Detection of Mitogenic and Genotoxic Effects of the Turkey Tail Medicinal Mushroom (Trametes versicolor, Agaricomycetes) Extracts from Mexico on Human Lymphocyte Cultures.

Abstract

Diseases caused by a compromised immune system, characterized by decreased production and diversification of T lymphocytes, such as immunodeficiencies or chronic infections, are becoming increasingly prominent. These diseases lead to increased vulnerability to infections caused by parasites, viruses, bacteria, fungi, and other microorganisms. According to various articles, Trametes versicolor has been used as immunotherapy and cancer treatment due to its polysaccharides, which have shown their value in traditional medicine. However, most of the studies have been done with Asian samples. For this reason, the aim of this study was to evaluate the effect of samples of Mexican T. versicolor on human lymphoid cells. Of various extracts, the one with the best T cell proliferative response was the extract produced by maceration in water at room temperature, but all treatments in aqueous and ethanolic extracts increased the lymphocyte count, showing that extracts of Mexican T. versicolor also have compounds that stimulate T cells. Unfortunately, genetic damage expressed as an increment in micronuclei count was identified, so using these fungus extracts in traditional medicine would require careful control of recommended doses.
