University of Queensland researchers have unlocked a way of fighting Listeria infections, which can cause severe illness in pregnant women and people with compromised immune systems.
During the study, researchers discovered a way to block Listeria from making the proteins that allow bacteria to survive and multiply in immune cells.
UQ Diamantina Institute’s Professor Antje Blumenthal said using a small, drug-like inhibitor has improved their understanding of the Achilles heel of Listeria.
“Listeria is found in the soil and sometimes in raw foods. Once ingested it can hide from the immune system and multiply inside immune cells,” Professor Blumenthal said.
“Instead of killing the bacteria, the immune cells are used by the bacteria to multiply and are often killed by Listeria growing inside them.
The study has been published in the journal PLOS Pathogens (DOI: 10.1371/journal.ppat.1010166).
This study, led by researchers at The UQ Diamantina Institute, included collaborations with Umeå University, Sweden; UQ School of Chemistry and Molecular Biosciences; Australian Infectious Diseases Research Centre; Institute for Molecular Bioscience; Mater Research Institute; Telethon Kids Institute, University of Western Australia; Monash University; University of Melbourne at the Peter Doherty Institute for Infection and Immunity and Hudson Institute of Medical Research.
