Abstract Traumatic brain injury (TBI) is one of the leading causes disability and mortality, which was classified as low-altitude TBI high-altitude TBI. A large amount literature shows that associated with more severe neurological impairments higher mortality rates compared to TBI, due special environment hypoxia. However, role hypoxia in pathogenesis remains unclear. In order deeply investigate this scientific issue, we constructed a hypoxic model at different altitudes used animal behavioral assessments (Modified severity score, rotarod test, elevated plus maze test) well histopathological analyses (brain gross specimens, water content, Evans blue inducible factor-1α, Hematoxylin-Eosin staining ROS detection) reveal its underlying principles characteristics. We found altitude, TBI-induced deficits were changes significant. Single-nuclear RNA sequencing subsequently employed further differential gene expression profiles significant increase ferroptosis astrocytes cases those Analyzing transcription factors depth, Bach1 plays crucial regulating key molecules induce following Down-regulation can effectively alleviate mice. conclusion, may significantly enhance aggravate by up-regulating expression. Our study provides theoretical foundation for understanding mechanism targeted intervention therapy.

Various forms of neuronal death contribute to neurological injury after traumatic brain (TBI), leading irreversible deficits. Among these, ferroptosis is a form regulated cell characterized by the accumulation iron-dependent lipid hydroperoxides and induced incorporation polyunsaturated fatty acids (PUFAs) into cellular membranes. Adiponectin (APN), cytokine secreted adipocytes, have showed neuroprotective effects binding adiponectin receptors (AdipoRs), which are widely expressed in central nervous system. However, role TBI APN-AdipoRs signaling remains unexplored. Our clinical analysis revealed significant correlation between serum levels APN 6-month outcomes patients. Subsequent studies confirmed that TBI-induced was more pronounced knockout mice compared wild-type mice, while additional receptor agonist (AdipoRon) treatment significantly mitigated ferroptosis. Furthermore, AdipoR1 knockdown diminished protective AdipoRon against erastin-induced primary neurons. Correspondingly, neuron-specific conditional (AdipoR1CKO) neurons were susceptible TBI, increased edema lesion volume, exacerbated Mechanically, activation APN-AdipoR1 promoted adenosine monophosphate activated protein kinase (AMPK) -mediated phosphorylation acetyl-CoA carboxylase-1 (ACC1), thus suppressed PUFAs biosynthesis, determines theferroptosissensitivity Taken together, these findings provided compelling evidence for inhibiting AMPK-ACC1.

Abstract Neuronal cell death is a causative process in traumatic brain injury (TBI)-induced structural and functional impairment of the central nervous system. However, upstream trigger TBI-induced neuronal loss underlying molecular pathways remain unclear. Zipper-interacting protein kinase (ZIPK) has been shown to be upregulated Alzheimer’s disease ischemic stroke play role cellular apoptosis, while its pathological significance TBI not reported. Herein, we discovered for first time that ZIPK expression was markedly elevated neurons after caused massive apoptosis peri-contusional regions. Zipk haploinsufficiency antagonized reversed several typical neuropathological changes induced by TBI. Mechanistically, found affected viability modulating effector domain-containing DNA binding (DEDD) caspase-3 pathway. Specifically, could bind phosphorylate DEDD at S9 residue, thus enhancing stability DEDD, leading activation caspase-3-mediated apoptotic cascade neurons. The rescue downregulation effectively alleviated behavioral deficits preserving motor cognitive abilities vivo, supporting decisive dysregulation TBI-associated dysfunctions survival. Furthermore, pharmacological suppression activity specific inhibitor prior protected from injury-induced degeneration vitro vivo preventing upregulation activation. In conclusion, our data reveal essential contribution through DEDD/caspase-3 cascade, suggest potential targeting as an effective strategy treating TBI-related neuropathologies.

Iron is essential in various physiological processes, but its accumulation leads to oxidative stress and cell damage, thus iron homeostasis has be tightly regulated. Ferroptosis an iron-dependent non-apoptotic regulated death characterized by overload ROS accumulation. Mitochondria are organelles playing a crucial role metabolism involved ferroptosis. MitoNEET, protein of mitochondrial outer membrane, key element this process. Ferroptosis, altering levels several metabolically active organs, linked non-communicable diseases. For example, the liver hepatic fibrosis cirrhosis, accelerating NAFLD progression, muscle cells contributes damage leading sarcopenia, brain associated neurodegeneration. The aim review investigate intricate balance regulation focusing on mitochondria stress, analyzing ferroptosis implications health disease.

Microplastics biological toxicity, environmental persistence and chemicals have been paid widespread attention. exposed to chicken spleen injury of the specific mechanism is unclear. Thus, we randomly assigned chickens 4 groups: C (normal diet), L-MPs (1 mg/L), M-MPs (10 H-MPs (100 assessed damage after 42 d exposure. Morphologically, boundary between red white pulp was blurred, along with expansion pulp. It further speculated that microplastics induced mitochondrial dynamic homeostasis (Drp1 upgraded, Mfn1, Mfn2, OPA1 reduced), provoked apoptotic pathway (Bcl-2/Bax decreased, cytc, caspase3, caspase9 raised), resulting in redox imbalance lipid peroxide accumulation (MDA increased, CAT, GSH, T-AOC plummeted), stimulated ferroptosis (FTH1, GPX4, SLC7A11 decreased). Here explored impact polystyrene on spleen, as well programmed death (apoptosis ferroptosis) involved, regulative role mitochondria this process. This could be significant importance bridging gap laboratory research microplastics-induced chicken.
