Researchers have genetically modified mice to produce an antibacterial protein survive ingesting Salmonella typhimurium.
The antibacterial protein occurs naturally in the human gut.
|Defensins in the human body have a key role in defending us against invaders.|
The research team's findings are published online in this week's issue of Nature.
The team finds support of the idea that antibiotic peptides (defensins) in the lining tissues of the human body have a key role in defending us against invaders.
Dr Charles Bevins's team stated, "Future therapies may include the expression of peptides in selected cells and tissues".
