Summary: Hyaluronan (HA) is a natural compound that is found on the cell surface and tissue extracellular matrix. It is synthesized by enzymes and degraded by other substances. HA has different effects on the body depending on its molecular weight, with high molecular weight HA being anti-inflammatory and low molecular weight HA being pro-inflammatory. Reactive oxygen species (ROS) can degrade HA and affect vascular integrity, while HA can also play a role in wound healing. Understanding the interactions between ROS and HA is an important research topic.

Summary: This study found that mitochondria-derived reactive oxygen species (ROS) contribute to renal cell ferroptosis during lipopolysaccharide (LPS)-induced acute kidney injury (AKI). Inhibition of ferroptosis and scavenging of mitochondrial ROS with specific inhibitors, ferrostatin-1 and MitoQ, respectively, attenuated renal lipid peroxidation, ferroptosis-characteristic mitochondrial damage, and renal cell death. These findings suggest that mitochondria-targeted antioxidants may be potential therapeutic agents for sepsis-induced AKI.

Summary: Reactive oxygen species (ROS) have significant roles in physiological and pathophysiological processes. Recent studies have shown that ROS plays a crucial role in the development and progression of osteoarthritis (OA) by mediating extracellular matrix degradation, mitochondrial dysfunction, chondrocyte apoptosis, and OA progression. Nanomaterials with ROS-scavenging ability and antioxidant effects have shown promising results in OA treatment. However, current research on nanomaterials as ROS scavengers for OA is not uniform, and the timing and potential of their clinical use remain inconsistent. This review aims to provide a reference for further studies and promote the early clinical use of nanomaterials for OA treatment.

Summary: The innate immune responses of zebrafish embryos to microbial infections include strategies based on manipulating the concentration of metals such as iron and zinc. Infection experiments with different Pseudomonas aeruginosa strains have shown that strains lacking critical components of zinc importers have reduced colonization capacity but have an advantage in the early stages of infection. The expression of genes involved in zinc transport suggests the existence of antimicrobial mechanisms based on zinc sequestration, indicating the similarity of nutritional immunity mechanisms between teleosts and higher vertebrates.

Summary: POU3F3 variants are associated with developmental delay, behavioral problems, hypotonia, and dysmorphic features. This study investigated the phenotypic and genetic characteristics of individuals with POU3F3-related disorders and identified genotype-phenotype correlations. The study included 28 individuals from 26 families carrying POU3F3 variants, and identified additional features such as gastrointestinal comorbidities, hearing loss, ophthalmological anomalies, epilepsy, sleep disturbances, and joint hypermobility. In silico structural modeling predicted that the pathogenic variants destabilize the DNA-binding region of POU3F3.

Summary: S-nitrosylation is a post-translational modification where nitric oxide (NO) binds to cysteine, forming an S-nitrosothiol (SNO) adduct. This process plays various roles in physiology and is also associated with several diseases, including cancer. In this study, we investigated the structural changes induced by S-nitrosylation in the mitochondrial chaperone TRAP1. We found that the SNO site promotes conformational changes in the nearby cysteine, facilitating disulfide bridge formation. Additionally, we analyzed thousands of S-nitrosylated proteins to identify proximal cysteines sensitive to the redox state of the SNO site, providing new insights into the biological effects of redox switches.

Summary: CVID is a heterogeneous disorder characterized by recurrent infections, low levels of serum immunoglobulins, and impaired vaccine responses. Autoimmune manifestations are common, but the mechanisms of B cell central and peripheral selection in CVID are not fully understood. This study found that central tolerance is increased in transitional B cells from CVID patients with autoimmune manifestations, while the selection pressure in germinal center on CD27bright memory B cells is decreased. Naive B cells in CVID patients also showed poor activation and induction of mismatch repair genes. These findings suggest defective peripheral selection in CVID patients with autoimmune manifestations, which may contribute to the development of autoimmunity.
