While we still do not know just how Alzheimer’s progresses or what role the fibrils play, they are always found in Alzheimer’s-ridden brains and are considered diagnostic markers of the disease. Marked by the red glow, A-beta peptide may give birth to Alzheimer’s disease through <A href="http://discovermagazine.com/2007/jul/can-we-prevent-alzheimer2019s-disease" class="external-link">mechanisms still unknown</A>. “It could be that the fibrils are toxic outside the cells, killing the neurons,” says <A target="_blank" href="http://www.bio.brandeis.edu/faculty/grigorieff.html" class="external-link">Nikolaus Grigorieff</A>, head of the Brandeis team that created the image. Alternatively, he says, small clumps of the peptide itself could be to blame. “With this 3-D image, we can see what path the peptide takes,” he says, helping us understand the properties of the fibril and get closer to curing this disease.</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/F0DF20C6-EE11-482E-A2C6-CC9357F888EC/blog/" title="blog or email this clip"><img src="http://content9.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>
