The main goal of this project is to close data gaps and establish human cell culture-based tests for the toxicity of natural toxins from fungi. These are important steps in the development of new methods for chemical risk assessment.<\/p>\n\n\n<\/div>\n\n\n\n

Background<\/h2>\n\n\n\n

Mycotoxins are natural, low molecular secondary metabolites from different fungi that can pose adverse health effects in humans. Workers may be exposed to mycotoxins from the genus Alternaria<\/em> in occupations such as agriculture, waste management, and food and feed production. No OELs for Alternaria mycotoxins exist which at least partly is due to the lack of knowledge about their toxic properties. This project aims to close data gaps about Alternaria<\/em> mycotoxins to generate necessary knowledge for future risk assessment and setting of OELs.<\/p>\n\n\n\n

What we study in this project<\/h2>\n\n\n\n

STAMI will contribute to the characterization of immunotoxic effects of Alternaria<\/em> toxins in cell-culture models. The role of Toll-Like receptors in the immune system is to recognize molecular structures or patterns associated with infectious agents, damage or adverse effects. We study how the mycotoxins can modify activation of Toll-Like receptors 2 and 4 (TLR2 and TLR4). Cell lines that have been genetically modified to overexpress either TLR2 or TLR4 are used in these studies. <\/p>\n\n\n\n

In the second phase of the project, we study which immune response genes are induced or repressed after exposure of an advanced cell culture model of human bronchial epithelium (EpiAirway) to the mycotoxins. The goal of these studies is to evaluate if bronchial epithelium is a target organ for Alternaria<\/em> toxins. A secondary goal is to evaluate if EpiAirway maybe considered a suitable model for characterizing inhalation toxicity of chemicals.<\/p>\n\n\n\n
