Innate lymphoid cells and the skin
نویسندگان
چکیده
Innate lymphoid cells are an emerging family of effector cells that contribute to lymphoid organogenesis, metabolism, tissue remodelling and protection against infections. They maintain homeostatic immunity at barrier surfaces such as lung, skin and gut (Nature 464:1367-1371, 2010, Nat Rev Immunol 13: 145-149, 2013). Several human and mouse studies suggest a role for innate lymphoid cells in inflammatory skin conditions including atopic eczema and psoriasis. Here we review the innate lymphoid cell family and discuss their function in the skin and during inflammation.

Innate Lymphoid Cells in the Skin
Innate lymphoid cells (ILCs) are part of a heterogeneous family of innate immune cells with newly identified roles in mediating immunity, tissue homeostasis, and pathologic inflammation. Here, we review recent studies delineating the roles of ILCs in the pathogenesis of multiple inflammatory skin disorders and their unique effector functions. Finally, we address how these studies have informed ...
متن کاملA new player on the psoriasis block: IL-17A- and IL-22-producing innate lymphoid cells
Innate lymphoid cells (ILCs) are a recently discovered family of innate immune cells belonging to the lymphoid lineage, yet lacking antigen-specific receptors. ILCs were first identified in the intestinal tract, where they contribute to epithelial barrier integrity and host responses to commensal microbes. Teunissen et al. (in the current issue) and Villanova et al. (2014) now suggest an import...
متن کاملEpidermal mucus, a major determinant in fish health: a review
Fish epidermal mucus contains innate immune components, secreted by globlet cells that provide the primary defence against different pathogenic microbes and act as a barrier between fish and its immediate niche. The major function of mucus includes entrapment and sloughing of microbes. The mucus also contains many factors such as antimicrobial peptides (AMPs), lysozymes, lectins, proteases, etc...
متن کاملNovel insights into the role of immune cells in skin and inducible skin-associated lymphoid tissue (iSALT)
The skin is equipped with serial barriers that provide rapid and efficient protection against external intruders. Beneath the epidermal physical barriers of the stratum corneum and the tight junctions, the integrated immune systems in both the epidermis and the dermis act in a coordinated manner to protect the host. This "immunological" barrier is composed of various cells, including skin-resid...
متن کاملHallmarks of Tissue-Resident Lymphocytes
Although they are classically viewed as continuously recirculating through the lymphoid organs and blood, lymphocytes also establish residency in non-lymphoid tissues, most prominently at barrier sites, including the mucosal surfaces and skin. These specialized tissue-resident lymphocyte subsets span the innate-adaptive continuum and include innate lymphoid cells (ILCs), unconventional T cells ...
