Malaria remains one of the world’s most devastating infectious diseases, claiming more than half a million lives each year. In Africa, the illness is mostly caused by a parasite carried by mosquitoes – Plasmodium falciparum.
When the parasite invades the human body, it faces a hostile environment: soaring fevers, attacks from the body’s immune system, and the stress of antimalarial medicines. Yet it can survive, thanks to an internal defence system made up of “helper” molecules known as heat shock proteins.
Among these, a powerful group called small heat shock proteins act as the parasite’s last line of defence. These molecules behave like tiny bodyguards, protecting other proteins inside the parasite from damage when conditions become extreme. They are the parasite’s emergency rescue team when energy reserves are dangerously low, such as during high fever or exposure to drugs.
