Acute and chronic pain can be extremely debilitating conditions, and a better understanding of their underlying pathology is necessary to provide effective treatment. C-Fibers are responsible for transmission of the majority of nociceptive signals, with TRPV1+ C-Fibers being specific to noxious heat. Formalin, an inflammatory agent, acts through TRPA1+ C-Fibers, which have a high degree of co-localization with TRPV1. Using a neonatal capsaicin preparation, which irreversibly ablates the majority of TRPV1+ C-Fibers, formalin- induced inflammation and subsequent ATF3 expression was investigated. Results provide evidence that in addition to a lack of thermal nociception, animals treated with neonatal capsaicin had a …
