Study reveals function of thousands of autoantibodies in blood

"Using human protein microarrays, the researchers examined the immune-response profiling of 166 individuals, including subject groups of Alzheimer's, Parkinson's, multiple sclerosis and breast cancer patients. Among the study's startling findings:
Most people have more than 1,000 discrete autoantibodies present in their blood and an individual's unique autoantibody profile remains relatively consistent over time.
Women have significantly more autoantibodies than men which may account for the higher incidence of autoimmune diseases among women.
Increasing age is accompanied by a corresponding increase in the number of detectable autoantibodies.
Alzheimer's, Parkinson's, multiple sclerosis and breast cancer patients all had measurably lower numbers of autoantibodies than age- and gender-matched controls."
