Environmental Factors and the Impact of Heavy Metals on the Immune System
The industrial revolution and subsequent technological advancements over the past two centuries have led to significant socioeconomic improvements, including increased life expectancy. However, this progress has also resulted in substantial environmental burdens, where exposure to toxic substances constitutes a major health risk.
Heavy Metals and Immunological Dysregulation
Metals such as mercury (Hg), silver (Ag), and gold (Au) are known to accumulate in biological systems and interact with cellular components.
My research has demonstrated that these metals can induce immunological alterations by affecting antigen presentation, T-cell signaling, and cytokine networks. Such disruptions may lead to hypersensitivity reactions and autoimmunity, where the immune system erroneously targets self-structures. Autoimmune diseases represent the third most common disease group in Western societies and exhibit a marked gender disparity, with higher prevalence among women, suggesting hormonal and genetic interactions.
Genetic Determinants and Metal Homeostasis
Together with my colleagues, I have identified that polymorphisms in genes regulating metal transport and detoxification—such as metallothioneins and the HLA complex—play a critical role in both metal accumulation and immune response. These genetic factors influence the risk profile for autoimmune disease in the context of metal-induced immunotoxicity.
This knowledge is essential for developing predictive biomarkers and conducting risk assessments related to heavy metal exposure, as well as for understanding the complex interplay between environmental factors and genetic predisposition.
