Scientists test 'Smart' immune protein in lab to calm autoimmune attacks

This was a small, completed lab study that tested whether specially engineered versions of a natural immune protein (called IL-2 muteins) could selectively boost a type of calming immune cell (regulatory T cells) taken from patients with various autoimmune and inflammatory diseases. The goal was to gather early evidence in a dish to see if these modified proteins work as intended on patient cells before considering future treatment trials. It involved blood samples from 67 adults with conditions like lupus, multiple sclerosis, rheumatoid arthritis, and others.
