Combining Genome Wide Association Studies and Differential Gene Expression Data Analyses Identifies Candidate Genes Affecting Mastitis Caused by Two Different Pathogens in the Dairy Cow [PDF]

, 2015
Mastitis is a costly disease which hampers the dairy industry. Inflammation of the mammary gland is commonly caused by bacterial infection, mainly Escherichia coli, Streptococcus uberis and Staphylococcus aureus.

Bimetallic Peroxide Nanocomposites‐Driven Redox Dyshomeostasis to Activate Sequential Cuproptosis and Pyroptosis for Amplified Tumor Immunotherapy

Advanced Science, EarlyView.
Hyaluronic acid‐modified bimetallic peroxide nanocomposites (MgO2‐CuO2@HA) are designed for synergistic tumor therapy. The nanocomposites release Mg2+, H2O2, and Cu2+ in tumor cells, induce cuproptosis via Cu+‐mediated protein aggregation, and activate pyroptosis through caspase‐1/gasdermin D pathways for inducing immunogenic cell death, collectively ...

Chemically induced dimerization of GSDMD C-terminal domain blocks GSDMD N-terminal domain-mediated pyroptosis

Cell Death Discovery
Abstract GSDMD is a pyroptosis executioner in which the C-terminal domain completely inhibits the pore-forming ability of the N-terminal domain. Caspase cleavage separates GSDMD into the free C-terminal fragment (GD-CT) and the free N-terminal fragment (GD-NT). Although GD-CT retains the ability to bind with GD-NT, it can no longer completely

Mitochondrial ROS promote macrophage pyroptosis by inducing GSDMD oxidation

Journal of Molecular Cell Biology, 2019
Abstract Disrupted mitochondrial membrane potential (MMP) and reactive oxygen species (ROS) generation are often associated with macrophage pyroptosis. It remains unclear how these forms of mitochondrial dysfunction relate to inflammasome activation and gasdermin-D (Gsdmd) cleavage, two central steps of the pyroptotic process.

E3 ubiquitin ligase SYVN1 is a key positive regulator for GSDMD-mediated pyroptosis

Cell Death and Disease, 2022
Gasdermin D (GSDMD) participates in the activation of inflammasomes and pyroptosis. Meanwhile, ubiquitination strictly regulates inflammatory responses. However, how ubiquitination regulates Gasdermin D activity is not well understood.

Gasdermin D is required for pyroptosis and secretion of interleukin-1β [PDF]

, 2016
炎性小体是细胞内由caspase-1，ASC，NALP等组成的蛋白复合体，也是先天免疫系统的一个重要组成。炎性小体被激活后会促进白介素1β（IL-1β）和IL-18的剪切与分泌，并触发细胞焦亡的发生。细胞焦亡是近年来发现并证实的一种新的程序性细胞死亡方式，其特征为依赖于caspase-1，并伴随有促炎症因子的释放。尽管其在先天免疫和内毒素休克方面扮演着重要角色，但细胞焦亡被诱导发生的机制仍不清楚。本文通过基于CRISPR-Cas9的基因敲除方法鉴定到了gasderminD（GSDMD ...

Inflammasome priming in sterile inflammatory disease [PDF]

, 2017
The inflammasome is a cytoplasmic protein complex that processes interleukins (IL)-1β and IL-18, and drives a form of cell death known as pyroptosis. Oligomerization of this complex is actually the second step of activation, and a priming step must occur

Irradiated Tumor Cell‐Derived Microparticles Activate Systemic Anti‐Tumor Immunity via the STING/NLRP3/GSDMD Axis in Neutrophils

Advanced Science, EarlyView.
Radiotherapy induces tumor cells to release microparticles (RT‐MPs) into the circulation. The mitochondrial DNA carried by these RT‐MPs activates the STING/NLRP3/GSDMD axis in splenic neutrophils, triggering IL‐1β secretion. This, in turn, enhances dendritic cell function and facilitates the formation of cytotoxic T lymphocytes, thereby promoting ...
