Abstract
Energy storage and mobilization are fundamental to physiology and survival, yet their dysregulation drives obesity, diabetes, cancer, and age-related diseases. Drosophila melanogaster offers a tractable model for dissecting these pathways because its metabolic and endocrine circuits mirror those of vertebrates. In flies, the fat body functions like mammalian adipose and liver tissues, as it stores triacylglycerol and glycogen, produces lipoproteins, and serves as a major immune site. In addition, hepatocyte-like oenocytes direct lipid mobilization and trafficking during nutrient stress, synthesize cuticular hydrocarbons, and help regulate fertility and behavior. This review surveys discoveries enabled by single-cell genomics, metabolomics, and advanced genetics, with a focus on how the fat body and oenocytes integrate metabolism with reproduction, immunity, and aging.
期刊介绍:
Current Opinion in Insect Science is a new systematic review journal that aims to provide specialists with a unique and educational platform to keep up–to–date with the expanding volume of information published in the field of Insect Science. As this is such a broad discipline, we have determined themed sections each of which is reviewed once a year.
The following 11 areas are covered by Current Opinion in Insect Science.
-Ecology
-Insect genomics
-Global Change Biology
-Molecular Physiology (Including Immunity)
-Pests and Resistance
-Parasites, Parasitoids and Biological Control
-Behavioural Ecology
-Development and Regulation
-Social Insects
-Neuroscience
-Vectors and Medical and Veterinary Entomology
There is also a section that changes every year to reflect hot topics in the field.
Section Editors, who are major authorities in their area, are appointed by the Editors of the journal. They divide their section into a number of topics, ensuring that the field is comprehensively covered and that all issues of current importance are emphasized. Section Editors commission articles from leading scientists on each topic that they have selected and the commissioned authors write short review articles in which they present recent developments in their subject, emphasizing the aspects that, in their opinion, are most important. In addition, they provide short annotations to the papers that they consider to be most interesting from all those published in their topic over the previous year.
