Helicobacter pyloridirects tolerogenic programming of dendritic cells

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...

Regulatory Multitasking of Tolerogenic Dendritic Cells – Lessons Taken from Vitamin D3-Treated Tolerogenic Dendritic Cells

Tolerogenic dendritic cells (DCs) work through silencing of differentiated antigen-specific T cells, activation and expansion of naturally occurring T regulatory cells (Tregs), transfer of regulatory properties to T cells, and the differentiation of naïve T cells into Tregs. Due to an operational definition based on T cell activation assays, the identity of tolerogenic DCs has been a matter of ...

Tolerogenic Dendritic Cells in Clinical Practice

Dendritic cells (DC) play a critical role in maintaining immune tolerance to self-antigens and have become a promising immunotherapeutic tool for treating autoimmune diseases such as rheumatoid arthritis (RA). Tolerogenic DC (tolDC) with stable immunosuppressive function can be generated in the laboratory. These modified tolDC induce antigen-specific T cell tolerance in vitro and in vivo, and c...
