    Tyramine and its Amtyr1 receptor modulate attention in honey bees (Apis mellifera)

    Joseph S Latshaw, Reece E Mazade ... Brian Smith
    Genetic variation in a biogenic amines receptor underlies a means of gain control for nonassociative learning and hence an important form of attention that is the basis for tradeoffs in foraging in a social collective.

    Removal of inhibition uncovers latent movement potential during preparation

    Uday K Jagadisan, Neeraj J Gandhi
    Non-invasive disinhibition of the oculomotor system shows that ongoing preparatory activity in the superior colliculus has movement-generating potential and need not rise to threshold in order to produce a saccade.

    Dopamine neuron dependent behaviors mediated by glutamate cotransmission

    Susana Mingote, Nao Chuhma ... Stephen Rayport
    The conditional reduction of glutaminase in mouse dopamine neurons selectively attenuates glutamate cotransmission at phasic frequencies, revealing the role of dopamine neuron glutamate cotransmission in the attribution of motivational salience.

    Hydrogen sulfide blocks HIV rebound by maintaining mitochondrial bioenergetics and redox homeostasis

    Virender Kumar Pal, Ragini Agrawal ... Amit Singh
    A gaseous signaling molecule hydrogen sulfide stimulates mitochondrial bioenergetics, maintains glutathione redox poise, and suppresses ROS to subvert viral rebound in latently infected CD4+ T cells from HIV subjects.

    Distinct chromatin functional states correlate with HIV latency reactivation in infected primary CD4+ T cells

    Emilie Battivelli, Matthew S Dahabieh ... Eric Verdin
    Analysis of HIV integration sites from induced and non-induced latently infected populations reveals the role of genomic localization and chromatin context in the fate of HIV-1 infection and the reversal of viral latency.

    Hidden long-range memories of growth and cycle speed correlate cell cycles in lineage trees

    Erika E Kuchen, Nils B Becker ... Thomas Höfer
    The combination of statistical inference and perturbation experiments reveals that trans-generational inheritance of cell size and cell-cycle speed, coupled through a minimum-size checkpoint, shapes paradoxical cell-cycle correlations in lineage trees.

    Release of human cytomegalovirus from latency by a KAP1/TRIM28 phosphorylation switch

    Benjamin Rauwel, Suk Min Jang ... Didier Trono
    Inactivation of KAP1 by mTOR-mediated phosphorylation releases human cytomegalovirus from latency, and has the potential to be used as a therapy to purge the virus from transplant organs.

    Tgfb3 collaborates with PP2A and notch signaling pathways to inhibit retina regeneration

    Mi-Sun Lee, Jin Wan, Daniel Goldman
    Tgfb3 inhibits Muller glial cell reprogramming and drives Muller cell quiescence in the injured zebrafish retina, thereby inhibiting retina regeneration.

    Neuronal hyperexcitability is a DLK-dependent trigger of herpes simplex virus reactivation that can be induced by IL-1

    Sean R Cuddy, Austin R Schinlever ... Anna R Cliffe
    Herpes simplex virus reactivates from a latent infection when neurons become hyperexcitable in response to an inflammatory cytokine known to be released during fever and stress.

    Herpesviral lytic gene functions render the viral genome susceptible to novel editing by CRISPR/Cas9

    Hyung Suk Oh, Werner M Neuhausser ... David M Knipe
    CRISPR genome editing technology can efficiently introduce mutations into lytic and latent HSV genomes to block lytic replication and reactivation of latent herpes simplex virus genome though differential mechanisms.
