Credit: Robson Kriiger Loterio Researchers have discovered a previously unidentified protein with antioxidant properties produced by Coxiella burnetii, a Gram-negative intracellular bacterium. This breakthrough suggests potential new treatments for autoimmune diseases and cancer. Researchers at the University of São Paulo, in collaboration with Australian colleagues, have discovered a unique bacterial protein capable of keeping human cells healthy even when the cells have a heavy bacterial burden. This breakthrough holds the potential for developing new treatments...
