                 CCR3 and CCR5 are Co-Receptors for HIV-1
                 Infection of Microglia

                 He, Jianglin; Chen, Youzhi; Farzan, Michael; et al.

                 The three chemokine co-receptors known to be involved in
HIV-1
                 infection--CCR5, CXCR4, and CCR3--are found in various
types of cells and
                 tissues. Resistance to HIV-1 infection has been linked to
defective CCR5
                 alleles, suggesting that CCR5 plays an important role in
HIV-replication in the
                 body. In the central nervous system (CNS), HIV-1 targets
brain cells known
                 as microglia and causes AIDS-related dementia. Researchers
now report that
                 these target cells express both CCR3 and CCR5. The
researchers found that
                 the CCR3 ligand, eotaxin, and an anti-CCR3 antibody
inhibited HIV-1
                 infection in the brain cells, as did a CCR5 ligand. The
authors suggest that both
                 co-receptors promote HIV-1 infection of the CNS and that
the identification of
                 CCR3's role in the infection of microglia may lead to new
treatments for
                 AIDS-related dementia.
