    Claudin-5 is a component of tight junctions and has important roles in mediating the permeability of the blood-brain barrier. Campbell and co-workers administer short interfering RNA against claudin-5 in a model of brain injury, finding that it enhances water movement from the brain to the blood and alleviates swelling.

    Lung injury initiates a series of wound-healing responses, which if unregulated, can lead to fibrosis. Liet al. show that the deubquitinase CYLD has a key role in the prevention of fibrosis by inhibiting transforming growth factor β-signalling through the direct deubiquitination of the protein kinase Akt.

    Hyperuricemia, or gout, is thought to arise either from urate overproduction or from decreased renal excretion of urate. Ichidaet al. show that the extra-renal excretion of urate also has a role in the pathogenesis of hyperuricemia, and propose a new classification for patients with this disease.

    Bioassays are the standard way to measure prion infectivity titres, but can be time-consuming. In this study, bioassays are compared with a modified version of the protein misfolding cyclic amplification technique with beads (PMCAb), demonstrating that PMCAb can be more precise and faster than bioassays.

    It is unclear whether pathogens can advantageously exploit the host's immune response. UsingCandida albicans, the authors show that host IL-17A binds to the fungi and induces nutrient starvation and autophagy, which eventually leads to enhanced biofilm formation and resistance to the hosts' defence.

    β-Catenin can be oncogenic but finding inhibitors has been a challenge. Here, five compounds are identified, which attenuate transcriptional β-catenin outputs in colorectal cancer cells, and the response to one of them is shown to require an intrinsically labile α-helix next to the BCL9-binding site in β-catenin.

    Molecular factors, regulating the expression of specific glycolytic enzymes that favour biosynthetic processes, have remained unknown. Panasyuket al. identify PPARγ as a novel transcription factor turning on pyruvate kinase M2 and hexokinase 2, which are frequently upregulated in pathophysiological growth.

    Spatial epidemiology studies identify malaria hotspots, which sustain transmission and so could be targeted by control programmes. This study uses spatial data on larval sites and malaria episodes to show that transmission can be disrupted by targeting vector breeding sites close to and downwind of malaria hotspots.

    The signalling cascade involved in lung ischaemia–reperfusion-induced oedema is poorly understood. Using knockout mice, Weissmannet al. propose a model in which reactive oxygen species production by endothelial NOX2 leads to phospholipase C-γ activation, DAG kinase inhibition and subsequent TRPC6 activation.

    In vertebrates parasite-mediated selection is thought to maintain polymorphism in MHC genes where specific resistance MHC alleles increase under emerging selection. Here, experimental evidence is shown from six stickleback fish populations that varying parasite selection helps maintain MHC polymorphism.

    The processes that regulate melanoblast migration during development are also thought to be involved in melanoma metastasis. Here, Prex1 null mice are shown to have a melanoblast migration defect and, when crossed to a mouse model of melanoma, are resistant to metastasis, suggesting a role for Prex1 in metastatic melanoma.

    Erythropoietin circulates in the blood and is essential for erythropoiesis but its role in metabolic homeostasis has not been examined. Tenget al. show that when the erythropoietin receptor is only expressed in erthyroid cells, mice develop obesity and insulin resistance, suggesting that the receptor has a key role in fat mass accumulation.

    During cell division, a cytoplasmic bridge—the midbody—forms between the nascent daughter cells, but it has been unclear under which conditions this is retained by a daughter cell or released. Now, Ettinger and colleagues show that midbody-release occurs more frequently in stem cells compared with cancer cells.

    Cellular senescence is characterized by the cessation of cell growth and the expression of the p16 protein. In this study, inhibition or loss of p300, a histone acetyltransferase, is shown to result in senescence that occurs independently of p16 and is associated with histone hypoacetylation and altered replication timing.
