Contamination of nanoparticles by endotoxin: evaluation of different test methods

Particle and Fibre Toxicology, 2012
Background Nanomaterials can be contaminated with endotoxin (lipopolysaccharides, LPS) during production or handling. In this study, we searched for a convenient in vitro method to evaluate endotoxin contamination in nanoparticle samples. We assessed the

Endotoxemia and human liver transplantation [PDF]

, 1989
Ninety liver transplantations were performed in 81 patients. Plasma endotoxin was measured preoperatively, at the end of the anhepatic phase, and on postoperative days 1, 3, and 7.

PD‐L1‐Binding Antigen Presenters: Redirecting Vaccine‐Induced Antibodies for Cancer Immunotherapy

Advanced Science, EarlyView.
The PBAP‐gE complex anchors gE antigen to PD‐L1 on tumor cells. Vaccine‐induced anti‐gE antibodies simultaneously engage FcγRIIIa on NK cells and tumor‐bound PBAP‐gE, triggering NK cell activation and antibody‐dependent cellular cytotoxicity, thereby selectively eliminating PD‐L1–expressing tumor cells.

Environmental Exposure to Endotoxin and Decreased Risk of Childhood Atopy

Allergology International, 2005
The hygiene hypothesis implies, in immunological terms, that microbial stimulation in early life skews the immune system towards the development of a T helper type 1 (Th1)-type lymphocyte population, and away from a T helper type 2 (Th2)-type development

Identifying Cytokine Motif‐Containing, Immunomodulatory Bacterial Proteins in Human Gut Microbiome

Advanced Science, EarlyView.
By building and constructing HMM (Upper left, blue), the authors identify CMCPs in bacteria genomes and CRC related metagenomes and enriched CRC‐related CMCPs (Upper right, blue). They analyze sequence and structural similarity of hits (Lower left, green), test function with engineered EcN delivered to tumors in a mouse tumor model (Lower right, pink ...

Oil‐Coated Nanoplastics Induce Rapid Membrane Disruption and Severe Intestinal Injury

Advanced Science, EarlyView.
Oil‐rich food contact dramatically amplifies MNP release from plastic takeout containers, producing oil‐coated nanoplastics with altered surface properties and rapid membrane‐disruptive effects. These particles cause severe intestinal barrier damage and immune dysfunction in mice, and risk modeling suggests that long‐term gastrointestinal burdens may ...

Cascade‐Responsive MXene@Cu‐MOF Heterostructure Integrates Antioxidant Activity, Infection Control, and Vascularization for Tracheal Repair

Advanced Science, EarlyView.
A cascade‐responsive MXene@Cu‐MOF/GelMA hydrogel is engineered as a “skeleton–backpack” platform for extensive tracheal repair. The MXene framework scavenges postoperative ROS and converts NIR light into mild hyperthermia, while the Cu‐MOF component provides pH/NIR‐responsive Cu2+ dosing for infection control, angiogenesis, and chondrogenesis.

Inhaled Interleukin-10 before and after induction of experimental endotoxemia in the rat : effects on the inflammatory response [PDF]

, 2007
To determine the effects of inhaled IL-10 at different doses and different time points on the pulmonary and systemic inflammatory response during endotoxemia, 48 ventilated, anaesthetized rats (mean body weight ± standard deviation, 500 ± 33g) were ...

Loss of VMP1 Impairs Tight Junction Recycling and Aggravates Intestinal Barrier Dysfunction in Inflammatory Bowel Disease

Advanced Science, EarlyView.
This study identifies vacuole membrane protein 1 (VMP1) as a critical regulator of intestinal epithelial barrier homeostasis. VMP1 facilitates the recruitment of CORO1C to late endosomes, supporting Retromer‐mediated recycling of the tight junction protein Occludin.
