Attachment of HIV to a CD4+ T-helper cell: 1) the gp120 viral protein attaches to CD4. 2) gp120 variable loop attaches to a coreceptor, either CCR5 or CXCR4. 3) HIV enters the cell.
C-C chemokine receptor type 5 , also known as CCR5 or CD195 , is a protein on the surface of white blood cells that is involved in the immune system as it acts as a receptor for chemokines .[ 5]
In humans, the CCR5 gene that encodes the CCR5 protein is located on the short (p) arm at position 21 on chromosome 3 . Certain populations have inherited the Delta 32 mutation, resulting in the genetic deletion of a portion of the CCR5 gene. Homozygous carriers of this mutation are resistant to infection by macrophage-tropic (M-tropic) strains of HIV-1 .[ 6] [ 7] [ 8] [ 9] [ 10] [ 11]
