S100A8 and systemic lupus erythematosus: The aim of this study is to assess the gene expression levels of intracellular kinases AKT1 and MAPK1 in peripheral blood mononuclear cells (PBMC) from SLE patients with inactive or mild disease and to analyze whether there was any correlation with Th-transcription factors gene expression, with gene expression and plasma levels of a comprehensive panel of cytokines (Th0-, Th1/Th17-, and Th2/Treg-type), with plasma inflammation mediators S100A8/A9-Calprotectin and clinical parameters.
