Alzheimer's disease (AD) is one of the most prevalent neurodegenerative diseases and a major contributor to dementia. Although cause this condition has been identified long ago as aberrant aggregations amyloid tau proteins, effective therapies for it remain elusive. The complexities drug development AD treatment are often compounded by impermeable blood-brain barrier low-yield brain delivery. In addition, use high concentrations overcome challenge may entail side effects. To address these challenges enhance precision delivery into regions affected aggregation, we proposed transferrin-conjugated nanoparticle-based system. melittin-loaded L-arginine-coated iron oxide nanoparticles (Tf-MeLioNs) developed in study successfully mitigated melittin-induced cytotoxicity hemolysis cell culture 5XFAD mouse brain, Tf-MeLioNs remarkably reduced plaque accumulation, particularly hippocampus. This suggested Tf-LioNs potential platform candidate therapeutic targeting plaques AD. These findings provide foundation further exploration advancement therapeutics.

Alzheimer's disease (AD) is a neurogenerative and remains no effective method for stopping its progress. Ferroptosis adaptive immunity have been proven to contribute AD pathogenesis. Salidroside exhibits neuroprotective immunomodulatory effects. However, the underlying mechanisms linking salidroside, ferroptosis, in remain uncertain.The objective of this study explore effects potential molecular salidroside against neuronal ferroptosis CD8+ T cell infiltration senescence-accelerated mouse prone 8 (SAMP8) mice.SAMP8 mice were employed as an model treated with 12 weeks. Behavioral tests, immunohistochemistry, HE Nissl staining, immunofluorescence, transmission electron microscopy, quantitative proteomics, bioinformatic analysis, flow cytometry, iron western blotting, docking performed.Treatment dose-dependently attenuated cognitive impairment, reduced accumulation Aβ plaques restored damage. also suppressed CD8+T cells, oxidative stress, inflammatory cytokines, improved mitochondrial metabolism, lipid redox SAMP8 brain. The administration decreased deposition, TFR1, ACSL4 protein expression, upregulated SLC7A11, GPX4 promoted Nrf2/GPX4 axis activation.In conclusion, cells are involved process impairment mice. alleviates inhibits ferroptosis. may involve activation reduction infiltration.

Iron is an essential element for the development and functionality of brain, anomalies in its distribution concentration brain tissue have been found to be associated with most frequent neurodegenerative diseases. When magnetic resonance techniques allowed iron quantification vivo, it was confirmed that alteration homeostasis a common feature many However, whether main actor process, or consequence degenerative process still open question. Because different iron-related pathogenic mechanisms are specific distinctive diseases, identifying molecular various pathologies could represent way clarify this complex topic. Indeed, both overload deficiency profound consequences on cellular functioning, contribute neuronal death processes manners, such as promoting oxidative damage, loss membrane integrity, proteostasis, mitochondrial dysfunction. In review, attempt elucidate dyshomeostasis health, we summarize pathological couple death.

Central neurological disorders are significant contributors to morbidity, mortality, and long-term disability globally in modern society. These encompass neurodegenerative diseases, ischemic brain traumatic injury, epilepsy, depression, more. The involved pathogenesis is notably intricate diverse. Ferroptosis neuroinflammation play pivotal roles elucidating the causes of cognitive impairment stemming from these diseases. Given concurrent occurrence ferroptosis due metabolic shifts such as iron ROS, well their critical central nervous disorders, investigation into co-regulatory mechanism has emerged a prominent area research. This paper delves mechanisms along with interrelationship. It specifically emphasizes core molecules within shared pathways governing neuroinflammation, including SIRT1, Nrf2, NF-κB, Cox-2, iNOS/NO·, how different immune cells structures contribute dysfunction through mechanisms. Researchers’ findings suggest that mutually promote each other may represent key factors progression disorders.

Damage or loss of brain cells and impaired neurochemistry, neurogenesis, synaptic nonsynaptic plasticity the lead to dementia in neurodegenerative diseases, such as Alzheimer's disease (AD). Injury synapses neurons accumulation extracellular amyloid plaques intracellular neurofibrillary tangles are considered main morphological neuropathological features AD. Age, genetic epigenetic factors, environmental stressors, lifestyle contribute risk AD onset progression. These factors associated with structural functional changes brain, leading cognitive decline. Biomarkers reflect cause specific function, especially pathways neurotransmission, neuroinflammation, bioenergetics, apoptosis, oxidative nitrosative stress. Even initial stages, is Aβ neurotoxicity, mitochondrial dysfunction, tau neurotoxicity. The integrative amyloid-tau-mitochondrial hypothesis assumes that primary neurotoxicity oligomers oligomers, their mutual synergy. For development new efficient drugs, targeting elimination potentiation effects, unwanted protein interactions biomarkers (mainly dysfunction) early stage seems promising.

Microglia and astrocytes are regarded as active participants in the central nervous system under various neuropathological conditions, including Alzheimer's disease (AD). Both microglia astrocyte activation have been reported to occur with a spatially temporarily distinct pattern. Acting double-edged sword, glia-mediated neuroinflammation may be both detrimental beneficial brain. In variety of neuropathologies, activated before astrocytes, which facilitates activation. Yet reactive can also prevent adjacent addition helping them become activated. Studies describe changes genetic profile well cellular molecular responses these two types glial cells that contribute dysfunctional immune crosstalk AD. this paper, we construct current knowledge microglia-astrocyte communication, highlighting multifaceted functions their role A thorough comprehension communication could hasten creation novel AD treatment approaches.

Nevertheless, many studies reported neurotoxicity among pediatric aged populations. This effect is usually manifested as cognitive impairment such perioperative neurocognitive disorders. The wide application of during makes safety a major health concern. Evidence indicates that iron dyshomeostasis ferroptosis may establish role isoflurane. However, mechanisms sevoflurane- isoflurane-induced neuronal injury were not fully understood, which poses barrier to treatment its neurotoxicity.
