Summary

<p>Abstract</p> <p>Background</p> <p>Congaplex^®and Immuplex^®are dietary supplements that have been traditionally used to support immune system function. The purpose of these experiments was to determine whether Congaplex^®and Immuplex^®affect immune function using primary and immortalized T lymphocytes.</p> <p>Methods</p> <p>Immortalized CEM and Jurkat T lymphocytes and primary peripheral mononuclear blood cells (PBMCs) were treated with the aqueous extracts from Congaplex^®and Immuplex^®to determine the effects of these products on cytokine production in activated T lymphocytes.</p> <p>Results</p> <p>Congaplex^®enhanced phytohemagglutinin/phorbol 12-myristate 13-acetate (PHA/PMA) stimulation of both CEM and Jurkat cells as measured by the production of cytokines, while Immuplex^®suppressed PHA/PMA-induced production of cytokines, with the exception of interleukin (IL)-8 which was enhanced by Immuplex^®. <it>In vitro </it>treatment of PBMCs from 10 healthy donors with Congaplex^®or Immuplex^®decreased PHA-stimulated production of interferon (IFN)-γ but increased the production of IL-13.</p> <p>Conclusions</p> <p>While the effects of Congaplex^®and Immuplex^®differed in these two models, these data demonstrate that the aqueous extracts from these two dietary supplements can affect the inflammatory response of T lymphocytes.</p>
