Scientists have identified a key protein common to malaria parasites opening the way to more effective vaccines or drugs against the life-threatening infections caused by the micro-organisms.The protein has sticky properties that enable it to bind to red blood cells among humans and other animals and form dangerous clumps that can block blood vessels. These clumps can cause severe illness including coma and brain damage. Scientists from the University of Edinburgh worked with researchers from Cameroon Mali Kenya and the Gambia to test their antibodies against the parasites collected from patients the journal Public Library of Science Pathogens reports.
