Fig. 3From: Quantitative proteomics reveals protein dysregulation during T cell activation in multiple sclerosis patients compared to healthy controlsPrincipal component analysis (PCA) of differentially expressed proteins. Scores of the first (PC1) and second (PC2) principal components obtained by PCA of proteins significantly different in abundance (p ≤ 0.05) between MS patients (MS; red circles) and HCs (HC; blue triangles) in (A) unstimulated and (B) stimulated CD4+ T cellsBack to article page
