Which class of medication is utilized to reduce immune response in autoimmune disorders?

The correct answer is tumor necrosis factor inhibitors, as this class of medication is specifically designed to target and reduce inflammation by inhibiting the activity of tumor necrosis factor (TNF), a cytokine involved in systemic inflammation. Autoimmune disorders often involve an overactive immune response that leads to tissue damage and chronic inflammation. By blocking TNF, these inhibitors can effectively decrease the immune system's attack on the body's own tissues, providing relief from symptoms in conditions such as rheumatoid arthritis and inflammatory bowel disease.

Other classes of medications listed do not primarily focus on modulating the immune response in the context of autoimmune disorders. Insulin derivatives are primarily used to manage blood sugar levels in diabetes. COX-2 inhibitors are used primarily for pain relief and inflammation but do not specifically target the immune response associated with autoimmune diseases. Alpha-glucosidase inhibitors are utilized to control blood glucose levels by delaying carbohydrate absorption, rather than addressing immune system activity.
