Intestinal cells protect us from harmful bacteria by forming a physical barrier and raising immune danger signals when needed. This research reveals a nuclear “knight” molecule that suppresses unnecessary immune activation during metabolic stress, helping maintain intestinal health and preventing excessive inflammation.

Antibiotic-resistant bacteria like Salmonella cause millions of deaths worldwide. This research explores prohibitin 1, a mitochondrial protein, as an alternative defense. Mouse studies show that higher prohibitin 1 levels protect against bacterial infections, offering a potential non-antibiotic treatment to combat infections and reduce antibiotic resistance.
