Dr. Ari Vojdani, Chief Scientific Officer at Cyrex Labs, describes the two primary components of the immune system--humoral and cell-mediated immunity and how the Cyrex diagnostics are designed to measure both. The Cyrex food immune reactivity testing measures antibodies against raw, cooked, modified, and processed food proteins as the structure of these proteins can change and affect immune responses. Cyrex is also developing tests to measure antibodies against various gut bacteria, fungi, and toxins, and how these relate to autoimmune conditions.
Ari explains, "Cyrex performs lots of tests, but we can divide them based on the immune system. As you know, the immune system has two major components, the humoral and cell-mediated immunity. The humoral components of the immune system deal with measurements of antibodies. So when we get exposed to certain antigens, proteins of pathogens, food, or toxic chemicals, when they bind to human tissue, our body reacts to them, and the end result of that is specific antibody production against that specific protein or antigen."
"The second component of the immune system is cell-mediated immunity, which looks at different lymphocytes, their markers, such as whether it is a T-cell, B-cell, CD4, CD8, T helper 1, T helper 2, regulatory T cells, or natural killer cells. So that also could be abnormal in certain inflammatory and autoimmune disorders. That's why at Cyrex, the tests that they are performing are classified based on humoral and cell-mediated immunity."
"In 1986 and 1987, I developed the ELISA method for measuring antibodies against different food antigens. Then I did not have the knowledge about the importance of raw versus cooked or raw versus modified foods. I established the methodologies, and many others came to visit my laboratories. Years later, they started their own laboratories. So they continue using the same raw food for measuring antibodies in their own laboratories."
