What are aquaporins and why should I test for them?

Aquaporins are "water channel" proteins that are found in cell wall membranes of many biological cells that help with the transport of water through the cell. Aquaporins are particularly concentrated in the central nervous system (CNS). Certain foods containing aquaporins can have molecular mimicry with biological aquaporins. In other words, food antibodies can cross-react with CNS tissue. Therefore, elevated antibodies to food aquaporins may be linked to neurological autoimmunity, inflammation, and associated symptoms.
