  1. 01LabIn vitro (cells)Activity measurement

    In Neisseria meningitidis, mutations within the mtrD gene increased susceptibility to human LL‑37.

    In plain wordsIn lab tests, meningococcal bacteria with a changed mtrD gene were more easily killed by LL‑37.

    Summary
    Mutations within the mtrD or lptA genes also increased meningococcal susceptibility to two structurally unrelated CAMPs, human LL-37 and protegrin-1.

    Summary · context
    To ascertain the mechanisms by which meningococci resist PxB, mutants that displayed increased sensitivity (> or =4-fold) to PxB were identified from a library of mariner transposon mutants generated in a meningococcal strain, NMB.
