CCR1 and Huntington disease: Compared to untreated viral-infected cells, during the early stages of HD treatment (6 m p.t) in viral-infected cells, CCR1 (1.7-fold, p = 0.01), CCL26 (1.6-fold, p = 0.004), and CCL15 (1.6-fold, p = 0.02) were repressed (Figure 6, Table 4); CCL5 (2615.1-fold, p = 0.0006), IL21 (2.4-fold, p = 0.0002), and IL17C (3.7-fold, p = 0.03) were downregulated at 6 h p.t. CCL5 displayed the greatest repressed expression levels.
