    Vitamin A supplements, routine immunization, and the subsequent risk of Plasmodium infection among children under 5 years in sub-Saharan Africa

    Maria-Graciela Hollm-Delgado et al.
    An analysis of national survey data shows that vitamin A might protect against malaria infection, an effect potentially modified by seasonality, and that no routine vaccinations were linked to parasitemia, though BCG vaccination was associated with PfHRP-2 antigenemia.

    A vitamin-B2-sensing mechanism that regulates gut protease activity to impact animal’s food behavior and growth

    Bin Qi et al.
    The availability of an essential dietary micronutrient is evaluated by an intestinal signaling system that in turn regulates food-uptake and response behaviors by modulating protease expression.
    1. Neuroscience

    Modulation of dopamine D1 receptors via histamine H3 receptors is a novel therapeutic target for Huntington's disease

    David Moreno-Delgado et al.
    Progression of Huntington's disease can be slowed by altering dopamine signalling through the Dopamine 1 receptor - Histamine 3 receptor heteromer.

    Targeting a cell surface vitamin D receptor on tumor-associated macrophages in triple-negative breast cancer

    Fernanda I Staquicini et al.
    A peptide motif targeting tumor-infiltrating macrophage in triple-negative breast cancer delays tumor growth and favors an antitumor immune response.

    Heparin-binding motif mutations of human diamine oxidase allow the development of a first-in-class histamine-degrading biopharmaceutical

    Elisabeth Gludovacz et al.
    Because heparin-binding motif mutations of human diamine oxidase (hDAO) block cellular uptake and strongly decrease clearance in vivo, modified recombinant hDAO might be a good candidate for the treatment of symptoms induced by excessive endogenous histamine release.
    1. Neuroscience

    The carcinine transporter CarT is required in Drosophila photoreceptor neurons to sustain histamine recycling

    Drew Stenesen et al.
    Fly vision depends on a member of the SLC22 transporter family for recycling the histamine neurotransmitter following its uptake by glia and its modification into the transport metabolite carcinine.

    GluN2B-containing NMDA receptors regulate depression-like behavior and are critical for the rapid antidepressant actions of ketamine

    Oliver H Miller et al.
    The rapid antidepressant actions of low dose ketamine occur through the direct relief of suppression of protein synthesis via antagonism of a subset of NMDA receptors containing the GluN2B subunit.
    1. Neuroscience

    Attenuated dopamine signaling after aversive learning is restored by ketamine to rescue escape actions

    Mingzheng Wu et al.
    Interconnected ventral tegmental area and medial prefrontal cortex circuits causally link dopamine dynamics, aversive learning, and the effects of a promising rapidly acting antidepressant ketamine.
    1. Neuroscience

    All-trans retinoic acid induces synaptic plasticity in human cortical neurons

    Maximilian Lenz et al.
    The vitamin A derivative, all-trans retinoic acid, induces protein-synthesis-dependent synaptic plasticity in the human brain.
    1. Neuroscience

    A circuit mechanism for decision-making biases and NMDA receptor hypofunction

    Sean Edward Cavanagh et al.
    Ketamine, an NMDA receptor antagonist and experimental model for schizophrenia, produces decision-making deficits in monkeys, which are predicted by a lowering of cortical excitation-inhibition balance in a spiking circuit model.
