The immunoproteasome plays a pivotal role in the immune system by helping cells recognize and respond to pathogens. This cellular enzyme complex dismantles proteins from invading bacteria and viruses, presenting fragments to immune cells to initiate a defense response. However, in the context of autoimmune diseases, the immunoproteasome can become dysregulated and behave inappropriately, mistakenly
