||Known for its high toxicity, beryllium can cause berylliosis, a serious pneumopathy, or chronic beryllium disease. The lymphocyte proliferation test (BeLPT) commonly used for detecting a worker's sensitivity to this metal offers little predictive value for the risks of contracting berylliosis. Knowing that this disease can take up to 30 years to develop in a sensitized worker, it is essential that a new effective detection tool be developed. By exploring experimental approaches, this research was able to determine the feasibility of methods for the selective characterization of target cells and the use of protein signatures on blood samples. A technique was also developed for quantifying beryllium in plasma, and the potential of complexing agents for displacing it and reversing its toxicity in cell cultures was tested. These new tools will allow a follow-up programme to be implemented for sensitized workers, mainly by providing a more precise diagnosis of the determination of their exposure to beryllium. It will also be possible to validate current standards or to define new ones based on firm assumptions.
