ABSTRACT Chronic lymphocytic leukemia (CLL) is frequently associated with autoimmune hemolytic anemia (AIHA). However, the mechanisms governing the association between CLL and AIHA are poorly understood. miRNAS have been associated with different clinico-biological forms of CLL and are also known to play a substantial role in autoimmunity. However, there are no studies correlating miRNAs expression with the likelihood that patients with CLL will develop AIHA. In this study, we found that malignant B- cells from patients with CLL subsequently developing AIHA present nine downregulated (i.e., miR-19a, miR-20a, miR-29c miR-146b-5p, miR-186, miR-223 miR-324-3p, miR-484 and miR-660) miRNAs. Interestingly, two of these miRNAs (i.e., miR-20a and miR-146b-5p) are involved in autoimmune phenomena, and one (i.e., miR-146b-5p) in both autoimmunity and CLL. Furthermore, we demonstrate that miR-146b-5p modulates CD80, a molecule associated with the B-T-cell synapse and in restoring the antigen presenting capacity of CLL cells.
