Summary

This study looked at how the immune system behaves in people with lupus (SLE) and mixed connective tissue disease (MCTD). Researchers measured immune cell responses and tracked disease activity over time. The goal was to better understand these long-term autoimmune diseases, which often affect young women, especially Black and Hispanic women. No treatment was given; this was an observation-only study to gather information for future therapies.
