Effect of Inflammation on the Process of Stroke Rehabilitation and Poststroke Depression
Conclusions Stroke comprises ischemic stroke and ICH. The immuno-inflammatory process is involved in neural plasticity following events such as a hemorrhage or ischemic stroke. After ischemia, astrocytes, microglia, and MDMs play important roles during rehabilitation with the modulation of cytokines or chemokines, such as TNF-α and IL-1. Moreover, MiRNAs are also important posttranscriptional regulators in these glial mitochondrial responses to cerebral ischemia. ICH involves processes similar and different to those seen in ischemia, including neuronal injury, astrocytic and microglial/macrophage activation, and n...

A Hallmark Clinical Study of Cord Blood Therapy in Adults with Ischemic Stroke.
Abstract The therapeutic application of human umbilical cord blood cells has been an area of great interest for at least the last 25 years. Currently, cord blood cells are approved for reconstitution of the bone marrow following myeloablation in both young and old patients with myeloid malignancies and other blood cancers. Translational studies investigating alternative uses of cord blood have also shown that these cells not only stimulate neurogenesis in the aged brain but are also potentially therapeutic in the treatment of adult neurodegenerative disorders including amyotrophic lateral sclerosis, Alzheimer's di...

Effects of Neurotrophic Factors in Glial Cells in the Central Nervous System: Expression and Properties in Neurodegeneration and Injury
Conclusion and Future Aspects This review summarizes available NTF expression data, compiles existing evidence on the effects of glial NTF signaling in healthy conditions and in disease models (Figure 1), and highlights the importance of this topic for future studies. The relationship between NTFs and glia is crucial for both the developing and adult brain. While some of these factors, such as NT-3 and CNTF, have highly potent effects on gliogenesis, others like BDNF and GDNF, are important for glia-mediated synapse formation. Neurotrophic factors play significant roles during neurodegenerative disorders. In many cases, ...

Isotropic Generalized Diffusion Tensor MRI
Scientists at the Eunice Kennedy Shriver National Institute for Child Health and Human Development (NICHD) have developed a method implemented as pulse sequences and software to be used with magnetic resonance imaging (MRI) scanners and systems. This technology is available for licensing and commercial development. The method allows for measuring and mapping features of the bulk or average apparent diffusion coefficient (ADC) of water in tissue – aiding in stroke diagnosis and cancer therapy assessment. The pulse sequences and software enable MRI scanners to yield diffusion weighted images (DWI) that are orientationally ...

Membrane‐type 1 metalloproteinase is upregulated in microglia/brain macrophages in neurodegenerative and neuroinflammatory diseases
We previously reported that glioma cells induce the expression of membrane‐type 1 metalloproteinase (MT1‐MMP or MMP‐14) in tumor‐associated microglia/macrophages and promote tumor growth, whereas MMP‐14 expression in microglia under physiological conditions is very low. Here, we show that the increase in MMP‐14 expression is also found in microglia/macrophages associated with neurodegenerative and neuroinflammatory pathologies in mouse models as well as in human biopsies or post‐mortem tissue. We found that microglial/macrophage MMP‐14 expression was upregulated in Alzheimer's disease tissue, in active lesi...

The pathophysiological role of astrocytic endothelin-1
Publication date: Available online 28 April 2016 Source:Progress in Neurobiology Author(s): Stéphanie Hostenbach, Miguel D’haeseleer, Ron Kooijman, Jacques De Keyser In the normal central nervous system, endothelin-1 (ET-1) is found in some types of neurons, epithelial cells of the choroid plexus, and endothelial cells of microvessels, but it is usually not detectable in glial cells. However, in different pathological conditions, astrocytes adapting a reactive phenotype express high levels of ET-1 and its receptors, mainly the ETB receptor. ET-1 released by reactive astrocytes appears mainly to have neurodeleterio...

