Despite the fact that flow cytometry data from our clinical cohort suggested that only a negligible fraction of U-CLL cases shows high expression of SLAMF1 or SLAMF7 receptors (1 of 27 U-CLL cases, as shown in Fig. 1d), we sought to explore SLAMF1 and SLAMF7 overexpression in a U-CLL cellular context (Hg3). The gene discussed is SLAMF7; the disease is B-cell chronic lymphocytic leukemia.
