汤头条 researcher receives major congressional grant for malaria parasite study
Contact: Sasha Steinberg
STARKVILLE, Miss.鈥 A grant from the world鈥檚 foremost medical research organization is assisting a Mississippi State faculty member with her innovative work on the specific properties of malaria parasites.
Diana C. Outlaw, who has served as an assistant professor of biology since 2009, is using the $81,712 congressional award from the National Institutes of Health鈥檚 Institute of Allergy and Infectious Diseases to gain a deeper understanding of malaria parasite emergence in new host species, such as humans and wildlife.
鈥淭his study is innovative because it represents the first taxonomically comprehensive inventory of genes that may explain how malaria parasites adapt to novel hosts, and it is particularly timely because many recent studies have shown host shifts between humans and apes and between birds and bats,鈥 explained Outlaw.
As an evolutionary biologist, Outlaw specializes in phylogenetic systematics. In other words, she said, she seeks to better understand how groups of organisms are related to each other through their evolutionary history.
鈥淪usan Perkins at the Museum of Natural History in New York is a collaborator on this project, and she actually published the first big phylogenetic tree of malaria parasites back in 2002 as part of her dissertation work, so she really pioneered this field,鈥 Outlaw said.
As part of the project, more than 40,000 mosquitoes from across the state of Mississippi have been collected, explained Outlaw, a general biology master鈥檚 graduate of Sonoma State University in Rohnert Park, California.
Because mosquitoes are vectors for diseases other than malaria, Outlaw said sharing her lab鈥檚 samples and data with other experts at Mississippi State and in the local community can contribute to additional discoveries.
鈥淢y graduate student David Larson extracted DNA from nearly all of those samples for our purposes, and we鈥檙e also making those samples available to other labs, such as those at the College of Veterinary Medicine that want to look at West Nile Virus,鈥 she said.
鈥淚t makes it that much easier to expand the types of questions that we can answer when you have a community of colleagues like I have here at Mississippi State,鈥 added Outlaw, also a general biology doctoral graduate of the University of Memphis.
Outlaw expressed particular appreciation for the assistance of Extension professor Jerome Goddard, Extension professor in the Department of Biochemistry, Molecular Biology, Entomology and Plant Pathology; and Andrea Varela-Stokes, associate professor in the College of Veterinary Medicine鈥檚 basic sciences department.
According to Outlaw, the age of the malaria parasite lineage at the extant鈥攐r the ones that are around today鈥攊s roughly 20 million years old. As geographic areas are explored, more malaria parasites lineages or species can be found, she said.
鈥淚n adding all of these new species, we鈥檙e growing this phenomenal tree of life of these parasites鈥攖housands and thousands and thousands of species rich鈥攁nd that can more broadly inform us of how life evolves,鈥 Outlaw said. 鈥淭here鈥檚 so much more diversity in life on Earth than we even realize, and the deeper we look, the more we find. That鈥檚 what makes science great.鈥
Rick Travis, interim dean of 汤头条鈥檚 College of Arts and Sciences, said Outlaw鈥檚 accomplishment is one that 鈥渟peaks to the caliber of the quality of our faculty in biological sciences.鈥
鈥淭his is a very competitive program, and we are excited that Dr. Outlaw has received this award,鈥 Travis said.
