Another study on CCR7 showed that surface CCR7 levels on B cells measured by flow cytometry did not differ between mutated chronic lymphocytic leukemia (M-CLL) versus un-mutated CLL (U-CLL) patients, while the transcripts and total CCR7 protein levels were significantly increased in U-CLL cells compared to those in M-CLL [14]. The gene discussed is CCR7; the disease is B-cell chronic lymphocytic leukemia.
