While it has been shown that CXCL10 is higher in patients with CCC, and polymorphisms in CXCL9 and CXCL10 are responsible for their altered expression patterns (Nogueira et al., 2012), CXCR3 expression on CD8+ cells is inversely proportional to the intensity of myocarditis (Roffe et al., 2019). This evidence concerns the gene CXCL9 and myocarditis.
