Single-cell transcriptomic profiling of dorsal root ganglion: an overview

Area of Science:

• Neuroscience
• Genomics

Background:

• Dorsal root ganglion (DRG) neurons transmit sensory information from the periphery to the central nervous system.
• DRG neurons are diverse, responding to various stimuli like mechanical, thermal, and cold.
• Traditional classification relied on anatomical criteria, limiting functional understanding.

Purpose of the Study:

• To review and integrate current literature on single-cell transcriptomic profiling of DRG neurons.
• To provide a comprehensive understanding of DRG neuron molecular diversity and functional heterogeneity.
• To compare DRG neuron transcriptomes across human and rodent species.

Main Methods:

• Review of existing scientific literature.
• Analysis of single-cell RNA sequencing (scRNA-seq) and single-nucleus RNA-sequencing (snRNA-seq) data.
• Focus on transcriptomic profiling for cell type identification and functional annotation.

Main Results:

• Single-cell technologies have revolutionized the study of DRG neuron heterogeneity.
• Identification of distinct DRG neuron subpopulations based on molecular signatures.
• Detailed molecular and functional annotations of various DRG neuron types.

Conclusions:

• Single-cell transcriptomics offers unprecedented resolution into DRG neuron composition and function.
• This approach advances our understanding of sensory processing and neurological disorders.
• The review provides a valuable resource for researchers studying DRG neurons.
