Abstract

Inflammation in central nervous system (CNS) plays a vital role in neurodegenerative diseases such as Alzheimer's disease (AD), Parkinson's disease (PD), Lewy body dementia (DLB), HIV-related dementia and traumatic brain injury. Icariside II (ICS II), an active flavonoid compound derived from a Chinese herbal medicine Epimedium brevicornum Maxim, has been shown to possess a neuroprotective effect on AD model. However, whether ICS II has a directly protective effect on acute neuroinflammation remains still unclear. Therefore, the current study was designed to investigate the possible protective effect of ICS II on acute neuroinflammation induced by intracerebroventricular (ICV) injection of lipopolysaccharide (LPS), and further to explore its possible mechanism. After ICS II was prophylactically administered for 7 days before LPS injection, the rats were randomly divided into five groups as follows: sham group (n = 9), sham + ICS II-H (10 mg/kg) (n = 9), LPS (n = 14), LPS + ICS II-L (3 mg/kg) (n = 14), LPS + ICS II-H (10 mg/kg) (n = 14) groups, respectively. As expected, LPS injection exhibited neuronal morphological damage, and ionized calcium binding adapter molecule 1 (IBA-1) of microglia and glial fibrillary acidic protein (...Continue Reading

Astrocytes & Huntington’s Disease

Astrocytes are abundant within the central nervous system and their dysfunction has been thought to be an important contributor to some neurodegenerative diseases, in particular Huntington’s disease. Damage to these cells may make neurons more susceptible to degeneration. Here is the latest research on astrocytes and Huntington’s disease.

Astrocytes and Neurodegeneration

Astrocytes are important for the health and function of the central nervous system. When these cells stop functioning properly, either through gain of function or loss of homeostatic controls, neurodegenerative diseases can occur. Here is the latest research on astrocytes and neurodegeneration.

Astrocytes in Parkinson Disease

Parkinson's disease (PD) is a neurodegenerative disorder caused by the progressive loss of dopaminergic neurons. Some PD-genes may be associated with astrocyte dysfunction. Discover the latest research on astrocytes in Parkinson's disease here.

Alzheimer's Disease: Genes&Microglia

Genes and microglia are associated with the risk of developing and the progression of conditions such as Alzheimer's Disease (AD). Here are the latest discoveries pertaining to this disease.

Astrocytes

Astrocytes are glial cells that support the blood-brain barrier, facilitate neurotransmission, provide nutrients to neurons, and help repair damaged nervous tissues. Here is the latest research.

Brain Injury & Trauma

brain injury after impact to the head is due to both immediate mechanical effects and delayed responses of neural tissues.
