Description
Expression from CD133+ cells isolated from adult human exocrine tissue was compared to a CD133-depleted cell population Overall design: Islet-depleted exocrine tissue from three independent adult human cadaveric pancreata were cultured for four days in Miami media 1A. Following trypsinization, cells were isolated using anti-CD133 immunomagnetic beads to >95% CD133+. CD133-negative cells were further depleted of CD133+ cells to <1% CD133+.

Description
Airway epithelium is the initial point of host-pathogen interaction in Pseudomonas aeruginosa infection, an important pathogen in cystic fibrosis and nosocomial pneumonia. We used global gene expression analysis to determine airway epithelial transcriptional responses dependent on matrilysin (MMP-7) and stromelysin-2 (MMP-10), two matrix metalloproteinases induced by acute P. aeruginosa pulmonary infection. Extraction of Differential Gene Expression (EDGE) analysis of gene expression changes in P. aeruginosa infected organotypic tracheal epithelial cell cultures from wildtype, Mmp7-/-, and Mmp10-/- mice identified 2,089 matrilysin-dependent and 1,628 stromelysin-2-dependent genes that were differentially expressed. Key node network analysis showed that these MMPs controlled distinct gene expression programs involved in proliferation, cell death, immune responses, and signal transduction, among other host defense processes. Our results demonstrate discrete roles for these MMPs in regulating epithelial responses to pseudomonas infection and show that a global genomics strategy can be used to assess MMP function.

Description
Translational profiling methodologies enable the systematic characterization of cell types in complex tissues such as the mammalian brain, where neuronal isolation is exceptionally difficult. Here, we report a versatile strategy to profile CNS cell types in a spatiotemporally-restricted fashion by engineering a Cre-dependent adeno-associated virus expressing an EGFP-tagged ribosomal protein (AAV-FLEX-EGFPL10a) to access translating mRNAs by TRAP. We demonstrate the utility of this AAV to target a variety of genetically and anatomically defined neural populations expressing Cre recombinase and illustrate the ability of this viral TRAP (vTRAP) approach to recapitulate the molecular profiles obtained by bacTRAP in corticothalamic neurons across multiple serotypes. Furthermore, spatially restricting AAV injections enabled the elucidation of regional differences in gene expression within this cell type. Taken together, these results establish the broad applicability of the vTRAP strategy for the molecular dissection of any CNS or peripheral cell type that can be engineered to express Cre. Overall design: Polysome-bound mRNAs from TRAP IPs were compared to whole tissue mRNAs. Data was collected from MCH neurons in hypothalamus using vTRAP, cortical layer 6 Ntsr1 neurons using vTRAP, and cortical layer 6 Ntsr1 neurons using bacTRAP. We include vTRAP data from three AAV serotypes for the cortical Ntsr1 cells. We collected three replicates for IP and inputs for vTRAP experiments, while bacTRAP data was collected in duplicate.

Description
The colonic lamina propria contains a distinct population of Foxp3+ T regulatory cells (Tregs) that modulate responses to commensal microbes. Analysis of gene expression revealed that the transcriptome of colonic Tregs is distinct from splenic and other tissue Tregs. Ror and Helios in colonic Tregs mark distinct populations: Ror+Helios- or Ror-Helios+ Tregs. We uncovered an unanticipated role for Ror, a transcription factor generally considered to be antagonistic to Foxp3. Ror in colonic Tregs accounts for a small but specific part of the colon-specific Treg signature.

Description
The polarization of macrophages into an anti-inflammatory or regulatory phenotype plays an important role in resolving inflammation. PGE2 regulates macrophage polarization via a PKA dependent pathway. PKA phosphorylates SIKs, inhibiting their ability to phosphorylate CRTC3 in cells. This in turn allows CRTC3 to translocate to the nucleus where it acts as a co-activator with the transcription factor CREB to induce IL-10 transcription. In line with this we find that either genetic or pharmacological inhibition of SIKs mimics the effect of PGE2 on IL-10 production.

Description
CD8 T cells play an importart role in adaptive immunity to intracellular pathogens. Nave CD8 T cells , that have not encountered antigen previously can be identified by virtue of their distinct phenotype. Upon antigenic encounter, they proliferate rapidly and undergo massive reprograming to differentiate to cytotoxic T lymphocytes. The yellow fever live virus vaccine (YF-17D) provides a model primary acute viral infection that can be used to follow this response.Here we characterize the resting, non-activated naive CD8 T cells in nine healthy adults and YF-specific CD8 T cells elicited in response to YF-17D vaccination from the same donors during the effector (2 weeks after vaccination) and memory (5-8 months later) stages.

Description
These 14 samples originate from peripheral blood mononuclear cells (PBMC) from donors at different times after they were vaccinated with the YF-17D vaccine. Overall design: 10,000 to 100,000 tetramer+ CD8 T cells specific for the NS4B-214 epitope in YFV-17D were purified by flow cytometry based sorting, from 8 vaccinees. Total Naive (CD45RA+ CD8+) CD8 t cells were also sorted from these donors. Subsets were defined based on the time after vaccination. The subsets (cell types) include: Naive CD8 T cells (n=6); YFV-specific Effector CD8 T cells (day 14 after vaccination, n =3) and YFV-specific long term memory CD8 T cells (4 to 12 years after vaccination, n=5).
