    Three-dimensional imaging of vascular development in the mouse epididymis

    Christelle Damon-Soubeyrand, Antonino Bongiovanni ... Joelle Henry-Berger
    The lymphatic and blood network of the mouse epididymis in adulthood and during postnatal ontogeny has been analyzed in detail.

    Accumbens cholinergic interneurons dynamically promote dopamine release and enable motivation

    Ali Mohebi, Val L Collins, Joshua D Berke
    In awake behaving rats, cholinergic interneurons in the nucleus accumbens drive dopamine release via nicotinic receptors, boosting motivation to work.

    ErbB signaling is a potential therapeutic target for vascular lesions with fibrous component

    Suvi Jauhiainen, Henna Ilmonen ... Johanna P Laakkonen
    Experimentation on patient biopsies, cell culture, and xenograft models demonstrates involvement of ErbB signaling and fibroblasts in lesion growth, implying that targeting of both stromal and endothelial cells could be a beneficial treatment strategy for patients with venous lesions.

    Arginase 1 is a key driver of immune suppression in pancreatic cancer

    Rosa E Menjivar, Zeribe C Nwosu ... Marina Pasca di Magliano
    Deletion of Arginase 1 in myeloid cells delays tumor formation in pancreatic cancer.

    Mitotic chromosomes scale to nuclear-cytoplasmic ratio and cell size in Xenopus

    Coral Y Zhou, Bastiaan Dekker ... Rebecca Heald
    A combination of in vivo and in vitro approaches using Xenopus eggs and embryos reveals how dimensions of mitotic chromosomes scale with decreasing cell size and increasing nuclear-cytoplasmic ratio during early embryogenesis.

    Molecular basis of ligand-dependent Nurr1-RXRα activation

    Xiaoyu Yu, Jinsai Shang, Douglas J Kojetin
    Transcriptional activation of the orphan nuclear receptor Nurr1 by ligands targeting its heterodimer partner retinoid X receptor alpha (RXRα) occurs through a nonclassical pharmacological mechanism involving ligand-binding domain protein-protein interaction inhibition.

    The prolactin receptor scaffolds Janus kinase 2 via co-structure formation with phosphoinositide-4,5-bisphosphate

    Raul Araya-Secchi, Katrine Bugge ... Birthe B Kragelund
    The prolactin receptor, Janus kinase 2, and PI(4,5)P2 form a co-structure with the membrane resulting in orientations with different accessibility fixing the disordered juxtamembrane domain of the receptor in an extended structure.

    Prolonged nicotine exposure reduces aversion to the drug in mice by altering nicotinic transmission in the interpeduncular nucleus

    Sarah Mondoloni, Claire Nguyen ... Alexandre Mourot
    Inter-individual variabilities in nicotine aversion are linked with responses of the interpeduncular nucleus to the drug.
    1. Neuroscience

    Are single-peaked tuning curves tuned for speed rather than accuracy?

    Movitz Lenninger, Mikael Skoglund ... Arvind Kumar
    Single-peaked tuning curves found in early sensory areas are more optimized for quick decoding than accuracy, while multi-peaked tuning curves (e.g. grid cells) give higher accuracy but only at longer time scales.

    Tau polarizes an aging transcriptional signature to excitatory neurons and glia

    Timothy Wu, Jennifer M Deger ... Joshua M Shulman
    While tau and aging have highly overlapping differential gene expression signatures, they diverge in the affected cell types, with aging having a wide-ranging impact and tau-triggered changes instead polarized to excitatory neurons and glia.
