Abstract:
Caspases are crucial regulators of programmed cell death, mediating pathways such as apoptosis, pyroptosis, necroptosis and ferroptosis. Their activity is intricately controlled by epigenetic modifications, molecular interactions and post-translational changes, reflecting their central role in cellular homeostasis and disease mechanisms. Dysregulated caspase functions are linked to a wide array of conditions, including cancer, neurodegenerative disorders and inflammatory diseases, establishing their importance as potential therapeutic targets. The roles and regulation of caspases across subcellular compartments and their molecular interactions provide critical insights into the complexity of programmed cell death. Here, this review synthesizes current knowledge on the diverse functions of caspases, offering a comprehensive foundation for exploring innovative therapeutic strategies.

Overview of Cell Death
Cell death was observed in the early 19th century, but there was no experimental evidence to prove it. In 1842, Carl Vogt first discovered cell death in a metamorphic toad; however, it was not termed ‘cell death.’ Scientists discovered different cell death pathways only in the...
