Traumatic spinal cord injury (tSCI) is a severe to the central nervous system that categorized into primary and secondary injuries. Among them, local microenvironmental imbalance in caused by includes accumulation of cytokines chemokines, reduced angiogenesis, dysregulation cellular energy metabolism, dysfunction immune cells at site injury, which severely impedes neurological recovery from (SCI). In recent years, single-cell techniques have revealed heterogeneity multiple genomic, transcriptomic, proteomic, metabolomic levels after tSCI, further deepening our understanding mechanisms underlying tSCI. However, spatial information about tSCI microenvironment, such as cell location cell-cell interactions, lost these approaches. The application multi-omics technology can solve this problem combining data obtained immunohistochemistry multiparametric analysis reveal changes microenvironment different times SCI. review, we systematically review progress study SCI, including discuss potential future therapeutic strategies.

ABSTRACT Background Vascular dementia (VaD) includes a group of brain disorders that are characterized by cerebrovascular pathology.Neuroinflammation, disruption the blood–brain barrier (BBB) permeability, white matter lesions, and neuronal loss all significant pathological manifestations VaD play key role in disease progression. Necroptosis, also known asprogrammed necrosis, is mode programmed cell death distinct from apoptosis closely associated with ischemic injury neurodegenerative diseases. Recent studies have shown necroptosis exacerbates BBB destruction, activates neuroinflammation, promotes loss, severely affects prognosis. Results Conclusions In this review, we outline roles its molecular mechanisms process VaD, particular focus on modulating neuroinflammation exacerbating permeability elaborate regulatory centrally involved cells mediated tumor necrosis factor‐α VaD. We analyze possibility specific strategy targeting would help inhibit destruction With necroptosis, study delved into impact changes prognosis to provide new treatment ideas.

Age-related long-term disability is attracting increasing attention due to the growing ageing population worldwide. However, current understanding of senescent spinal cord remains insufficient. Bulk RNA sequencing reveals that 526 genes are upregulated and 300 downregulated in cords. Pathway enrichment analysis differentially expressed shows senescence cords related phagosome function, neuroinflammation, ferroptosis, necroptosis. Prediction upstream transcription factors interactome identify Spi1 as a factor potentially plays core role Spatial transcriptomics illustrates spatial distribution transcriptomic landscape both young identifies distinct neuronal glial subtypes. The ferroptosis-associated gene Fth1 aged Flow cytometry increased accumulation free Fe2+ ROS mixed cells; however, CCK-8 assays reveal these cells resistant ferroptosis. SiRNA lentivirus experiments indicate overexpression normal reduces their sensitivity whereas knockdown increases In summary, bulk elucidate transcriptional characteristics versus cords, thus highlighting mediating ferroptosis resistance cells. Multiomics sheds light on expression signature during process-resistance via upregulation Fth1.

Highlights•RGCs demonstrate similar gene expression changes during EAE and aging•RGCs exhibit DNA damage, chromatin mark changes, nuclear lamina dystrophy in EAE•Patients with MS damage senescence-associated neurons•AAV2-OSK limits RGC death preserves visual acuity EAESummaryIn multiple sclerosis (MS), inflammation of the central nervous system results demyelination, neuroaxonal injury, cell death. However, molecular signals responsible for injury neurons are not fully characterized. Here, we profile transcriptome retinal ganglion cells (RGCs) experimental autoimmune encephalomyelitis (EAE) mice. Pathway analysis identifies a transcriptional signature reminiscent aged RGCs some senescent features, comparable present from patients MS. This is supported by immunostaining demonstrating alterations to envelope, modifications marks, accumulation damage. Transduction an Oct4-Sox2-Klf4 adeno-associated virus (AAV) rejuvenate enhances survival improves acuity. Collectively, these data reveal aging-like phenotype under pathological neuroinflammation support possibility that rejuvenation therapies or senotherapeutic agents could offer direct avenue neuroprotection neuroimmune disorders.Graphical abstract
