OBJECTIVE To investigate CSF biomarkers of neuroinflammation and neurodegeneration in Huntington disease (HD) gene-expansion carriers compared to controls and to investigate these biomarkers in association with clinical HD rating scales and disease burden score. METHODS We collected CSF from 32 premanifest and 48 manifest HD gene-expansion carriers and 24 gene-expansion negative at-risk contr...

neuroinflammation is inflammation of the nervous tissue. it be initiated in response to infection, toxic metabolites, auto immunity, traumatic brain injury and variety of causes. exercise is a promising mechanism of prevention and treatment for disease characterized by neuroinflammation. the benefits of exercise and physical activity (pa) are well known and have effects on function of the centr...

Neuroinflammation is an important feature in the pathogenesis and progression of neurodegenerative diseases such as Alzheimer´s disease (AD), Parkinson´s disease (PD), frontotemporal dementia and amyotrophic lateral sclerosis. Based on current knowledge in the field, suggesting that targeting peripheral inflammation could be a promising additional treatment/prevention approach for neurodegenera...

Amyotrophic lateral sclerosis (ALS) is a progressive neurodegenerative disease that affects upper motor neurons (MNs) comprising the corticospinal tract and lower MNs arising from the brain stem nuclei and ventral roots of the spinal cord, leading to fatal paralysis. Currently, there are no effective therapies for ALS. Increasing evidence indicates that neuroinflammation plays an important role...

Increasing evidence suggests that the pathogenesis of neurodegenerative diseases including amyotrophic lateral sclerosis (ALS) is not restricted to the neurons but attributed to the abnormal interactions of neurons and surrounding glial and lymphoid cells. These findings led to the concept of non-cell autonomous neurodegeneration. Neuroinflammation, which is mediated by activated glial cells an...

Almost 47 million people suffer from dementia worldwide, with an estimated new case diagnosed every 3.2 seconds. Alzheimer's disease (AD) accounts for approximately 60%-80% of all dementia cases. Given this evidence, it is clear dementia represents one of the greatest global public health challenges. Currently used drugs alleviate the symptoms of AD but do not treat the underlying causes of dem...

We studied concomitantly the level of neuroinflammation and Aβ load in the APPswePS1dE9 transgenic mouse model of Alzheimer’s disease using PET imaging. The TSPO tracer [F]DPA-714 was used to measure neuroinflammation and [F]AV-45 for Aβ load in mice at 6, 9, 12, 15 and 19 months of age. At 19 months, we also analysed the neuroinflammatory and neuroanatomical status of mice brains. Imaging expe...

Osteopontin also known as bone sialoprotein (BSP). Osteopontin role as a linking protein. it is an extracellular structural protein and therefore an organic component of bone. Osteoprontin (OPN) binds to several integrin receptors containing α4β1, α9β1, and α9β4 expressed by leukocytes. These receptors have been well-stable to function in cell adhesion, migratio...

Neuroinflammation is a major component of several neurodegenerative disorders such as Alzheimer's disease, HIV-associated dementia, Multiple sclerosis and Parkinson's disease. Although the primary pathology underlying each of these diseases is vastly different, neuroinflammation, consisting of chronic activation of brain macrophages, is a significant factor that contributes to neuronal damage i...

One of the most common postoperative complications is Postoperative cognitive dysfunction (POCD), and it’s usually a geriatric’s disease. Although many studies have done, the exact molecular mechanisms of POCD is still largely unknown; nevertheless, neuroinflammation has been increasingly denoted as one of the core mechanisms for the pathogenesis of POCD. As a hypothesize, surgery-i...