Neuro faces of beneficial T cells: essential in brain, impaired in aging and neurological diseases, and activated functionally by neurotransmitters and neuropeptides
Neural Regen Res. 2023 Jun;18(6):1165-1178. doi: 10.4103/1673-5374.357903.ABSTRACTT cells are essential for a healthy life, performing continuously: immune surveillance, recognition, protection, activation, suppression, assistance, eradication, secretion, adhesion, migration, homing, communications, and additional tasks. This paper describes five aspects of normal beneficial T cells in the healthy or diseased brain. First, normal beneficial T cells are essential for normal healthy brain functions: cognition, spatial learning, memory, adult neurogenesis, and neuroprotection. T cells decrease secondary neuronal degeneration,...

Inhaled Stem Cells Might Replace Lost Neurons
Many diseases of the central nervous system involve the death of neurons--so, theoretically, the replacement of dead cells should improve symptoms of degenerative disorders such as Parkinson's, Huntington's, amyotrophic lateral sclerosis (ALS) and Alzheimer's, as well as stroke and brain tumors. Stem cell therapy may do just that even though evidence of its effectiveness is mixed. [More]

The Man Who Grew Eyes
The train line from mainland Kobe is a marvel of urban transportation. Opened in 1981, Japan’s first driverless, fully automated train pulls out of Sannomiya station, guided smoothly along elevated tracks that stand precariously over the bustling city streets below, across the bay to the Port Island. The island, and much of the city, was razed to the ground in the Great Hanshin Earthquake of 1995 – which killed more than 5,000 people and destroyed more than 100,000 of Kobe’s buildings – and built anew in subsequent years. As the train proceeds, the landscape fills with skyscrapers. The Rokkō mounta...

Multiple faces of protein interacting with C kinase 1 (PICK1): structure, function, and diseases
Publication date: Available online 9 March 2016 Source:Neurochemistry International Author(s): Yun-Hong Li, Nan Zhang, Ya-Nan Wang, Ying Shen, Yin Wang Protein interacting with C-kinase 1 (PICK1) has received considerable attention because it is the only protein that contains both PSD-95/DlgA/ZO-1 (PDZ) domain and Bin-Amphiphysin-Rvs (BAR) domain. Through PDZ and BAR domains, PICK1 binds to a large number of membrane proteins and lipid molecules, and is thereby of multiple functions. PICK1 is widely expressed in various tissues, particularly abundant in the brain and testis. In the central nervous system (CNS), PICK...

Proteostasis impairment in ALS.
Abstract In physiological conditions the maintenance of the cellular proteome is a prerequisite for optimal cell functioning and cell survival. Additionally, cells need to constantly sense and adapt to their changing environment and associated stressors. Cells achieve this via a set of molecular chaperones, protein clearance pathways as well as stress-associated signaling networks which work together to prevent protein misfolding, its aggregation and accumulation in subcellular compartments. These processes together form the proteostasis network which helps in maintaining cellular proteostasis. Imbalance or impair...

Emerging Roles of Protein Kinases in Microglia-mediated Neuroinflammation.
Abstract Neuroinflammation is mediated by resident central nervous system glia, neurons, peripherally derived immune cells, blood-brain barrier, and inflammatory mediators secreted from these cells. Neuroinflammation has been implicated in stroke and neurodegenerative diseases such as Alzheimer's disease, Parkinson's disease, multiple sclerosis, and amyotrophic lateral sclerosis. Protein kinases have been one of the most exploited therapeutic targets in the current pharmacological research, especially in studies on cancer and inflammation. To date, 32 small-molecule protein kinase inhibitors have been approved by ...

Palliative Care in Neurology
Palliative medicine is a specialty that focuses on improving the quality of life for patients with serious or advanced medical conditions, and it is appropriate at any stage of disease, including at the time of diagnosis. Neurologic conditions tend to have high symptom burdens, variable disease courses, and poor prognoses that affect not only patients but also their families and caregivers. Patients with a variety of neurologic conditions such as Parkinson disease, dementia, amyotrophic lateral sclerosis, brain tumors, stroke, and acute neurologic illnesses have substantial unmet needs that can be addressed through a combi...
