    2024/10/02 | National Institute for Occupational Safety and Health (NIOSH)
    Exposure to 4,4'-methylene diphenyl diisocyanate (MDI) in the workplace may lead to the development of occupational asthma (OA). However, the specific mechanism(s) by which MDI induces OA are poorly understood. Previous reports have demonstrated that MDI and MDI-glutathione (GSH) conjugate exposure downregulates endogenous human/murine (hsa/mmu)-mi ...
