Study shows autoantibodies behind lifelong risk of viral infection

A new study, published in the Journal of Experimental Medicine, shows that about 2% of the population develop autoantibodies against type 1 interferons, mostly later in life. This makes individuals more susceptible to viral diseases like COVID-19. The study, conducted by UZH researchers together with a USZ team, is based on an analysis of a large collection of historical blood samples. Virus infections trigger the cells of the immune system to release type 1 interferons. These proteins act as early messengers that warn uninfected cells and tissues that a virus is spreading. This allows cells to prepare themselves so that Read More
