The role of NLRP3 inflammasome activation in proinflammatory and cytotoxic effects of metal nanoparticles.

Exposure to metal nanoparticles (NPs) is known to induce inflammatory responses in various tissues, thus limiting their therapeutic potential. NOD-like receptor protein 3 (NLRP3) inflammasome activation is an essential component of innate immunity playing a significant role in inflammation and development of inflammatory diseases. Therefore, the objective of the present review was to summarize data on the role of NLRP3 inflammasome in proinflammatory effects induced by metal NPs, and to discuss the underlying molecular mechanisms, including its dependence on the physical and chemical properties of metal NPs.

Developmental exposure to cobalt chloride affected mouse testis via altered iron metabolism in adulthood.

Inroduction: Cobalt (Co) is known to interfere with iron (Fe) metabolism that is essential for differentiating male germ cells. Our aim was to study the effect of developmental chronic cobalt exposure on mouse testis through changes in iron homeostasis in adulthood.

Methods: Pregnant ICR mice were exposed to 75 mg (low dose) or 125 mg (high dose)/kg b.

Effects of Salinomycin and Deferiprone on Lead-Induced Changes in the Mouse Brain.

Lead (Pb) is a highly toxic heavy metal that has deleterious effects on the central nervous system. This study aimed to investigate the effects of salinomycin (Sal) and deferiprone (DFP) on brain morphology and on the content of some essential elements in Pb-exposed mice. Adult male Institute of Cancer Research (ICR) mice were exposed to a daily dose of 80 mg/kg body weight ( b.

Effects of subacute cadmium exposure and subsequent deferiprone treatment on cadmium accumulation and on the homeostasis of essential elements in the mouse brain.

Introduction: Cadmium (Cd) is а hazardous multi-organ toxin. In this study, we provide the first results about the effect of oral administration of deferiprone (DFP) on Cd accumulation and on the homeostasis of essential elements in the brain of Cd-exposed mice.

Methods: Adult Institute of Cancer Research (ICR) male mice were randomized into four experimental groups: untreated controls - administered distilled water for 28 days; Cd-exposed group - exposed to 18 mg/kg body weight (b.

Ferroptosis as a mechanism of non-ferrous metal toxicity.

Ferroptosis is a recently discovered form of regulated cell death, implicated in multiple pathologies. Given that the toxicity elicited by some metals is linked to alterations in iron metabolism and induction of oxidative stress and lipid peroxidation, ferroptosis might be involved in such toxicity. Although direct evidence is insufficient, certain pioneering studies have demonstrated a crosstalk between metal toxicity and ferroptosis.
