CD4 and systemic lupus erythematosus: Next, we examined the SLE immune gene sets (i.e. immune gene sets in SLE samples derived from the C7 immunologic signature gene sets of MSigDB collections) associated with gp130 expression at the transcript levels (i.e. IL6ST gene) through GSEA of a GEP dataset of CD4+ T cells isolated from SLE patients (n=8; GSE4588).
