Sea cucumber helps in the fight against malaria

According to research by an international team of scientists with the sea cucumber is possible antidote that offer block the transmission of malaria parasites. Cucumber produces a protein lectin that prevents the development of these parasites. International Genetic Engineering Group took the mosquitoes that are carriers of the malaria parasite to get the same protein in the intestine. Study of malaria parasites showed that the protein prevents the development of parasites in insects. Malaria affects 500 million people worldwide and kills more than one million people every year. About 40% of the world population at risk. To stimulate the production of lectin mosquitoes, the researchers, the pieces of the sea cucumber gene, a protein, a gene producing insects. The results showed that the method for some parasites, which were the cause of malaria was rezultativen. Lectin is poisonous to the parasites that are in the early stages of development, so-called ookinete. Ookinety normally migrate through the stomach wall and produce thousands of mosquitoes like zygotes invade the salivary glands, and infect a person after bitten by a mosquito. But the defeat ookinete lectin, they die earlier than they begin the process of death. According to Professor Bob Sinden (Bob Sinden), sea cucumber protein significantly reduced the number of parasites in mosquitoes, but not completely removed them from all insects. In the current phase of the development of genetically modified mosquitoes were dangerous to humans. The first goal of genetic engineering is to stop a way to the development of malaria parasites in insects. Made the first and most important step in the ability to control this infection, the experts in the field of malaria Professor Sanjeev Krishna (Sanjeev Krishna).
