Nucleotide-binding oligomerization domain-like receptor containing pyrin domain 3 (NLRP3) plays a key role in lung injury diseases regulation, and its expression is increased in lung injury diseases. NLRP3 may be a good therapeutic target for lung injury diseases. The molecular mechanisms of NLRP3 in lung injury diseases remain unclear. It is a key to study the potential mechanism of NLRP3 during lung injury diseases, so that to exploit it as a good target for lung injury diseases therapy.
