Calcium phosphate particles stimulate interleukin-1β release from human vascular smooth muscle cells: A role for spleen tyrosine kinase and exosome release [PDF]
Aims: Calcium phosphate (CaP) particle deposits are found in several inflammatory diseases including atherosclerosis and osteoarthritis. CaP, and other forms of crystals and particles, can promote inflammasome formation in macrophages leading to caspase ...

Caspase-1 engagement and TLR-induced c-FLIP expression suppress ASC/caspase-8-dependent apoptosis by inflammasome sensors NLRP1b and NLRC4 [PDF]
The caspase activation and recruitment domain (CARD)-based inflammasome sensors NLRP1b and NLRC4 induce caspase-1-dependent pyroptosis independent of the inflammasome adaptor ASC.

Pseudomonas aeruginosa pilin activates the inflammasome [PDF]
IL-1 beta is produced from inactive pro-IL-1 beta by activation of caspase-1 brought about by a multi-subunit protein platform called the inflammasome. Many bacteria can trigger inflammasome activity through flagellin activation of the host protein NLRC4.

Caspase-1 inflammasomes in infection and inflammation [PDF]
AbstractNucleotide-binding and oligomerization domain-like receptors (NLRs) constitute a family of germline-encoded pattern-recognition receptors, which allow the host to respond rapidly to a wide variety of pathogenic microorganisms. Here, we discuss recent advances in the study of a subset of NLRs, which control the activation of caspase-1 through ...

Non-classical ProIL-1beta activation during mammary gland infection is pathogen-dependent but caspase-1 independent [PDF]
Infection of the mammary gland with live bacteria elicits a pathogen-specific host inflammatory response. To study these host-pathogen interactions wild type mice, NF-kappaB reporter mice as well as caspase-1 and IL-1beta knockout mice were ...

Caspase-1 initiates apoptosis in the absence of gasdermin D
Caspase-1 activated in inflammasomes triggers a programmed necrosis called pyroptosis, which is mediated by gasdermin D (GSDMD). However, GSDMD-deficient cells are still susceptible to caspase-1-mediated cell death.

Activation of Caspase-1 in the Nucleus Requires Nuclear Translocation of Pro-caspase-1 Mediated by Its Prodomain [PDF]
The interleukin-1beta-converting enzyme-like protease precursor, pro-caspase-1, has an N-terminal prodomain that is removed during cleavage activation of the protease. Here we show that tumor necrosis factor treatment of HeLa cells induced apoptosis without detectable proteolytic activation of caspase-1 in the cytosol.

Summary: Zoonotic pathogens, such as COVID-19, reside in animal hosts before jumping species to infect humans. The Carnivora, like mink, carry many zoonoses, yet how diversity in host immune genes across species affect pathogen carriage is poorly ...

Caspase-1 self-cleavage is an intrinsic mechanism to terminate inflammasome activity
Host-protective caspase-1 activity must be tightly regulated to prevent pathology, but mechanisms controlling the duration of cellular caspase-1 activity are unknown.

Caspase-1 Mediates Resistance in Murine Melioidosis [PDF]
ABSTRACT The gram-negative rod Burkholderia pseudomallei is the causative agent of melioidosis, a potentially fatal disease which is endemic in tropical and subtropical areas. The bacterium multiplies intracellularly within the cytosol, induces the formation of actin tails, and can spread directly from ...
