Abstract:
Microglia influence pathological progression in neurological diseases, reacting to insults by expressing multiple morphofunctional phenotypes. However, the complete morphological spectrum of reactive microglia, as revealed by three-dimensional microscopic reconstruction, has not been detailed in virus limbic encephalitis. Here, using an anatomical series of brain sections, we expanded on an earlier Piry arbovirus encephalitis study to include CA1/CA2 and assessed the morphological response of homeostatic and reactive microglia at eight days post-infection.

Abstract:
Peripheral inflammatory stimuli increase proinflammatory cytokines in the bloodstream and central nervous system and activate microglial cells. Here we tested the hypothesis that contrasting environments mimicking sedentary and active lives would be associated with differential microglial morphological responses, inflammatory cytokines concentration, and virus load in the peripheral blood. For this, mice were maintained either in standard (standard environment) or enriched cages (enriched environment) and then subjected to a single (DENV1) serotype infection.

Abstract:
Abstract Background: Patients with sickle cell disease (SCD) experience acute pain episodes in early childhood; over 50% of adult SCD patients go on to develop chronic pain. In animal models, microglia, derived from hematopoietic stem cells, play an important role in the transition from acute to chronic pain; in patients with chronic pain microglia are often activated with minimal stimuli, releasing TNF-alpha and stimulating neurons. Research involving microglia has been stymied by difficulty in obtaining and culturing microglia, particularly from humans. We therefore propose to culture microg

AbstractCocaine is a highly addictive stimulant and a well-known drug, with multiple effects on physiology. Cocaine can have direct effects on all cell types in the brain, including microglia. Microglia can be activated by other conditions, such as infection, inflammation, or injury. However, how cocaine regulates microglia and the influence of cocaine on microglial-derived exosomes remains unknown. Exosomes are nanovesicles that are responsible for intercellular communications, signaling, and trafficking necessary cargo for cell homeostasis. In this study, we hypothesized that cocaine affects

The reactions of a microglial cell population to exposure to interferon-gamma (IFN-γ) were studied in primary cultures of mixed glial cells from the brains of newborn rats. One week after seeding, the cells were exposed to 200U/ml of IFN-γ for 24 and 48 hours. After exposure to IFN-γ for 48 hours, a third of the cultures were exposed to phorbol myristate acetate (PMA) for 90 minutes. Transformation of the microglial cells in response to this treatment was observed by using a light microscope.

Abstract:
Central to the progression of cerebral toxoplasmosis is the interaction of Toxoplasma gondii with the blood-brain barrier (BBB) endothelial cells. In the present work, we tested the hypothesis that inhibition of Wnt pathway signalling by the monovalent ionophore monensin reduces the growth of T. gondii infecting human brain microvascular endothelial cells (hBMECs) or microglial cells. The anti-parasitic effect of monensin (a Wnt signalling inhibitor) on the in vitro growth of T. gondii tachyzoites was investigated using two methods (Sulforhodamine B staining and microscopic parasite counting).

Several studies on small animals have shown that MRI enhanced with nanoparticles of iron oxide (USPIO) is able to detect the neuroinflammation. However, to our knowledge, no team had yet investigated the potential of this approach for monitoring an anti-inflammatory treatment. In this context, we have demonstrated the feasibility of this approach to monitor the effects of minocycline after cerebral ischemia in mice. MRI is a very sensitive technique for the detection of iron, but the precise location of USPIO as well as their quantification is difficult. We therefore propsed to complete the MR
