We have recently proposed that the interaction between food components and nanoparticles (NPs) should be considered when evaluating the toxicity of NPs. In the present study, we used THP-1 differentiated macrophages as a model for immune cells and investigated the combined toxicity of low levels of palmitate (PA; 10 or 50μM) and ZnO NPs. The results showed that PA especially at 50μM changed the size, Zeta potential and UV-vis spectra of ZnO NPs, indicating a possible coating effect. Up to 32μg/mL ZnO NPs did not significantly affect mitochondrial activity, intracellular reactive oxygen species (ROS) or release of interleukin 6 (IL-6), but significantly impaired lysosomal function as assessed by neutral red uptake assay and acridine orange staining...

Titanium dioxide nanoparticles (TiO2 NPs) are used in many fields, such as paints, medicine additives, food additives, sunscreens and agriculture. The aim of this study was to investgate the mechanism behind the formation of inflammation induced by TiO2 NPs. ICR mice were exposed to TiO2 NPs through intragastric administration at 2.5, 5 and 10 mg/kg body weight every day for 90 consecutive days. The experiment suggested that long-term exposure to TiO2 NPs resulted in an obvious inflammatory response in mice lung tissues, which led to a thickened alveoli septum, lung hyperaemia, and titanium accumulation...

There is evidence that immune-inflammatory and oxidative and nitrosative stress (O&NS) pathways play a role in the pathophysiology of myalgic encephalomyelitis (ME)/chronic fatigue syndrome (CFS). There is also evidence that these neuroimmune diseases are accompanied by hypothalamic-pituitary-adrenal (HPA) axis hypoactivity as indicated by lowered baseline glucocorticoid levels. This paper aims to review the bidirectional communications between immune-inflammatory and O&NS pathways and HPA axis hypoactivity in ME/CFS, considering two possibilities: (a) Activation of immune-inflammatory pathways is secondary to HPA axis hypofunction via attenuated negative feedback mechanisms, or (b) chronic activated immune-inflammatory and O&NS pathways play a causative role in HPA axis hypoactivity...

Tetrandrine (TET) is a bis-benzylisoquinoline alkaloid, which is isolated from a Chinese medicinal herb with antioxidant and anti-inflammatory activities. In this study, we investigated the effects of TET on oxygen-glucose-serum deprivation/reoxygenation (OGSD/R)-induced injury in rat spinal cord astrocytes, which mimics hypoxic/ischemic conditions in vivo. MTT and LDH assays indicated that cell viability was distinctly reduced and LDH leakage was elevated after OGSD/R exposure, which were dose-dependently reversed by pretreatment with TET (0...

BACKGROUND: Diagnosis of engraftment syndrome (ES) following allogeneic hematopoietic stem cell transplantation (HSCT) can be a challenge due to the systemic presentation and alternative etiologies. With a goal of establishing biomarkers to more accurately distinguish ES, we prospectively analyzed levels of cytokines during HSCT. PROCEDURES: We performed a prospective study of children ≤21 years who underwent allogeneic HSCT. Blood samples for interleukin (IL)-6, IL-8, IL-10, IL-1b, IL-12p70, interferon-γ, tumor necrosis factor alpha (TNF-α) and procalcitonin were obtained from each subject prior to conditioning, at day 0, and then biweekly through engraftment and at days 30, 60 and 100...

Strawberries, rich in anthocyanins, attenuate meal-induced postprandial increases in inflammation and oxidative stress as well as improved post-meal insulin responses. While previous studies have focused on the health effects of strawberry consumption ingested with a meal, this study aimed to determine if consuming strawberries at alternative times near a meal would influence meal-induced oxidative-immuno-metabolic outcomes. Fourteen overweight healthy adults participated in a 3-arm, single-blinded, crossover clinical trial delivering a strawberry drink at 1 of 3 different time points: 2 hours before a standard meal, with the meal, or 2 hours after the meal...

Advanced glycation end products (AGEs) are major inflammatory mediators in diabetes, affecting atherosclerosis progression via macrophages. Metformin slows diabetic atherosclerosis progression through mechanisms that remain to be fully elucidated. The present study of murine bone marrow derived macrophages showed that (1) AGEs enhanced proinflammatory cytokines (interleukin-1β (IL-1β), IL-6, and tumor necrosis factor-α (TNF-α)) mRNA expression, RAGE expression, and NFκB activation; (2) metformin pretreatment inhibited AGEs effects and AGEs-induced cluster designation 86 (CD86) (M1 marker) expression, while promoting CD206 (M2 marker) surface expression and anti-inflammatory cytokine (IL-10) mRNA expression; and (3) the AMPK inhibitor, Compound C, attenuated metformin effects...

The mistletoe Loranthus parasiticus has been used as a compound for traditional medicine in Northeast Asia for a long time and is known to possess neuroprotective action. Nonetheless, the effect of Loranthus parasiticus on allergic responses remains unknown. In the present study, we evaluated whether the water extract of Loranthus parasiticus (LPE) could inhibit IgE-mediated allergic responses in RBL-2H3 cells. LPE inhibited the release of β-hexosaminidase (IC50, 184.5 μg/mL) and the formation of tumor necrosis factor-α (IC50, 84...

Neonatal toxic shock syndrome-like exanthematous disease (NTED) is a newly recognized neonatal infectious disease, caused by the superantigen toxic shock syndrome toxin-1 (TSST-1). TSST-1 is mainly produced by methicillin-resistant Staphylococcus aureus, and the immune responses to TSST-1 are known to cause toxic shock syndrome, a life-threatening infectious disease. The clinical symptoms of NTED are skin rash, fever, and thrombocytopenia, but severe thrombocytopenia is rare in term infants with NTED. Although the cause of NTED is the same as that of toxic shock syndrome, the clinical symptoms of NTED are milder than toxic shock syndrome...

Recombinant interleukin-2 (rIL-2) is associated with objective responses in 15-20 % of patients with metastatic melanoma and renal cell carcinoma. More recently, rIL-2 has also demonstrated improved clinical activity in patients with melanoma. Given the toxicity of high-dose rIL-2 and the availability of many new immunotherapy agents, it has been suggested that lower doses of rIL-2 may be preferred for combination clinical studies. In order to determine the impact of low doses of rIL-2 on anti-tumor immunity and therapeutic effectiveness, we challenged C57BL/6 mice with poorly immunogenic B16-F10 melanoma and treated them with varying doses of rIL-2 (range 10(3)-10(5) IU)...
