CXCL13 and posterior cortical atrophy: We focused on chemokines associated with CD8+ cell recruitment and found that the expression levels of CCL2, CCL4, CCL5, CCL7, CCL20, CCL23, CXCL5, CXCL6, CXCL9, CXCL10, CXCL13, and CX3CL1 were significantly negatively correlated with SEPT5 expression in PCa (Fig. 6A).
