Pyroptosis: Caspase-11 Unlocks the Gates of Death [PDF]

Immunity, 2015
How inflammatory caspases trigger pyroptotic cell death is mostly unexplained. In this issue of Immunity, Núñez and colleagues report that caspase-11 cleaves the transmembrane channel pannexin-1, causing an efflux of cellular ATP that promotes a P2X7 receptor-dependent pyroptosis.

Regulation, Activation and Function of Caspase-11 during Health and Disease [PDF]

International Journal of Molecular Sciences, 2021
Caspase-11 is a pro-inflammatory enzyme that is stringently regulated during its expression and activation. As caspase-11 is not constitutively expressed in cells, it requires a priming step for its upregulation, which occurs following the stimulation of pathogen and cytokine receptors.

Caspase-3 western blot.

, 2022
Western blot of pro- and cleaved caspase-3 [ratio to ß-actin]. Shown are representative blots separated by location of lung tissue sampling (contusion site, ipsilateral control, and contralateral control). Lung tissue samples were homogenized, separated,

Regulation of caspase-3 processing by cIAP2 controls the switch between pro-inflammatory activation and cell death in microglia. [PDF]

, 2014
The activation of microglia, resident immune cells of the central nervous system, and inflammation-mediated neurotoxicity are typical features of neurodegenerative diseases, for example, Alzheimer's and Parkinson's diseases. An unexpected role of caspase-

Uterine Endoplasmic Reticulum Stress and Its Unfolded Protein Response May Regulate Caspase 3 Activation in the Pregnant Mouse Uterus [PDF]

, 2013
We have previously proposed that uterine caspase-3 may modulate uterine contractility in a gestationally regulated fashion. The objective of this study was to determine the mechanism by which uterine caspase-3 is activated and consequently controlled in ...

Roles of the Caspase-11 Non-Canonical Inflammasome in Rheumatic Diseases. [PDF]

Int J Mol Sci
Inflammasomes are intracellular multiprotein complexes that activate inflammatory signaling pathways. Inflammasomes comprise two major classes: canonical inflammasomes, which were discovered first and are activated in response to a variety of pathogen-associated molecular patterns (PAMPs) and danger-associated molecular patterns (DAMPs), and non ...

Spotlight on pyroptosis: role in pathogenesis and therapeutic potential of ocular diseases

Journal of Neuroinflammation, 2022
Pyroptosis is a programmed cell death characterized by swift plasma membrane disruption and subsequent release of cellular contents and pro-inflammatory mediators (cytokines), including IL‐1β and IL‐18.

Caspase-1 Inhibitor Reduces Pyroptosis Induced by Brain Death in Kidney

Frontiers in Surgery, 2021
Brain death (BD) induces an organ-level inflammatory response. However, the underlying mechanisms have not been fully elucidated. Here, we investigated the role of caspase-1-mediated pyroptosis in BD-induced kidney injury in rats.

Caspase-11 Protects Against Bacteria That Escape the Vacuole [PDF]

Science, 2013
Caspase-11–Dependent Pyroptosis Inflammasomes are multiprotein complexes that assemble to initiate immunity to a variety of microorganisms, as well as to sterile tissue injury. Although a role for caspase-1 downstream of inflammasomes is well characterized, the discovery that caspase-1 knockout mice were also deficient in caspase-
