PM 2.5 or the PM 2.5 toxin B[a]P initially acts as an irreversible β2AR agonist to hyperactivate the PI3K signaling pathway. PLC, acting on PIP2, releases DAG. DAG activates the TRPC6 channel to bring extracellular Ca +2 into the cell. Increased Ca +2 is taken up by mitochondria, which release Reactive Oxygen Species (ROS) and contribute to oxidative stress. BI 749327 can block TRPC6 channel activity and suppress oxidative stress. Meanwhile, hyper-activation of β2AR leads to endosomal β2AR loss, followed by endosomal loss of CFTR (-). Loss of CFTR results in (i) activation of TRADD and downstream activation of IKKαβ to drive NFκB; and (ii) further activation of CFTR-bound TRPC6. NFκB enters the nucleus and drives expression of proinflammatory cytokines IL8 and IL6. Both TRADD and PI3K pathways may be required for optimal NFκB activation, because LY294002 can block inflammation.
