چکیده
Natural products may increase cytotoxic activity of Natural Killer Cells (NK) Tumor Necrosis Factor alpha (TNF-alpha) while decreasing DNA damage in patients with late-stage cancer. Pilot studies have suggested that a combination of Nutraceuticals can raise NK cell function and TNF-alpha alpha activity and result in improved clinical outcomes in patients with late stage cancer. The objective of the study is to determine if Nutraceuticals can significantly raise NK function and TNF levels in patients with late stage cancer. After informed consent was obtained, 20 patients with stage IV, end-stage cancer were evaluated (one bladder, five breast, two prostate, one neuroblastoma, two non-small cell lung, three colon, 1 mesothelioma, two lymphoma, one ovarian, one gastric, one osteosarcoma). Transfer Factor Plus (TFP+, 3 tablets 3 times per day), IMUPlus (non denatured milk whey protein, 40 gm/day); Intravenous (50 to 100 gm/day) and oral (1-2 gm/day) ascorbic acid; Agaricus Blazeii Murill teas (10 gm/day); Immune Modulator Mix (a combination of vitamin, minerals, antioxidants and immune-enhancing natural products); nitrogenated soy extract (high levels of genistein and dadzein) and Andrographis Paniculata (500 mg twice, daily) were used. Baseline NK function by standard 4 h 51Cr release assay and TNF alpha and receptor levels were measured by ELISA from resting and phytohemagglutinin (PHA) stimulated adherent and non-adherent Peripheral Blood Mononuclear Cell (PBMC). Total mercaptans and glutathione in plasma were taken and compared to levels measured 6 months later. Complete blood counts and chemistry panels were routinely monitored. As of a mean of 6 months, 16/20 patients were still alive. The 16 survivors had significantly higher NK function than baseline (p < .01 for each) and TNF-alpha levels in all four cell populations studied (p < .01 for each). Total mercaptans (p < .01) and TNF-alpha receptor levels were significantly reduced (p < .01). It was also observed that hemoglobin, hematocrit and glutathione levels were significantly elevated. The only toxicity noted was occasional diarrhea and nausea. The quality of life improved for all survivors by SF-36 form evaluation. An aggressive combination of immunoactive Nutraceuticals was effective in significantly increasing NK function, other immune parameters and hemoglobin from PBMC or plasma in patients with late stage cancers. Nutraceutical combinations may be effective in late stage cancers. Clinical outcomes evaluations are ongoing.

Killer Cell Immunoglobulin-Like Receptors Influence the Innate and Adaptive Immune Responses
Natural killer (NK) cells are a subset of lymphocytes which play a crucial role in early innate immune response against infection and tumor transformation. Furthermore, they secrete interferon-γ (IFN-γ) and tumor necrosis factor (TNF) prompting adaptive immu-nity. NK cells distinguish the unhealthy cells from the healthy ones through an array of cell-surface receptors. Human NK cells use inhibi...
متن کاملActivation of natural killer cells inhibits liver regeneration in toxin-induced liver injury model in mice via a tumor necrosis factor-alpha-dependent mechanism.
Liver lymphocytes are enriched in natural killer (NK) cells, and activation of NK cells by injection of polyinosinic-polycytidylic acid (poly I:C) inhibits liver regeneration in the partial hepatectomy model via production of IFN-gamma. However, the role of NK cells in liver regeneration in a model of carbon tetrachloride (CCl(4))-induced liver injury remains unknown. In this study, we investig...
متن کاملCytokine-induced apoptosis of human natural killer cells identifies a novel mechanism to regulate the innate immune response.
Interferon-gamma (IFN-gamma) is critical for an effective innate immune response against infection. A combination of interleukins (ILs) derived from activated T cells (IL-2) and monocytes (IL-12), or monocytes alone (IL-15 and IL-12), induces optimal production of IFN-gamma from natural killer (NK) cells. The mechanism by which human NK cells downregulate their production of IFN-gamma is unknow...
متن کاملDecreased hematopoiesis in bone marrow of mice with congestive heart failure.
Patients with heart failure are predisposed to infections and anemia, possibly due to reduced hematopoiesis. The proinflammatory cytokine tumor necrosis factor-alpha (TNF-alpha) is increased in heart failure, and it inhibits normal hematopoiesis, partly due to apoptosis through the effector molecule Fas. We examined bone marrow progenitor cells of mice with heart failure induced by acute myocar...

OBJECTIVES Ischemia/reperfusion injury is characterized by endothelial cell activation leading to increased expression of adhesion molecules such as inter-cellular adhesion molecule (ICAM)-1, vascular cell adhesion molecule (VCAM)-1, endothelial- and platelet-selectin (E- and P-selectin), and to the subsequent recruitment of leukocytes. The aim of the present study was to investigate the respec...
