Pyroptosis

The official blog of Cell Signaling Technology CST where we discuss what to expect from your time at the bench, share tips, tricks, pyroptosis, and information. Under the category of necrotic cell death, pyroptosis, there are many pyroptosis, as well as some newly described, processes of cellular destruction. Contrary to classical thinking, necrotic cell death is not always physical and accidental in nature.

Currently, pyroptosis has received more and more attention because of its association with innate immunity and disease. The research scope of pyroptosis has expanded with the discovery of the gasdermin family. A great deal of evidence shows that pyroptosis can affect the development of tumors.

Metrics details. A Correction to this article was published on 22 September A Correction to this article was published on 01 July Unraveling the mystery of cell death is one of the most fundamental progresses of life sciences during the past decades. Regulated cell death RCD or programmed cell death PCD is not only essential in embryonic development, but also plays an important role in the occurrence and progression of diseases, especially cancers. Escaping of cell death is one of hallmarks of cancer. Gasdermin family proteins are the executors of pyroptosis. Pyroptosis exerts tumor suppression function and evokes anti-tumor immune responses. Therapeutic regimens, including chemotherapy, radiotherapy, targeted therapy and immune therapy, induce pyroptosis in cancer, which potentiate local and systemic anti-tumor immunity. On the other hand, pyroptosis of normal cells attributes to side effects of anti-cancer therapies. In this review, we focus on the regulatory mechanisms of pyroptosis and the tumor suppressive function of pyroptosis.

As a non-lytic form of cell death, pyroptosis, apoptosis is generally immunogenically silent. This result may have a certain reference value in the pyroptosis of obese cancer patients.

Cell death is crucial for organogenesis in utero and successful control of host cell populations in healthy tissues, but can also play a part in disease that occurs in response to toxic insults or microbial infection.

Pyroptosis is a highly inflammatory form of lytic programmed cell death that occurs most frequently upon infection with intracellular pathogens and is likely to form part of the antimicrobial response. This process promotes the rapid clearance of various bacterial, viral, fungal and protozoan infections by removing intracellular replication niches and enhancing the host's defensive responses. Pyroptosis can take place in immune cells and is also reported to occur in keratinocytes and some epithelial cells. The process is initiated by formation of a large supramolecular complex termed the inflammasome also known as a pyroptosome upon intracellular danger signals. These molecules recruit more immune cells and further perpetuate the inflammatory cascade in the tissue. However, in pathogenic chronic diseases, the inflammatory response does not eradicate the primary stimulus. A chronic form of inflammation ensues that ultimately contributes to tissue damage. Pyroptosis is associated with diseases including autoinflammatory, metabolic , and cardiovascular diseases, as well as cancer and neurodegeneration.
