Assaying Thermo-nociceptive Behavior in Drosophila Larvae.

ABSTRACT: Thermo-nociception, the detection and behavioral response to noxious temperatures, is a highly conserved action to avoid injury and ensure survival. Basic molecular mechanisms of thermal responses have been elucidated in several model organisms and are of clinical relevance as thermal hypersensitivity (thermos-allodynia) is common in neuropathic pain syndromes. Drosophila larvae show stereotyped escape behavior upon noxious heat stimulation, which can be easily quantified and coupled with molecular genetic approaches. It has been successfully used to elucidate key molecular components and circuits involved in thermo-nociceptive responses. We provide a detailed and updated protocol of this previously described method ( Tracey et al., 2003 ) to apply a defined local heat stimulus to larvae using a fast-regulating hot probe.

Nociceptive neurons protect Drosophila larvae from parasitoid wasps.

Project description:BackgroundNatural selection has resulted in a complex and fascinating repertoire of innate behaviors that are produced by insects. One puzzling example occurs in fruit fly larvae that have been subjected to a noxious mechanical or thermal sensory input. In response, the larvae "roll" with a motor pattern that is completely distinct from the style of locomotion that is used for foraging.ResultsWe have precisely mapped the sensory neurons that are used by the Drosophila larvae to detect nociceptive stimuli. By using complementary optogenetic activation and targeted silencing of sensory neurons, we have demonstrated that a single class of neuron (class IV multidendritic neuron) is sufficient and necessary for triggering the unusual rolling behavior. In addition, we find that larvae have an innately encoded preference in the directionality of rolling. Surprisingly, the initial direction of rolling locomotion is toward the side of the body that has been stimulated. We propose that directional rolling might provide a selective advantage in escape from parasitoid wasps that are ubiquitously present in the natural environment of Drosophila. Consistent with this hypothesis, we have documented that larvae can escape the attack of Leptopilina boulardi parasitoid wasps by rolling, occasionally flipping the attacker onto its back.ConclusionsThe class IV multidendritic neurons of Drosophila larvae are nociceptive. The nociception behavior of Drosophila melanagaster larvae includes an innately encoded directional preference. Nociception behavior is elicited by the ecologically relevant sensory stimulus of parasitoid wasp attack.

Cytokine signaling mediates UV-induced nociceptive sensitization in Drosophila larvae.

Project description:Heightened nociceptive (pain) sensitivity is an adaptive response to tissue damage and serves to protect the site of injury. Multiple mediators of nociceptive sensitization have been identified in vertebrates, but the complexity of the vertebrate nervous system and tissue-repair responses has hindered identification of the precise roles of these factors.Here we establish a new model of nociceptive sensitization in Drosophila larvae, in which UV-induced tissue damage alters an aversive withdrawal behavior. We find that UV-treated larvae develop both thermal hyperalgesia, manifested as an exaggerated response to noxious thermal stimuli, and thermal allodynia, a responsiveness to subthreshold thermal stimuli that are not normally perceived as noxious. Allodynia is dependent upon a tumor necrosis factor (TNF) homolog, Eiger, released from apoptotic epidermal cells, and the TNF receptor, Wengen, expressed on nociceptive sensory neurons.These results demonstrate that cytokine-mediated nociceptive sensitization is conserved across animal phyla and set the stage for a sophisticated genetic dissection of the cellular and molecular alterations responsible for development of nociceptive sensitization in sensory neurons.

Duox mediates ultraviolet injury-induced nociceptive sensitization in Drosophila larvae.

Project description:BackgroundNociceptive sensitization is an increase in pain perception in response to stimulus. Following brief irradiation of Drosophila larvae with UV, nociceptive sensitization occurs in class IV multiple dendritic (mdIV) neurons, which are polymodal sensory nociceptors. Diverse signaling pathways have been identified that mediate nociceptive sensitization in mdIV neurons, including TNF, Hedgehog, BMP, and Tachykinin, yet the underlying mechanisms are not completely understood.ResultsHere we report that duox heterozygous mutant larvae, which have normal basal nociception, exhibit an attenuated hypersensitivity response to heat and mechanical force following UV irradiation. Employing the ppk-Gal4 line, which is exclusively expressed in mdIV neurons, we further show that silencing duox in mdIV neurons attenuates UV-induced sensitization.ConclusionsOur findings reveal a novel role for duox in nociceptive sensitization of Drosophila larvae, and will enhance our understanding of the mechanisms underlying this process in Drosophila sensory neurons.

