This subproject is one of many research subprojects utilizing the resources provided by a Center grant funded by NIH/NCRR. The subproject and investigator (PI) may have received primary funding from another NIH source, and thus could be represented in other CRISP entries. The institution listed is for the Center, which is not necessarily the institution for the investigator. Chronic Beryllium Disease is caused by an immune response to inhaled beryllium, and occurs in 1 to 5% of the beryllium worker population. A critical feature of CBD is hypersensitivity to beryllium. Beryllium hypersensitivity is typically assayed in vitro using lymphocytes isolated from peripheral blood samples and thymidine incorporation. We have developed a flow cytometry assay for the analysis of blood lymphocyte subset proliferation in response to a challenge with soluble beryllium. The test, called the Immuno-LPT (Lymphocyte Proliferation Test) combines BrDU uptake or cell cycle analysis with immunophenotyping in the same assay. The primary target for beryllium sensitivity is the CD4+ cell population. The Immuno-LPT has been. has been validated using peripheral blood samples from patients diagnosed with Chronic Beryllium Disease. In collaboration with Environmental Safety and Health Division, the Immuno-LPT is being applied to screen the LANL beryllium worker cohort and other beryllium worker cohorts in the DOE system for hypersensitivity to beryllium.
