Dr. James Dalton will serve as LSU Executive Vice President of the LSU System and Chancellor of the Flagship A&M Campus.
Today, the LSU Board of Supervisors named Wade Rousse, Ph.D., as president of LSU System and James Dalton, Ph.D., as executive vice president of the LSU System and chancellor of the A&M campus.
Mike sits in his doctor's office during a follow-up visit for a lingering bacterial infection that is threatening his health. As he sits on the examination table, his doctor discusses options with him. "This is a tricky infection. There's one more antibiotic we can try." "Why aren't there more drug options?" Mike asks, confused. "Bacteria adapt quickly to existing drugs, but LSU researchers are now exploring ways to kill bacteria by starving them of iron." Mike's doctor explains bacteria's need for iron as a Goldilocks and the Three Bears situation... too much iron is poisonous ("Ack, too much!" the bacteria says...), but too little can also harm the bacteria... “LSU researchers are studying how bacteria monitor and regulate their iron levels…" Mike's doctor explains. While Mike's immune cells are busy protecting the iron in his body from bacterial thieves, the microbes that are causing his infection have a back-up plan: iron in storage. They can sense when their iron levels are low thanks to a sensitive iron-sensing pathway. The pathway involves a protein called ferredoxin that is activated by a signaling iron-sulfur cluster. “I’m running low! This man’s immune cells are hogging all the iron!” the microbe says. "Go get your own!" the immune cell yells back. An active ferredoxin helps to release iron particles normally stored in a large round container protein called bacterioferritin. A drug that interferes with this release of stored iron could kill the bad bacteria in Mike's body, helping his immune cells win their fight. "LSU researchers are also studying how a new drug that locks iron in storage can kill biofilm bacteria," the doctor says. Mike imagines a sick bacterium with bloodshot eyes, sighing, "UGHHH! I don't feel good..." A new type of antibiotic could prevent ferredoxin and bacterioferritin from interacting, trapping iron inside its storage container and tricking bacteria into thinking they have no iron available. Research saves lives!
