Rutin improves glutamate uptake and inhibits glutamate excitotoxicity in rat brain slices.

Rutin is an important flavonoid consumed in the daily diet. It is also known as vitamin P and has been extensively investigated due to its pharmacological properties. On the other hand, neuronal death induced by glutamate excitotoxicity is present in several diseases including neurodegenerative diseases.

Anti-inflammatory activity of Jatropha curcas L. in brain glial cells primary cultures.

Ethnopharmacological Relevance: Jatropha curcas L. (Euphorbiaceae), a medicinal plant known in Brazil as "Pinhão Manso", is highly adaptable, being cultivated in different tropical and subtropical regions of the world. Antimicrobial, antioxidant and antiinflammatory activities have been attributed to different parts of the plant.

Neuroimmunomodulatory and Neuroprotective Effects of the Flavonoid Apigenin in Models of Neuroinflammation Associated With Alzheimer's Disease.

Neurodegenerative disorders (ND) are characterized by the progressive and irreversible loss of neurons. Alzheimer's Disease (AD) is the most incident age-related ND, in which the presence of a chronic inflammatory compound seems to be related to its pathogenesis. Different stimuli in the central nervous system (CNS) can induce activation, proliferation, and changes in phenotype and glial function, which can be modulated by anti-inflammatory agents.

Agathisflavone modulates astrocytic responses and increases the population of neurons in an in vitro model of traumatic brain injury.

Traumatic brain injury (TBI) is a critical health problem worldwide, with a high incidence rate and potentially severe long-term consequences. Depending on the level of mechanical stress, astrocytes react with complex morphological and functional changes known as reactive astrogliosis. In cases of severe tissue injury, astrocytes proliferate in the area immediately adjacent to the lesion to form the glial scar, which is a major barrier to neuronal regeneration in the central nervous system.

Phytoestrogen Agathisflavone Ameliorates Neuroinflammation-Induced by LPS and IL-1β and Protects Neurons in Cocultures of Glia/Neurons.

Inflammation and oxidative stress are common aspects of most neurodegenerative diseases in the central nervous system. In this context, microglia and astrocytes are central to mediating the balance between neuroprotective and neurodestructive mechanisms. Flavonoids have potent anti-inflammatory and antioxidant properties.

The flavonoid rutin and its aglycone quercetin modulate the microglia inflammatory profile improving antiglioma activity.

Microglia cells are the immune effector in the Central Nervous System (CNS). However, studies have showed that they contribute more to glioma progression than to its elimination. Rutin and its aglycone quercetin are flavonoids present in many fruits as well as plants and have been demonstrated to bear anti-inflammatory, antioxidant and antitumor properties also to human glioblastoma cell lines.

Agathisflavone, a flavonoid derived from Poincianella pyramidalis (Tul.), enhances neuronal population and protects against glutamate excitotoxicity.

Flavonoids are bioactive compounds that are known to be neuroprotective against glutamate-mediated excitotoxicity, one of the major causes of neurodegeneration. The mechanisms underlying these effects are unresolved, but recent evidence indicates flavonoids may modulate estrogen signaling, which can delay the onset and ameliorate the severity of neurodegenerative disorders. Furthermore, the roles played by glial cells in the neuroprotective effects of flavonoids are poorly understood.

The flavonoid rutin modulates microglial/macrophage activation to a CD150/CD206 M2 phenotype.

Rutin is a glycosylated flavonoid present in many fruits and plants that has been demonstrated to have anti-inflammatory and antioxidant properties. However, little is known about the mechanisms underlying microglial activation and its effects on the regulation of cytokines and chemokines associated with inflammatory responses in the central nervous system. In this study we examined the effect of rutin on resting or lipopolysaccharide (LPS)-stimulated microglia and characterized their modulation to an activated M1 phenotype or an alternatively activated M2 phenotype.
