Affymetrix Mouse Genome 430 2.0 Array (mouse4302)
Description
Development of LNA gapmers, antisense oligonucleotides used for efficient inhibition of target RNA expression, is limited by non-target mediated hepatotoxicity issues. In the present study, we investigated hepatic transcription profiles of mice receiving non-toxic and toxic LNA gapmers after a single and repeat administration.

Description
Bud endodormancy induction response of two genotypes (Seyval a hybrid white wine grape and V. riparia, PI588259 a native north american species) was compared under long (15h) and short (13h) photoperiod. Three separate replicates (5 plants/replicate) were treated to generate paradormant (LD) and same aged endodormancy-induced (SD) buds for transcriptomic, proteomic and metabolomic analysis. Potted, spur-pruned two to six-year-old vines were removed from cold storage (Seyval 3-19-07; V. riparia 3/26/07) and grown under a LD (15 h) at 25/20 + 3C day/night temperatures (D/N). When vines reached 12-15 nodes (3-25-07) they were randomized into LD or SD treatments with 25/20 + 3C D/N in climate controlled greenhouses with automated photoperiod system (VRE Greenhouse Systems). Three replications (5 vines/replication) were harvested between 5/07-6/07 and then again in 5/08-6/08 for a total of six replications. All treatments are repeated at the same time every year and harvested at the same time of day each year to minimize biological noise. At 1, 3, 7, 14, 21, 28 and 42 days of LD and SD treatment, buds were harvested from nodes 3 to 12 of each separate replicate, immediately frozen in liquid nitrogen, and placed at -80C for future RNA, protein and metabolite extraction. These time points encompass early reversible phases as well as key time points during transition to irreversible endodormancy development. After photoperiod treatments and bud harvests, all pruned vines were returned to LD and monitored for bud endodormancy. The endodormant vines were identified after 28 days and moved to cold storage. The nondormant vines were allowed to grow again and induced into dormancy at a later date.

- Affymetrix Mouse Gene 1.0 ST Array (mogene10st)
Description
Co-stimulatory molecules of the CD28 family on T lymphocytes integrate cues from innate immune system sensors, and modulate activation responses in conventional CD4+ T cells (Tconv) and their FoxP3+ regulatory counterparts (Treg). To better understand how costimulatory and co-inhibitory signals might be integrated, we profiled the changes in gene expression elicited in the hours and days after engagement of Treg and Tconv by anti-CD3 and either anti-CD28, -CTLA4, -ICOS, -PD1, -BTLA or -CD80.

Description
We report transcriptional characterization of skeletal muscle macrophage subsets in normal and injured muscle after intramuscular injection with cardiotoxin. We profiled transcriptional differences in macrophage subsets from mice depleted of Treg cells using Foxp3-DTR mice. We uncovered an IFN-g-centered regulatory loop, in which Treg cells inhibit NK and T cells to control macrophage accumulation and phenotype during muscle regeneration.

Description
This study was performed to understand what controls the aggressivity of the pancreatic infiltrate during type-I diabetes development. We used the BDC2.5 transgenic mouse model. Samples were obtained at the age of onset of insultis. Depending on their genetic background, mice transgenic for the BDC2.5 T cell receptor present very different forms of insulitis. The NOD genetic background leads to a benign insulitis whereas the C57Bl/6-H2g7/g7 leads to an aggressive insulitis. We first studied how antigen-specific T cells are affected by these differences by obtaining the transcriptional profiles of BDC2.5 T cells from pancreas and pancreatic lymph nodes. We also compared the gene expression profiles of the entire leukocyte population present in the pancreatic lesion.

Description
Three innate (B1-B, NKT, CD8aaT cells) and adaptive (B2-B, CD4T, CD8abT cells) cell-types were sorted by FACS. Three biological replicates for NKT, CD4T, CD8aaT, CD8abT cells and two biological replicates for B1 and B2 cells were generated and the expression profiles were determined using Affymetrix Mu74Av2 chip. Comparisons between the sample groups allow the identification of genes differentially expressed between the innate and adaptive cell-types.

Description
The aim of this study was to determine the effect of transgenic Aire expression on the transcriptional profile of a tissue that normally does not express Aire: pancreatic islets. The transcriptional profile of transgenic RIP-Aire27 islets was compared to non-transgenic littermate islets as well as to archival NOD thymic medullary epithelial cells (MEC) data. All data were from non-obese diabetic (NOD) mice

NextSeq 500
Description
The first T cells to arrive in the liver were mostly T regulatory (Treg) cells and metabolically active, highly proliferative T conventional (Tconv) cells. The Tconv cells had unusually high expression of PD-1 and the IL-33 receptor, ST2. As these PD-1+ Tconv cells accumulated in the tissue, they gradually lost their expression of ST2, ceased to proliferate and acquired an anergic phenotype. Overall design: Gene expression profiles of flow cytometry sorted DAPI negative CD45 positive TCRb positive CD4 positive Foxp3 negative cells from liver of 5- and 10-day-old B6.Aire-KO mice
Publication Title
T cell anergy in perinatal mice is promoted by T reg cells and prevented by IL-33.
