Expression And Functions Of Il-24 And Socs3 In Pseudomonas Aeruginosa Keratitis In A C57bl/6 Mouse Model, Bing Xu
Wayne State University Dissertations
The aim of this study was to elucidate the expression and functions of interleukin (IL)-24 and suppressor of cytokine signaling 3 (SOCS3), and their regulatory relationship in C57BL/6 mouse corneas in response to Pseudomonas aeruginosa (PA) infection. Among IL-20R cytokines, only IL-24 was induced at both mRNA and protein levels by the infection, and this upregulation was dampened by flagellin pretreatment. Time course studies revealed that IL-24 expression was markedly elevated, followed by a subsidence and second elevation, a pattern shared with SOCS3 but not IL-1β or IL-6. Silencing of IL-24 enhanced S100A8/A9 expression, and suppressed SOCS3, IL-1β, IL-1RN, and …
