This study investigates how cells use Tapasin proteins to present markers on their surface, allowing immune cells to recognize and target infection or disease. The authors found that two forms of Tapasin help cells to present these markers, while one form of Tapasin inhibits this process. The researchers propose that a balance between these two activities provides fine control over the immune system, enabling it to combat pathogenic cells without damaging healthy tissue.
