The increases in mRNA expressions of inflammatory cytokines by adding cleaning solvent or tetrachloroethylene in the murine macrophage cell line J774.1 evaluated by real-time PCR.

The use of a petroleum-derived cleaning solvent for dry cleaning, instead of tetrachloroethylene (perchloroethylene, PCE), has increased. The cleaning solvent may induce immunological alteration. In this study, murine macrophage-lineage J774.
