Both CD11b and CD18 integrin subunits were significantly upregulated on Mo1 monocytes from HD patients compared to healthy controls (Table 1, Fig. 1B,C; CD11b CON/HD pre: p = 0.001, CON/HD post: p < 0.0001, HD pre/post: p = 0.02; CD18 CON/HD pre: p = 0.005, CON/HD post: p = 0.003, HD pre/post: p = 0.6). This evidence concerns the gene ITGAM and Huntington disease.
