Pharmacologic Induction of Endotoxin Tolerance in Dendritic Cells by L-Kynurenine

Dendritic Cells in Transplant Tolerance

Dendritic cells (DCs) are a heterogeneous family of professional APCs involved in priming adaptive immune responses. Donor DCs (direct pathway of allorecognition) and recipient DCs presenting processed donor major histocompatibility complex (MHC) as peptides (indirect pathway of allorecognition) participate actively in graft rejection by stimulating recipient T cell responses following organ tr...

Mechanisms of Tolerance Induction by Dendritic Cells In Vivo

Dendritic cells (DCs) are a heterogeneous population playing a pivotal role in immune responses and tolerance. DCs promote immune tolerance by participating in the negative selection of autoreactive T cells in the thymus. Furthermore, to eliminate autoreactive T cells that have escaped thymic deletion, DCs also induce immune tolerance in the periphery through various mechanisms. Breakdown of th...

tolerance induction by cd40 blocking through specific antibody in dendritic cells

blocking antibodies are valuable tools for inhibiting the specific receptor- ligand interactions. the interaction of co-stimulatory molecules on the antigen presenting cells with their ligands on t cells is an essential step for t cell activation. in the present study, the effect of blocking antibody against cd40 on its t cell stimulatory potential is investigated. the dcs (dendritic cells) wer...

Modulation of Dendritic Cells for Tolerance Induction*

Dendritic cells (DC) are uniquely well-equipped antigen (Ag) presenting cells that initiate and regulate immune responses. DC play a dualistic role in the regulation of immune responses. They initiate adaptive immunity by the activating naive lymphocytes and are powerful stimulators of natural killer cells – the crucial cellular instigators of the innate immune system. Furthermore, DC induce ce...
