Abstract Neurological diseases are the foremost cause of disability and second leading death worldwide. Owing to special microenvironment neural tissues biological characteristics cells, a considerable number neurological disorders currently incurable. In past few years, development nanoplatforms based on metal–organic frameworks (MOFs) has broadened opportunities for offering sensitive diagnosis/monitoring effective therapy neurology‐related diseases. this article, obstacles neurotherapeutics, including delayed diagnosis misdiagnosis, existence blood brain barrier (BBB), off‐target treatment, irrepressible inflammatory storm/oxidative stress, irreversible nerve cell summarized. Correspondingly, MOFs‐based diagnostic/monitoring strategies such as neuroimaging biosensors (electrochemistry, fluorometry, colorimetry, electrochemiluminescence, etc.) therapeutic higher BBB permeability, targeting specific lesion sites, attenuation neuroinflammation/oxidative stress well regeneration extensively highlighted management Finally, challenges present research from perspective clinical translation discussed, hoping facilitate interdisciplinary studies at intersections between neurotheranostics.

Journal of Nanobiotechnology, Год журнала: 2024, Номер 22(1)

Опубликована: Июль 18, 2024

Abstract Ischemic stroke is a complex, high-mortality disease with multifactorial etiology and pathogenesis. Currently, drug therapy mainly used treat ischemic in clinic, but there are still some limitations, such as limited blood-brain barrier (BBB) penetration efficiency, narrow treatment time window side effects. Recent studies have pointed out that delivery systems based on polymeric nanocarriers can effectively improve the insufficient for stroke. They provide neuronal protection by extending plasma half-life of drugs, enhancing drug’s permeability to penetrate BBB, targeting specific structures cells. In this review, we classified delivering drugs introduced their preparation methods. We also evaluated feasibility effectiveness discussed existing limitations prospects treatment. hoped review could theoretical basis future development nanomedicine Graphical

The Implications of Microglial Regulation in Neuroplasticity-Dependent Stroke Recovery

Biomolecules, Год журнала: 2023, Номер 13(3), С. 571 - 571

Stroke causes varying degrees of neurological deficits, leading to corresponding dysfunctions. There are different therapeutic principles for each stage pathological development. Neuroprotection is the main treatment in acute phase, and functional recovery becomes primary subacute chronic phases. Neuroplasticity considered basis restoration rehabilitation after stroke, including remodeling dendrites dendritic spines, axonal sprouting, myelin regeneration, synapse shaping, neurogenesis. Spatiotemporal development affects spontaneous rewiring neural circuits brain networks. Microglia resident immune cells that contribute homeostasis under physiological conditions. activated immediately phenotypic polarization changes phagocytic function crucial regulating focal global inflammation recovery. We have previously shown neuroplasticity spatiotemporally consistent with microglial activation, suggesting microglia may a profound impact on stroke be key target post-stroke rehabilitation. In this review, we explore as well functions mechanisms polarization, phagocytosis. This followed by summary microglia-targeted rehabilitative interventions influence promote

Human-induced pluripotent stem cell–derived neural stem cell exosomes improve blood–brain barrier function after intracerebral hemorrhage by activating astrocytes via PI3K/AKT/MCP-1 axis

Neural Regeneration Research, Год журнала: 2024, Номер 20(2), С. 518 - 532

Опубликована: Апрель 16, 2024

JOURNAL/nrgr/04.03/01300535-202502000-00029/figure1/v/2024-05-28T214302Z/r/image-tiff Cerebral edema caused by blood-brain barrier injury after intracerebral hemorrhage is an important factor leading to poor prognosis. Human-induced pluripotent stem cell-derived neural cell exosomes (hiPSC-NSC-Exos) have shown potential for brain repair in central nervous system diseases. In this study, we explored the impact of hiPSC-NSC-Exos on preservation and underlying mechanism. Our results indicated that intranasal delivery mitigated neurological deficits, enhanced integrity, reduced leukocyte infiltration a mouse model hemorrhage. Additionally, decreased immune infiltration, activated astrocytes, secretion inflammatory cytokines like monocyte chemoattractant protein-1, macrophage protein-1α, tumor necrosis factor-α post-intracerebral hemorrhage, thereby improving microenvironment. RNA sequencing hiPSC-NSC-Exo PI3K/AKT signaling pathway astrocytes protein-1 secretion, integrity. Treatment with inhibitor LY294002 or neutralizing agent C1142 abolished these effects. summary, our findings suggest maintains part downregulating through activation astrocytes.

Extracellular vesicles from medicated plasma of Buyang Huanwu decoction-preconditioned neural stem cells accelerate neurological recovery following ischemic stroke

Frontiers in Cell and Developmental Biology, Год журнала: 2023, Номер 11

Опубликована: Март 1, 2023

Introduction: The neurological impairment of survivors after ischemic stroke poses a serious risk to their quality life and health. Effective therapeutic options are still lacking. Neural stem cells (NSCs) promote neurogenesis via secreted extracellular vesicles (NSC-EVs), which would be potential option, but the insufficient quantity NSC-EVs in vivo restrains clinical application. Buyang Huanwu Decoction (BHD), classic traditional Chinese medicine (TCM) decoction, is promising alleviate stroke. It was speculated that BHD might recovery through NSC-EVs. Methods: medicated plasma (MP-BHD) prepared precondition NSCs isolate EVs (BHD-NSC-EVs). Middle cerebral artery occlusion (MCAO) models primary were administered evaluate effect. Next-generation sequencing performed explore mechanism. Results: BHD-NSC-EVs more significantly accelerated MCAO promoted proliferation differentiation than alone. MP-BHD enhanced largescale generation BHD-NSC-EVs, encapsulated functional miRNA may play critical roles neurogenesis. Discussion: In replacing or NSCs, preconditioned present efficient strategy for Based on efficacy TCM, preconditioning NSC-derived MP TCM herbs presents newly diseases.
