C-Fos: A Neural Activity Marker For Craniofacial Pain Research, Weera Supronsinchai, Robin James Storer
Chulalongkorn University Dental Journal
It is well known that pain in animal models is difficult to measure. c-Fos, the protein product of the cellular immediate-early proto-oncogene gene, c-fos, can be activated in neuronal cells by noxious sensory stimuli including chemical irritation, mechanical, thermal, and electrical stimulation. The expression of c-Fos provides researchers with a tool by which the processing of somatosensory information, particularly nociception, from the craniofacial regions can be better understood. c-Fos is widely used as an indirect marker of neuronal activation after noxious stimulation in dental pain research, including in the trigeminal nervous system as activated by craniofacial or orofacial stimulation.
