T cells populate the skin to provide an effective immunosurveillance against external insults and to maintain tissue homeostasis. Most cutaneous T cells are αβ T cells, however, γδ T cells also exist although in much lower frequency. Different subsets of αβ T cells can be found in the skin, such as short-lived effector T cells, central memory T cells, effector memory T cells, and tissue-resident memory T cells. Their differential biology, function, and location provide an ample spectrum of immune responses in the skin. Foxp3+ memory regulatory T cells have a pivotal role in maintaining homeostasis in the skin and their dysregulation has been linked with different skin pathologies. The skin also contains populations of non-classical T cells, such as γδ T cells, NK T cells, and MR1-restricted T cells. Their role in skin homeostasis and response to pathogens has been well established in the past years, however, there is also growing evidence of their role in mediating allergic skin inflammation and promoting sensitization to allergens. In this review, we provide an updated overview on the different subsets of T cells that populate the skin with a specific focus on their role in allergic skin inflammation.
期刊介绍:
This review journal provides the most current information on basic and translational research in immunology and related fields. In addition to invited reviews, the journal accepts for publication articles and editorials on relevant topics proposed by contributors. Each issue of International Reviews of Immunology contains both solicited and unsolicited review articles, editorials, and ''In-this-Issue'' highlights. The journal also hosts reviews that position the authors'' original work relative to advances in a given field, bridging the gap between annual reviews and the original research articles.
This review series is relevant to all immunologists, molecular biologists, microbiologists, translational scientists, industry researchers, and physicians who work in basic and clinical immunology, inflammatory and allergic diseases, vaccines, and additional topics relevant to medical research and drug development that connect immunology to disciplines such as oncology, cardiovascular disease, and metabolic disorders.
Covered in International Reviews of Immunology: Basic and developmental immunology (innate and adaptive immunity; inflammation; and tumor and microbial immunology); Clinical research (mechanisms of disease in man pertaining to infectious diseases, autoimmunity, allergy, oncology / immunology); and Translational research (relevant to biomarkers, diagnostics, vaccines, and drug development).
