Insights into the effects of lanthanides on mammalian systems and potential applications

Lanthanides, a group of elements with unique chemical properties, have garnered significant attention for their varied biological effects, ranging from cytotoxic to protective, depending on concentration, cell type, and exposure conditions. This review provides a detailed examination of the biological interactions of lanthanides with mammalian systems, including humans, by exploring their impact on different cell lines and organisms. Through a systematic assessment of current research, this work highlights the dual nature of lanthanides, identifying them as both potential therapeutic agents and environmental toxins. Furthermore, it underscores the importance of understanding their mechanisms to mitigate health risks, particularly for those exposed occupationally or via environmental sources. The review concludes with an overview of knowledge gaps and future research directions necessary for unlocking the therapeutic potential of lanthanides while ensuring safety and sustainability in their applications.
