Tolerogenic and Activatory Plasmacytoid Dendritic Cells in Autoimmunity
Plasmacytoid dendritic cells (pDCs) are a particular subset of DCs that link innate and adaptive immunity. They are responsible for the substantial production of type 1 interferon (IFN-I) in response to viral RNA or DNA through activation of TLR7 and 9. Furthermore, pDCs present antigens (Ag) and induce naïve T cell differentiation. It has been demonstrated that pDCs can induce immunogenic T ce...
متن کاملPredominant Role of Plasmacytoid Dendritic Cells in Stimulating Systemic Autoimmunity
Plasmacytoid dendritic cells (pDCs), which are prominent type I interferon (IFN-I)-producing immune cells, have been extensively implicated in systemic lupus erythematosus (SLE). However, whether they participate critically in lupus pathogenesis remains unknown. Recent studies using various genetic and cell type-specific ablation strategies have demonstrated that pDCs play a pivotal role in the...
متن کاملPlasmacytoid dendritic cells in angiolymphoid hyperplasia with eosinophilia
Background: Angiolymphoid hyperplasia with eosinophilia (ALHE) is characterized by irregularly-shaped blood vessels with an inflammatory infiltrate. While absent from normal skin, plasmacytoid dendritic cells (pDCs) infiltrate the skin upon injury and during several infectious, inflammatory, and neoplastic entities. In addition to providing anti-viral resistance, pDCs link the innate and adapti...
متن کاملCD40 Knocked Down Tolerogenic Dendritic Cells Decrease Diabetic Injury
Background: Type-1 diabetes (T1D) is an autoimmune disease in which T lymphocytes destroy insulin-producing β-cells. Control of self-reactive T lymphocytes and recovery of diabetic injury is the end point of T1D. Objective: To investigate generation of tolerogenic dendritic cells (tolDCs) as an innovative method of diabetes therapy. Methods: Lentivirus vector production was achieved by GIPZ mou...
متن کاملTolerogenic dendritic cells.
Dendritic cells (DCs) have several functions in innate and adaptive immunity. In addition, there is increasing evidence that DCs in situ induce antigen-specific unresponsiveness or tolerance in central lymphoid organs and in the periphery. In the thymus DCs generate tolerance by deleting self-reactive T cells. In peripheral lymphoid organs DCs also induce tolerance to antigens captured by recep...
