Other chemokines involved in the stimulation and activation of T cells in lymphoid tissue (Cxcl1, Cxcl2, Cxcl9, and Cxcl20, Ccl2, Ccl5, Ccl6, Ccl7, Ccl8, Ccl9, Ccl11, and Ccl29) and chemokine receptors (Ccr1 and Ccr5) were elevated in the skin of mice during acute GvHD (99). This evidence concerns the gene CXCL9 and graft versus host disease.
