Researchers typically do this using a virus to carry the genetic cargo into cells, because that’s what <A href="http://www.sciam.com/article.cfm?id=experts-where-did-viruses-come-fr">viruses evolved to do</A> with their own genetic material.</P></blockquote><div style="height: 2px; font-size: 2px; background: #dcdcdc; border-bottom: solid 1px #f5f5f5; margin: 2px 4px;"></div><blockquote style="text-align: left; padding: 0px 8px; margin: 4px 0px 8px 0px; background: transparent; border: none;" cite="http://www.sciam.com/article.cfm?id=experts-gene-therapy&sc=rss"><DIV>The treatment, which was first tested in humans in 1990, can be performed inside or outside of the body. When it’s done inside the body, doctors may inject the virus carrying the gene in question directly into the part of the body that has defective cells. This is useful when only certain populations of cells need to be “fixed.” For example, researchers are using it to try to treat Parkinson's disease, because only part of the brain must be targeted. This approach is also being used to treat eye diseases and hemophilia, an inherited disease that leads to a high risk for excess bleeding, even from minor cuts.</DIV></blockquote></div><div style="margin: 0px 6px 6px 4px;"><table style="font-size: 11px;border-spacing: 0px;padding: 0px;" cellpadding="0" cellspacing="0" width="100%"><tr><td style="background:transparent;border-width:0px;padding:0px;">&nbsp;</td><td align="right" style="background:transparent;border-width:0px;padding:0px;width:107px" width="107"><a href="http://clipmarks.com/share/E4C98573-F0BC-40FE-925A-4E6D2D62630F/blog/" title="blog or email this clip"><img src="http://content8.clipmarks.com/images/c2b-foot.png" border="0" alt="blog it" width="107" height="17" style="border-width:0px;padding:0px;margin:0px;" /></a></td></tr></table></div></div>
