The increased expression of both CCL24 and CCR3 in the fibrotic liver of patients with PSC, expressed by cholangiocytes and surrounding immune cells and in hepatic fibroblasts within the periductal fibrotic region, suggests that this CCL24/CCR3 axis might be involved in fibrosis progression/severity in patients with PSC. Here, CCL24 is linked to pancreatic serous cystadenoma.
