LPS-aggregating proteins GBP1 and GBP2 are each sufficient to enhance caspase-4 activation both in cellulo and in vitro. [PDF]
Significance Sensing gram-negative bacterial lipopolysaccharide by human caspase-4 is critical for host defense to intracellular gram-negative bacterial pathogens.

Inflammation in Hypervolemic Hemodialysis Patients: The Roles of RelB and Caspase-4. [PDF]
Hypervolemia is associated with inflammation in hemodialysis (HD) patients. How hypervolemia triggers inflammation is not entirely known. We initiated a cross-sectional study enrolling 40 hemodialysis patients who were categorized into normovolemic (N; 23) and hypervolemic (H; 17) groups by bioimpedance measurement.

Intracellular replication of Pseudomonas aeruginosa in epithelial cells requires suppression of the caspase-4 inflammasome. [PDF]
Pathogenesis of Pseudomonas aeruginosa infections can include bacterial survival inside epithelial cells. Previously, we showed that this involves multiple roles played by the type three secretion system (T3SS), and specifically the effector ExoS.

Caspase-4/11 exacerbates disease severity in SARS-CoV-2 infection by promoting inflammation and immunothrombosis. [PDF]
Significance We report the discovery of fundamental roles for the noncanonical inflammasome molecule Caspase-4/11 in promoting pathological inflammatory and prothrombotic pathways in severe acute respiratory syndrome coronavirus 2 (SARS–CoV-2) infections.

Summary: The non-canonical caspase-4 and canonical NLRP3 inflammasomes are both activated by intracellular lipopolysaccharide (LPS), but the crosstalk between these two pathways remains unclear.

Bexarotene-induced cell death in ovarian cancer cells through Caspase-4-gasdermin E mediated pyroptosis. [PDF]
Bexarotene selectively activates retinoid X receptor, which is a commonly used anticancer agent for cutaneous T-cell lymphoma. In this study, we aimed to investigate the anticancer effect of bexarotene and its underlying mechanism in ovarian cancer in ...

Pyroptosis in Endothelial Cells and Extracellular Vesicle Release in Atherosclerosis via NF-κB-Caspase-4/5-GSDM-D Pathway. [PDF]
Background: Pyroptosis, an inflammatory cell death, is involved in the progression of atherosclerosis. Pyroptosis in endothelial cells (ECs) and its underlying mechanisms in atherosclerosis are poorly understood.

Evolution-inspired redesign of the LPS receptor caspase-4 into an interleukin-1β converting enzyme. [PDF]
Caspase-4 homologs can naturally evolve or be synthetically engineered to directly link cytosolic LPS detection to IL-1β secretion. Multitasking by caspases Caspases are innate immune enzymes that regulate activation of inflammasomes and cell death ...

Pyroptosis: A Common Feature of Immune Cells of Haemodialysis Patients
NLRP-3 inflammasome activation can result in interleukin-1β (IL-1β) release and inflammatory cell death (pyroptosis). Caspase-1 is able to trigger both processes.
