Macrophages are specialised immune cells that destroy bacteria and other harmful organisms. KU Leuven scientists, Belgium, have come to the surprising conclusion that some macrophages in the intestines of mice can survive for quite some time. Most importantly, these long-lived macrophages are vital for the survival of the nerve cells of the gastrointestinal tract. This sheds new light on neurodegenerative ...

Because bacteria are routinely genetically engineered in science labs, there is great excitement about the possibility of tweaking the genes of our intestinal interlopers so that they ...
