A pair of ascending neurons in the subesophageal zone mediates aversive sensory inputs-evoked backward locomotion in Drosophila larvae

Posted on by

Animals generally avoid an unwanted situation by escaping stereotype behavior. For example, Drosophila larvae often escape from aversive stimuli in the head, such as mechanical stimuli and blue light irradiation, with rear drive. The response to the aversive stimulation is mediated by a variety of sensory neurons including mechanosensory class III da (C3da) sensory neurons and blue light responsive da class IV (C4da) sensory neurons and this Bolwig organ (BO). How different sensory pathways evoke the rear drive circuit level is still not fully understood.

Here we show that a pair of cholinergic neurons in subesophageal zone, designated AMBS, evoking a strong backward movement upon activation optogenetic. Anatomic and functional analysis showed that AMBS act upstream mDNS, command-like neurons to move backwards. Functional analysis further suggests that special AMBS deliver blue light information from neuron C4da hostility to mDNS to obtain a rear drive, while the hostility of convergent BO information on mDNS through AMB-independent pathway. We also found that, unlike in adult flies, mDNS is removed to a dead-end-evoked retreat into larvae. Our findings thus reveal the neural circuit in which two blue lines of light-sensing different gathered at a command such as neurons to generate driving force behind the strong, and suggest that different but most excessive neuronal circuits including commands such as neurons may be used to push back the driving in response to stimuli different sensory as well as in adults and larvae.


How insects navigate the complex smell of fur, where the location and timing uncertain smelly package, is still unclear. Here we imaged a complex odor fur along with free-running flies, measured how behavior is formed by a meeting with the smell of individual packages. We find that the navigation is stochastic and not rely on continuous modulation speed or orientation. Instead, it turns stochastic flies with saccades stereotypes, the direction of bias against the wind by the smell before the meeting time, while the amount and rate of saccades remain constant.

Dissection and Live-Imaging Final Drosophila embryo gonad

The gonads of male Drosophila melanogaster embryo is profitable models to study various aspects of developmental biology including, but not limited to, the development of germ cells, biology Pirna, and the establishment of niche. Here, we present a dissection techniques for live-image gonads ex vivo during the period when the live-imaging in vivo is not very effective. These protocols outline how to transfer embryos for imaging dish, choose the right-staged embryos male and gonads dissected from the surrounding tissue while maintaining structural integrity. Following dissection, the gonads can be imaged using confocal microscopy to visualize the dynamic cellular processes.

The surgical procedure requires a great time and dexterity, but we provide insight on how to avoid common mistakes and how to overcome these challenges. To our knowledge this is the first dissection protocol for Drosophila embryonic gonad, and will allow live-imaging during the window of time otherwise inaccessible. This technique can be combined with pharmacological or cell-type specific transgenic manipulation to study every dynamic process that occurs within or between cells in the gonads their natural environment.

Parasitoid wasp venom vesicles (venosomes) sign in Drosophila melanogaster lamellocytes through endocytic pathway flotillin / lipid raft-dependent

Venosomes is extracellular vesicles found in the venom of Leptopilina endoparasitoids wasps, which transport and targeted virulence factors to ruin encapsulation with lamellocytes egg parasitoids of Drosophila melanogaster larvae host them. Using co-immunolocalization of neon venosomes boulardi L. and one-transported suspected virulence factors, LbGAP, with a marker known as cellular endocytosis, we show that endocytosis by lamellocytes venosomes process is not dependent on clathrin or macropinocytosis and internalization seems to bypass the early endosomal compartment Rab5. After internalization, LbGAP strong colocalizes with flotillin-1 and GPI-anchored proteins Atilla / L1 (lamellocyte surface markers) shows entries that occur through flotillin / lipid raft-dependent pathway. Once internalized, venosomes reach all intracellular compartments, including late and recycling endosomes, lysosomes and endoplasmic reticulum network. Venosomes therefore enter their target cells with specific mechanisms and virulence factors are widespread in the compartment to lamellocytes’ for their Damaging functions.


Transdifferentiation is the conversion of the type of cells that are already differentiated into other types of cells without the involvement of stem cells. This transition is also described in the case of vertebrate immune cells, as well as in Drosophila melanogaster, which therefore serves as a suitable model to study the process in detail. In Drosophila larvae, single-cell sequencing method newest allows clustering of phagocyte blood cells, which plasmatocytes, capable of transdifferentiation into encapsulating cells, which lamellocytes. Here we summarize the available data from previous years on the transition plasmatocyte-lamellocyte, and made an effort to align them with the blood cell grouping based transcriptome to better understand the underlying mechanisms of transdifferentiation in Drosophila, and in general.

Teiresias, the target gene encoding a vain-transmembrane protein immunoglobulin superfamily, is required for neuronal feminization in Drosophila

This study aims to identify the target transcription of FruitlessBM (FruBM), which is the major isoform male-specific transcription factor that induces Frum sexual dimorphisms nerves. A promoter of axon-guidance robo1 factor gene carries a 16-bp palindrome motif Pal1, which Frum binding. Our genome-wide search for Pal1-homologous sequences produce ~ 200 candidate genes.

Among other things, the potential CG17716 encodes a transmembrane protein with extracellular immunoglobulin (Ig) -like domain similar to Robo1. Indeed, the excess is reduced FruBM CG17716 mRNA and protein expression. In fru-expressing neurons Mal cluster shows sexual dimorphism, we find that CG17716 knockdown in neurons women really changed all neurites all types of men.
