6.3.2.43 | medicine | in the presence of antimicrobial peptides produced by epithelial cells and macrophages, lysX expression increases significantly. Strains with higher lysX expression show increased levels of intracellular survival in vivo and in vitro and induce more severe lesion related with pneumonia. The ability of Mycobacterium tuberculosis to replicate intracellularly is directly correlated to the level of lysX expression | Mycobacterium tuberculosis |

2.3.2.3 | Mycobacterium tuberculosis | in the presence of AMPs, lysX expression increases significantly. Strains with higher lysX expression show increased levels of intracellular survival in vivo and in vitro and induce more severe lesion related with pneumonia. Comparisons of lysX absolute expression in different strains of Mycobacterium tuberculosis with and without LL-37 (strains H37Rv, H37Ra, Beijing, Beijing4P, MDR, and 5186). Strains H37Rv and Beijing strains similar results are obtained after 30 and 60 min of incubation. H37Ra and Beijing strains do not show differences among stimulation times whereas Beijing, Beijing4P, MDR and 5186 strains showed statistic differences among stimulation times when compared with the respective NoTx condition | up |

2.3.2.3 | physiological function | Mycobacterium tuberculosis (Mtb) has developed mechanisms to avoid antimicrobial peptides (AMPs) activity, for instance lysX adds lysine residues to surface phospholipids changing their net charge, leading to the repelling of the AMPs. In the presence of AMPs, lysX expression increases significantly. Strains with higher lysX expression show increased levels of intracellular survival in vivo and in vitro and induce more severe lesion related with pneumonia. Ability of Mtb to replicate intracellularly is directly correlated to the level of lysX expression showing that the amount of lysX produced by the bacterial cell is an important variable for the modulation of Mtb virulence.
