Increased miR-150 decreases neutrophil counts and production of inflammatory cytokines IL-1β, IL-6, and TNF-α along with levels of total protein, albumin and IgM in the BAL fluid in LPS-induced acute lung injury mice in vivo, as well as alleviating LPS-induced A549 cell apoptosis in vitro [27]. Here, IL1B is linked to acute lung injury.
