Rawf 336 Posted March 31, 2013 Nanoparticles carrying a toxin found in bee venom can destroy human immunodeficiency virus (HIV) while leaving the surrounding cells unharmed. The research was conducted by the Washington University School of Medicine in St. Louis. The Nanoparticles carry melittin, which is the principal active component of bee venom. Melittin fuses with the HIV virus and destroys it’s protective envelope while molecular bumpers prevent the nanoparticles from harming the body’s normal cells. Bee venom is known to disrupt cellular walls and destroy tumour cells as well. Bee venom contains a potent toxin called melittin that... http://www.collective-evolution.com/2013/03/13/bee-venom-destroys-human-immunodeficiency-virus-hiv/ Extremely interesting to read. 4 christmastree77, Gezinha, amor and 1 other reacted to this Share this post Link to post Share on other sites
roadrunner11 167 Posted March 31, 2013 Sweet thank for sharing. This is intersting because it is not a retrovirus but more of a preventive method. I hope people don't get the wrong idea that this is the cure for it. 1 Rawf reacted to this Share this post Link to post Share on other sites

Santi 353 Posted April 18, 2013 Here is a similar story... Also very interesting! MIAMI, April 16, 2013 /PRNewswire-USNewswire/ -- In a study published in today's issue of Nature Communications, researchers from Florida International University's Herbert Wertheim College of Medicine describe a revolutionary technique they have developed that can deliver and fully release the anti-HIV drug AZTTP into the brain. Madhavan Nair, professor and chair, and Sakhrat Khizroev, professor and vice chair of the HWCOM's Department of Immunology, used magneto-electric nanoparticles (MENs) to cross the blood-brain barrier and send a significantly increased level of AZTTP--up to 97 percent more --to HIV-infected cells. For years, the blood-brain barrier has stumped scientists and doctors who work with neurological diseases. A natural filter that allows very few substances to pass through to the brain, the blood-brain barrier keeps most medicines from reaching the brain. Currently, more than 99 percent of the antiretroviral therapies used to treat HIV, such as AZTTP, are deposited in the liver, lungs and other organs before they reach the brain. "This allows a virus, such as AIDS, to lurk unchecked," said Nair, an HIV/immunology researcher. The patent-pending technique developed by FIU binds the drug to a MEN inserted into a monocyte/macrophage cell, which is then injected into the body and drawn to the brain. Once it has reached the brain, a low energy electrical current triggers a release of the drug, which is then guided to its target with magnetoelectricity. In lab experiments, nearly all of the therapy reached its intended target. It will soon enter the next phase of testing. For visuals please click here. Potentially, this method of delivery could help other patients who suffer from neurological diseases such as Alzheimer's, Parkinson's, epilepsy, muscular dystrophy, meningitis and chronic pain. It could also be applicable to diseases such as cancer. "We see this as a multifunctional therapy," said Khizroev, who is an electrical engineer and physicist by training. Multi-disciplinary efforts that combine principles of those fields with immunology enabled the project to move forward. "The success of our nanotechnology is derived from the fact that nature likes simplicity," Khizroev said. source: http://www.freshnews.com/news/785697/new-technique-deliver-life-saving-drugs-brain Share this post Link to post Share on other sites
