Apoptosis, pyroptosis, and necrosis: mechanistic description of dead and dying eukaryotic cells
Susan L. Fink,Brad T. Cookson +1 more
TLDR
A wide variety of pathogenic microorganisms have been demonstrated to cause eukaryotic cell death, either as a consequence of infecting host cells or by producing toxic products, and apoptosis in many of these systems is characterized as apoptosis.Abstract:
A wide variety of pathogenic microorganisms have been demonstrated to cause eukaryotic cell death, either as a consequence of infecting host cells or by producing toxic products. Pathogen-induced host cell death has been characterized as apoptosis in many of these systems. It is increasingly beingread more

Origin and Physiological Roles of Inflammation
TL;DR: This work has shown that tissue stress or malfunction induces an adaptive response that is intermediate between the basal homeostatic state and a classic inflammatory response, which is referred to here as para-inflammation.

The trinity of COVID-19: immunity, inflammation and intervention.
Matthew Zirui Tay,Chek Meng Poh,Laurent Rénia,Laurent Rénia,Paul A. MacAry,Lisa F. P. Ng,Lisa F. P. Ng,Lisa F. P. Ng +7 more
TL;DR: The interaction of SARS-CoV-2 with the immune system and the subsequent contribution of dysfunctional immune responses to disease progression is described and the implications of these approaches for potential therapeutic interventions that target viral infection and/or immunoregulation are highlighted.
Journal ArticleDOI
Pyroptosis: host cell death and inflammation
TL;DR: Pyroptosis, or caspase 1-dependent cell death, is inherently inflammatory, is triggered by various pathological stimuli, such as stroke, heart attack or cancer, and is crucial for controlling microbial infections.

Adipocyte death defines macrophage localization and function in adipose tissue of obese mice and humans

TL;DR: It is demonstrated that >90% of all macrophages in WAT of obese mice and humans are localized to dead adipocytes, where they fuse to form syncytia that sequester and scavenge the residual “free” adipocyte lipid droplet and ultimately form multinucleate giant cells, a hallmark of chronic inflammation.
Journal ArticleDOI
The Inflammasomes: Guardians of the Body
TL;DR: The role of NLRs, and in particular the inflammasomes, in the recognition of microbial and danger components and the role they play in health and disease are discussed.

Apoptosis: a basic biological phenomenon with wide-ranging implications in tissue kinetics.
TL;DR: Apoptosis seems to be involved in cell turnover in many healthy adult tissues and is responsible for focal elimination of cells during normal embryonic development, and participates in at least some types of therapeutically induced tumour regression.
Journal ArticleDOI
Glucocorticoid-induced thymocyte apoptosis is associated with endogenous endonuclease activation
TL;DR: It is shown here that this morphological change is closely associated with excision of nucleosome chains from nuclear chromatin, apparently through activation of an intracellular, but non-lysosomal, endonuclease.

Release of chromatin protein HMGB1 by necrotic cells triggers inflammation
TL;DR: It is reported that Hmgb1-/- necrotic cells have a greatly reduced ability to promote inflammation, which proves that the release of HMGB1 can signal the demise of a cell to its neighbours, and cells undergoing apoptosis are programmed to withhold the signal that is broadcast by cells that have been damaged or killed by trauma.

Development by Self-Digestion: Molecular Mechanisms and Biological Functions of Autophagy
Beth Levine,Daniel J. Klionsky +1 more
TL;DR: This review summarizes the current knowledge about the molecular machinery of autophagy and the role of the autophagic machinery in eukaryotic development and identifies a set of evolutionarily conserved genes that are essential forAutophagy.

Apoptosis, oncosis, and necrosis : an overview of cell death
Guido Majno,Isabelle Joris +1 more
TL;DR: Some of the typical features of apoptosis are discussed, such as budding (as opposed to blebbing and zeiosis) and the inflammatory response, and stands in contrast to apoptosis, which leads to necrosis with karyorhexis and cell shrinkage.
