Pyroptosis is a form of programmed cell death that occurs in response to infection or inflammation. It is characterized by the activation of specific proteins called caspases, which lead to cell swelling, membrane rupture, and the release of inflammatory substances. This process helps to eliminate infected cells and alert the immune system to the presence of pathogens. Unlike other forms of cell death, such as apoptosis, pyroptosis is associated with a strong inflammatory response. The release of pro-inflammatory cytokines can recruit immune cells to the site of infection, enhancing the body's defense mechanisms. This makes pyroptosis an important aspect of the immune response.
