Caspases are a family of enzymes that play a crucial role in the process of programmed cell death, also known as apoptosis. They are produced as inactive precursors and become activated in response to various cellular signals. Once activated, caspases cleave specific proteins within the cell, leading to a series of events that ultimately result in cell death. In addition to their role in apoptosis, caspases are also involved in inflammation and immune responses. They help regulate the activation of inflammatory cytokines, which are important for the body's defense against infections. Dysregulation of caspases can contribute to various diseases, including cancer and neurodegenerative disorders.
