CXCR3 and bile duct papillary neoplasm: The expression levels increased approximately 9 times for cxcl9, 300 times for cxcl-10, 692 times for cxcl11, and 93 times for cxcr3 (Figure 10), demonstrating that IPN viral infection can induce the expression of these chemokines and their receptor in Atlantic salmon probably to control cellular homing.
