Reduced influenza viral neutralizing activity of natural human trimers of surfactant protein D
Abstract Background Surfactant protein D (SP-D) plays important roles in innate host defense against influenza A virus (IAV) infection.Common human polymorphisms of SP-D have been found in many human populations and associated with increased risk of certain infections.We recently reported that the Thr/Thr 11 form of SP-D is associated with low seru
