Selenium Ameliorates Aluminum Poisoning-Induced Impaired Production of Neutrophil Extracellular Traps in Chicken.

Neutrophil extracellular traps (NETs) are released by neutrophils to modulate the immune response. Aluminum (Al) poisoning is linked to immunotoxicity, and selenium (Se) can maintain immune homeostasis. In this study, we investigated the toxic effects of Al on the release of NETs, the antagonistic effect of Se on Al-induced toxicity, and the potential molecular mechanisms underlying these processes.

Truncated M13 phage for smart detection of E. coli under dark field.

Background: The urgent need for affordable and rapid detection methodologies for foodborne pathogens, particularly Escherichia coli (E. coli), highlights the importance of developing efficient and widely accessible diagnostic systems. Dark field microscopy, although effective, requires specific isolation of the target bacteria which can be hindered by the high cost of producing specialized antibodies.

A preliminary study on the pathology and molecular mechanism of fumonisin B nephrotoxicity in young quails.

Fumonisin B (FB) is a widely present mycotoxin that accumulates in biological systems and poses a health risk to animals. However, few studies have reported the molecular mechanism by which FB induces nephrotoxicity. The aim of this study was to assess the extent of nephrotoxicity during FB exposure and the possible molecular mechanisms behind it.

Selenium-rich yeast counteracts the inhibitory effect of nanoaluminum on the formation of porcine neutrophil extracellular traps.

Aluminum is widely used in daily life due to its excellent properties. However, aluminum exposure to the environment severely threatens animal and human health. Conversely, selenium (Se) contributes to maintaining the balance of the immune system.

Fumonisin B promotes germ cells apoptosis associated with oxidative stress-related Nrf2 signaling in mice testes.

Fumonisins (FBs) are widespread Fusarium toxins commonly found in corn. This study aimed to establish the mechanism of oxidative stress via the Nrf2 signaling pathway associated with FB-induced toxicity in mice testis. Male mice were fed with 5 mg/kg FB diet for 21 or 42 days, the expression of inflammatory related genes, apoptosis related genes and Nrf2 pathway genes were detected by RT-qPCR, Western blot and immunohistochemical.

Antagonistic Effect of Selenium on Fumonisin B1 Promotes Neutrophil Extracellular Traps Formation in Chicken Neutrophils.

Neutrophils are an important component of the innate immune system, and one of their defense mechanisms, neutrophil extracellular traps (NETs), is a hot topic of the current research. This study explored the effects of fumonisin B1 (FB1) on chicken neutrophil production of NETs and its possible molecular mechanism of action. Scanning electron microscopy and fluorescence microscopy were used to observe morphological changes in neutrophils, and a fluorescence microplate reader was used to detect reactive oxygen species (ROS) and extracellular DNA release from neutrophils.
