Abstract

The Rheumatoid Arthritis (RA) is a polyarthritis autoimmune that results in a chronic systemic inflammation affecting synovial joints such as the Temporomandibular Joint (TMJ) and being the pain the main complaint of patients. A previous study (FAPESP # 2011/18951-6) demonstrated that the RA induced experimentally in rat's TMJ causes a persistent hypernociception linked to the formation and maintenance of inflammatory pannus, result of an increase in the migration of inflammatory cells, edema, release of cytokines such as TNF - alpha and IL - 1beta and Intercellular Adhesion Molecule (ICAM 1). Considering that sensory disorders induced followed by neural and/or peripheral tissue injuries are associated with activation of microglia, the purpose of this study is to evaluate the expression and activity of the microglial cells on the trigeminal subnucleus caudal in the induction and development of persistent inflammatory hypernociception induced by RA in rat's TMJ.
