We generated multiple data set from well-defined patients with SS, which includes whole-blood transcriptomes, serum proteomes and peripheral immunophenotyping. Based on our newly generated data, we performed an extensive bioinformatic investigation. Our integrative analysis identified SS gene signatures (SGS) dysregulated in widespread omics layers, including epigenomes, mRNAs and proteins. SGS predominantly involved the interferon signature and ADAMs substrates. Besides, SGS was significantly overlapped with SS-causing genes indicated by a genome-wide association study and expression trait loci analyses. Combining the molecular signatures with immunophenotypic profiles revealed that cytotoxic CD8 ­T cells­ were associated with SGS. Further, we observed the activation of SGS in cytotoxic CD8 T cells isolated from patients with SS. Our multi-omics investigation identified gene signatures deeply associated with SS pathology and showed the involvement of cytotoxic CD8 T cells. These integrative relations across multiple layers will facilitate our understanding of SS at the system level.\"\n", "!Series_overall_design\t\"The peripheral CD4 T-cell subsets in four major differentiation stages, naive CD4 T-cells (TN), central memory CD4 T-cells (TCM), effector memory CD4 T-cells (TEM), from six pSS patients and six healthy controls were subjected to genome-wide transcriptome arrays.\"\n", "Sample Characteristics Dictionary:\n", "{0: ['disease: HC', 'disease: pSS'], 1: ['celltype: naive CD4', 'celltype: central memory CD4', 'celltype: effector memory CD4'], 2: ['patient: HC-26', 'patient: HC-31', 'patient: HC-J', 'patient: HC-K', 'patient: HC-M', 'patient: HC-N', 'patient: K9576', 'patient: K3797', 'patient: K1017', 'patient: K9008', 'patient: K3775', 'patient: K7734'], 3: ['gender: Female']}\n" ] } ], "source": [ "from tools.preprocess import *\n", "# 1.
