Multiple sclerosis1 (MS) is an immune-mediated autoimmune demyelinating disease in humans. The initiating event in MS is unknown, but epidemiological evidence suggests that virus infections may be important and one possible mechanism for induction of infection-induced autoimmune disease is molecular mimicry. To test the ability of a virus encoding a self(More)
Molecular mimicry is the main postulated mechanism by which infectious agents induce autoimmune disease. A number of animal models have been utilized to establish a link between molecular mimicry and autoimmunity. However, a model of infectious disease whereby a natural pathogen expressing a known mimic epitope can induce autoimmunity to a known(More)
Molecular mimicry is the process by which T cells activated in response to determinants on an infecting microorganism cross-react with self epitopes, leading to an autoimmune disease. Normally, infection of SJL/J mice with the BeAn strain of Theiler's murine encephalomyelitis virus (TMEV) results in a persistent CNS infection, leading to a chronic(More)
The role of microglia and their contribution to the development and maintenance of pain states has emerged as an attractive field of study. Sensitization of central nociceptors and interneurons is thought to be responsible for the symptoms of chronic neuropathic pain states. Microglia interact with these neurons at the site of injury or disease as well as(More)
Microglia are the resident immune cells of the central nervous system (CNS) and share many immunological characteristics with peripheral macrophage. Microglia exist in a quiescent state in the healthy CNS, however, upon injury or infection, microglia become activated immune cells. Microglia have been implicated in playing an important role in several(More)
Theiler’s murine encephalomyelitis virus (TMEV) infection of susceptible mice leads to the development of demyelinating disease in the central nervous system (CNS) associated with an inflammatory immune response. The demyelinating disease in mice has similarities to multiple sclerosis in humans and is used as an experimental model for the human disease. The(More)
Theiler's murine encephalomyelitis virus (TMEV) infection of the central nervous system (CNS) induces a chronic, progressive demyelinating disease in susceptible mouse strains characterized by inflammatory mononuclear infiltrates and spastic hind limb paralysis. Our lab has previously demonstrated a critical role for TMEV- and myelin-specific CD4(+) T cells(More)
Neuropathic pain (NP) is a significant and disabling clinical problem with very few therapeutic treatment options available. A major priority is to identify the molecular mechanisms responsible for NP. Although many seemingly relevant pathways have been identified, more research is needed before effective clinical interventions can be produced. Initial(More)
Microglia are macrophage-like cells that populate the central nervous system (CNS) and become activated upon injury or infection. Microglia have been implicated as playing critical roles in various CNS diseases including multiple sclerosis (MS), a human autoimmune demyelinating disease, as well as in other neurodegenerative diseases. Two well-characterized(More)
