Abstract

The supra-molecular structure of LPS aggregates governs outer membrane permeability and activation of the host immune response during Gram-negative bacterial infections. Molecular dynamics simulations unveil at atomic resolution the subtle balance between cation hydration and cross-linking ability in modulating phase transitions of LPS membranes.
