Effector mechanisms of non-canonical inflammasome activation

, 2018
Our body constantly faces all kinds immunological challenges, ranging from sterile wounds to non-pathogenic and sometimes pathogenic microorganisms. The innate immune system represents the first line of defense against these challenges. It is capable of detecting invading microorganisms and tissue damage by conserved, germline-encoded pattern ...

Glycopolymeric nanoparticles transported by activated platelets protect ischemic myocardium by alleviating PANoptosis through targeting macrophage Dectin‐1

BMEMat, EarlyView.
NP‐SF, designed to target macrophage Dectin‐1 and activated platelets, selectively accumulated in ischemic myocardium, where it was taken up by macrophages after platelet hitchhiking. By inhibiting NLRC5‐related PANoptosis, NP‐SF significantly attenuated pathological damage, and effectively preserved cardiac function in a murine ischemia–reperfusion ...

Mesenchymal Stromal Cells Directly Promote Inflammation by Canonical NLRP3 and Non-canonical Caspase-11 Inflammasomes

EBioMedicine, 2018
Mesenchymal stromal cells (MSCs) based therapy is a promising approach to treat inflammatory disorders. However, therapeutic effect is not always achieved. Thus the mechanism involved in inflammation requires further elucidation.

Intravenous Lipopolysaccharide Challenge in Healthy Participants Reveals Pharmacodynamic Markers in Blood and Bone Marrow for Early‐Phase Oncology Drug Development

Clinical Pharmacology &Therapeutics, EarlyView.
Demonstrating pharmacological effects in early‐phase oncology clinical trials remains challenging, largely due to the lack of robust pharmacodynamic markers. Lipopolysaccharide (LPS) is used as an immune challenge agent in healthy participants to study drugs for autoimmune conditions.

El Tor Biotype Vibrio cholerae Activates the Caspase-11-Independent Canonical Nlrp3 and Pyrin Inflammasomes

Frontiers in Immunology, 2019
Vibrio cholerae is a Gram-negative enteropathogen causing potentially life-threatening cholera disease outbreaks, for which the World Health Organization currently registers 2–4 million cases and ~100.000 cholera-associated deaths annually worldwide ...

Human GBP1 binds LPS to initiate assembly of a caspase-4 activating platform on cytosolic bacteria

Nature Communications, 2020
Detection of LPS derived from Gram-negative bacteria by innate immune receptors is a critical step in the host response. Here Santos and colleagues show human GBP1 binds to LPS resulting in non-canonical inflammasome activation.

The role of the host—Neutrophil biology

Periodontology 2000, EarlyView., 2023
Abstract Neutrophilic polymorphonuclear leukocytes (neutrophils) are myeloid cells packed with lysosomal granules (hence also called granulocytes) that contain a formidable antimicrobial arsenal. They are terminally differentiated cells that play a critical role in acute and chronic inflammation, as well as in the resolution of inflammation and wound ...

Bile acid metabolism and signaling in human and animal health: A One Health perspective

iMetaOmics, EarlyView.
Bile acids maintain host homeostasis through enterohepatic circulation, microbial transformation, and bile acid receptor signaling, thereby regulating glucose and lipid metabolism, intestinal barrier integrity, and immunity. These effects support human disease intervention and health‐oriented animal production, reducing drug dependence and residue ...

Microbiome and aging: Trajectories of microbiome age across human ecosystems and their systemic effects

iMeta, EarlyView.
Microbiome age (MA) has emerged as an innovative biomarker of biological aging, reflecting host aging trajectories through dynamic alterations in microbial composition, function, and host–microbe interactions across multiple body ecosystems. Diverse computational strategies—including traditional machine learning, deep learning, and multi‐omics ...

A New Paradigm: 46 Structural Cell Types Function as Environment‐Supporting Innate Immune Cells, With Endothelial and Vascular Smooth Muscle Cells as Key Prototypes

iNew Medicine, EarlyView.
ABSTRACT The scope, organization, and biological significance of innate immune functions across structural cell types remain poorly defined. To address these fundamental knowledge gaps, we analyzed experimental data of transcriptomes generated by our group and others.
