Summary
Mice exposed to intraperitoneal LPS secrete exosomes in Broncho-alveolar lavage (BAL) fluid that are packaged with miRNAs. Using a co-culture system, we show that exosomes released in the BAL fluid disrupt expression of tight junction proteins in bronchial epithelial cells and increase expression of pro-inflammatory cytokines that accentuate lung injury.
