Prior activity of olfactory receptor neurons is required for proper sensory processing and behavior in Drosophila larvae

Project description:Animal responses to their environment rely on activation of sensory neurons by external stimuli. In many sensory systems, however, neurons display basal activity prior to the external stimuli. This prior activity is thought to modulate neural functions, yet its impact on animal behavior remains elusive. Here, we reveal a potential role for prior activity in olfactory receptor neurons (ORNs) in shaping larval olfactory behavior. We show that prior activity in larval ORNs is mediated by the olfactory receptor complex (OR complex). Mutations of Orco, an odorant co-receptor required for OR complex function, cause reduced attractive behavior in response to optogenetic activation of ORNs. Calcium imaging reveals that Orco mutant ORNs fully respond to optogenetic stimulation but exhibit altered temporal patterns of neural responses. These findings together suggest a critical role for prior activity in information processing upon ORN activation in Drosophila larvae, which in turn contributes to olfactory behavior control.

RNAseq of mouse olfactory sensory neurons populations

Project description:Transcriptomic analysis of two cellular populations of the mouse olfactory mucosa. 6 x 10,000 olfactory sensory neurons (OSNs) were captured by FACS. Three samples from a high OMP-expressing population and three from a low OMP-expressing population. The RNA from each sample was sequenced on the Illumina Hiseq platform. This data is part of a pre-publication release.

Comparison of olfactory sensory neuron subtypes

Project description:Olfactory sensory neurons (OSNs) express a single abundant olfactory receptor (OR). To assess the differences in gene expression between different OSN sub-types we collected three pools of neurons that express one OR and compared them to three pools of neurons that express another. After extracting RNA from these pools, the samples were multiplexed and sequenced using the Illumina Hiseq2500 platform.This data is part of a pre-publication release.

Transcription profiling of mouse olfactory sensory neurons

Project description:The overall aim of the experiment is to understand the phenotype of mature mouse olfactory sensory neurons by analyzing the transcripts expressed and enriched in them as compared to the rest of the cell types in the olfactory epithelium (consisting of immature neurons, supporting cells, progenitor cells and cells in lamina propria) and brain ( with out the olfactory bulbs). Comparision with the other cell types in the olfactory epithelium should eliminate the transcripts commonly expressed in the olfactory epithelium and comparision with brain will eliminate the transcripts common to most neurons. Our gene chip data indicates that mature mouse olfactory sensory neurons express 10,000 genes. Mature OSNs specifically contained three clusters of over represented Gene ontology categories: smell, ion transport and cilia. Analysis for the functionally over represented categories among the transcripts with a positive signal in the mature OSNs yielded largely broad categories common to all cells with the exception of chromatin modelling and RNA processing categories. Biological process categories of movement, development and immune response came as under represented categories. Experiment Overall Design: To purify mature olfactory neurons we took advantage of the OMP-GFP mice. OMP(olfactory marker protein) is expressed specifically in mature olfactory and vomeronasal sensory neurons. In the OMP-GFP mice the coding region of OMP is replaced by GFP. We purified OSNs from the rest of the epithelium from these mice by using FACS. . We used the Affymetrix gene chips mouse expression set 430 (consisting of 430A and 430B chips). Our gene chip data is extensively validated by insitu hybridizations.
