    Insect endosymbiont proliferation is limited by lipid availability

    Jeremy K Herren et al.
    The endosymbiont Spiroplasma can only proliferate if it can acquire sufficient hemolymph lipids from its insect host.

    Endocrine remodelling of the adult intestine sustains reproduction in Drosophila

    Tobias Reiff et al.
    A hormone released after mating acts directly on adult intestinal progenitors and differentiated epithelial cells in Drosophila to change their homeostatic setpoint and maximise fecundity.

    Symbiosis: Protection from within

    Florent Masson, Bruno Lemaitre
    The development of the tsetse fly immune system relies on a cue from an endosymbiotic bacterium called Wigglesworthia.

    Remodeling of whole-body lipid metabolism and a diabetic-like phenotype caused by loss of CDK1 and hepatocyte division

    Jin Rong Ow et al.
    Loss of hepatic Cdk1 leads to oxidative stress, increased fatty acids in blood, and hyperinsulinemia, which resulted in insulin resistance and hepatic steatosis, similar as in diabetes.

    Phosphatidylcholines from Pieris brassicae eggs activate an immune response in Arabidopsis

    Elia Stahl et al.
    Plants detect the presence of phospholipids in eggs from a herbivorous insect and trigger innate immunity.

    Functional genomics of lipid metabolism in the oleaginous yeast Rhodosporidium toruloides

    Samuel T Coradetti et al.
    Using barcoded mutagenesis and a high-throughput genetic screen results in the identification of 150 genes that affect lipid accumulation in a non-model yeast system.

    Serotonin signaling mediates protein valuation and aging

    Jennifer Ro et al.
    Serotonin modulates diet-dependent lifespan in flies.

    Dietary sugar inhibits satiation by decreasing the central processing of sweet taste

    Christina E May et al.
    Taste-dependent satiation, which induces proper cessation of feeding in mammals as well as insects, is weakened by sugar-diet-driven taste impairment in the fruit fly.

    Metabolic stress is a primary pathogenic event in transgenic Caenorhabditis elegans expressing pan-neuronal human amyloid beta

    Emelyne Teo et al.
    Metabolic defects following expression of Aβ1-42 in nematode neurons are partially caused by inactivation of alpha-ketoglutarate dehydrogenase and can be rescued by Metformin.
