Inflammation, and in particular microglia activation, is regarded as a constant component of brain pathology in Parkinson's disease (PD). Microglial activation has been found in the substantia nigra (SN), one of the main brain regions affected in PD, for many years after the initiation of the disease. Although many studies point towards a deleterious role(More)
The functional role of the long-lasting inflammation found in the substantia nigra (SN) of Parkinson's disease (PD) patients and animal models is unclear. Proinflammatory cytokines such as interleukin-1beta (IL-1beta) could be involved in mediating neuronal demise. However, it is unknown whether the chronic expression of cytokines such as IL-1beta in the SN(More)
Understanding the evolution of neonatal hypoxic/ischemic is essential for novel neuroprotective approaches. We describe the neuropathology and glial/inflammatory response, from 3 hours to 100 days, after carotid occlusion and hypoxia (8% O(2), 55 minutes) to the C57/BL6 P7 mouse. Massive tissue injury and atrophy in the ipsilateral (IL) hippocampus, corpus(More)
BACKGROUND Pleiotrophin is known to promote the survival and differentiation of dopaminergic neurons in vitro and is up-regulated in the substantia nigra of Parkinson's disease patients. To establish whether pleiotrophin has a trophic effect on nigrostriatal dopaminergic neurons in vivo, we injected a recombinant adenovirus expressing pleiotrophin in the(More)
During postnatal development, microglia, the resident innate immune cells of the central nervous system are constantly monitoring the brain parenchyma, cleaning the cell debris, the synaptic contacts overproduced and also maintaining the brain homeostasis. In this context, the postnatal microglia need some control over the innate immune response. One such(More)
