Ferroptosis can be induced in various ways. These include Gpx4 deletion, S100A4 inhibition, and cancer nanovaccines. These methods improve the tumor microenvironment. They work well with immune checkpoint inhibitors. This is seen in liver cancer and melanoma models
Ferroptosis shows necrotic morphology. It is similar to necroptosis. Both can trigger immune responses. They are types of immunogenic cell death.
CD8+ T lymphocytes mediate ferroptosis. Their cell death is highly immunogenic. This enhances the caspase-3 dependent immune response.
Ferroptosis is a type of cell death. It depends on iron. It occurs due to redox imbalance. This leads to lipid peroxidation. Mitochondria become dysfunctional. The plasma membrane becomes permeable quickly.
The immunogenic potential of ferroptosis is debated. Early studies showed promising results. Mouse fibrosarcoma cells responded to ferroptosis inducers. They released Alarmins / Damage-associated molecular pattern (DAMPs) like ATP and HMGB1. These support dendritic cell maturation. They also protected hosts from cancer cell challenges.
Ferroptosis occurs without caspase 3 and Caspase-7 activation. These caspases usually suppress the immune response.
