Common origin behind major childhood allergies discovered

Several major childhood allergies may all stem from the community of bacteria living in our gut, according to a new study led by researchers at the University of British Columbia and BC Children’s Hospital. The research, published in Nature Communications, identifies gut microbiome features and early life influences that are associated with children developing any of four common allergies — eczema, asthma, food allergy, and/or hay fever. The findings could lead to methods of predicting whether a child will develop allergies and ways to prevent them from developing at all.

For the study, researchers examined clinical assessments from 1,115 children who were tracked from birth to age five. The researchers evaluated the children’s microbiomes from stool samples collected at clinical visits at three months and one year of age.

Artificial kidney may free patients from dialysis

Scientists at UC San Francisco are working on a new approach to treating kidney failure that could one day free people from needing dialysis or having to take harsh drugs to suppress their immune system after a transplant. They have shown for the first time that kidney cells, housed in an implantable device called a bioreactor, can survive inside the body of a pig and mimic several important kidney functions. The device can work quietly in the background, like a pacemaker, and does not trigger the recipient’s immune system to go on the attack.
