A recent study by the Centers for Disease Control and Prevention found that bacterial diseases remain a leading cause of death worldwide, with five strains accounting for nearly 55 percent of all bacterial infection deaths.

Treatments for those diseases, however, remain extremely underfunded and under-resourced globally.

Seeking a potential cure, 黑料网 Professor of Biochemistry Thomas Leeper has earned a two-year, $200,000 grant through KSU鈥檚 Office of Research Grand Challenges initiative to study and produce antibacterial treatments that target drug-resistant bacteria like Staphylococcus aureus, more commonly known as MRSA. In addition to treating bacterial infections, Leeper hopes to raise awareness of those ailments.

鈥淲e've done a really good job in general with treating most cancers, but we have dropped the ball when it comes to treating microbial disease,鈥� he said. 鈥淏acterial disease and viral infections should scare the heck out of people, and we hope to fix that.鈥�

"The project seeks to use proteins to fight harmful bacteria. Some types of drug-resistant bacteria can enter and infect eukaryotic cells, allowing those pathogens to evade common antibiotics. Leeper is attempting to hijack the natural systems that host cells use to bring in nutrients to target these intracellular pathogens with novel antimicrobial proteins."

鈥淲e're always looking for new antibiotics, but resistance is outpacing it,鈥� he said. 鈥淢y lab has been able to anticipate this problem by looking at strategies that would overcome the resistance-developing mechanisms.鈥�

The project will involve student researchers, and Leeper said the grant money will go toward building a team of seven undergraduates as well as a post-doctoral researcher.

Leeper is also nearing the end of a five-year National Institutes of Health grant investigating drugs to treat cystic fibrosis. He said the internal grant, in terms of personnel and equipment, will boost the laboratory鈥檚 capacity to advance this overall study of effective medicinal treatments.

Leeper鈥檚 co-investigators on the project are Jonathan McMurry and Anton Bryantsev. McMurry, a professor of chemistry in KSU鈥檚 College of Science and Mathematics, has a process in his laboratory that allows experimental delivery of proteins into bacteria. Bryantsev, an associate professor of developmental biology, works with fruit flies, which are model organisms for bacterial infections and can provide insights into the effectiveness of these proteins.
