New research from the Francis Crick Institute has found how the malaria parasite protects itself from toxic compounds in red blood cells.<\/p>\n

\n <\/section>\n

Malaria causes around 400,000 deaths globally each year. It is caused by Plasmodium parasites which are transmitted by mosquitoes and grow in a person’s blood stream.<\/p>\n

In their study, published in Proceedings of the National Academy of Science<\/a>s<\/i>, Crick researchers together with colleagues from Germany and Switzerland identified a protein used by the malaria parasite to protect itself from a toxic compound in red blood cells. They hope this could lead to the development of drugs that block this process.
\nWhen the malaria parasite enters a red blood cell it digests haemoglobin, leading to the release of a compound called haem, which is toxic to the parasite if it is left loose inside the cell.
\nThe researchers found that to overcome this, the parasite uses a protein, called PV5, to control a process where free haem molecules are joined together into insoluble crystals which are not harmful. This is vital to the survival of the malaria parasite.
\nWhen the researchers blocked this protein in the lab, they found that the human-infecting malaria parasite made fewer and highly misshapen crystals. When the protein was blocked in mice that had been infected with a rodent strain of malaria, the parasite became more sensitive to several antimalarial drugs.
\nJoachim Matz, lead author and postdoctoral research fellow in the Malaria Biochemistry Laboratory at the Crick says: “The importance of haem crystallisation to malaria has been understood for a while, but what has been missing is knowledge about how this process is controlled by the parasite. By identifying a protein that is key to this process, we’ve opened the door to potential new treatments which can stop malaria in its tracks”.
\nMike Blackman, author and group leader of the Malaria Biochemistry Laboratory at the Crick says: “The issue of malaria developing resistance to antimalarial drugs is of grave concern. The parasite is already resistant to many drugs and this underpins the need to find new treatments.”
\n“We hope that an improved understanding of the mechanisms at play during this haem crystallisation process will provide valuable insights for the development of future drugs.”
\nThe researchers will continue to study the role of PV5 during haem crystallisation, with a view to identify the exact mechanism behind this process.<\/p>\n
