Immature DCs express the chemokines CCR1, CCR2, CCR5, CCR6, and CXCR1 [86,87], thereby facilitating the arrival at the site of inflammation, infection and being able to recognize chemo-attractants, such as MIP-3 alpha/CCL20, RANTES/CCL5 and MIP-1 alpha/CCL3 [88]. The gene discussed is CCL5; the disease is infection.
