alzheimer’s disease (ad) is a neurodegenerative disease characterized by cognitive and other cns impairments which is increasing worldwide and poses a major public health problem, yet no effective treatments are found and available drugs only alleviate the symptoms temporarily. postmortem analyses on the brains of ad patients and observed lower risk of ad in nsaids users among other studies hav...

Background: Neuroinflammation, as a major outcome of microglia activation, is an important factor for progression of neurodegenerative disorders including Alzheimer's disease and Parkinson's disease. Microglial cells, as the first-line defense in the central nervous system, act as a source of neurotoxic factors such as nitric oxide (NO), a free radical which is involved in neuronal cell death. ...

The reaction between reducing sugars and protein free amines, known as the Maillar reaction results in the formation of advanced glycation endproducts (AGEs). AGE modification changes the structure of proteins to amyloid cross-beta structure. These protein structures can activate receptors known as RAGE on glial cells (microglia and astrocytes), and induce the expression of inducible nitric oxi...

Microglial cells are monocytic lineage cells that reside in the CNS and have the capacity to become activated during various pathological conditions. Although it was demonstrated that activation of microglial cells could be achieved in vitro by the engagement of CD40-CD40L interactions in combination with proinflammatory cytokines, the exact factors that mediate activation of microglial cells i...

The role of microglia during neurodegeneration remains controversial. We investigated whether microglial cells have a neurotoxic or neuroprotective function in the retina. Retinal explants from 10-day-old mice were treated in vitro with minocycline to inhibit microglial activation, with LPS to increase microglial activation, or with liposomes loaded with clodronate (Lip-Clo) to deplete microgli...

Streptococcus (S.) suis infections are the most common cause of meningitis in pigs. Moreover, S. suis is a zoonotic pathogen, which can lead to meningitis in humans, mainly in adults. We assume that glial cells may play a crucial role in host-pathogen interactions during S. suis infection of the central nervous system. Glial cells are considered to possess important functions during inflammatio...
