RESUMO
Immune-neuronal interactions contribute to neuropathic pain. Thus, immune-competent cells such as microglia may provide targets for pain relief, as may infiltrating lymphocytes. We evaluated the nature of the lymphocyte response in the spinal cord in association with the maintenance of neuropathic allodynia. We assessed T cell contribution to pain processing by targeting these cells with Glatiramer acetate (GA) which when administered systemically reversed neuropathic allodynia, inhibited microglia response and increased IL-10 and IL-4 expressing T cells in neuropathic dorsal horns. These studies advance understanding of lymphocyte contribution to chronic pain and reveal a new mechanism of T cell intervention.
