Prehistoric Gene Reawakened To Battle HIV

Linuss points out research published in PLoS Biology that demonstrates the reawakening of latent human cells' ability to manufacture an HIV defense. A group of scientists led by Nitya Venkataraman began with the knowledge that Old World monkeys have a built-in immunity to HIV: a protein that can prevent HIV from entering cell walls and starting an infection. They examined the human genome for any evidence of a latent gene that could manufacture such a protein, and found the capability in a stretch of what has been dismissively termed "junk DNA." "In this work, we reveal that, upon correction of the premature termination codon in theta-defensin pseudogenes, human myeloid cells produce cyclic, antiviral peptides (which we have termed 'retrocyclins'), indicating that the cells retain the intact machinery to make cyclic peptides. Furthermore, we exploited the ability of aminoglycoside antibiotics to read-through the premature termination codon within retrocyclin transcripts to produce functional peptides that are active against HIV-1. Given that the endogenous production of retrocyclins could also be restored in human cervicovaginal tissues, we propose that aminoglycoside-based topical microbicides might be useful in preventing sexual transmission of HIV-1."

    AIDS is pwned. Good for us and our "junk" DNA. One man's junk is another man's treasure!

    We reactivated this gene in the lab, and it seemed to work. There's a type of antibiotic that seems to reactivate the gene as well. So applying the antibiotic topically (read "like spermicidal foam/gel) should reactivate the gene in a woman's naughtybits and so fight the virus.

    Focused on the woman - good idea. But how does science focus on the man? How about "STOP FUCKING PEOPLE WHO AREN'T YOUR WIFE/GIRLFRIED/SIGNIFIGANT OTHER!"

      Men were not made for monogamy, your stupid culture made you believe so.
