Modulation of Lymphocyte Proliferation by Antioxidants in Chronic Beryllium Disease
|
Rationale: Occupational exposure to beryllium (Be) can result in chronic granulomatous inflammation characterized by the presence of Be-specific CD4^sup +^ T cells. Studies show that oxidative stress plays a role in the pathogenesis of chronic inflammatory disorders.
Objectives: We hypothesized that Be-induced oxidative stress modulates the proliferation of Be-specific CD4^sup +^ T cells.
Methods: Thirty-three subjects with chronic beryllium disease (CBD), 15 subjects with beryl...
