Description
Differentiation events contribute to cellular heterogeneity within tumors and influence disease progression and response to therapy. Here we dissect the mechanisms controlling intratumoral heterogeneity within basal-like breast cancers. We show that cancer cells can transition between a differentiation state related to that of normal luminal progenitors and a state closer to that of mature luminal cells, and that this occurs through asymmetric cell divisions. The Polycomb factor EZH2 and the Notch pathway act to increase the rates of symmetric divisions that produce progenitor-like cells, while the FOXA1 transcription factor promotes asymmetric divisions that reduce the numbers of such cells. Through functional screening, we identified a group of regulators that control cancer cell differentiation state and the relative proportions of tumor cell subpopulations. Our findings highlight the regulation of asymmetric cell divisions as a mechanism controlling intratumoral heterogeneity, and identify molecular pathways that control breast cancer cellular composition. Overall design: Expression profiles of HCC70 cells expressing shRNAs targeting regulatory factors that influence basal-like cancer cell population composition

Description
Antibiotic-treated (ABX) mice exhibit an impaired innate and adaptive antiviral immune response and substantially delayed viral clearance following exposure to systemic LCMV or mucosal influenza virus. Genome-wide transcriptional profiling of macrophages isolated from ABX mice revealed decreased expression of genes associated with antiviral immunity. Moreover, macrophages from ABX mice exhibited defective responses to type I and type II IFNs and impaired capacity to limit viral replication. Collectively, these data indicate that commensal-derived signals provide tonic immune stimulation that establishes the activation threshold of the innate immune system required for optimal antiviral immunity.

Description
To examine whether the BPA-induced morphological alterations of the fetal mouse mammary glands are a) associated with changes in mRNA expression reflecting estrogenic actions and/or b) dependent on the estrogen receptor (ER), we compared the transcriptomal effects of BPA and the steroidal estrogen ethinylestradiol (EE2) on fetal mammary tissues of wild type and ER knock-out mice.

Description
Interleukin (IL)-2 is a pleiotropic cytokine that is necessary to prevent chronic inflammation in the gastrointestinal tract. The protective effects of IL-2 involve the generation, maintenance and function of regulatory T cells (Tregs), and low-dose IL-2 has emerged as a potential therapeutic strategy in inflammatory bowel disease (IBD) patients. However, the cellular and molecular pathways that control the production of IL-2 in the context of intestinal health are undefined. Here we identify that IL-2 is acutely required to maintain Tregs and immunologic homeostasis throughout the gastrointestinal tract. Strikingly, lineage-specific deletion of IL-2 in T cells could recapitulate these phenotypes in the large intestine, but not in the small intestine. Unbiased analyses revealed that group 3 innate lymphoid cells (ILC3) are the dominant cellular source of IL-2 in the small intestine, which is selectively induced by IL-1ß. Macrophages produce IL-1ß in the small intestine and activation of this pathway involves MyD88- and Nod2-dependent sensing of the microbiota. Loss-of-function studies defined that ILC3-derived IL-2 is essential to maintain Tregs, immunologic homeostasis and oral tolerance to dietary antigens uniquely in the small intestine. Furthermore, ILC3 production of IL-2 was significantly reduced in the small intestine of Crohn's disease patients, and this correlated with diminished Tregs. Collectively, these results reveal a previously unappreciated pathway whereby a microbiota- and IL-1ß-dependent axis promotes ILC3 production of IL-2 to orchestrate immune regulation in the small intestine. Overall design: RNAs of ILC3s or CD4+ T cells were respectively sorted as CD45+CD3-ROR?tGFP+CD127+ or CD45+CD3+CD4+ from 3 wild type mice.

Description
Innate lymphoid cells (ILCs) are a recently recognized heterogenous group of immune cells that are critical in orchestrating immunity and inflammation in the intestine, but whether ILCs influence immune responses or tissue homeostasis at other mucosal sites remains poorly characterized. Here we identify a population of lung-resident ILCs in mice and humans that expressed the alloantigen Thy-1 (CD90), interleukin 2 (IL-2) receptor a-chain (CD25), IL-7 receptor a-chain (CD127) and the IL-33 receptor subunit T1-ST2. Notably, mouse ILCs accumulated in the lung after infection with influenza virus, and depletion of ILCs resulted in loss of airway epithelial integrity, diminished lung function and impaired airway remodeling. These defects were restored by administration of the lung ILC product amphiregulin. Collectively, our results demonstrate a critical role for lung ILCs in restoring airway epithelial integrity and tissue homeostasis after infection with influenza virus.
