CCR5 and infection: The immunization with cDDR5-conjugated multiple-Ag peptide (cDDR5-MAP) induced long lasting anti-cDDR5 antibodies reacting with both human and macaque CCR5 molecules, which were able to suppress infection by the R5 HIV-1 laboratory isolate (HIV JRFL), R5 HIV-1 primary isolates (clade A:HIV 93RW004 and clade C:HIV MJ4), and a pathogenic simian/HIV (SHIV SF162P3) bulk isolate in vitro.
