Immune system stimulation via antigen expression

Immune system stimulation via antigen expression refers to the process by which introduction or upregulation of antigens (substances recognized as foreign by the immune system) leads to the activation of innate and adaptive immune responses. This is a foundational principle underlying vaccination, where antigens are delivered to prime immune memory against pathogens, and in many cancer immunotherapies that seek to enhance immune recognition of tumor-associated antigens. The process hinges on the presentation of antigens by antigen-presenting cells (such as dendritic cells) via MHC molecules to T lymphocytes, leading to clonal expansion and activation of effector immune cells. This is not a discrete molecular target but a generalized strategy or pathway for therapeutic immune modulation.
