doi: 10.3389/fimmu.2023.1182842
Figure Lengend Snippet: Lectin array profiling of serum samples from Hashimoto′s thyroiditis (HT) patients (n=27) and healthy control (HC) (n=26). (A) Representative results of the array profiling for HT (left) and HC (right) groups. Red boxes indicate the position of lectins with the significant difference between groups. (B) Principal component analysis (PCA) of the mean normalized signals obtained from lectin microarray. A scatter plot for principal component (PC) 1 and 2 is shown. Each dot represents the sample derived from an individual person. Different groups are indicated by color. (C) Volcano plot of log2 fold change (x axis) in lectin binding signals of HT samples vs . HC samples against the significance of change shown as the −log10 p-value (y axis). Red and green dots indicate lectins with up-regulated and down-regulated binding signals, respectively. (D) Heat map and hierarchical clustering of lectin microarray signals. Each column represents samples from an individual person. Thirteen lectins are shown on rows. (E) The binding signal of 14 lectins shows a significant difference between groups. *p <0.05, **p <0.01, ***p <0.005 and ****p <0.001.
