Linking infections with autoimmune disease + modified virus discover new autoantibodies

Article here* noticed that they use engineered virus to look for autoantibodies - similar to the approach of the group at Yale [Aaron Ring etc. using genetically modified fungi to produce target protein].
From the press article -
"They took a technique in which viruses are engineered to display bits of proteins like flags on their surface, called phage display immunoprecipitation sequencing (PhIP-Seq), and further optimized it to screen human blood for autoantibodies."
