When comparing to control subjects, the expression levels of CC chemokines CCL3 (P = 0.043), CCL4 (P = 0.034), CCL5 (P < 0.001), and CCL8 (P = 0.031) and CXC chemokines CXCL9 (P < 0.001), CXCL10 (P = 0.002), and CXCL11 (P = 0.008) were found to be elevated in sarcoidosis patients (Table 3, Figure 1(b)). This evidence concerns the gene CCL4 and sarcoidosis.
