Description
Previous reports have defined three subsets of mouse NK cells on the basis of the expression of CD27 and CD11b. The developmental relationship between these subsets was unclear. To address this issue, we evaluated the overall proximity between mouse NK cell subsets defined by CD27 and CD11b expression using pangenomic gene expression profiling. The results suggest that CD27+CD11b-, CD27+CD11b+ and CD27-CD11b+ correspond to three different intermediates stages of NK cell development.

Description
The activity of the endoribonuclease Dicer is crucial to produce the mature form of most microRNAs (miRNAs). Recent studies indicate that lack of miRNAs in different neuronal types results in a range of anatomical and behavioural phenotypes. In the present study we aimed to investigate the developmental and metabolic consequences of miRNA ablation in hypothalamic POMC neurons studying mice with a conditional deletion of Dicer in this population of neurons (POMCDicerKO). These mice exhibited a progressive obese phenotype characterized by hyperphagia, increased adiposity, hyperleptinemia, defective glucose metabolism and alterations in the pituitary-adrenal axis. The development of the obese phenotype was paralleled by a POMC neuron degenerative process that was complete by 6 weeks of age. Furthermore, immunohistochemistry and gene expression studies in control C57Bl/6 adult mice showed that Dicer was expressed in relevant hypothalamic areas and neurons implicated in energy balance, and that its expression was regulated by nutrient availability. Collectively, our results highlight a crucial role for miRNAs in POMC neuron survival and the consequent development of neurodegenerative obesity.

Description
Transcriptome analysis comparing naive, protective and non-protective spleen memory CD8 T lymphocytes were conducted to identify key functions associated with memory CD8-mediated immune protection. Memory CD8 T cells generated in response to influenza or vaccinia infection (Flu-memory and VV-memory) were compared to inflammatory memory cells (TIM) that were generated by peptide in inflammatory context. Gene expression analysis was performed on quiescent and re-stimulated CD8 T cells.

We analyzed the impact of the genetic background during experimental passive non-accelerated anti-glomerular basement membrane glomerulonephritis (anti-GBM-GN) (an equivalent to nephrotoxic nephritis) in two different mouse genetic backgrounds (C57BL6/J vs 129S2svPAS/crl).

Description
Notch3 is a transmembrane receptor which is critically important for the structure and myogenic response of distal arteries, particularly cerebral arteries. After activation of the receptor, the intracellular domain translocates in the nucleus to activate target genes transcription.
Publication Title
Transcriptome analysis for Notch3 target genes identifies Grip2 as a novel regulator of myogenic response in the cerebrovasculature.

Description
The newly identified claudin-low subtype of cancer is believed to represent the most primitive breast malignancies, having arisen from transformation of an early epithelial precursor with inherent stemness properties and metaplastic features. Challenging this hypothesis, we show both in vitro and in vivo that transcription factors inducing epithelial-mesenchymal transition can drive the development of claudin-low tumors from differentiated mammary epithelial cells, by playing a dual role in cell transformation and dedifferentiation.
