Transcriptome Analysis to Characterize the Immune Response of NecroX-7 in Mouse CD4⁺ T Cells

NecroX-7 is a novel small compound of the NecroX series based on the indole moiety, which has potent cytoprotective and antioxidant properties. We previously detected potential immune regulatory effects of NecroX-7 in immune related diseases like Graft-versus-Host Disease. However, the function and the underlying mechanisms of immunological effects of NecroX-7 in the immune system have not been well established. In this study, we investigated the immune response characterization of differentially expressed genes of NecroX-7 administration in $CD4^+$ T cells by microarray analysis. $CD4^+$ T cells stimulated with NecroX-7 ($40{\mu}M$) or vehicle for 72 hours resulted in the identification of 337 differentially expressed genes (1.5 fold, P<0.05) by expression profiling analysis. Twenty eight of the explored NecroX-7-regulated genes were related to immune system processes. These genes were validated by quantitative real-time PCR. The most significant genes were glutathione reductase, eukaryotic translation elongation factor 1, lymphotoxin-alpha, heat shock protein 9 and chloride intracellular channel protein 4. These findings demonstrate the strongly immune response of NecroX-7 in $CD4^+$ T cells, suggesting that cytoprotection and immune regulation may underlie the critical aspects of NecroX-7 exposure.
