words only definitions & notes
  1. enterovirus
    any of a group of picornaviruses that infect the gastrointestinal tract and can spread to other areas (especially the nervous system)
    Other possible but unproven
    viral causes include enteroviruses, human herpesvirus 6, and human T-cell lymphotropic
    virus.
  2. autoantibody

    Some patients have
    abnormal IgG, with circulating autoantibodies and immune complexes.
  3. IgG
    one of the five major classes of immunoglobulins
    Various immunologic abnormalities have been reported;
    they include low levels of IgG, decreased lymphocytic proliferation, low interferon-γ levels in
    response to mitogens, and poor cytotoxicity of natural killer cells.
  4. mitogen
    an agent that triggers mitosis
    Various immunologic abnormalities have been reported;
    they include low levels of IgG, decreased lymphocytic proliferation, low interferon-γ levels in
    response to mitogens, and poor cytotoxicity of natural killer cells.

    circulation, and elevated levels of ACE.Data indicate that relatives of patients with CFS have
    an increased risk of developing the syndrome, suggesting a familial or genetic component.
