<p>   u00a0</p>  <div id="cke_pastebin">   Sonia Arora, an assistant professor at Kean University in New Jersey, is delving into understanding the curative properties of the neem tree in fighting the virus that causes AIDS.</div>  <div id="cke_pastebin">   u00a0</div>  <div id="cke_pastebin">   Her preliminary results seem to indicate that there are compounds in neem extracts that target a protein essential for HIV to replicate. If further studies support her findings, Arora&rsquo;s work may give clinicians and drug developers a new HIV-AIDS therapy to pursue.</div>  <div id="cke_pastebin">   u00a0</div>  <div id="cke_pastebin">   Extracts from neem leaves, bark and flowers are used throughout the Indian subcontinent to fight against pathogenic bacteria and fungi.</div>  <div id="cke_pastebin">   u00a0</div>  <div id="cke_pastebin">   &ldquo;The farther you go into the villages of India, the more uses of neem you see,&rdquo; said Arora.</div>  <div id="cke_pastebin">   u00a0</div>  <div id="cke_pastebin">   Tree branches are used instead of toothpaste and toothbrushes to keep teeth and gums healthy, and neem extracts are used to control the spread of malaria.</div>  <div id="cke_pastebin">   u00a0</div>  <div id="cke_pastebin">   Practitioners of Ayurvedic medicine, a form of traditional Indian alternative medicine, even prescribe neem extracts, in combination with other herbs, to treat cardiovascular diseases and control diabetes. The neem tree, whose species name is Azadirachta indica and which belongs to the mahogany family, also grows in east Africa.</div>  <div id="cke_pastebin">   u00a0</div>  <div id="cke_pastebin">   Arora&rsquo;s scientific training gave her expertise in the cellular biology of cancer, pharmacology, bioinformatics and structural biology.</div>  <div id="cke_pastebin">   u00a0</div>  <div id="cke_pastebin">   When she established her laboratory with a new research direction at Kean University in 2008, Arora decided to combine her knowledge with her long-time fascination with natural products. The neem tree beckoned.</div>  <div id="cke_pastebin">   u00a0</div>  <div id="cke_pastebin">   Arora dived into the scientific literature to see what was known about neem extracts. During the course of her reading, Arora stumbled across two reports that showed that when HIV-AIDS patients in Nigeria and India were given neem extracts, the amount of HIV particles in their blood dropped.</div>  <div id="cke_pastebin">   u00a0</div>  <div id="cke_pastebin">   Intrigued, Arora decided to see if she could figure out what was in the neem extract that seemed to fight off the virus.</div>  <div id="cke_pastebin">   u00a0</div>  <div id="cke_pastebin">   She turned to bioinformatics and structural biology to see what insights could be gleaned from making computer models of HIV proteins with compounds known to be in neem extracts.</div>  <div id="cke_pastebin">   u00a0</div>  <div id="cke_pastebin">   From the literature, she and her students found 20 compounds present in various types of neem extracts. When they modelled these compounds against the proteins critical for the HIV life-cycle, Arora and her team discovered that most of the neem compounds attacked the HIV protease, a protein essential for making new copies of the virus.</div>  <div id="cke_pastebin">   u00a0</div>  <div id="cke_pastebin">   Arora&rsquo;s group is now working on test-tube experiments to see if the computer models hold up with actual samples.</div>  <div id="cke_pastebin">   u00a0</div>  <div id="cke_pastebin">   If her work bears out, Arora is hopeful that the neem tree will give a cheaper and more accessible way to fight the HIV-AIDS epidemic in developing countries, where current therapies are priced at levels out of reach of many people.</div>  

An Indian origin researcher has hinted that extracts from neem tree, profuse in tropical and subtropical areas, may thwart the virus from multiplying.
