Despite the high relevance of this problem, influenza pathogenesis and the role of surfactant system and its SP-A (surfactant protein A) enzyme in antiviral defense remain poorly understood. SP-A activates macrophage M1 polarization and triggers an antiviral response due to the activation of T-cells and dendritic cells. Therefore, surfactant system is an important element of infection protection and a promising therapeutic target. %K Influenza A (H1N1) Virus %K Pulmonary Surfactant system %K SP-A %K M1/M2 Macrophages %K Antiviral Defense %U http://www.scirp.org/journal/PaperInformation.aspx?PaperID=62555
