BTW HIV also mutates and eventually finds a way around CCR5 (X4 tropic). Dr. Sacha noted during one of the CC that all sexually transmitted HIV is CCR5. I'm sure trding or someone can enlighten us on how long or why HIV eventually transforms from R5 to X4 tropic?
If I remember correctly CXCR4 does not exhibit in the mucosal lining which is why CCR5 HIV is the only sexual transmittal vector.
The HIV CXCR4 mutation almost exclusively occurs as a workaround to current HIV drug regimen. I believe there were some very rare cases of CXCR4 HIV occurring naturally in Africa.
