Abstract:
Immune checkpoint inhibitors (ICIs) have revolutionized cancer treatment, significantly improving outcomes for various malignancies. Despite their clinical success, only a subset of patients benefits from ICIs treatment, underscoring the need for innovative strategies to enhance their therapeutic potential. Ferroptosis, a unique form of programmed cell death driven by iron-dependent lipid peroxidation, has emerged as a promising partner for enhanced immunotherapy. Combining ferroptosis inducers with immune checkpoint blockade has shown promising potential in improving the efficacy of cancer immunotherapy. This study explores the mechanisms of ferroptosis and immune checkpoint inhibitors for synergistic cancer treatment, and reviews recent delivery platforms integrating ferroptosis and immune checkpoint blockade for enhanced therapy.

Cancer Therapies
However, cancer treatments can pose several challenges, as therapies used to kill cancer cells are generally also toxic to normal cells. Moreover, cancer cells mutate rapidly and can develop resistance to chemical agents or radiation therapy. Besides, all types of cancer cells may not respond to the same therapy. Some cancer cells respond to one...
