Malaria's newest pathway into human cells identified
Date:9/24/2010

uses this protein to correctly identify the red blood cell and say 'Yes, this is the one we want to invade', it's like a quality assurance process," Professor Cowman said.

"The PfRh4-CR1 pathway is one of the most important of the pathways we've identified for entry of malaria parasites into cells," Professor Cowman said. "We are now at the stage where we have identified the best combination of proteins for a vaccine, and are ready to start clinical development.

"When both glycophorin and CR1 pathways are blocked, there is a 90 per cent decrease in infection of the cells with the parasite. These results suggest that if a vaccine were to stimulate the immune system to recognise and generate antibodies to the prevalent invasion pathways, there is a good chance it would lead to a significant decrease in malaria infection."
