&nbsp; &nbsp; &nbsp;<em> &nbsp; &nbsp; &nbsp; (courtesy of&nbsp;Wyss Institute at Harvard University)</em></p> <p>The team published a proof-of-principle paper in<em> <a href="http://www.cell.com/cell/fulltext/S0092-8674(16)31246-6">Cell</a> </em>that details the&nbsp;development of&nbsp;a drug manufacturing system that's able to produce on-site, on-demand therapeutics and biomolecules.&nbsp;</p> <p>鈥淚n essence, it鈥檚 like having a portable pharmacy that you can use to create the medications you need,鈥 said Assistant Professor <strong>Keith Pardee</strong> of 老司机直播鈥檚 Faculty of Pharmacy, co-lead author of the paper.&nbsp;</p> <p>Most vaccines need to maintain a consistent temperature to prevent spoilage and maintain their efficacy, which necessitates a cold chain from production to application.&nbsp;</p> <p>Despite these precautions and the attention paid to their transportation, the World Health Organization and United Nations Children鈥檚 Fund estimate that the amount of essential vaccines that end up wasted could be as high as 50 per cent.&nbsp;</p> <p><img alt class="media-image attr__typeof__foaf:Image img__fid__2071 img__view_mode__media_original attr__format__media_original" src="/sites/default/files/Pardee_0863-embed.jpg" style="width: 480px; height: 320px; margin-left: 135px; margin-right: 135px;" typeof="foaf:Image"></p> <p>The first of the freeze-dried pellets, developed by the researchers in 2014, is an innovative cell-free synthetic biology 鈥渕achinery鈥 that provides the manufacturing infrastructure to create an end product.&nbsp;</p> <p>The second pellet consists of&nbsp;DNA instructions that tell the manufacturing piece what compound to produce. This pellet can be customized to generate a variety of products, including vaccines, anti-cancer antibodies, and diagnostic tools.&nbsp;</p> <p>When the two freeze-dried pellets are combined with water, the production process begins.&nbsp;</p> <h3><a href="/news/rapid-low-cost-detection-zika-virus-developed-experts-u-t-harvard-mit-cornell-and-more">Read more about the team's earlier research on a low-cost Zika virus detection system</a></h3> <p>Through the simple act of rehydrating the components by adding water, vaccines, antibody-based drugs for cancer treatment, small molecules, and clinical tools like diagnostic systems spring to life, bringing tools and treatments to underserved populations.&nbsp;</p> <p>The possible applications for this discovery, Pardee explains, are almost endless.&nbsp;</p> <p>鈥淚f, for example, the influenza vaccine developed in a given year is off target and doesn't fight the strains of the virus that emerge, the system we鈥檝e developed can address that,鈥 he said. 鈥淭he current production chain for the influenza vaccine begins in late spring early summer for fall and winter application. If the formula is wrong, it would take months to change, produce, ship, and administer a vaccine that hits on the right strains.</p> <p>鈥淲hereas with our system, in theory, once the proper strains are identified and a new formula developed, the vaccine could be produced anywhere in a matter of hours. The materials would already be on the shelf 鈥&nbsp;they鈥檇 just need to be programmed to produce the vaccine. While this is just a proof-of-concept study, this could mean no prolonged production time, no timely and expensive shipping.鈥</p> <p>These freeze-dried pellets last for at least a year at room temperature, making shipping and storage easy and considerably less expensive than traditional means 鈥&nbsp;even to the most remote areas. It also means that the products can be stored on the shelf, ready to be activated when an outbreak occurs or whenever the need arises.</p> <p><img alt class="media-image attr__typeof__foaf:Image img__fid__2072 img__view_mode__media_original attr__format__media_original" src="/sites/default/files/Biomolecular%20Manufacturing%20002%20%285%29.gif" style="width: 480px; height: 270px; margin-left: 135px; margin-right: 135px;" typeof="foaf:Image"><br> &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;<em> &nbsp;(courtesy of Wyss Institute at Harvard University)&nbsp; &nbsp;</em></p> <p>鈥淭his technology could even be applied for use in remote Antarctic research bases or for something as fanciful as space travel,鈥 Pardee said. 鈥淚f deployed in combination with a DNA synthesizer, the gene sequences that encode the manufacturing instructions could be electronically transmitted to remote end users, converted to DNA, and used to guide the cell-free manufacturing platform to produce therapeutics to meet unanticipated needs.鈥</p> </div> <div class="field field--name-field-news-home-page-banner field--type-boolean field--label-above"> <div class="field__label">News home page banner</div> <div class="field__item">Off</div> </div> Thu, 22 Sep 2016 17:08:44 +0000 ullahnor 101088 at
