elicitation of CHS lead to the emerging novel concept of iSALT (inducible skin-associated lymphoid tissue). PMC Introduction Allergic contact dermatitis (ACD), such as metal allergy and plant allergy, is a major occupational skin disease that affects approximately 15 to 20% of the general population all over the world. Responsibility for the establishment and integration of SALT rests with keratinocytes, Langerhans cells, and immunocompetent lymphocytes, each of which contributes uniquely to the synthesis.
