    Paths and pathways that generate cell-type heterogeneity and developmental progression in hematopoiesis

    Juliet R Girard, Lauren M Goins ... Utpal Banerjee
    A combination of mRNA sequencing and genetic analysis reveals mechanisms that govern the development of distinct differentiated blood cell types from hematopoietic progenitors.

    ACC neural ensemble dynamics are structured by strategy prevalence

    Mikhail Proskurin, Maxim Manakov, Alla Karpova
    Anterior Cingulate Cortex displays robust tracking during strategy execution of a summary statistic for that strategy in recent behavioral history, suggesting a role for this brain region in estimating which actions promote the occurrence of events in the environment.

    Effects of clozapine-N-oxide and compound 21 on sleep in laboratory mice

    Janine Traut, Jose Prius Mengual ... Lukas B Krone
    The two most commonly used chemogenetic actuators, clozapine-N-oxide and compound 21, similarly modulate sleep in wild-type laboratory mice indicating that even designer drugs which do not convert to clozapine can elicit behavioural effects and require adequate controls.

    IFNγ induces epigenetic programming of human T-bethi B cells and promotes TLR7/8 and IL-21 induced differentiation

    Esther Zumaquero, Sara L Stone ... Frances E Lund
    IFNγ increases the responsiveness of human B cells to IL-2, TLR7/8 and IL-21 signals and therefore enhances antibody production in inflammatory settings associated with autoimmune or chronic disease.

    Cellular mechanisms underlying central sensitization in a mouse model of chronic muscle pain

    Yu-Ling Lin, Zhu-Sen Yang ... Cheng-Chang Lien
    Maladaptive changes of pro-nociceptive neurons in the central nucleus of the amygdala drive the chronification of muscle pain and comorbid affective behaviors.

    BiteOscope, an open platform to study mosquito biting behavior

    Felix JH Hol, Louis Lambrechts, Manu Prakash
    A new tool to visualize blood-feeding mosquitoes in high resolution and quantitatively characterize their behavior sheds light on contact-dependent sensing and blood-feeding dynamics of several medically relevant mosquito species.

    Stress resets ancestral heritable small RNA responses

    Leah Houri-Zeevi, Guy Teichman ... Oded Rechavi
    Various types of stress reset heritable small RNA responses through the function of the p38 MAPK pathway, the transcription factor SKN-1/Nrf2, and the MET-2/SETDB1 putative histone methyltransferase.

    Atoh1-dependent rhombic lip neurons are required for temporal delay between independent respiratory oscillators in embryonic mice

    Srinivasan Tupal, Wei-Hsiang Huang ... Paul A Gray
    The rhythmic patterns of activity that underlie breathing are generated and coordinated by distinct populations of neurons within the brainstem.

    Heparan sulfates are critical regulators of the inhibitory megakaryocyte-platelet receptor G6b-B

    Timo Vögtle, Sumana Sharma ... Yotis A Senis
    Heparan sulfates in the vessel wall bind and regulate signaling from the megakaryocyte/platelet-specific inhibitory receptor G6b-B, a critical regulator of platelet homeostasis.

    Bacterial lifestyle switch in response to algal metabolites

    Noa Barak-Gavish, Bareket Dassa ... Assaf Vardi
    Opportunistic bacteria modulate their lifestyle from coexistence to pathogenicity by perceiving the physiological state of their algal host through sensing of algal secreted metabolites.
