Chemically induced immunotoxicity in a medium-term multiorgan bioassay for carcinogenesis with Wistar rats
(Toxicology and Applied Pharmacology, 2004-01-15) [Artigo]
A variety of chemicals can adversely affect the immune system and influence tumor development. The modifying potential of chemical carcinogens on the lymphoid organs and cytokine production of rats submitted to a medium-term ...
4th Symposium of Immunology: Tumor Immunobiology
(Annual Review of Biomedical Sciences, 2011) [Artigo]
This Abstract book includes all Abstracts of presentations at the 4th Symposion of Immunology: Tumor Immunology, which occurred in the São Paulo State University - UNESP, Bioscience Institute, Botucatu, SP, Brazil, from ...
Role of natural killer cells in antitumor resistance
(Annual Review of Biomedical Sciences, 2005-12-01) [Artigo]
Natural killer cells constitute a population of lymphocytes able to non-specifically destroy virus-infected and some kinds of tumor cells. Since this lytic activity was shown by non-immunized animals the phenomenon is ...
Antitumor properties of Ganoderma lucidum polysaccharides and terpenoids
(Annual Review of Biomedical Sciences, 2011-12-01) [Artigo]
Ganoderma lucidum is an edible medicinal mushroom with immunomodulatory and antitumor properties, which are mainly attributed to polysaccharides and triterpenes that can be isolated from mycelia, fruiting bodies and spores. ...
Effect of a polysaccharidic fraction of Agaricus blazei on colorectal carcinogenesis in rats with ulcerative colitis
(Annual Review of Biomedical Sciences, 2005) [Artigo]
Immunomodulatory activities associated with beta-glucan derived from Saccharomyces cerevisiae
(Physiological Research, 2005-01-01) [Artigo]
In this study we investigated the effect of beta-glucan derived from Saccharomyces cerevisiae on fungicidal activity, cytokine production and natural killer activity. Spleen and peritoneal cells from female C57BL/6 mice, ...
Natural Products from Cyanobacteria with Antimicrobial and Antitumor Activity
(Current Pharmaceutical Biotechnology, 2013-10-01) [Artigo]
Cyanobacteria are an important source of structurally bioactive metabolites, with cytotoxic, antiviral, anticancer, antimitotic, antimicrobial, specific enzyme inhibition and immunosuppressive activities. This study focused ...
Chemomodulation of human dendritic cell function by antineoplastic agents in low noncytotoxic concentrations
(Journal of Translational Medicine, 2009-07-10) [Artigo]
The dose-delivery schedule of conventional chemotherapy, which determines its efficacy and toxicity, is based on the maximum tolerated dose. This strategy has lead to cure and disease control in a significant number of ...
Efficiency of colon cancer RNA-transfected DC vaccine is enhanced by previous treatment of tumor cells with low concentration of 5-fluorouracil
(Journal of Immunology, 2012-05-01) [Resumo]
Chemotherapeutic agents in low noncytotoxic concentrations increase immunogenicity of human colon cancer cells
(Cellular Oncology, 2011-04-01) [Artigo]
Background We have recently reported that chemotherapeutic agents in ultra low noncytotoxic concentrations may block the ability of tumor cells to suppress functional activation of dendritic cells (DCs).Methods HCT-116 ...
