Immune infiltrative patterns in TAA and normal conditions. a Histogram of 22 types of immune cells in each TAA and normal tissue. b Violin chart showing the differences in infiltrating immune cells between the two groups. The blue color represents the normal condition and the red color represents the TAA. c Correlation heatmap of all the immune cells. The numbers in the small square represent Pearson’s correlation coefficient between the two immune cells on the horizontal and vertical coordinates. d Principal component analysis (PCA) suggests a difference between TAA and normal thoracic aorta in the composition of infiltrating immune cells, which it might not be significant
