Insulin/IGF signaling in Drosophila and other insects: factors that regulate production, release and post-release action of the insulin-like peptides

Abstract: Insulin, insulin-like growth factors (IGFs) and insulin-like peptides (ILPs) are important regulators of metabolism, growth, reproduction and lifespan, and mechanisms of insulin/IGF signaling (IIS) have been well conserved over evolution. In insects, between one and 38 ILPs have been identified in each species. Relatively few insect species have been investigated in depth with respect to ILP functions, and therefore we focus mainly on the well-studied fruitfly Drosophila melanogaster. In Drosophila eight ILPs … Show more

“…Alternatively, Tsl may act to influence the activity of the dILPs, which in turn regulate systemic insulin signalling. There are two main tissues that are known to regulate dILP activity (for a complete review of the regulation of dILP production and secretion see Nassel & Vanden Broeck 2016). One is the fat body, which produces and releases important regulators of dILP secretion in response to intracellular nutrient levels ( Fig.…”

“…L'étude des nombreux mutants de la voie du récepteur de l'insuline chez la drosophile a clairement établi l'importance de ce mécanisme hormonal dans le contrôle de la croissance et du métabo-lisme en fonction des conditions environnementales [6]. La notion de contrôle de la taille des organes par des mécanismes intrinsèques provient d'expériences de transplantation de bourgeons de membres entre des espèces de salamandres du genre Ambystoma de différentes tailles [7,8].…”

“…Contrairement aux autres Dilp (Dilp1-7), qui promeuvent la croissance en induisant une signalisation via le récepteur de l'insuline InR, Dilp8 inhibe la croissance via son récepteur Lgr3. Cette signalisation particulière impliquant Lgr3 explique le rôle physiologique très différent de Dilp8 et notamment son implication dans la coordination de la croissance entres organes [6].…”
