AD2, a human molecule involved in the interaction of T cells with epidermal keratinocytes and thymic epithelial cells.
Interactions between T cells and epithelial cells of the thymus are essential for normal T cell development, and interactions between T cells and skin epidermal keratinocytes occur in the context of inflammatory skin diseases and cutaneous T cell malignancies. On the basis of observations that the T cell ALL cell line, HSB, bound to IFN-gamma activated epidermal keratinocytes (41 +/- 5% of EK w...
متن کاملSecretion of bioactive interleukin-1beta by dendritic cells is modulated by interaction with antigen specific T cells.
The role of interleukin-1beta (IL-1beta) as a regulator of the immune response, although extensively investigated, is still debated. We then studied the expression of IL-1beta by human dendritic cells (DCs), the professional antigen presenting cells, and its modulation during immune reactions in vitro. Our results show that, on maturation or tetanus toxoid presentation to specific CD4(+) CD40L(...
متن کاملInterleukin-18 synthesis and secretion by dendritic cells are modulated by interaction with antigen-specific T cells.
We show that interleukin-18 is constitutively produced by dendritic cells; synthesis and secretion are poorly affected by maturative stimuli. Challenge of dendritic cells with autologous anti-tetanus toxoid T lymphocytes results in a secretory switch, with induction of secretion of biologically active interleukin-18 and decrease of its intracellular content. Similarly, when dendritic cells are ...
متن کاملDendritic 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...
متن کاملThe 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...
