TLDR
An overview of recent developments within the pyroptosis field is presented, beginning with the discovery of Gasdermin D (GSDMD) as a substrate of caspase-1 and caspases-11 upon detection of cytosolic lipopolysaccharide (LPS).

Caspase-1-induced pyroptosis is an innate immune effector mechanism against intracellular bacteria (111.33)

TL;DR: It is demonstrated that activation of caspase-1 clears intracellular bacteria in vivo independently of IL-1β and IL-18 and establishes pyroptosis as an efficient mechanism of bacterial clearance by the innate immune system.

The gasdermins, a protein family executing cell death and inflammation

TL;DR: This Review provides a comprehensive overview of the gasdermin family, the mechanisms that control their activation and their role in inflammatory disorders and cancer.
Journal ArticleDOI

Guidelines for the use of flow cytometry and cell sorting in immunological studies (second edition)

Andrea Cossarizza, +462 more
TL;DR: These guidelines are a consensus work of a considerable number of members of the immunology and flow cytometry community providing the theory and key practical aspects offlow cytometry enabling immunologists to avoid the common errors that often undermine immunological data.
Journal ArticleDOI

Pyroptosis: mechanisms and diseases.

TL;DR: It is described that pyroptosis is a double-edged sword for tumors and the rational use of this dual effect will help to further explore the formation and development of tumors, and provide ideas for patients to develop new drugs based on pyroPTosis.

The inflammasome: a molecular platform triggering activation of inflammatory caspases and processing of proIL-beta.

TL;DR: In this article, the inflammasome is identified as a caspase-activating complex that comprises caspases-1, casp-5, Pycard/Asc, and NALP1, a Pyrin domain-containing protein sharing structural homology with NODs.

Lipid Rafts As a Membrane-Organizing Principle

TL;DR: The evidence for how this principle combines the potential for sphingolipid-cholesterol self-assembly with protein specificity to selectively focus membrane bioactivity is reviewed.
Journal ArticleDOI

Cleavage of GSDMD by inflammatory caspases determines pyroptotic cell death

TL;DR: Gasdermin D (Gsdmd) is identified by genome-wide clustered regularly interspaced palindromic repeat-Cas9 nuclease screens of caspase-11- and caspasing-1-mediated pyroptosis in mouse bone marrow macrophages to offer insight into inflammasome-mediated immunity/diseases and change the understanding of pyroPTosis and programmed necrosis.
Journal ArticleDOI

Sorting of GPI-anchored proteins to glycolipid-enriched membrane subdomains during transport to the apical cell surface

TL;DR: It is shown that a protein with a glycosylphosphatidyl inositol (GPI) anchor can be recovered from lysates of epithelial cells in a low density, detergent-insoluble form, supporting the model proposed by Simons and colleagues for sorting of certain membrane proteins to the apical surface after intracellular association with glycosphingolipids.
Journal ArticleDOI

Activation and regulation of the inflammasomes

TL;DR: The complex regulatory mechanisms that facilitate a balanced but effective inflammasome-mediated immune response are discussed, and the similarities to another molecular signalling platform — the apoptosome — that monitors cellular health are highlighted.
