A Multiparametric flow cytometry analysis of bone marrow cells. Automatic population separator (APS) plot provided the best cell cluster separation, to confirm the identity of CD4+ and CD8+ T cells. Grey color: other nucleated populations. B Human Phospho-kinase Array. Levels of phosphorylated proteins were quantified with Kodak Molecular Imaging Software version 2.0.0 (Eastman Kodak Co., Rochester, NY). A and B representative cases of 6 independent experiments from idiopathic aplastic anemia and benign anemia cases. C The finding of the heterozygous variant (p.520T>C, p.Cys174Arg) in the coiled-coil domain of STAT1 gene, showing gain of function (GOF) activity paved the way for idiopathic aplastic anemia cases investigation. A boosted STAT1 pathway activation unleashes a Th1 phenotype differentiation, driving a variable clinical phenotype, including bone marrow failure. Created with BioRender.com, Publication license n.
