Dicer maintains the identity and function of proprioceptive sensory neurons

Project description:During development neurons achieve a high degree of specialization (Fishell and Heintz, 2013). Over time, while continuously recycling their components and despite transcriptional noise, their own respective properties remain intact. The transcription factors that play a large role in initially establishing neuronal identity can be required for maintaining it (Deneris and Hobert, 2014). Post-transcriptional regulation is also important to differentiation (Bian and Sun, 2011) but its role in maintaining cell identity is less established. To better understand how post-transcriptional regulation might contribute to cell identity, we examined the proprioceptive neurons in the dorsal root ganglion (DRG), a highly specialized sensory class, whose properties are well established and display clear differences when compared to other neurons in the ganglion. By conditionally ablating Dicer in mice, using a parvalbumin (Pvalb) driven cre, we impaired post-transcriptional regulation in the proprioceptive sensory neuron population. KO animals display a progressive form of ataxia at the beginning of the fourth postnatal week that is mirrored by a cell-death within the DRG. Before cell-loss, expression profiling shows a reduction of proprioceptor specific genes and an increased expression of non-proprioceptive genes normally enriched in other ganglion neurons. Furthermore, although central connections of these neurons are intact, the peripheral connections to the muscle are functionally impaired. Post-transcriptional regulation is therefore necessary to retain the transcriptional identity and support functional specialization of the proprioceptive sensory neurons.

Neuronal cell lines as model dorsal root ganglion neurons: a transcriptomic comparison

Project description:Aim: Dorsal root ganglion neuron-derived immortal cell lines including ND7/23 and F-11 cells have been used extensively as in vitro model systems of native peripheral sensory neurons. However, while it is clear that some sensory neuron-specific receptors and ion channels are present in these cell lines, a systematic comparison of the molecular targets expressed by these cell lines with intact peripheral neurons is lacking. Methods: we examined the expression of RNA transcripts in the human neuroblastoma-derived cell line, SH-SY5Y, and two dorsal root ganglion hybridoma cell lines, F-11 and ND7/23, using Illumina next-generation sequencing. Results: The expression profile of these three cell lines did not resemble any specific dorsal root ganglion neuron subclass. The cell lines lacked many markers for nociceptive sensory neurons, such as the transient receptor potential V1 gene, but expressed markers for both myelinated and unmyelinated neurons. Conclusion: This paper provides insights into the receptor repertoire expressed in common dorsal root ganglion neuron-derived cell lines, and illustrates the limits and potentials of these cell lines as tools for neuropharmacological exploration.

Whole-genome gene expression profiling of dorsal root ganglion neurons after nerve damage

Project description:We generated whole-genome gene expression profiles of dorsal root ganglion (DRG) neurons following nerve damage. DRG neurons extend one peripheral axon into the spinal nerve and one central axon into the dorsal root. The peripheral axon regenerates vigorously, while in contrast the central axon has little regenerative capacity. For this study, two groups of animals were subjected either to sciatic nerve (SN) or dorsal root (DR) crush, and at 12, 24, 72 hours and 7 days after the crush, lumbar DRGs L4, L5 and L6 were dissected and total RNA was extracted. For each time point after lesion, three biological replicate RNA samples were hybridized together with the common reference sample consisting of labeld RNA pooled from three unlesioned animals.

Distinct subtypes of proprioceptive dorsal root ganglion neurons regulate adaptive proprioception in mice.

Project description:Proprioceptive neurons (PNs) are essential for the proper execution of all our movements by providing muscle sensory feedback to the central motor network. Here, using deep single cell RNAseq of adult PNs coupled with virus and genetic tracings, we molecularly identify three main types of PNs (Ia, Ib and II) and find that they segregate into eight distinct subgroups. Our data unveil a highly sophisticated organization of PNs into discrete sensory input channels with distinct spatial distribution, innervation patterns and molecular profiles. Altogether, these features contribute to finely regulate proprioception during complex motor behavior. Moreover, while Ib- and II-PN subtypes are specified around birth, Ia-PN subtypes diversify later in life along with increased motor activity. We also show Ia-PNs plasticity following exercise training, suggesting Ia-PNs are important players in adaptive proprioceptive function in adult mice.
