NFKB1 and acute respiratory distress syndrome: The negative relation between miR-30b-3p and TNF-α, NF-κB, IL-6, and IL-8 levels in the lung tissue and BALF in murine ALI models, as shown by Zhou et al. [148], signifies that the induced protective effects of MSC-exosomal miR-30b-3p are possibly achieved by downregulation of NF-κB and proinflammatory cytokines in experimental models.
