Dendritic cells (DCs) are key directors of tolerogenic and immunogenic immune responses. During the steady state, DCs maintain T cell tolerance to self-antigens by multiple mechanisms including inducing anergy, deletion, and Treg activity. All of these mechanisms help to prevent autoimmune diseases or other hyperreactivities. Different DC subsets contribute to pathogen recognition by expression...

Exposure to environmental toxicants can alter a range of cellular functions involved in the immune response. Increased expression of the stress protein metallothionein 1 (MT1) is one example hereof. Previously, it has been reported that MT1 has several immunosuppressive properties. Furthermore, we earlier showed that functionally tolerogenic dendritic cells (DCs) expressed increased mRNA levels...

Previous studies have shown the b-catenin signaling pathway to promote the development of tolerogenic dendritic cells (DCs) that are capable of driving regulatory T cell (Treg) differentiation. Interestingly, tolerogenic DCs have recently been described to play a role in carcinogenesis. However, the molecular mechanisms underlying the establishment of immune tolerance by this DC population are ...

hla-g is a tolerogenic molecule that expresses in cytotrophoblast cells and plays an important role in immune response suppression in maternal decidua. interactions between the extracellular domains of the hla-g protein with cell receptors of the immune system are well-known.this  study  investigated  the  association  between  hla-g  gene  polymorphism  with repeated implantation failure (rif)...

Dendritic cells (DC) are antigen-presenting cells that play a pivotal role in regulating innate and adaptive immune responses. In autoimmunity, DC act as a double-edged sword since on one hand they initiate adaptive self-reactive responses and on the other they play a pivotal role in promoting and maintaining tolerance. Thus, DC are the most important cells in either triggering self-specific re...

objective(s) recent studies on human indicate that the introduction of therapeutic use of tolerogenic dendritic cell (dc) for chronic inflammatory conditions is imminent. for the purpose of defining cgrp potency in tolerogenic dc production, we investigated the phenotype and il-'2 production of dcs generated from the monocytes of rheumatoid arthritis (ra) patients in the presence of the ca...
