To the best of our knowledge this study is the first addressing expression of CXCL1, CXCL10 and CXCL12 and their receptors in BMT received AML patients, however, it has been shown that most often AML cells constitutively produce the chemotactic chemokines such as CXCL10 and CCL5. The gene discussed is CCL5; the disease is acute myeloid leukemia.
