For the first time ever, a molecule able to prevent the invasion of blood cells by parasites of the genus Plasmodium, responsible for malaria, has been identified and described by CNRS scientists,1 in collaboration with American and English colleagues. Their findings, which have just been published in Nature Communications, confirm the key role that myosin A—the ‘molecular motor’ of Plasmodium—plays in their infiltration of human hosts and penetration of their red blood cells, which triggers malarial attacks. Myosin A is found in all forms adopted by Plasmodium during the course of an infection, which makes it a convenient target for an inhibitor.
