Renal segmental metabolism is reflected by the complex distribution of the main energy pathways along the nephron, with fatty acid oxidation preferentially used in the cortex area. Ischemia/reperfusion injury (IRI) is due to the restriction of renal blood flow, rapidly leading to a metabolic switch toward anaerobic conditions. Subsequent unbalance between energy demand and oxygen/nutrient delivery compromises kidney cell functions, resulting in a complex inflammatory cascade including the production of reactive oxygen species (ROS). Renal IRI especially involves lipid accumulation. Lipid peroxidation is one of the major events of ROS-associated tissue injury. Here, we briefly review the current knowledge of renal cell lipid metabolism in normal and ischemic conditions. Next, we focus on renal lipid-associated injury, with emphasis on its mechanisms and consequences during the course of IRI. Finally, we discuss preclinical observations aiming at preventing and/or attenuating lipid-associated IRI.

Background: 5-Fluorouracil (5-FU), one of the mostly commonly used chemotherapeutic agents, frequently induces intestinal mucositis, severely impacting patient quality of life and limiting treatment efficacy. Pectolinarigenin (PEC), a bioactive compound isolated from Chinese medicinal herb Dajitan, exhibits anti-inflammatory, antioxidative, and anticancer properties. However, its protective effect on 5-FU-induced mucositis and the underlying molecular mechanisms remains unclear.

Tri-n-butyl phosphate (TnBP) and tricresyl phosphate (TCP), emerging flame retardants and plasticizers, have garnered increasing attention due to their potential risks to ecosystem. A few researches regarding the toxicological mechanisms of TnBP and TCP had been performed, while molecular-level toxic effects of them and metabolic response using microbial models are the lack of relevant investigation. Thus, we investigated the cytotoxicity, oxidative stress response, and metabolic response in E.

In an era where established lines between cell identities are blurred by intra-lineage plasticity, distinguishing stable from transitional states is critical, especially within Group 1 ILCs, where similarity and plasticity between NK cells and ILC1s obscure their unique contributions to immunity. This study leverages AsGM1-a membrane lipid associated with cytotoxic attributes absent in ILC1s-as a definitive criterion to discriminate between these cell types. Employing this glycosphingolipid signature, we achieved precise delineation of Group 1 ILC diversity across tissues.

Schistosomiasis is the second most important parasitic disease worldwide. Schistosomiasis japonica is a unique species endemic to southern China, and schistosomiasis is characterized by severe liver injury, inflammation, liver granuloma, and subsequent liver fibrosis. However, the pathological mechanism of this disease remains unclear.

Our understanding of the functional heterogeneity of resident versus recruited macrophages in the diseased liver is limited. A population of recruited lipid-associated macrophages (LAMs) has been reported to populate the diseased liver alongside resident Kupffer cells (KCs). However, the precise roles of these distinct macrophage subsets remain elusive.
