Not *this* antibody, but other SUPER AWESOME ANTIBODIES OMFG BREAKTHROUGH!
Your adaptive immune system operates by, what I would call, picoevolution. It is chance + random mutations + natural selection.
Lets say both you and I get infected with the exact same variant of swine flu. We both fight it off successfully, and generate a potent neutralizing antibody response to swine flu. My neutralizing antibodies are nothing like your neutralizing antibodies. Chance, randomization, and selection led to different ‘answers’ to swine flu in both of us… and everyone else infected with swine flu.
Lets say you and I both got the swine flu vaccine last year, thus we never got sick. The antibodies my body generated to the vaccine are nothing like the antibodies your body generated to the vaccine– even if we are both equally protected. Chance, randomization, and selection led to different reactions to the swine flu vaccine in both of us… and everyone else that got the vaccine.
But lets say, by chance, my body generated an antibody that neutralized 100% of all influenzas. I would never get the flu ever ever ever again. There is no way to force anyone elses body to create that antibody. The patients who they isolate these super awesome antibodies from? They have had HIV-1 for a long time. Which means there have been many many many rounds of chance, randomization, selection, chance, randomization, selection, chance, randomization, selection. You cant get these kinds of antibodies from a vaccine, which are normally one hit (proteins), one round (pseudoviruses, dummy viruses). Live attenuated viruses are never going to happen with HIV-1. There is just no way to make people make this antibody, no matter how awesome it is… short of gene therapy:
Finally, there are experimental methods that employ tactics such as gene therapy. Nobel laureate David Baltimore, with funding from the Bill and Melinda Gates Foundation, is working on one such approach.
His team at the California Institute of Technology in Pasadena, Calif., has stitched genes that code for antibodies into a harmless virus, which they then inject into mice. The virus infects mouse cells, turning them into factories that produce the antibodies.
That isnt exactly a viable option in most cases, or with most people at risk for HIV-1 infection.
The best use of this antibody I see is one they already thought of– Put the antibody in spermacides/microbicides.
The antibody could also be tested in a “microbicide,” a gel that women and receptive partners in gay male pairings could apply before sex to prevent infection.
A big problem with HIV-1 vaccines is, sure you might make great anti-HIV antibodies or anti-HIV cytotoxic T-cells– but they have to be in the right place at the right time. If the anti-HIV CTLs arent hanging out at the site of infection, and HIV gets a foothold, youre still screwed. But putting this antibody AT the site of infection would be the way to go.
But still, no, super awesome antibodies arent a cure for HIV/AIDS.
