World Malaria Day -25th April
According to World Health Organisation statistics, Malarial parasite infected around 225 million and killed nearly 800,000 people worldwide in 2009. They seem to be developing resistance to the available drugs. In the recent studies it was found that the parasite is dependent on the kinases in the cells ( liver, RBCs) for their survival and multiplication. If these kinases are inhibited then it becomes a halt for parasite. Now there is a new hope that the newer Cancer drugs can kill malaria parasite Plasmodium, which is transmitted via the bites of infected mosquitoes. In the human body, the parasites reproduce in the liver, and then infect and multiply in red blood cells. Joint research by few organizations showed that, in order to proliferate, the malaria parasite depends upon a signalling pathway present in the host's liver cells and in red blood cells. They demonstrated that the parasite hijacks the kinases (enzymes) that are active in human cells, to serve its own purposes. When the research team used cancer chemotherapy drugs called kinase inhibitors to treat red blood cells infected with malaria , the parasite was stopped in its tracks.
