What cultivates the diversity of spinocerebellar tract neurons? (biologists.com)

Spinocerebellar tract neurons relay proprioceptive sensory information about muscle tension and position from the body to the cerebellum. (biologists.com)
Previous retrograde tracing studies have shown that different subpopulations of spinocerebellar tract neurons exist along the rostrocaudal axis, which receive inputs from specific muscle groups that are often functionally antagonistic. (biologists.com)
This observation leads to the hypothesis that spinocerebellar tract neurons might integrate the information from each muscle pair and transmit the information to the cerebellum for further processing. (biologists.com)
While the anatomy and connectivity of spinocerebellar tract neurons have been described, the underlying molecular basis of their diversity and connectivity remains largely unknown. (biologists.com)
Understanding how spinocerebellar tract neurons are specified and form synapses with different subsets of peripheral sensory neurons could tell us more about how neurons find the right target in a distant and crowded neural nucleus or column and form synapses with the right partner.

first systematically characterized the anatomy of spinocerebellar tract neurons projecting to the cerebellum by retrograde labeling, identifying eight spatially distinct subpopulations, and then profiled the transcriptomic difference between cervical and thoracic spinocerebellar tract neurons. (biologists.com)
Transcriptomic analysis revealed differences in the expression of ion channels, neurotransmitter transporters, and transcription factors, suggesting that the spinocerebellar tract neurons in different segments obtain distinct transcriptional programs. (biologists.com)
To better characterize the heterogeneity of spinocerebellar tract neurons within each segment, the authors performed single cell RNA-seq and identified eight transcriptomically distinct clusters, among which one novel subtype, marked by Shox2, Scip, and Fam19A4, was examined in vivo and detected as a subpopulation in the caudal cervical segment. (biologists.com)
The authors then asked how these molecularly distinct subtypes of spinocerebellar tract neurons are specified. (biologists.com)
Indeed, different spinocerebellar tract neurons express a distinct combination of Hox genes. (biologists.com)
With the loss of function of Hoxc9, a critical regulator of thoracic segment for motor and interneurons, Clarke's column, a subpopulation of spinocerebellar tract neurons, failed to form in the thoracic segment. (biologists.com)
On the other hand, the other remaining spinocerebellar tract neurons in the thoracic segment stopped expressing their marker genes and started to express a combination similar to caudal cervical spinocerebellar tract neurons (Figure 1). (biologists.com)
Regarding circuit formation, thoracic spinocerebellar tract neurons received peripheral sensory innervations that are otherwise exclusive for cervical neurons in the lack of Hoxc9. (biologists.com)
The changes in gene expression and connectivity upon Hoxc9 loss of function are consistent with a conversion of cell identity from thoracic to cervical spinocerebellar tract neurons. (biologists.com)
