What type of therapy in immunotherapy aims to suppress an immune response?

The correct answer is suppression therapy because this type of immunotherapy specifically focuses on dampening or inhibiting the immune response. Suppression therapy is commonly used in scenarios where overactive immune responses can lead to conditions such as autoimmune diseases, where the immune system mistakenly attacks the body’s own tissues.

In this context, the objective is to reduce inflammation and the overall activity of the immune system, preventing it from causing harm. This is achieved through a variety of methods, which may include the use of medications that target specific pathways or cells involved in immune activation.

While activation therapy would involve boosting the immune response for treatments, such as fighting cancer, and preventive therapy could relate to preventing infections or diseases by enhancing defenses, these do not align with the goal of suppressing the immune response. Thus, suppression therapy stands out distinctly as the correct choice for therapies aimed specifically at reducing immune system activity.
