Subject: CS>Bee venom kills HIV


Bees could hold the key to preventing HIV transmission. Researchers have 
discovered that bee venom kills the virus while leaving body cells unharmed, 
which could lead to an anti-HIV vaginal gel and other treatments.  Scientists 
at 
the Washington University School of Medicine in St. Louis found that melittin, 
a 
toxin found in bee venom, physically destroys the HIV virus, a breakthrough 
that 
could potentially lead to drugs that are immune to HIV resistance. The study 
was 
published Thursday in the journal *Antiviral Therapy*.  "Our hope is that in 
places where HIV is running rampant, people could use  this as a preventative 
measure to stop the initial infection," Joshua Hood, one of the authors of the 
study, said in a statement.  The researchers attached melittin to nanoparticles 
that are physically smaller than HIV, which is smaller than body cells. The 
toxin rips holes in the virus' outer layer, destroying it, but the particles 
aren't large enough to damage body cells.  "Based on this finding, we propose 
that melittin-loaded nanoparticles are well-suited for use as topical vaginal 
HIV virucidal agents," they write.  Theoretically, the particles could also be 
injected into an HIV-positive person to eliminate the virus in the bloodstream. 
 
Because the toxin attacks the virus' outer layer, the virus is likely unable to 
develop a resistance to the substance, which could make it more effective than 
other HIV drugs.  "Theoretically, melittin nanoparticles are not susceptible to 
HIV mutational resistance seen with standard HIV therapies," they write. "By 
disintegrating the [virus'] lipid envelope [it's] less likely to develop 
resistance to the melittin nanoparticles."  The group plans to soon test the 
gel 
in clinical trials.  ...  A new study has shown that bee venom can kill the 
human immunodeficiency virus (HIV).  Researchers at Washington University 
School 
of Medicine in St. Louis have demonstrated that a toxin called melittin found 
in 
bee venom can destroy HIV<http://news.wustl.edu/news/Pages/25061.aspx>by poking 
holes in the envelope surrounding the virus, according to a news release sent 
out by Washington University.  *Visit Washington University's website to read

Nanoparticles smaller than HIV were infused with the bee venom 
toxin<http://www.usnews.com/news/articles/2013/03/08/study-bee-venom-kills-hiv>,
 
explains U.S. News & World Report. A "protective bumper" was added to the 
nanoparticle's surface, allowing it to bounce off normal cells and leave them 
intact. Normal cells are larger than HIV, so the nanoparticles target  HIV, 
which is so small it fits between the bumpers.  “Melittin on the nanoparticles 
fuses with the viral envelope,” said research instructor Joshua L. Hood, MD, 
PhD, via the news release. “The melittin forms little pore-like attack 
complexes 
and ruptures the envelope, stripping it off the virus.” Adding, “We are 
attacking an inherent physical property of HIV. Theoretically, there isn’t any 
way for the virus to adapt to that. The virus has to have a protective coat, a 
double-layered membrane that covers the virus.”  This revelation can lead to 
the 
development of a vaginal gel to prevent the spread of 
HIV<http://www.gaystarnews.com/article/bee-venom-shown-kill-hiv-scientists-reveal080313>and,
 it seems, an intravenous treatment to help those already infected. “Our hope 
is 
that in places where HIV is running rampant, people could use this gel as a 
preventive measure to stop the initial infection,” said Hood.  The bee venom 
HIV 
study was
