Immunogenic cell death is any type of cell death eliciting an immune response. Both accidental cell death and regulated cell death can result in immune response. Immunogenic cell death contrasts to forms of cell death (apoptosis, autophagy or others) that do not elicit any response or even mediate immune tolerance.
The name 'immunogenic cell death' is also used for one specific type of regulated cell death that initiates an immune response after stress to endoplasmic reticulum.
