Ccl6, which shows a slight bi-modal expression and is clearly expressed prior to the other Ccl genes, is involved in myeloid cell differentiation; thus, this chemokine appears to be expressed in concert with Cxcl16. Although our microarray data do not match perfectly with the results reported by Delaleu and colleagues [42], it must be remembered that the latter study was carried out with fluids obtained from NOD mice predisposed for three autoimmune diseases: SjS, T1D, and possibly thyroiditis. Here, CXCL16 is linked to autoimmune disease.
