Effects of the Ayurved Siriraj Wattana recipe on functional and phenotypic characterization of cytokine-induced killer cells and dendritic cells in vitro.

Background: Ayurved Siriraj Wattana recipe (AVS073), has been prescribed as tonic, to increase appetite, and for pain relief. It also exhibits antioxidant, anti-inflammatory, immunomodulating and anti-cancer activities. However, the immunomodulatory effects on antigen-presenting cells and effector T cells remained elusive.

Sunitinib indirectly enhanced anti-tumor cytotoxicity of cytokine-induced killer cells and CD3⁺CD56⁺ subset through the co-culturing dendritic cells.

Cytokine-induced killer (CIK) cells have reached clinical trials for leukemia and solid tumors. Their anti-tumor cytotoxicity had earlier been shown to be intensified after the co-culture with dendritic cells (DCs). We observed markedly enhanced anti-tumor cytotoxicity activity of CIK cells after the co-culture with sunitinib-pretreated DCs over that of untreated DCs.

Statins enhance the effects of corticosteroids on the balance between regulatory T cells and Th17 cells.

Background: Plasticity of CD4(+) lymphocyte Th17/regulatory T cell (Treg) subsets is involved in the pathogenesis of chronic airway inflammatory diseases, such as asthma. Reversal of Th17/Treg cell balance towards Treg cells may be beneficial for the suppression of chronic Th2 cell-mediated inflammatory diseases, such as asthma. However, the effect of the combination of corticosteroids and a statin on the ratio of Treg/Th17 cells is unknown.

Human cytokine-induced killer cells specifically infiltrated and retarded the growth of the inoculated human cholangiocarcinoma cells in SCID mice.

Cytokine-induced killer (CIK) cells were examined for safety and efficacy for cholangiocarcinoma treatment. Several conditions of human CIK cells were examined using ex vivo cytotoxic assay and SCID mice pre-inoculated with cholangiocarcinoma cells. We monitored the ex vivo cytotoxicity, tumor sizes and immunohistochemistry.

Der p 1 suppresses indoleamine 2, 3-dioxygenase in dendritic cells from house dust mite-sensitive patients with asthma.

Background: Indoleamine 2, 3-dioxygenase (IDO), a tryptophan-degrading enzyme in dendritic cells (DCs), mediates an immunosuppressive effect on activated T lymphocytes. However, little is known about the effect of Der p 1 on IDO in human DCs.

Objective: The aim was to investigate the effect of Der p 1 on the expression and activity of IDO in monocyte-derived DCs from house dust mite (HDM)-sensitive patients with asthma.
