The standard test so far has been the swab test, in which a swab goes up your nose and to the back of your throat. But an alternative method of specimen collection, using […]

Genomics, transcriptomics and proteomics shed light on autoimmune thyroid disease

Scientists at deCODE genetics, a subsidiary of Amgen, and their collaborators from the Icelandic healthcare system, University of Iceland and the Karolinska Institute in Sweden, have published a study in Nature comparing over 30,000 patients with autoimmune thyroid disease from Iceland and U.K. with 725,000 controls. Autoimmune thyroid disease (AITD) is the most common autoimmune disease and is highly heritable. […]

Study shows nervous and immune systems ‘need to talk’ for bone repair

This, they showed, partly relies on a protein known as nerve growth factor (NGF). Now, the researchers have dug deeper into this process to better […]
