High‐Throughput 3D Matrigel‐based Droplet Microfluidics for Single‐Cell Function‐to‐Omics Analysis of Cytotoxic Immune Cells in Solid Tumor Interactions

Advanced Materials Technologies, EarlyView.
A 3D Matrigel‐based droplet microfluidics platform that allows physiologically relevant analysis of single immune‐tumor interactions in solid tumors. By integrating real‐time functional imaging with fluorescence‐activated droplet sorting and RNA sequencing, the system links immune cytotoxic behavior to transcriptomic profiles, providing a scalable ...

Protease-activated receptor-1 activation by granzyme B causes neurotoxicity that is augmented by interleukin-1β

Journal of Neuroinflammation, 2017
Background The cause of neurodegeneration in progressive forms of multiple sclerosis is unknown. We investigated the impact of specific neuroinflammatory markers on human neurons to identify potential therapeutic targets for neuroprotection against ...

A20 controls macrophage to elicit potent cytotoxic CD4(+) T cell response. [PDF]

PLoS ONE, 2012
Emerging evidence indicates that CD4(+) T cells possess cytotoxic potential for tumor eradication and perforin/granzyme-mediated cytotoxicity functions as one of the important mechanisms for CD4(+) T cell-triggered cell killing.

Gold Nanoparticles and Graphene Oxide Flakes Enhance Cancer Cells’ Phagocytosis through Granzyme-Perforin-Dependent Biomechanism

Nanomaterials, 2021
The study aimed to investigate the roles of gold nanoparticles (GNPs) and graphene oxide flakes (GOFs) as phagocytosis enhancers against cancer cells. The nanomaterials were characterized through SEM and UV-VIS absorptions.

FAPα+ Macrophages Orchestrate Immune Evasion in Multiple Myeloma by Dual Regulation of PD‐L1 and T Cell Senescence

Advanced Science, EarlyView.
Fibroblast activation protein alpha‐positive (FAPα+) macrophages, a distinct subset of multiple myeloma (MM)‐associated macrophages, drive immune evasion in MM through multi‐faceted mechanisms. FAPα physically interacts with vimentin (VIM) and triggers its phosphorylation at the S72 residue, which in turn induces PD‐L1 transcription. Additionally, FAPα

RNA-Seq analysis of chikungunya virus infection and identification of granzyme A as a major promoter of arthritic inflammation.

PLoS Pathogens, 2017
Chikungunya virus (CHIKV) is an arthritogenic alphavirus causing epidemics of acute and chronic arthritic disease. Herein we describe a comprehensive RNA-Seq analysis of feet and lymph nodes at peak viraemia (day 2 post infection), acute arthritis (day 7)

Identification and annotation of bovine granzyme genes reveals a novel granzyme encoded within the trypsin-like locus [PDF]

Immunogenetics, 2018
Granzymes are a family of serine proteases found in the lytic granules of cytotoxic T lymphocytes and natural killer (NK) cells, which are involved in killing of susceptible target cells. Most information on granzymes and their enzymatic specificities derive from studies in humans and mice. Although granzymes shared by both species show a high level of

Tailoring Vascular‐Immune Homeostasis via Manganese‐DNA Complex‐Armed Immunogenic Extracellular Vesicles for Pancreatic Cancer Immunotherapy

Advanced Science, EarlyView.
This study demonstrates that Mn2⁺–tumor DNA complexes encapsulated in dendritic cell (DC)– derived immunogenic extracellular vesicles (EVDC@Mn‐DNA) act as a DC‐specific cGAS– STING activator. EVDC@Mn‐DNA treatment enhances intratumoral DC activation, improves tumor vascular function, promotes CD8⁺ T cell activity, and suppresses pancreatic tumor growth,

Expression of granzyme A in human polymorphonuclear neutrophils

Immunology, 2007
SummaryPolymorphonuclear neutrophils (PMNs) are the first line of defence against invading pathogens. They contain a multitude of antimicrobial and potentially cytotoxic substances packed in granules and secretory vesicles. Here, we show that granzyme A (GzmA) is constitutively expressed in human PMNs, but not in the promyelocytic cell line HL‐60, by ...
