Collapsible content


ColdDx has been evaluated in a human gene expression study to examine its effect on the immune system. Human blood samples treated with ColdDx in the presence and absence of an immune aggravator were assessed for the expression of 24 genes involved in inflammatory immune response. ColdDx significantly decreased the effects of the immune aggravation, indicating that ColdDx modulates the inflammatory immune response to reduce immune over-reactions.
