Korean Red Ginseng modulates immune function by upregulating CD4 + CD8 + T cells and NK cell activities on porcine.

In the present study, we investigated whether treatment with KRG improve the parameters of immune activity such as the cytotoxicity, populations of CD4+ CD8+ T cell, CD3- CD172- CD8+ NK cell and CD172+ monocyte as well as natural cytotoxicity receptors such as Nkp46, Nkp44, Nkp30. In results, KRG significantly increased these immune activities. These results indicate that KRG has distinct immune-enhancing effects by increasing the roles of T cells and NK cell in porcine.
