Lentiviral vector-mediated down-regulation of IL-17A receptor in hepatic stellate cells results in decreased secretion of IL-6

Figure 1 Short hairpin RNA design, interference efficiency assay, and lentivirus transduction. A: DNA sequence analysis of pGCSIL/Interleukin-17A receptor (IL-17RA) short hairpin RNA (shRNA) 1; B: Lentiviral-mediated IL-17RA shRNA 1, 2, 3, and 4 (shRNA 1, 2, 3, and 4) inhibited IL-17RA mRNA expression in hepatic stellate cells (HSCs). HSCs infected with lentivirus at a multiplicity of infection of 10 for 72 h, and IL-17RA mRNA expression was quantified by polymerase chain reaction. IL-17RA shRNA 1 was the most efficient silencing tool for IL-17RA. ^bP < 0.01 vs control; C: Cell morphology of HSCs under fluorescence (1) and light (2) microscope after 72 h transduction.
