Immune checkpoint PDCD1 mRNA expression and correlation in T Effector response to LL-37 and cat-hCAP-18. Programmed cell death protein 1 (PDCD1) mRNA expression in peripheral blood mononuclear cells stimulated with the human antimicrobial peptide LL-37 (A) or the cathelin domain of the proprotein hCAP-18, cat-hCAP-18 (B). Control N = 6; Stable = 5; ACS = 5. *P < 0.05 (ACS vs Control; Kruskal-Wallis and Dunn’s multiple comparisons test). Correlation plot between CD8+ T Effector response to LL-37 and cat-hCAP-18 (C). Correlation plot between CD4+ T Effector response to LL-37 and cat-hCAP-18 (D).
