Human surfactant is a complex of phospholipids and surfactant-associated proteins, which is essential for life. Surfactant proteins consist of four proteins (A, B, C, D) i.e. SP-A, SP-B, SP-C and SP-D. SP-A and SP-D are members of C-type lectin family and play critical roles of innate immunity and host defense against various microorganisms and other environmental insults; SP-B and SP-C are hydrophobic proteins essential for the life due to lowering surface tension of lung alveoli as well as host defense. The genes of these proteins exist significant genetic variations that cause individual susceptibility to various environmental insults and infectious diseases. We have cloned and identified structural and functional differences of human surfactant protein genetic variants of coding region and the regulatory roles of the non-coding regions (5’-UTR and 3’-UTR) of human surfactant proteins in the mRNA stability and protein expression. Furthermore, we are at the first time generated humanized transgenic mice (which express human surfactant protein gene but without mouse surfactant protein gene) as in vivo tool and then study their function and molecular mechanisms of surfactant proteins, and genetic susceptibility of individuals in response to environmental insults (ozone, ambient particulate matter) exposure and infectious conditions. The findings from our studies demonstrate structural, functional and regulatory differences of human surfactant protein genetic variants that can cause individual susceptibility to pulmonary diseases and infectious diseases, thus providing importantly molecular mechanisms for developing personalized medicine based on genomic profile of the individual
Recently, we focus on the following studies: (1) effects of ambient environmental insults (bacterial and viral pathogens and ambient particulate matter) exposure on surfactant protein dysfunction in vitro and in vivo; (2) the genetic susceptibility of SP-A, SP-B, SP-D to infection and acute lung injury using our humanized transgenic mice; (3) the roles of innate immunity of surfactant collectins (SP-A and SP-D) in the extrapulmonary organs, including kidney, intestine, middle ear, eye and pancreas, in several different disease models; (4) mucosal innate immunity of human SP-A and SP-D genetic variants against SARS-CoV-2 infectivity. In addition, we are developing a project to study of preRNA splicing mechanisms and the role of TP53 gene polymorphisms in the pathogenesis of lung cancer.
