Regulation of synthesis of larval serum proteins after transplantation of larval fat body into adult Drosophila melanogaster.
The larval serum proteins, LSP1 and LSP2, of Drosophila melanogaster are synthesized by the fat body during the third instar. We examined the potential for LSP synthesis by fat body implants in adult flies. Fat body from third instar donors will continue to synthesize LSPs in both males and females. Implants from late second instar larvae will start synthesizing LSP1 and LSP2 in females but onl...
متن کاملSerpent regulates Drosophila immunity genes in the larval fat body through an essential GATA motif.
Insects possess a powerful immune system, which in response to infection leads to a vast production of different antimicrobial peptides. The regulatory regions of many immunity genes contain a GATA motif in proximity to a kappaB motif. Upon infection, Rel proteins enter the nucleus and activate transcription of the immunity genes. High levels of Rel protein-mediated Cecropin A1 expression previ...
متن کاملToll-dependent antimicrobial responses in Drosophila larval fat body require Spätzle secreted by haemocytes.
In Drosophila, the humoral response characterised by the synthesis of antimicrobial peptides (AMPs) in the fat body (the equivalent of the mammalian liver) and the cellular response mediated by haemocytes (blood cells) engaged in phagocytosis represent two major reactions that counter pathogens. Although considerable analysis has permitted the elucidation of mechanisms pertaining to the two res...
متن کاملThe role of larval fat cells in adult Drosophila melanogaster.
In the life history of holometabolous insects, distinct developmental stages are tightly linked to feeding and non-feeding periods. The larval stage is characterized by extensive feeding, which supports the rapid growth of the animal and allows accumulation of energy stores, primarily in the larval fat body. In Drosophila melanogaster access to these stores during pupal development is possible ...
متن کاملDrosophila larval NMJ immunohistochemistry.
The Drosophila neuromuscular junction (NMJ) is an established model system used for the study of synaptic development and plasticity. The widespread use of the Drosophila motor system is due to its high accessibility. It can be analyzed with single-cell resolution. There are 30 muscles per hemisegment whose arrangement within the peripheral body wall are known. A total of 31 motor neurons attac...
