The G protein‐coupled receptor 15 (GPR15) regulates cutaneous immunology by maintaining dendritic epidermal T cells and regulating the skin microbiome

The Effect of Beta Interferon on Dendritic Cells and Cytokine Synthesis by CD4+ T Cells

Background: Dendritic cells (DC) are a key regulator of the immune response, and interferon- beta (IFN-β) is considered an immunomodulatory molecule for DC. Objective: The purpose of this study was to evaluate the ability of IFN-β treated DC to induce cytokine secretion by CD4+ T cells. Methods: Dendritic cells were generated from blood monocytes with granulocyte-monocyte colony-stimulating fac...

Human Leukocyte Antigen-G Expression on Dendritic Cells Induced by Transforming Growth Factor-β1 and CD4+ T Cells Proliferation

Background: During antigen capture and processing, mature dendritic cells (DC) express large amounts of peptide-MHC complexes and accessory molecules on their surface. DC are antigen-presenting cells that have an important role in tolerance and autoimmunity. The transforming growth factor-beta1 (TGF-β1) cytokine has a regulatory role on the immune and non-immune cells. The aim of this study is ...

Dendritic epidermal T cells regulate skin antimicrobial barrier function.

The epidermis, the outer layer of the skin, forms a physical and antimicrobial shield to protect the body from environmental threats. Skin injury severely compromises the epidermal barrier and requires immediate repair. Dendritic epidermal T cells (DETC) reside in the murine epidermis where they sense skin injury and serve as regulators and orchestrators of immune responses. Here, we determined...

Costimulation of Dendritic Epidermal T Cells by a New NKG2D Ligand Expressed Specifically in the Skin

Killing of skin-derived tumor cells by mouse dendritic epidermal T-cells.

Dendritic epidermal T-cells (DETC) are a unique population of T-cells that reside normally in mouse epidermis and express a gamma delta T-cell receptor. We have reported previously that DETC acquire in culture the capacity to lyse the YAC-1 lymphoma, a conventional target for natural killer cells. The aim of the present study was to characterize this cytotoxic potential, using a spectrum of ski...
