The AIM2 inflammasome is critical for innate immunity to Francisella tularensis. [PDF]

, 2010
Francisella tularensis, the causative agent of tularemia, infects host macrophages, which triggers production of the proinflammatory cytokines interleukin 1beta (IL-1beta) and IL-18. We elucidate here how host macrophages recognize F.

The pyrin inflammasome in host-microbe interactions.

Current Opinion in Microbiology, 2020
Pyrin is an inflammasome sensor in phagocytes that is activated in response to bacterial toxins and effectors that modify RhoA. Pathogen effector-triggered pyrin activation is analogous to an indirect guard mechanism in plants. Pyrin activation appears to be triggered when RhoA GTPases in a host cell are prevented from binding downstream signaling ...

Familial Mediterranean Fever and COVID-19: Friends or Foes?

Frontiers in Immunology, 2020
Familial Mediterranean Fever (FMF) and COVID-19 show a remarkable overlap of clinical symptoms and similar laboratory findings. Both are characterized by fever, abdominal/chest pain, elevation of C-reactive protein, and leukocytosis.

Let's get this pyrin started! [PDF]

Journal of Biological Chemistry, 2019
Inflammasomes enable cells to respond to pathogens or biological damage, but the specific signals being used to convey these messages are not always clear. A new paper identifies two potential microbiota-derived metabolites, the bile acid analogues BAA485 and BAA473, as the first small molecules to activate the pyrin inflammasome. These results suggest

Enhanced mitochondrial activity reshapes a gut microbiota profile that delays NASH progression

Hepatology, EarlyView., 2022
Improved mitochondrial activity, due to the lack of methylation‐controlled J protein (MCJ), creates a specific microbiota signature that when transferred through cecal microbiota transplantation delays NASH progression by restoring the gut‐liver axis and enhancing hepatic fatty acid oxidation.

Trimethylamine-N-Oxide Promotes Vascular Calcification Through Activation of NLRP3 (Nucleotide-Binding Domain, Leucine-Rich-Containing Family, Pyrin Domain-Containing-3) Inflammasome and NF-κB (Nuclear Factor κB) Signals

Arteriosclerosis, Thrombosis and Vascular Biology, 2020
Supplemental Digital Content is available in the text. Objectives: Vascular calcification is highly prevalent in patients with chronic kidney disease. Increased plasma trimethylamine N-oxide (TMAO), a gut microbiota-dependent product, concentrations are ...

The effect of colchicine on pyrin and pyrin interacting proteins

Journal of Cellular Biochemistry, 2012
AbstractMEFV which encodes pyrin, cause familial Mediterranean fever (FMF), the most common auto‐inflammatory disease. Pyrin is believed to be a regulator of inflammation, though the nature of this regulatory activity remains to be identified.

AIF1+CSF1R+ MSCs, induced by TNF‐α, act to generate an inflammatory microenvironment and promote hepatocarcinogenesis

Hepatology, EarlyView., 2022
Mesenchymal stem cells subset, educated by TNF‐α, are involved to generate inflammatory microenvironment and promote hepatocarcinogenesis Abstract Background and Aims Increasing evidence suggests that mesenchymal stem cells (MSCs) home to injured local tissues and the tumor microenvironment in the liver.

Deficiency of the purinergic receptor 2X7 attenuates nonalcoholic steatohepatitis induced by high-fat diet. possible role of the NLRP3 Inflammasome [PDF]

, 2017
Molecular mechanisms driving transition from simple steatosis to nonalcoholic steatohepatitis (NASH), a critical step in the progression of nonalcoholic fatty liver disease (NAFLD) to cirrhosis, are poorly defined. This study aimed at investigating the
