The human body loses several billions of cells daily. When cells die in vivo, the
corpse of each dead cell is immediately cleared. Specifically, dead cells are
efficiently recognized and cleared by multiple types of neighboring phagocytes.
Early research on cell death focused more on molecular mechanisms of cell death
regulation while the cellular corpses were merely considered cellular debris.
However, it has come to light that various biological stimuli following cell
death are important for immune regulation. Clearance of normal dead cells occurs
silently in immune tolerance. Exogenous or mutated antigens of malignant or
infected cells can initiate adaptive immunity, thereby inducing immunogenicity by
adjuvant signals. Several pathogens and cancer cells have strategies to limit the
adjuvant signals and escape immune surveillance. In this review, we present an
overview of the mechanisms of dead cell clearance and its immune regulations.
