Agarwood is a resinous wood from the tree in the family Thymelaeaceae. It has been used as traditional medicine in China and Southeast Asia countries. This study was conducted to evaluate the potential of agarwood pill (AP) as a supplement to enhance immune function. In this study, immunity-enhancing activity was demonstrated in BALB/c male mice administered with AP for 10 days after intraperitoneal injection of cyclophosphamide (CPA). Results demonstrated that AP supplementation ameliorated spleen index and body weight changes of CPA-injected mice by increasing the proliferation of T- and B-lymphocytes as well as the activity of natural killer cells. Analysis of spleen-derived lymphocytes showed that counts of CD4+ and CD8+ T-cells were slightly recovered in the spleen of mice treated with a high dosage of AP. Serum levels of immune-related cytokines of tumor necrosis factor-α were notably restored after AP administration. In addition, serum levels of immunoglobulin (Ig) M and IgG were recovered by AP administration at a medium dosage. Furthermore, in analysis of ex vivo bone marrow-derived macrophages and dendritic cells, counts of immune-related interleukin-12, major histocompatibility complex (MHC)-I, MHC-II, CD80, and CD86 were significantly increased by AP treatment in concentration-dependent manner. This study provides reference data for the development of AP as a supplementation to enhance human immune function.
