Human immune response modulation

Human immune response modulation refers to the therapeutic intervention aimed at altering the immune system's activity, either by enhancing or suppressing its components. It is not a single molecular target but a complex biological process involving a network of cells, signaling molecules, and receptors (National Cancer Institute, 2024). In the context of autoimmune diseases and organ transplantation, modulation typically involves immunosuppression to prevent tissue damage or rejection. Conversely, in oncology and infectious diseases, immunostimulation is employed to bolster the body's natural defenses against pathogens or tumor cells (StatPearls, 2023). Because this term describes a broad physiological outcome, it is considered a therapeutic category rather than a discrete protein or enzyme target. Drugs classified as immunomodulators achieve their effects by interacting with specific targets such as cytokines, checkpoint receptors, or intracellular signaling kinases (Nature Reviews Drug Discovery, 2020).

The mechanism of action varies significantly depending on the specific molecular target involved, but generally entails the modulation of signaling pathways to either suppress or stimulate immune cell activity, cytokine release, and antibody production (StatPearls, 2023).
