A Protein from Primate may Save Humans from HIV !

Protein can efficiently stop HIV virus from entering and infecting blood cells, according to researchers of the University of Central Florida. // Advancement has made man to stop producing this protein that was produced by our predecessors.

HIV-1 has a technique to escape the antiviral drugs targeted against it. It does so by frequently getting mutated. But a research team led by Associate Professor Alexander Cole of UCF's Burnett College of Biomedical Sciences has demonstrated that over 100 days the virus develops only weak resistance to retrocyclin, a defense peptide still found in monkeys and lower primates.

If additional laboratory tests demonstrate only weak resistance, Cole will study how retrocyclin could be developed into a drug designed to prevent the HIV virus from entering human cells.

Cole is also working with Henry Daniell, a UCF professor of molecular biology and microbiology, to develop a way to grow retrocyclin through genetically engineered tobacco plants. The retrocyclin gene would be incorporated into the chloroplast genome of tobacco cells before the plants grow. Daniell has developed a similar approach to growing anthrax vaccine in tobacco plants.

An inexpensive way to produce the drug with only a small amount of tobacco would help to make it accessible in areas such as Southeast Asia, Africa and the Caribbean where the disease spreads most quickly.

"If we could develop retrocyclin in plants and produce enough of the drug cheaply, we could potentially save a lot of lives," Cole said.

Cole was recently awarded about $4 million of National Institutes of Health grants through 2011 for the HIV-1 research and similar studies. The grants were provided through the National Institute of Allergy and Infectious Diseases; National Institute of Child Health and Human Development; and the National Heart, Lung and Blood Institute.

Cole started his research into theta-defensins at the Univer
