INTRO' EXCERPT
Some of the same mutations allowing humans to fend off deadly infections also make us more prone to certain inflammatory and autoimmune diseases, such as Crohn's disease. In a Review published November 27 in the journal Trends in Immunology, researchers describe how ancestral origins impact the likelihood that people of African or Eurasian descent might develop immune-related diseases. The authors also share evidence that the human immune system is still evolving depending on a person's location or lifestyle.
"In the past, people's lifespans were much shorter, so some of these inflammatory and autoimmune diseases that can appear in the second half of life were not so relevant," says first author Jorge Dominguez-Andres, a postdoctoral researcher at Radboud Institute for Molecular Life Science in the Netherlands. "Now that we live so much longer, we can see the consequences of infections that happened to our ancestors."
One of the body's best defenses against infectious diseases is inflammation...
