Olfactory receptors, traditionally known for detecting odors, are also found in various non-olfactory tissues like the brain and skin. This discovery challenges our understanding of sensory and physiological processes and opens new possibilities for therapies and diagnostics. These receptors play diverse roles beyond smell, influencing metabolism, cell growth, and chemotaxis. Their ability to respond to various chemicals can be used in bioengineering for biosensors and targeted treatments. This review explores how olfactory receptors, expressed in unexpected places, may aid neural regeneration in the central nervous system. It also highlights compounds that can activate these receptors to start regenerative processes, suggesting their potential as therapeutic targets.
Ectopic olfactory receptors can be targeted for therapeutic interventions in various diseases, including dermatitis, psoriasis, prostate cancer, and neurodegenerative disorders.
The presence and activity of olfactory receptors in non-olfactory tissues can be used to develop novel diagnostic tools for early disease detection and monitoring.
The ability of olfactory receptors to respond to a wide array of chemical ligands can be harnessed for the development of novel biosensors and targeted therapies.
