Abstract

Dendritic cells (DCs) operate at the intersection of the innate and adaptive immune systems. DCs can promote or inhibit adaptive immune responses against neuroantigens. While DC intrinsic properties, i.e., their maturation state or the subset they belong to, are important determinants of the outcome of an autoimmune reaction, tissue-specific cues might also be relevant for the function of DCs. Thus, a better understanding of the performance of distinct DC subsets in specific anatomical niches, not only in lymphoid tissue but also in non-lymphoid tissues such as the meninges, the choroid plexus, and the inflamed CNS parenchyma, will be instrumental for the design of immune intervention strategies to chronic inflammatory diseases that do not put at risk basic surveillance functions of the immune system in the CNS. Here, we will review modern concepts of DC biology in steady state and during autoimmune neuroinflammation.
