The correlation between PCSK9 and immune checkpoints in AAA neck and donor tissues. (A) Spearman’s correlation analysis of the expression data from GSE47472 showed that PCSK9 was negatively related to CTLA4. Spearman’s Rank Correlation Coefficient (Spearman r =  − 0.4816, p = 0.0232). (B) Spearman’s correlation analysis of the expression data from GSE47472 showed PCSK9 was negatively related to LAG3 (Spearman r =  − 0.4308, p = 0.0453). (C) Spearman’s correlation analysis of the expression data from GSE47472 showed PCSK9 was positively related to PDCD1LG2 (Spearman r =  − 0.4308, p = 0.0453).
