Therefore, levels of CXCR3 (receptor for CXCL9 and CXCL10), CXCR5 (receptor for CXCL13), CCR5 (receptor for CCL3 and CCL5), and CCR7 (receptor for CCL19) were analyzed on CD45hiCD11bloCD19+ B cells which infiltrated the brain at 7, 14, 30, and 60 days post infection. The gene discussed is CCR7; the disease is infection.
