Tolerogenic Dendritic Cells for Regulatory T Cell Induction in Man
Dendritic cells (DCs) are highly specialized professional antigen-presenting cells that regulate immune responses, maintaining the balance between tolerance and immunity. Mechanisms via which they can promote central and peripheral tolerance include clonal deletion, the inhibition of memory T cell responses, T cell anergy, and induction of regulatory T cells (Tregs). These properties have led t...
متن کاملPharmacological induction of tolerogenic dendritic cells and regulatory T cells.
Immunosuppressive and anti-inflammatory agents are able to generate tolerogenic DCs, leading, in some cases, to induction or enhancement of regulatory T cells with suppressive activity. This novel mechanism of action, shared by several immunosuppressive and anti-inflammatory agents, is becoming firmly established and contributes to explain their functional properties. The possibility to manipul...
متن کاملHow tolerogenic dendritic cells induce regulatory T cells.
Since their discovery by Steinman and Cohn in 1973, dendritic cells (DCs) have become increasingly recognized for their crucial role as regulators of innate and adaptive immunity. DCs are exquisitely adept at acquiring, processing, and presenting antigens to T cells. They also adjust the context (and hence the outcome) of antigen presentation in response to a plethora of environmental inputs th...
متن کاملApoptotic Cell-induced Tolerogenic Dendritic Cells Facilitate Development of CD4+ and CD8+ Regulatory T cell Subsets
Objective: Dendritic cells (DCs) play an important role in regulating T cell-mediated immune responses; however, the mechanisms of DC-mediated immune responses have not been fully elucidated. Regulatory T cells (Tregs) including CD4+ and CD8+ Tregs play an essential role in induction of immune tolerance in vivo. It is unclear how DCs regulate development of Tregs. Our objective is to observe wh...
متن کاملCritical role for TNF in the induction of human antigen-specific regulatory T cells by tolerogenic dendritic cells.
TNF is a pleiotropic cytokine with differential effects on immune cells and diseases. Anti-TNF therapy was shown to be effective in rheumatoid arthritis but proved inefficient or even detrimental in other autoimmune diseases. We studied the role of TNF in the induction of Ag-specific regulatory T cells (Tregs) by tolerogenic vitamin D3-modulated human dendritic cells (VD3-DCs), which previously...
