In the study of host–human T-cell leukemia virus type 1 (HTLV-1)-associated adult T-cell leukemia/lymphoma (ATLL), Rahimzada et al. [124] found that compared with asymptomatic carriers of HTLV-1 (ACs), CXCR3 expression was significantly decreased in ATLL patients. Here, CXCR3 is linked to adult T-cell leukemia/lymphoma.
