AI Article Synopsis

  • Unilateral intracarotid injection of contrast agents can significantly disrupt the blood-brain barrier in rats, resulting in vasogenic edema on the same side (ipsilateral hemisphere).
  • Administering ultrasound contrast agents after mild traumatic brain injury greatly increases mortality and leakage of fluids.
  • This method of direct contrast agent administration highlights edema-related issues and can worsen outcomes in studies involving neurotrauma.

Article Abstract

Unilateral intracarotid injection of contrast agents may considerably destabilize the blood-brain barrier in rats. This leads to vasogenic edema in the ipsilateral hemisphere. Mortality and extravasation increased significantly when administration of these ultrasound contrast agents was followed by mild traumatic brain injury. Direct administration to the cerebral circulation is, therefore, indicative for edema-related pathology and may amplify the consequences of experimental neurotrauma.

Role of PCBP2 in regulating nanovesicles loaded with curcumin to mitigate neuroferroptosis in neural damage caused by heat stroke.

J Nanobiotechnology

December 2024

Key Laboratory of Special Environmental Medicine of Xinjiang, General Hospital of Xinjiang Military Command, No. 359, Youhao North Road, Urumqi, Xinjiang, China.

Objective: This study aims to elucidate the mechanisms by which nanovesicles (NVs) transport curcumin(CUR) across the blood-brain barrier to treat hypothalamic neural damage induced by heat stroke by regulating the expression of poly(c)-binding protein 2 (PCBP2).

Methods: Initially, NVs were prepared from macrophages using a continuous extrusion method. Subsequently, CUR was loaded into NVs using sonication, yielding engineered cell membrane Nanovesicles loaded with curcumin (NVs-CUR), which were characterized and subjected to in vitro and in vivo tracking analysis.

Copper-coordination driven brain-targeting nanoassembly for efficient glioblastoma multiforme immunotherapy by cuproptosis-mediated tumor immune microenvironment reprogramming.

Limited drug accumulation and an immunosuppressive microenvironment are the major bottlenecks in the treatment of glioblastoma multiforme (GBM). Herein, we report a copper-coordination driven brain-targeting nanoassembly (TCe6@Cu/TP5 NPs) for site-specific delivery of therapeutic agents and efficient immunotherapy by activating the cGAS-STING pathway and downregulating the expression of PD-L1. To achieve this, the mitochondria-targeting triphenylphosphorus (TPP) was linked to photosensitizer Chlorin e6 (Ce6) to form TPP-Ce6 (TCe6), which was then self-assembled with copper ions and thymopentin (TP5) to obtain TCe6@Cu/TP5 NPs.

Omics-based analysis of mitochondrial dysfunction and BBB integrity in post-COVID-19 sequelae.

The SARS-CoV-2 virus that resulted in the COVID-19 pandemic has been implicated in a range of neurological issues, such as encephalopathy, stroke, and cognitive decline. Although the precise mechanism causing these issues is unknown, mounting evidence shows that blood-brain barrier (BBB) disruption is probable2 a major factor. The integrity of the blood-brain barrier (BBB), a highly selective barrier that divides the brain from the systemic circulation, is crucial for preserving normal brain function.

Obesity, a pandemic, worldwide afflicts almost one billion people. Obesity and ageing share several pathological pathways leading to neurological disorders. However, due to a lack of suitable animal models, the long-term effects of obesity on age-related disorders- cognitive impairment and dementia have not yet been thoroughly investigated.
