Tolerogenic dendritic cells are efficiently generated using minocycline and dexamethasone

Bone marrow dendritic cells deficient for CD40 and IL-23p19 are tolerogenic in vitro

Objective(s): In addition to pro-inflammatory role, dendritic cells (DCs) can also be anti-inflammatory when they acquire tolerogenic phenotype. In this study we tested the role of CD40 and IL-23p19 in antigen presenting function of bone marrow-derived DCs (BMDCs) by comparing BMDCs derived from CD40 knockout (CD40KO-DCs) and IL-23p19 (IL-23p19KO-DCs) knockout mice wit...

CD40 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...

Tolerogenic 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...

Tolerogenic Semimature Dendritic Cells

Differential protein pathways in 1,25-dihydroxyvitamin d(3) and dexamethasone modulated tolerogenic human dendritic cells.

Tolerogenic dendritic cells (DC) that are maturation-resistant and locked in a semimature state are promising tools in clinical applications for tolerance induction. Different immunomodulatory agents have been shown to induce a tolerogenic DC phenotype, such as the biologically active form of vitamin D (1,25(OH)(2)D(3)), glucocorticoids, and a synergistic combination of both. In this study, we ...
