Abstract: The described invention provides a method and kit for treating a lupus condition with N-acetyl-L-cysteine (NAC) compositions that improve lupus disease activity driven by a decrease in the activity of the mammalian target of rapamycin (mTOR). The compositions of the described invention is effective to: (1) reduce fatigue; (2) reduce cognitive/inattentive component of attention deficit and hyperactivity (ADHD) self-report scale (ASRS); (3) reduce inflammation, for example, as measured by the systemic lupus erythematosus disease activity index (SLEDAI), and the British Isles Lupus Assessment Group (BILAG) score; (4) modulate mitochondrial potential and (5) reduce T cell cycle dysfunction driven by a decrease in the activity of the mammalian target of rapamycin (mTOR) in patients suffering from systemic lupus erythematosus (SLE).

Abstract: Transaldolase is an enzyme which acts as an autoantigen in immune-related neurodegenerative diseases, particularly multiple sclerosis. Human transaldolase, the DNA coding therefore, peptides derived therefrom, and DNA control elements associated therewith and anti-transaldolase antibodies are disclosed. These compositions are useful in methods such as immunoassays for detecting subjects making anti-transaldolase antibodies and diagnosing the neurodegenerative disease.
