Description
Notch signaling is widely implicated in mouse mammary gland development and tumorigenesis. To investigate the effects of acute activation of Notch signaling in the mammary epithelial compartment, we generated bi-transgenic MMTV-rtTA; TetO-NICD1 (MTB/TICNX) mice that conditionally express a constitutively active NOTCH1 intracellular domain (NICD1) construct in the mammary epithelium upon doxycycline administration.

Description
GATA3 is indispensable for the development of all IL-7Ra-expressing innate lymphoid cells (ILCs) and maintenance of type 1 ILCs (ILC1s) and type 2 ILCs (ILC2s). However, the importance of low GATA3 expression in type 3 ILCs (ILC3s) is still elusive. Here, we report that GATA3 regulates homeostasis of ILC3s by controlling IL-7Ra expression. In addition, GATA3 is critical for the development of NKp46+ ILC3 subset partially through regulating the balance between T-bet and ROR?t. Genome-wide analyses indicate that while GATA3 positively regulates CCR6+ and NKp46+ ILC3 subset-specific genes in respective lineages, it negatively regulates CCR6+ ILC3-specific genes in NKp46+ ILC3s. Furthermore, GATA3 regulates IL-22 production in both CCR6+ and NKp46+ ILC3s. Thus, low GATA3 expression is critical for the development and function of ILC3 subsets. Overall design: To identify GATA3 regulated genes in total ILC3s with RNA-Seq; To identify unique genes expressed by CCR6+ ILC3 or NKp46+ ILC3 and GATA3 regulated genes within these two ILC3 subsets with RNA-Seq; To identify GATA3 direct binding sites in ILC3s, ILC2s and Th2 cells with ChIP-Seq.

Description
CD4(+)Foxp3(+) regulatory T (Treg) cells originate primarily from thymic differentiation, but conversion of mature T lymphocytes to Foxp3 positivity can be elicited by several means, including in vitro activation in the presence of TGF-beta. Retinoic acid (RA) increases TGF-beta-induced expression of Foxp3, through unknown molecular mechanisms. We showed here that, rather than enhancing TGF-beta signaling directly in naive CD4(+) T cells, RA negatively regulated an accompanying population of CD4(+) T cells with a CD44(hi) memory and effector phenotype. These memory cells actively inhibited the TGF-beta-induced conversion of naive CD4(+) T cells through the synthesis of a set of cytokines (IL-4, IL-21, IFN-gamma) whose expression was coordinately curtailed by RA. This indirect effect was evident in vivo and required the expression of the RA receptor alpha. Thus, cytokine-producing CD44(hi) cells actively restrain TGF-beta-mediated Foxp3 expression in naive T cells, and this balance can be shifted or fine-tuned by RA.

Description
We performed RNAseq on subpopulations of mammary epithelial cells. We carried out sorting of a gradient of s-SHIP positive cells in the mammary gland (neg, low, and hi for s-SHIP eGFP). High sSHIP-eGFP populations denote a postulated stem cell population, while low and negative represent more differentiated cell types. s-SHIP eGFP hi to negative potentially represents a gradient from stem to more differentiated progeny, respectively, within the basal epithelial compartment. We FACS sorted 3 replicates for each cell type to represent s-SHIP-neg, s-SHIP-low, and s-SHIP-high. Overall design: We FACS sorted 3 replicates for each cell type to represent s-SHIP-neg, s-SHIP-low, and s-SHIP-high, profiling each of these groups using RNA sequencing.

Description
In support of our manuscript investigating the roles of ILCs and T cells in the maintenance of gut hoemostasis, we have performed RNAseq on terminal illeum of mice lacking either all adaptive immune cells (RAG1 -/-), deficient in T cells (TCRalpha -/-), or deficient in T cells but co-housed with wild-type mice and RAG1 -/- mice. Overall design: Tissues from three mice per group were analysed, and the following comparisions were made: RAG1-/- vs. WT C57BL/6 and TCRa-/- co-housed vs TCRa-/- seperately housed. Differential expression genes were identified at 1% FDR using DESeq2.

Description
Life-threatening pulmonary influenza can be caused by inborn errors of type I and III IFN immunity. We report a 5 year-old child with severe pulmonary influenza at 2 years. She is homozygous for a loss-of-function IRF9 allele. Her cells activate gamma-activated factor (GAF) STAT1 homodimers but not interferon-stimulated gene factor 3 (ISGF3) trimers (STAT1/STAT2/IRF9) in response to IFN-a2b. The transcriptome induced by IFN-a2b in the patient's cells is much narrower than that of control cells; however, induction of a subset of interferon-stimulated gene transcripts remains detectable. In vitro, the patient's cells do not control three respiratory viruses, influenza A virus (IAV), parainfluenza virus, and respiratory syncytial virus. These phenotypes are rescued by wild-type IRF9, whereas silencing IRF9 expression in control cells increases viral replication. However, the child has controlled various common viruses in vivo, including respiratory viruses other than IAV. Our findings show that human IRF9- and ISGF3-dependent type I and III IFN responsive pathways are essential for controlling IAV. Overall design: Total of 72 samples, 38 samples from primary fibroblasts and 34 samples from EBV-transformed B cells, were analyzed using paired-end RNA sequence data. Out of 38 samples from primary fibroblasts, 3 control samples are paired with no stimulation vs IFNa2b stimulation. Out of 34 samples from B-cells, 3 control samples are paired with no stimuliion vs IFNa2b stimulation. In addition to healthy control subjects, patients with AR complete STAT1 (STAT1 -/-) or STAT2 (STAT2 -/-) deficiency were analyzed for comparison.
