    Brain endothelial cell TRPA1 channels initiate neurovascular coupling

    Pratish Thakore et al.

    Endothelial pannexin 1–TRPV4 channel signaling lowers pulmonary arterial pressure in mice

    Zdravka Daneva et al.
    Endothelial pannexin 1-P2Y2 purinergic receptor-TRPV4 channel signaling, facilitated by caveolin-1, is a novel pathway for lowering pulmonary arterial pressure.

    Capillary pericytes mediate coronary no-reflow after myocardial ischaemia

    Fergus M O'Farrell et al.
    Lack of reperfusion of cardiac capillaries, when an upstream artery is unblocked following heart attack, reflects contractile pericytes constricting capillaries and preventing blood flow, implying that cardiac pericytes are a therapeutic target for treating cardiac ischaemia.

    Parabrachial opioidergic projections to preoptic hypothalamus mediate behavioral and physiological thermal defenses

    Aaron J Norris et al.
    Warm-activated parabrachial neurons contain overlapping dynorphin and enkephalin expressing subpopulations, project to preoptic hypothalamus, and mediate behavioral and physiological thermal defenses behaviors.

    Estrogen receptor alpha in the brain mediates tamoxifen-induced changes in physiology in mice

    Zhi Zhang et al.
    Estrogen receptor alpha in the hypothalamus is required for the effects of chronic tamoxifen treament on gene expression, thermoregulation, bone, and movement in mice.

    Vascular control of the CO2/H+-dependent drive to breathe

    Colin M Cleary et al.
    Understanding how loss of CO2/H+ vascular reactivity affects respiratory control may facilitate development of treatments for breathing problems in this population.

    Thioredoxin shapes the C. elegans sensory response to Pseudomonas produced nitric oxide

    Yingsong Hao et al.
    C. elegans utilizes bacterially produced nitric oxide as a sensory cue to elicit avoidance of pathogenic bacteria.

    Cardiovascular adaptation to hypoxia and the role of peripheral resistance

    Andrew S Cowburn et al.
    Radiotelemetric and genetic studies of peripheral tissue response show that a peripheral tissue can dynamically alter cardiovascular adaptation to changes in environmental oxygen.
