Lipid signals help cells seal damage from bacterial attacks
Epithelial cells act as the body's frontline barriers, protecting against microbes, toxins, and other harmful substances. However, these cells face constant threats from bacterial infections, including pore-forming toxins that perforate the plasma membrane. Recent scientific discoveries reveal that lipid signals play a crucial role in helping cells quickly detect and seal this membrane damage. Understanding these repair mechanisms opens new pathways for developing treatments against bacterial attacks.
