The highest numbers were detected in the groups of pure BBS and of the BBS combined with the low concentration of HY, which were both significantly higher (* p < 0.05 and ** p < 0.01) compared to the number of CD163-positive macrophages in the control group (54.15 ± 35.24 cells/mm2) (Figure 3). This evidence concerns the gene CD163 and Bardet-Biedl syndrome.
