Cover Story: Dendritic cells (DCs) are crucial for antiviral defence through nucleic acid sensing in endosomal compartments. In this study, we show that sub-toxic exposure to diesel exhaust particles and PM2.5 does not induce cytotoxicity; however, these particles accumulate within DCs. The reduced uptake of fluorescent tracer particles indicates diminished endocytic and phagocytic activity under these exposure conditions. Additionally, induction of TLR7-dependent interferon-related genes in response to virus-like stimulation is suppressed. These findings indicate that even non-lethal levels of particulate matter can impair immune function by disrupting cellular uptake mechanisms and innate immune signalling, highlighting an overlooked immunotoxic risk associated with chronic low-dose exposure.
