A proteomic and cytological characterisation of the buff-tailed bumblebee (Bombus terrestris) fat body and haemolymph -An immune perspective
… of the B. terrestris immune system, the fat body (FB) and haemolymph were characterised here using proteomic and cytological methodologies. The FB proteome is highly enriched in metabolic, detoxification and proteostasis processes whereas the haemolymph is enriched in cellular transport …

The Putative Role Of Fatty Acids In The Activation Of Trehalose Synthesis In The Fat Body Of The Cockroach Periplaneta Americana L
… cardiacum increase the concentration of several fatty acids in cockroach fat body trophocytes. The phospholipase A{dollar}sb2{dollar} (PLA{dollar}sb2){dollar} activator melittin has a similar effect. The fatty acids include palmitic, stearic, oleic and linoleic acid. The hormone mediated release …

Comparative study of the ultrastructure and metabolism of the fat body of diapausing and nondiapausing larvae of the southwestern corn borer, Diatraea grandiosella Dyar (lepidoptera : pyralidae)
… general inactivity and lower metabolic rate. The fat body is the center of intermediary metabolism in insects, and it has been suggested that the fat body is in some respects analogous to the mammalian liver (Kilby, 1963). It is a tissue which has storage and synthetic capabilities and readily …

Endocrine control of fat body composition and effects of the insect growth regulators methoprene and pyriproxyfen on the development and reproduction of the Argentinian cockroach, Blaptica dubia Serville (Blattaria: Blaberidae)
… of adult life for the first gonadotropic cycle). Body weight changes of adult females are closely related with the reproductive processes of ovarian growth, ootheca formation, ootheca deposition, and hatching of the nymphs. The biochemical composition of the fat body was analyzed and revealed the …

The signal transduction of the adipokinetic hormone and regulation of energy metabolism in the cricket, Gryllus bimaculatus de Geer (Ensifera: Gryllidae)
The fat body from the cricket, Gryllus bimaculatus incorporates acetate, glycerol or palmitate into lipid in vitro. Adipokinetic hormone (AKH) inhibits acetate incorporation into lipid by the fat body from adult crickets in vitro. AKH inhibits palmitate incorporation into lipid to a small extent, …

Evaluation of Adipokinetic Hormone Receptor Function Suggests a Single Tissue is Responsible for Starvation Phenotypes in Drosophila.
… in times of metabolic stress. AKH signals to the fat body where it induces both hypertrehalosemia and hyperlipemia. AKH secretion also leads to starvation-induced hyperactivity, a foraging behavior. Genetic ablation of AKH cells or a genetic deletion of the AKH receptor (AKHR) results in flies …

Systemic and local signalling regulating neural stem cell proliferation
… in response to dietary amino acids sensed by the fat body, a sensor organ analogous to liver and adipose tissue in mammals. Previously unknown signals from the fat body are transmitted to the bloodbrain barrier (BBB) glia on the surface of the brain. The glia secrete insulin-like peptides, which …

Nutritional regulation of neural stem cell reactivation in Drosophila melanogaster
… fed a diet containing essential amino acids. The fat body, a functional homologue of the liver and adipose tissue, acts as a systemic nutrient sensor. Existing evidence from both in vivo and in vitro studies suggest that upon sensing dietary amino acids, the fat body secretes unknown factor(s) …

Genetically Modifying Mosquitoes Without Compromising Fitness: Can It Be Done?
… line with increased insulin signaling in the fat body. Surprisingly, these transgenic mosquitoes survived significantly longer than their non-transgenic siblings, while in nearly every other organism increased IIS resulted in a decrease in lifespan. In this work, we sought to define how the …

Effects of acetyl salicyclic acid on Drosophila models of cancer-inflammation
… cells infiltrate and adhere to cells of the fat body. The fat body is a large organ in fly larvae and akin to the mammalian liver. In wild type larvae, hematopoietic cells exhibit limited rounds of division, and circulating cells in the hemolymph do not stick to fat body. Our hypothesis was …

Estudo da atividade reprodutiva de hyla truncata Izecksohn, 1959 (Anura, Hylidae) na Restinga de Maricá, RJ
… monthly from September 1986 to August 1988. The body, ovaries, oviducts, and fat bodies weights were recorded for each animal. The ovaries and testes were fixed for histological assessment of maturity condition. Organs weights were expressed as percentage of body weight, and treated as IGS …

Hedgehog Signaling Plays a Conserved Role in Inhibiting Fat Formation
… the Hh pathway were expressed in the Drosophila fat body. Activating Hh signaling specifically in fat body inhibited fly fat formation. Conversely, blocking Hh signaling specifically in fat body stimulated fly fat formation. Analysis in mammalian models suggested the presence of functional Hh …

Acer, a homologue of the human angiotensin-1 converting enzyme, modulates the response of sleep, glycogen storage, lifespan, fecundity and stress resistance to diet in Drosophila melanogaster
… homolog ACER, which is expressed within the fly fat body which is similar in structure to human adipose cells, may highlight a role for ACE in adipose tissue. To investigate the role of ACE-like enzymes in dietary effects on ageing-related and circadian health, function and metabolism we are …
