Smell-receptor sensors to find body-signaling molecules

Olfactory receptor-based sensors for biomedical applications

NIH-funded research Georgia Institute of Technology · NIH-11322581

Researchers are building sensors from human smell receptors to find the natural molecules that switch on those receptors in body tissues, which could help people with conditions linked to those receptors.

What this research studies

This project uses sensors made from human olfactory receptors to test many chemicals and record which ones activate receptors that are also found in non-nose tissues. The team will generate large, high-quality datasets of receptor-ligand pairs and train machine learning models to predict ligands for orphan receptors. Identified ligands will be used to study how those receptors affect tissue processes like sperm movement and muscle repair. The work is laboratory-based and may use cell systems or tissue samples to map receptor pathways rather than offering direct treatments to participants.

Who could benefit from this research

Good fit: People with conditions affecting tissues that overexpress these olfactory receptors (for example fertility or muscle-regeneration problems) or who can provide tissue samples may be relevant to this work.

Not a fit: People with health issues unrelated to tissues that express these receptors or those seeking immediate treatment are unlikely to benefit directly from this laboratory-focused project.

Why it matters

Potential benefit: If successful, this work could reveal new biological pathways and lead to diagnostics or first-in-class therapies for conditions tied to these receptors.

How similar studies have performed: Some prior studies have identified ligands for individual ectopic olfactory receptors, but combining receptor-based sensors with large-scale machine learning to deorphanize many receptors is a relatively new and growing approach.