Ethanol-guided behavior in Drosophila larvae.

Project description:Chemosensory signals allow vertebrates and invertebrates not only to orient in its environment toward energy-rich food sources to maintain nutrition but also to avoid unpleasant or even poisonous substrates. Ethanol is a substance found in the natural environment of Drosophila melanogaster. Accordingly, D. melanogaster has evolved specific sensory systems, physiological adaptations, and associated behaviors at its larval and adult stage to perceive and process ethanol. To systematically analyze how D. melanogaster larvae respond to naturally occurring ethanol, we examined ethanol-induced behavior in great detail by reevaluating existing approaches and comparing them with new experiments. Using behavioral assays, we confirm that larvae are attracted to different concentrations of ethanol in their environment. This behavior is controlled by olfactory and other environmental cues. It is independent of previous exposure to ethanol in their food. Moreover, moderate, naturally occurring ethanol concentration of 4% results in increased larval fitness. On the contrary, higher concentrations of 10% and 20% ethanol, which rarely or never appear in nature, increase larval mortality. Finally, ethanol also serves as a positive teaching signal in learning and memory and updates valence associated with simultaneously processed odor information. Since information on how larvae perceive and process ethanol at the genetic and neuronal level is limited, the establishment of standardized assays described here is an important step towards their discovery.

Identification of genes enriched in nociceptive neurons of Drosophila larvae

Project description:This study aims to identify genes whose expression is enriched in the nociceptive neurons of Drosophila larvae. These neurons are involved in detecting noxious mechanical and noxious thermal stimuli. Four replicates each for Class I md-da neurons (2-21Gal4>>UAS-mCD8GFP) and Class IV md-da (ppk-GAL4>>UAS-mCD8GFP) neurons were analyzed. RNA from 50-60 neurons for each replicate was isolated by laser capture microdissection. RNA was amplified using the WT-Ovation Pico Kit from NuGen technologies. RNA was fragmented and labeled using the FL-Ovation cDNA Biotin Module V2 (NuGen Technologies). RNA was hybridized to arrays and data scanned at the Translational Genomics Research Institute.

A novel thermosensitive escape behavior in Drosophila larvae.

Project description:We describe a novel thermosensitive escape behavior in Drosophila larvae and a simple assay to accurately define the response temperature. When a larva is placed in a droplet of water that is subsequently heated, a stereotypical escape response is robustly elicited at 29°C. Larvae defective for the painless TRP receptor, or blocked in the function of class IV multi-dendritic sensory dendrites respond to this stimulus at reproducibly higher temperature (34°C). The escape response has novel behavioral components and a lower temperature threshold in comparison with the responses to touch with a hot needle. Furthermore the assay minimizes operator bias that is present in current tests of thermosensitive nociception and generates a precise determination of temperature at the point of response. This response is highly reproducible and directly applicable to genetic and neural circuit analysis of a simple escape behavior.

Nociceptive interneurons control modular motor pathways to promote escape behavior in Drosophila.

Project description:Rapid and efficient escape behaviors in response to noxious sensory stimuli are essential for protection and survival. Yet, how noxious stimuli are transformed to coordinated escape behaviors remains poorly understood. In Drosophila larvae, noxious stimuli trigger sequential body bending and corkscrew-like rolling behavior. We identified a population of interneurons in the nerve cord of Drosophila, termed Down-and-Back (DnB) neurons, that are activated by noxious heat, promote nociceptive behavior, and are required for robust escape responses to noxious stimuli. Electron microscopic circuit reconstruction shows that DnBs are targets of nociceptive and mechanosensory neurons, are directly presynaptic to pre-motor circuits, and link indirectly to Goro rolling command-like neurons. DnB activation promotes activity in Goro neurons, and coincident inactivation of Goro neurons prevents the rolling sequence but leaves intact body bending motor responses. Thus, activity from nociceptors to DnB interneurons coordinates modular elements of nociceptive escape behavior.

