CD68 and Melnick-Needles syndrome: The levels of CD68 and CD163 protein in the ventricular samples were significantly higher in the MNS group 2 than in the control group (CD68: 4.98 ± 0.23 vs. 1.88 ± 0.26, P < 0.01; CD163: 4.83 ± 0.26 vs. 1.67 ± 0.22, P < 0.01) and in the MNS group 1 (CD68: 4.98 ± 0.23 vs. 3.07 ± 0.18, P < 0.01; CD163: 4.83 ± 0.26 vs. 3.1 ± 0.24, P < 0.01).
