Inflammatory mediators, such as cytokines, chemokines and arachidonic acid compounds, lead to vascular permeability and dilation and increase sensitization and pain receptors. Proinflammatory cytokines, including tumor necrosis factor, are involved in the etiology of clinical neurological disorders. These cytokines activate nuclear factor-ÎºB (NF-ÎºB) which leads to the activation of different inflammatory genes. TNF implicated in neurological disorders has an important role in the activation of microglia and astrocytes. The inhibition of TNF may lead to the decrease of microglia activation and can be useful for therapeutic intervention. TNF, at the site of nerve injury may activate mast cells (MCs) which mediate pathologic events such as headache and pain. TNF is the only cytokine stored in mast cells and can be rapidly released along with biogenic amines after MC stimulation. Activation of MCs leads to NF-ÎºB and AP1 generation with release of many cytokines including TNF, IL-33 and IL-1. In this paper we discuss the role of TNF in MC activation, mediating pain and neurological disorders.
