Any cure for HIV will unfortunately be years off, due to the latent HIV in resting CD4 cells in many parts of the body - which can still be hanging around 60 years later!
At the moment when these cells “wake up” as they are needed, medication suppresses any virus from multiplying. Finding all these infected cells in their dormant state and either waking them up so the virus in them can be killed is one strategy (kick and kill). Another is to try to stop any infected cell from waking up at all (block and lock). There are many different approaches being tested which is great.
With the stem cell transplant, 3 men have possibly been cured so far (more than 30 who tried the same approach weren’t unfortunately). The primary reason for doing this wasn’t for HIV but for cancer that they all had which would have killed them otherwise. It is an incredibly invasive and expensive procedure which basically wipes out someone’s immune system and not suitable just for clearing of HIV in large numbers.
Some people have a mutation to the co-receptor CCR5. Think of it like a door on the surface of a CD4 cell (white blood cell) and the virus enters through it to infect and multiply. When there is a mutated form of this door the virus can’t get in and do any damage. I think that if a vaccine can be made to confer a genetic immunity like this to everyone this would be brilliant.
Interestingly, a small percentage of people living with HIV are able, like PMG’s son, to suppress the virus without meds. They’re known as Elite Controllers, or Long Term Non Progressors. It could be because of this mutated gene, or something else.
So much is being learnt all the time - it’s quite exciting from a personal perspective. For those of us living with HIV, next steps are long lasting injectibles.
ThatLibraryMiss, I’d be interested in any detail of what double dose immunity your DD has?
