Project description:The importance of unanchored Ub in innate immunity has been shown only for a limited number of unanchored Ub-interactors. We investigated what additional cellular factors interact with unanchored Ub and whether unanchored Ub plays a broader role in innate immunity. To identify unanchored Ub-interacting factors from murine lungs, we used His-tagged recombinant poly-Ub chains as bait. These chains were mixed with lung tissue lysates and protein complexes were isolated with Ni-NTA beads. Sample elutions were subjected to mass spectrometry (LC-MSMS) analysis.
Project description:Regulatory T cells (Treg) play a pivotal role in modulating immune responses and were shown to decrease atherosclerosis in murine models. How this effect is brought about remains elusive. We used microarrays to detail the global programme of gene expression in intestinal tissue from chimeric DEREG x Ldlr-/- mice +/- diphteria toxin enabling selective depletion of Treg. Chimeric DEREG x Ldlr-/- mice were kept on a high fat diet for 8 weeks and treated with DT or PBS i.p. for 8 weeks. Upon harvest, intestinal tissue was ascertained from animals from both groups and a gene array was performed.
Project description:To describe the protein profile in hippocampus, colon and ileum tissue’ changing after the old faeces transplants, we adopted a quantitative label free proteomics approach.
Project description:We collected whole genome testis expression data from hybrid zone mice. We integrated GWAS mapping of testis expression traits and low testis weight to gain insight into the genetic basis of hybrid male sterility.
