TNF and B-cell chronic lymphocytic leukemia: Our ultimate goal was to investigate changes in the proportion of classical, intermediate, and nonclassical monocytes with intracellular expression of pro- and anti-inflammatory cytokine (TNF and IL-10) and selected miRNA (miR-106a-5p, miR-150-5p, and miR-21-3p) in CLL patients with a high and low value of MLR.