Optogenetic manipulation of neural circuits and behavior in Drosophila larvae.

Project description:Optogenetics is a powerful tool that enables the spatiotemporal control of neuronal activity and circuits in behaving animals. Here, we describe our protocol for optical activation of neurons in Drosophila larvae. As an example, we discuss the use of optogenetics to activate larval nociceptors and nociception behaviors in the third-larval instar. We have previously shown that, using spatially defined GAL4 drivers and potent UAS (upstream activation sequence)-channelrhodopsin-2?YFP transgenic strains developed in our laboratory, it is possible to manipulate neuronal populations in response to illumination by blue light and to test whether the activation of defined neural circuits is sufficient to shape behaviors of interest. Although we have only used the protocol described here in larval stages, the procedure can be adapted to study neurons in adult flies--with the caveat that blue light may not sufficiently penetrate the adult cuticle to stimulate neurons deep in the brain. This procedure takes 1 week to culture optogenetic flies and ~1 h per group for the behavioral assays.

A Plastic Visual Pathway Regulates Cooperative Behavior in Drosophila Larvae.

Project description:Cooperative behavior emerges in biological systems through coordinated actions among individuals [1, 2]. Although widely observed across animal species, the cellular and molecular mechanisms underlying the establishment and maintenance of cooperative behaviors remain largely unknown [3]. To characterize the circuit mechanisms serving the needs of independent individuals and social groups, we investigated cooperative digging behavior in Drosophila larvae [4-6]. Although chemical and mechanical sensations are important for larval aggregation at specific sites [7-9], an individual larva's ability to participate in a cooperative burrowing cluster relies on direct visual input as well as visual and social experience during development. In addition, vision modulates cluster dynamics by promoting coordinated movements between pairs of larvae [5]. To determine the specific pathways within the larval visual circuit underlying cooperative social clustering, we examined larval photoreceptors (PRs) and the downstream local interneurons (lOLPs) using anatomical and functional studies [10, 11]. Our results indicate that rhodopsin-6-expressing-PRs (Rh6-PRs) and lOLPs are required for both cooperative clustering and movement detection. Remarkably, visual deprivation and social isolation strongly impact the structural and functional connectivity between Rh6-PRs and lOLPs, while at the same time having no effect on the adjacent rhodopsin-5-expressing PRs (Rh5-PRs). Together, our findings demonstrate that a specific larval visual pathway involved in social interactions undergoes experience-dependent modifications during development, suggesting that plasticity in sensory circuits could act as the cellular substrate for social learning, a possible mechanism allowing an animal to integrate into a malleable social environment and engage in complex social behaviors.

Assaying uptake of endocrine disruptor compounds in zebrafish embryos and larvae.

Project description:To study the effects of environmental endocrine disruptor compounds (EDCs) on aquatic animals, embryos and larvae are typically incubated in water containing defined concentrations of EDCs. However, the amount of EDC uptake into the animal is often difficult to determine. Using radiolabeled estradiol ([3H]E2), we previously developed a rapid, straightforward assay to measure estradiol uptake from water into zebrafish embryos and larvae. Here, we extend this approach to measure the uptake of two additional EDCs, bisphenol A (BPA) and ethinyl estradiol (EE2). As with E2, the uptake of each compound by individual larvae was low (<6%), and increased with increasing concentration, duration, and developmental stage. We found that E2 and EE2 had similar uptake under equivalent exposure conditions, while BPA had comparatively lower uptake. One application of this assay is to test factors that influence EDC uptake or efflux. It has been suggested that persistent organic pollutants (POPs) inhibit ABC transporters that may normally efflux EDCs and their metabolites, inducing toxicity in aquatic organisms. We measured [3H]E2 levels in zebrafish in the presence or absence of the POP PDBE-100, and cyclosporine A, a known inhibitor of ABC transporters. Neither chemical significantly affected [3H]E2 levels in zebrafish, suggesting that zebrafish maintain estradiol efflux in the presence of PDBE-100, independently of cyclosporine A-responsive transporters. These uptake results will be a valuable reference for EDC exposure studies in developing zebrafish, and provide a rapid assay to screen for chemicals that influence estrogen-like EDC levels in vivo.
