  • Targeted drug delivery with these nanoparticles can make medicines more effective
    developed to cloak nanoparticles in red blood cell membranes The researchers previously demonstrated that nanoparticles disguised as red blood cells are capable of removing dangerous pore forming toxins produced by MRSA poisonous snake bites and bee stings from the bloodstream By using the body s own platelet membranes the researchers were able to produce platelet mimics that contain the complete set of surface receptors antigens and proteins naturally present on platelet membranes This is unlike other efforts which synthesize platelet mimics that replicate one or two surface proteins of the platelet membrane Our technique takes advantage of the unique natural properties of human platelet membranes which have a natural preference to bind to certain tissues and organisms in the body said Zhang This targeting ability which red blood cell membranes do not have makes platelet membranes extremely useful for targeted drug delivery researchers said Platelet copycats at work In one part of this study researchers packed platelet mimicking nanoparticles with docetaxel a drug used to prevent scar tissue formation in the lining of damaged blood vessels and administered them to rats afflicted with injured arteries Researchers observed that the docetaxel containing nanoparticles selectively collected onto the damaged sites of arteries and healed them When packed with a small dose of antibiotics platelet mimicking nanoparticles can also greatly minimize bacterial infections that have entered the bloodstream and spread to various organs in the body Researchers injected nanoparticles containing just one sixth the clinical dose of the antibiotic vancomycin into one of group of mice systemically infected with MRSA bacteria The organs of these mice ended up with bacterial counts up to one thousand times lower than mice treated with the clinical dose of vancomycin alone Our platelet mimicking nanoparticles can increase the therapeutic efficacy of antibiotics because they can focus treatment on the bacteria locally without spreading drugs to healthy tissues and organs throughout the rest of the body said Zhang We hope to develop platelet mimicking nanoparticles into new treatments for systemic bacterial infections and cardiovascular disease Explore further Shape of things to come in platelet mimicry More information Nanoparticle biointerfacing by platelet membrane cloaking by Che Ming J Hu Ronnie H Fang Kuei Chun Wang Brian T Luk Soracha Thamphiwatana Diana Dehaini Phu Nguyen Pavimol Angsantikul Cindy H Wen Ashlev V Kroll Cody Carpenter Manikantan Ramesh Vivian Qu Sherrina H Patel Jie Zhu William Shi Florence M Hofman Thomas C Chen Weiwei Gao Kang Zhang Shu Chien and Liangfang Zhang This paper is published Sept 16 2015 online in Nature DOI 10 1038 nature15373 Journal reference Nature Provided by University of California San Diego 2623 shares feedback to editors Tweet Favorites Email Print PDF Featured Last comments Popular Detection of gravitational waves would open new window on universe Feb 10 2016 58 Gravitational waves detected 100 years after Einstein s prediction Feb 11 2016 144 GPS tracking down to the centimeter Feb 11 2016 10 A metal that behaves like water Feb 11 2016 2 Physicists create first photonic
