EXP2 protein helps deadliest malaria parasite obtain nutrients during infection

Researchers from the National Institutes of Health and other institutions have deciphered the role of a key protein that the malaria parasite Plasmodium falciparum uses to obtain nutrients while infecting red blood cells. Their study appears in Nature Microbiology. According to the World Health Organization(link is external), in 2016 there were an estimated 216 million malaria cases and 445,000 malaria deaths. P. falciparum is responsible for most malaria-related deaths globally.

The parasite remodels the red blood cell it infects to obtain nutrients. During this process, the parasite secretes hundreds of proteins that need to be transported from the vacuole, the compartment in which the parasite resides, to the interior of the cell. A group of proteins, called the Plasmodium translocon of exported proteins (PTEX), has been shown to be essential for transporting materials to and from the vacuole. Previous studies have uncovered the function of one of the proteins in the PTEX group to reshape proteins for transport, but the function of other proteins in the group have not been well understood.

In the current study, researchers analyzing blood cell cultures from healthy people determined that the PTEX protein EXP2 forms a channel in the vacuole membrane, which allows for passage of proteins and cellular nutrients to supply the parasite. The researchers hope that their discovery will lead to the development of new drugs to prevent formation of the channel and block the transport of nutrients and proteins to the parasite.

The Southern Maryland Chronicle is a local, small business entrusted to provide factual, unbiased reporting to the Southern Maryland Community. While we look to local businesses for advertising, we hope to keep that cost as low as possible in order to attract even the smallest of local businesses and help them get out to the public. We must also be able to pay employees(part-time and full-time), along with equipment, and website related things. We never want to make the Chronicle a “pay-wall” style news site.

To that end, we are looking to the community to offer donations. Whether it’s a one-time donation or you set up a reoccurring monthly donation. It is all appreciated. All donations at this time will be going to furthering the Chronicle through hiring individuals that have the same goals of providing fair, and unbiased news to the community. For now, donations will be going to a business PayPal account I have set-up for the Southern Maryland Chronicle, KDC Designs. All business transactions currently occur within this PayPal account. If you have any questions regarding this you can email me at davidhiggins@southernmarylandchronicle.com

Thank you for all of your support and I hope to continue bringing Southern Maryland the best news possible for a very long time. — David M. Higgins II
