Wnt/β-catenin signaling controls multiple steps of neural crest development, ranging from neural crest induction, lineage decisions, to differentiation. In mice, conditional β-catenin inactivation in premigratory neural crest cells abolishes both sensory neuron and melanocyte formation. Intriguingly, the generation of melanocytes is also prevented by(More)
The CD27/CD70-interaction has been shown to provide a costimulatory and survival signal for T cells in vitro and in vivo. Recently, CD70 expression by DC was found to be important for the priming of CD8+ T cells. We show here that blocking CD70 interactions has a significant impact on priming of CD8+ T cell responses by vaccinia virus (VV), Listeria(More)
During vertebrate development, neural crest cells are exposed to multiple extracellular cues that drive their differentiation into neural and non-neural cell lineages. Insights into the signals potentially involved in neural crest cell fate decisions in vivo have been gained by cell culture experiments that have allowed the identification of instructive(More)
Auto-reactivity of T cells is largely prevented by central and peripheral tolerance. Nevertheless, immunization with certain self-antigens emulsified in CFA induces autoimmunity in rodents, suggesting that tolerance to some self-antigens is not robust. To investigate the fate of nervous system-specific CD8(+) T cells, which only recently came up as being(More)
