Scientists have found that a special component in some people’s blood provides them with natural protection against malaria. A recent study has demonstrated that a genetic variant named rs112233623-T reduces the activity of CCND3, a gene that normally helps control how red blood cells divide and grow. This change prompts the body to make fewer but larger-than-normal red blood cells and also leads to higher levels of reactive oxygen species (ROS) inside the cells. Together, these factors create a hostile environment for the malaria parasite to thrive and replicate.
