The fundamentals of activating APOBECs are being worked out by multiple groups across the world. That said, one phrase you'll always read around the APOBEC3 sub-family of proteins (responsible for the anti-HIV effect), is "double-edged sword". The biggest risk, with (cytidine deaminase) enzymes that act on DNA, thereby changing the fundamental genetic code, is causing cancer. More recently, APOBEC3B (no anti-HIV effect, but same sub-family), was shown to have extremely strong correlation with breast cancer[0]! The emerging therapeutic field involving APOBECs will require highly specific targeting of activators(anti-HIV) as well as inhibitors(anti-cancer)[1].
