Effect of NIK overexpression on Foxp3+CD4+ and Foxp3-CD4+ T cell subsets [Illumina]

We previously found that NF-kB inducing kinase (NIK) overexpression in T cells via CD4 promoter driven transgene induction caused lethal autoimmunity in mice. Autoimmunity was associated with increased conventional T cell effector function and decreased regulatory T cell (Foxp3+CD4+) suppression. The goal in this study was to elucidate global transcriptional changes in Foxp3+CD4+ and Foxp3-CD4+ T cells intrinsically caused by chronic NIK overexpression in these cell types.
