Transcriptomics of the Carotid Body.

Area of Science:

• Physiology
• Molecular Biology
• Cardiovascular Science

Background:

• The carotid body (CB) is a critical sensory organ involved in cardiovascular, respiratory, and metabolic regulation.
• Beyond its known role as an oxygen (O2) sensor, the CB functions as a multimodal sensor responding to various circulating stimuli.
• The precise mechanisms underlying this multimodal sensing capability remain incompletely understood, with even O2 sensing involving complex, convergent pathways.

Conclusions:

• High-throughput transcriptomics offers a powerful strategy for dissecting complex sensory mechanisms in the carotid body.
• The reviewed work highlights significant advancements in understanding CB multimodal sensing.
• Numerous areas requiring further experimental investigation have been identified, paving the way for future therapeutic strategies.
