A new system for lineage ablation is based on transgenic expression of a diphtheria toxin receptor (DTR) in mouse cells and application of diphtheria toxin (DT). To streamline this approach, we generated Cre-inducible DTR transgenic mice (iDTR) in which Cre-mediated excision of a STOP cassette renders cells sensitive to DT. We tested the iDTR strain by(More)
It is generally assumed that new genes would arise by gene duplication mechanisms, because the signals for regulation and transcript processing would be unlikely to evolve in parallel with a new gene function. We have identified here a transcript in the house mouse (Mus musculus) that has arisen within the past 2.5-3.5 million years in a large intergenic(More)
Changes in gene expression are known to occur between closely related species, but it is not yet clear how many of these are due to random fixation of allelic variants or due to adaptive events. In a microarray survey between subspecies of the Mus musculus complex, we identified the mitogen-activated protein-kinase-kinase MKK7 as a candidate for change in(More)
B cells have been shown in various animal models to induce immunological tolerance leading to reduced immune responses and protection from autoimmunity. We show that interaction of B cells with naive T cells results in T cell triggering accompanied by the expression of negative costimulatory molecules such as PD-1, CTLA-4, B and T lymphocyte attenuator, and(More)
In synchronized trampolining, two gymnasts perform the same routine at the same time. While trained gymnasts are thought to coordinate their own movements with the movements of another gymnast by detecting relevant movement information, the question arises how visual and auditory information contribute to the emergence of synchronicity between both(More)
