A review of in vitro genotoxicity studies on titanium dioxide nanoparticles (TiO2 -NPs) published between 2010 and 2016 was performed by France in the framework of the CLP Regulation 1272/2008/EC. Neither the few in vivo studies of low quality nor the larger number of acceptable in vitro studies available for genotoxicity allowed France to conclude on the genotoxicity of TiO2 -NPs. Based on this work, it was decided to compare the acceptable in vitro studies to understand the reasons for the diverging results observed, such as the materials tested or of the protocols used and their inherent interferences...

Ziziphus spina-christi (L.), a traditional Arabian medicinal herb, has been used by Egyptians (Bedouin and Nubian) to treat inflammatory symptoms and swellings, pain, and heat since long. We aimed to investigate whether Ziziphus spina-christi leaf extract (ZSCLE) exerted a myocardial and renal protective effect on mice in which sepsis had been induced with cecal ligation and puncture (CLP). Male C57BL/6 mice were divided randomly into six groups (n = 7): sham-operated group, sham-operated mice treated with ZSCLE (300 mg/kg), CLP-induced sepsis group, ZSCLE (100 mg/kg)-treated group, ZSCLE (200 mg/kg)-treated group, and ZSCLE (300 mg/kg)-treated group...

Specific therapies targeting cellular and molecular events of sepsis induced Acute Lung Injury (ALI) pathogenesis are lacking. We have reported a pivotal role for Nuclear Factors of Activated T cells (NFATc3) in regulating macrophage phenotype during sepsis induced ALI and subsequent studies demonstrate that NFATc3 transcriptionally regulates macrophage CCR2 and TNFα gene expression. Mouse pulmonary microvascular endothelial cell monolayer maintained a tighter barrier function when co-cultured with LPS stimulated NFATc3 deficient macrophages whereas wild type macrophages caused leaky monolayer barrier...

Glucocorticoids (GCs) are used for acute respiratory distress syndrome (ARDS) to improve or prevent lung injury. The mechanisms underlying the effects of GCs involve inadequate GC-receptor (GR)-mediated downregulation of pro-inflammatory factors despite elevated levels of cortisol. Within this context, knowledge of the transcriptional pattern of the GR gene in response to variations in physiological parameters may shed light on this issue. We addressed this problem by measuring plasmatic corticosterone (CCT) levels and assessing GR expression at transcript and protein levels in rats with caecal ligation and puncture (CLP)-induced ARDS-like syndrome treated with dexamethasone and metyrapone...

Group 2 innate lymphoid cells (ILC2) are one of three subgroups of innate lymphoid cells (ILC1, ILC2, and ILC3), and the major ILC population detected in the lungs. The function of ILC2 in the regulation of lung inflammation remains unclear. In the current study, we explored an important role of ILC2 in protecting lung endothelial cell (EC) from pyroptosis in sepsis-induced acute lung inflammation and the underlying mechanism. Using a cecal ligation and puncture (CLP) mouse sepsis model, we demonstrated that IL-33, which is released in response to sepsis, acting through its receptor ST2 mediates ILC2 expansion in the lungs...

Abdominal sepsis is associated with dysfunctional hemostasis. Thrombin generation (TG) is a rate-limiting step in systemic coagulation. Neutrophils can expell neutrophil extracellular traps (NETs) and/or microparticles (MPs) although their role in pathological coagulation remains elusive. Cecal ligation and puncture (CLP)-induced TG in vivo was reflected by a reduced capacity of plasma from septic animals to generate thrombin. Depletion of neutrophils increased TG in plasma from CLP mice. Sepsis was associated with increased histone 3 citrullination in neutrophils and plasma levels of cell-free DNA and DNA-histone complexes and administration of DNAse not only eliminated NET formation but also elevated TG in sepsis...

Background: microRNA-23b (miR-23b) is a multiple functional miRNA. We hypothesize that miR-23b plays a role in the pathogenesis of sepsis. Our study investigated the effect of miR-23b on sepsis induced immunosuppression. Methods: Mice were treated with miR-23b inhibitors by tail vein injection 2 days after cecal ligation puncture (CLP)-induced sepsis. Apoptosis in spleens and apoptotic signals were detected, meanwhile survival was monitored. T cell immunoreactivities were examined in late sepsis...

Amantadine has been shown to reduce anesthesia and surgery-induced neuroinflammation and cognitive dysfunction. It is known that sepsis can impair brain function. We determined whether amantadine-attenuated sepsis-induced neuroinflammation and dysfunction of learning and memory and whether toll-like receptors (TLRs) play a role in the effects. Six- to eight-week-old mice were subjected to cecal ligation and puncture (CLP). Amantadine at 30 mg/kg/day was injected intraperitoneally for 3 days. CU-CPT22, a TLR1/TLR2 inhibitor, at 3 mg/kg/day was injected intraperitoneally for 2 days...

Sepsis-associated encephalopathy (SAE), characterized as diffuse brain dysfunction and neurological manifestations secondary to sepsis, is a common complication in critically ill patients and can give rise to poor outcome, but understanding the molecular basis of this disorder remains a major challenge. Given the emerging role of G protein-coupled receptor 2 (GRK2), first identified as a G protein-coupled receptor (GPCR) regulator, in the regulation of non-GPCR-related molecules contributing to diverse cellular functions and pathology, including inflammation, we tested the hypothesis that GRK2 may be linked to the neuropathogenesis of SAE...

Hypopituitary dwarf mice demonstrate advantages of longevity, but little is known of their colon development and intestinal immunity. Herein we found that Ames dwarf mice have shorter colon and colonic crypts, but larger ratio of mesenteric lymph nodes (MLNs) over body weight than age-matched wild type (WT) mice. In the colonic lamina propria (cLP) of juvenile Ames mice, more inflammatory neutrophils (Ā: 0.15% vs. 0.03% in WT mice) and monocytes (Ā: 7.97% vs. 5.15%) infiltrated, and antigen presenting cells CD11c+ dendritic cells (Ā: 1...

Bacillus subtilis has shown success in antagonizing plant pathogens where strains of the bacterium produce antimicrobial cyclic lipopeptides (CLPs) in response to microbial competitors in their ecological niche. To gain insight into the inhibitory role of these CLPs, B. subtilis strain B9-5 was co-cultured with three pathogenic fungi. Inhibition of mycelial growth and spore germination was assessed and CLPs produced by B. subtilis B9-5 were quantified over the entire period of microbial interaction. B. subtilis B9-5 significantly inhibited mycelial growth and spore germination of Fusarium sambucinum and Verticillium dahliae, but not Rhizopus stolonifer...
