Summary: This study investigates the interaction between Hypervirulent Klebsiella pneumoniae (hvKP) infection and the anti-inflammatory immune response gene 1 (IRG1)-itaconate axis. The study reveals that exogenous supplementation of itaconate effectively inhibits excessive inflammation by directly inhibiting SYK kinase. Itaconate also suppresses the classical activation phenotype and macrophage cell death induced by hvKP. In vivo experiments demonstrate that itaconate administration mitigates hvKP-induced disturbances in intestinal immunopathology and homeostasis. These findings provide a promising foundation for the development of innovative therapeutic strategies utilizing itaconate for the treatment of hvKP infections.

Summary: Oxaliplatin, a third-generation platinum-based anticancer drug, causes serious side effects including neuropathy and ototoxicity. The mechanism of oxaliplatin-induced cochlear hair cell death and the involvement of ferroptosis in ototoxicity have not been reported. This study demonstrated that oxaliplatin treatment resulted in lipid peroxidation and ROS accumulation, indicating the occurrence of ferroptosis. Activation of Nrf2 alleviated cochlear hair cell damage by inhibiting ferroptosis, suggesting a new mechanism of oxaliplatin-induced ototoxicity.

Summary: This study explored the protective effect and mechanism of ADSCs exosomes on excessive inflammation-induced injury in pulmonary microvascular endothelial cells (PMVECs). ADSCs exosomes reduced ROS accumulation and cell injury in PMVECs by inhibiting excessive inflammatory response. They also alleviated ferroptosis induced by excessive inflammatory response and upregulated GPX4 expression. Furthermore, specific delivery of miR-125b-5p by ADSCs exosomes inhibited Keap1 and alleviated ferroptosis. In a sepsis model, ADSCs exosomes relieved lung tissue injury, reduced the death rate, and alleviated oxidative stress injury and ferroptosis of lung tissue.

Summary: Ferroptosis and iron-related redox imbalance worsen outcomes of traumatic brain injury (TBI). NRF2, the main transcription factor regulating oxidative stress and neuroinflammation in TBI, has an unclear role in iron-induced post-TBI damage. This study investigated ferroptotic neuronal damage in the injured cortex and observed amelioration with the iron chelator deferoxamine (DFO) in wild-type mice. In Nrf2-knockout (Nrf2(-/-)) mice, more severe ferroptosis and neurological deficits were found. Activation of NRF2 with dimethyl fumarate (DMF) alleviated neural dysfunction in TBI mice, partly due to ferroptosis mitigation induced by TBI. Protein levels of FTH-FTL and FSP1, related to iron metabolism and ferroptotic redox balance, were highly dependent on NRF2 after TBI. Therefore, NRF2 has a neuroprotective effect against TBI-induced ferroptosis through regulation of iron levels and redox status, suggesting its potential use in TBI treatment.

Summary: Acute lung injury (ALI), caused by intrapulmonary or extrapulmonary factors such as pneumonia, shock, and sepsis, disrupts the alveolar-capillary barrier, resulting in pulmonary oedema and microatasis. Currently, there is no effective treatment for ALI, but histone deacetylases (HDACs) show potential as therapeutic targets. This review explores the unique mechanisms of HDACs in different cell types of ALI.

Summary: This study found that uridine metabolism is closely related to combating oxidative stress, and redox imbalance-mediated ferroptosis plays a key role in sepsis-induced acute lung injury (ALI). The results showed that uridine metabolism can alleviate lung injury and inflammation, and inhibit tissue iron levels and lipid peroxidation. Uridine also inhibits macrophage ferroptosis by activating the Nrf2 signaling pathway. Therefore, uridine supplementation may be a potential avenue for ameliorating sepsis-induced ALI by suppressing ferroptosis.
