Project description:TGF-b is an important pleiotropic cytokine with potent immunoregulatory properties. Although many previous reports have been proposed for the immunoregulatory functions of TGF-b on T cells, such as the suppression of cell proliferation, cytokine production and cytokine signaling, as well as the induction of apoptosis, it is not well elucidated whether the each effect of TGF-b on T cells is dependent on Smad signaling or Smad-independent other signaling pathways. The aim of the study was to clarify the involvement of Smad signaling and to investigate the redundancy of Smad2 and Smad3 on various TGF-b-mediated regulation of gene expression in CD4+ T cells. We used microarrays to detail the global program of gene expression regulated by TGF-b in CD4+ T cells, and identified distinct classes of up/down-regulated genes which are dependent on or independent of TGF-b-Smad signaling. Most of genes regulated by TGF-b were redundantly dependent on Smad2 and Smad3, including Foxp3 and IL-2. In addition, some genes were sufficiently regulated via Smad2 or Smad3 signaling alone. In contrast, TGF-b-mediated RORgt induction was independent of Smad signaling. CD4+CD25-CD44loCD62Lhi T cells (naive) were isolated from the spleens in wild-type (WT), T cell-specific Smad2 conditional knockout (Smad2KO or Smad2del/del), Smad3 knockout (Smad3KO or Smad3-/-) or Smad2del/delSmad3+/- mice by using a BD FACS ariaTM cell sorter (BD Bioscience) (purity: >98%). Freshly purified cells were then stimulated with anti-TCR stimuli in the absence or presence of TGF-b for 24 hr, respectively. A complete and precise experimental procedure is given in the "treatment protocol". It was very difficult to obtain the enough number of CD4+CD25-CD44loCD62Lhi naive T cells from Smad2del/delSmad3-/- mice because alomost all of CD4+ T cells were activated in Smad2del/delSmad3-/- mice. We confirmed that the several known Smad-regulated genes were almost out of control in Smad2del/delSmad3+/- CD4+ T cells by using quantitative RT-PCR. Furthermore, previous studies have reported the similar results in other cell types deficit in two alleles of Smad2 and one allele of Smad3. For these reasons, we substituted Smad2del/delSmad3+/- naive T cells for Smad2/3-deficient naive T cells. Cells were quickly collected 24 hr after culture for RNA extraction and hybridization on Affymetrix microarrays.

Project description:Cellular binary fate decisions require the progeny to silence genes associated with the alternative fate. The major subsets of alpha:beta T cells have been extensively studied as a model system for fate decisions. While the transcription factor RUNX3 is required for the initiation of Cd4 silencing in CD8 T cell progenitors, it is not required to maintain the silencing of Cd4 and other helper T lineage genes. The other runt domain containing protein, RUNX1, silences Cd4 in an earlier T cell progenitor, but this silencing is reversed whereas the gene silencing after RUNX3 expression is not reverse. Therefore, we hypothesized that RUNX3 and not RUNX1 recruits other factors that maintains the silencing of helper T lineage genes in CD8 T cells. To this end, we performed a proteomics screen of RUNX1 and RUNX3 to determine candidate silencing factors.

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:TGF-beta signaling in neural crest cells is required for normal craniofacial development. This signaling can be transduced via TGF-beta type I receptors (TGFbRI) using Smad-dependent or Smad independent signaling pathways. We used microarrays to identify TGF-beta-responsive genes that are dependent either on TGFbRI kinase, Tak1 kinase or both. Primary palatal mesenchymal cell cultures were established. Cultured cells were stimulated with TGF-beta2 in the presence or absence of TGFbRI kinase and Tak1 kinase inhibitors. Unstimulated cells were used as controls. Total RNAs were isolated and hybridized on Affymetrix microarrays.
