The pathophysiology of glaucoma is complex, multifactorial and not completely understood. Elevated intraocular pressure (IOP) and/or impaired retinal blood flow may cause initial optic nerve damage. In addition, age-related oxidative stress in the retina concurrently with chronic mechanical vascular crucial for initiation neurodegeneration. Oxidative closely related to cell senescence, mitochondrial dysfunction, excitotoxicity, neuroinflammation, which are involved progression. Accumulating evidence from animal models human ocular samples suggests a dysfunction para-inflammation ganglion layer head. Moreover, quite similar mechanisms anterior chamber could explain trabecular meshwork elevated IOP primary open-angle glaucoma.

Microglia are the brain’s immunocompetent macrophages with a unique feature that allows surveillance of surrounding microenvironment and subsequent reactions to tissue damage, infection, or homeostatic perturbations. Thereby, microglia’s striking morphological plasticity is one their prominent characteristics categorization microglial cell function based on morphology well established. Frequently, automated classification phenotypes performed by using quantitative parameters. As this process typically limited few especially manually chosen criteria, relevant selection bias may compromise resulting classifications. In our study, we describe novel method evaluation convolutional neuronal network basis selected cells in addition classical We focused four morphologies, ramified, rod-like, activated amoeboid microglia within murine hippocampus cortex.

Neuroprotection is a proactive approach to safeguarding the nervous system, including brain, spinal cord, and peripheral nerves, by preventing or limiting damage nerve cells other components. It primarily defends central system against injury from acute progressive neurodegenerative disorders. Oxidative stress, an imbalance between body's natural defense mechanisms generation of reactive oxygen species, crucial in developing neurological Due its high metabolic rate consumption, brain particularly vulnerable oxidative stress. Excessive ROS damages essential biomolecules, leading cellular malfunction neurodegeneration.

Abstract Increasing life expectancy has led to an aging population, which consequently increased the prevalence of dementia. Alzheimer's disease (AD), most common form dementia worldwide, is estimated make up 50–80% all cases. AD cases are expected reach 131 million by 2050, and this increasing will critically burden economies health systems in next decades.

Intercellular communication in the central nervous system (CNS) is essential for brain growth, development, and homeostasis maintenance and, when dysfunctional, involved occurrence development of neurodegenerative diseases. Increasing evidence indicates that extracellular vesicles, especially exosomes, are critical mediators intercellular signal transduction. Under physiological pathological conditions, neural cells secret exosomes with influence many factors. These can carry specific proteins, lipids, nucleic acids, other bioactive substances to recipient regulate their function. Depending on CNS environment, as well origin or status parental cells, mediate a variety different effects, including synaptic plasticity, nutritional metabolic support, nerve regeneration, inflammatory response, anti-stress effect, cellular waste disposal, propagation toxic components, playing an important role health This review will discuss possible roles both physiologic conditions.

Microglia and astrocytes maintain tissue homeostasis in the nervous system. Both microglia have pro-inflammatory phenotype anti-inflammatory phenotype. Activated activated can contribute to several neurological diseases. Long non-coding RNAs (lncRNAs) circular (circRNAs), two groups of (ncRNAs), function as competing endogenous (ceRNAs) impair microRNA (miRNA) inhibition on targeted messenger (mRNAs). LncRNAs circRNAs are involved various disorders. In this review, we summarized that lncRNAs participate dysfunction, astrocyte neuron damage, inflammation. Thereby, positively or negatively regulate diseases, including spinal cord injury (SCI), traumatic brain (TBI), ischemia-reperfusion (IRI), stroke, neuropathic pain, epilepsy, Parkinson’s disease (PD), multiple sclerosis (MS), Alzheimer’s (AD). Besides, also found a lncRNA/circRNA-miRNA-mRNA regulatory network mediated Through hope cast light mechanisms diseases provide new insights for treatment.
