Transcriptional profiling of sensory neurons
+61 3 834 46457
In the respiratory system, sensory neurons are critical for the ongoing physiological control of breathing as well as protecting against potentially damaging stimuli that could adversely affect ventilation. Their disordered activity contributes the coughing, dyspnoea and hyperreactivity characteristic of many lung diseases. Although respiratory sensory neurons are known to be functionally heterogeneous, very little is known about the molecular characteristics that define distinct populations.
In this project we are assessing the transcriptional profile of individual sensory neurons using RNA sequencing to better define cellular heterogeneity and to identify novel regulators of sensory neuron function. The project further aims to define changes in sensory neuron transcriptomes associated with viral pulmonary disease.
