Participants included 155 IAV patients . Samples from healthy individuals were randomly selected as controls from the local blood donation center. As shown in Table 1 and Table 2, the main clinical and demographic characteristics of the population were presented in this study. Written informed consents were obtained from all patients. This study was approved by the Ethics Committee and was performed according to the Declaration of Helsinki Principles.
The influenza virus strain A/chicken/Hubei/327/2004 (H5N1) used in this study was provided by China Center for Type Culture Collection (CCTCC). Stock virus was propagated in 10-day-old embryonated chicken eggs for 36 to 48 h at 37 °C. The allantoic fluid was then harvested, and aliquots were stored at -80°C before being used. Mammalian expression plasmids for IL-22 and IL-34 were constructed by standard molecular biology techniques.
PBMCs were isolated from venous blood from healthy individuals. PBMC fractions were obtained by density centrifugation using Histopaque as per the manufacturer’s instructions (Sigma, St. Louis, MO). PBMCs were transfected with plasmid DNA by electroporation with an Amaxa Nucleofector II Device according to the manufacturers’ protocols.
