In degenerative disorders of the central nervous system (CNS), transplantation of neural multipotent (stem) precursor cells (NPCs) is aimed at replacing damaged neural cells. Here we show that in CNS inflammation, NPCs are able to promote neuroprotection by maintaining undifferentiated features and exerting unexpected immune-like functions. In a mouse model(More)
Duchenne muscular dystrophy is a lethal recessive disease characterized by widespread muscle damage throughout the body. This increases the difficulty of cell or gene therapy based on direct injections into muscles. One way to circumvent this obstacle would be to use circulating cells capable of homing to the sites of lesions. Here, we showed that stem cell(More)
Efficient delivery of cells to target tissues is a major problem in cell therapy. We report that enhancing delivery of mesoangioblasts leads to a complete reconstitution of downstream skeletal muscles in a mouse model of severe muscular dystrophy (alpha-sarcoglycan ko). Mesoangioblasts, vessel-associated stem cells, were exposed to several cytokines, among(More)
Migration of lymphocytes from the blood into the brain is a critical event in the pathogenesis of experimental autoimmune encephalomyelitis. Lymphocyte adhesion to brain endothelium is the first step in lymphocyte entry into the central nervous system, leading subsequently to myelin damage and paralysis. In this paper we show that the tyrosine kinase(More)
Epilepsy has been considered mainly a neuronal disease, without much attention to non-neuronal cells. In recent years growing evidence suggest that astrocytes, microglia, blood leukocytes and blood-brain barrier breakdown are involved in the pathogenesis of epilepsy. In particular, leukocyte-endothelium interactions and eventually subsequent leukocyte(More)
Mesenchymal stem cells (MSCs) represent a promising therapeutic approach in nerve tissue engineering. To date, the local implantation of MSC in injured nerves has been the only route of administration used. In case of multiple sites of injury, the systemic administration of cells capable of reaching damaged nerves would be advisable. In this regard, we(More)
Therapeutic strategies for the fatal neurodegenerative disease amyotrophic lateral sclerosis (ALS) are actually minimally effective on patients' survival and quality of life. Although stem cell therapy has raised great expectations, information on the involved molecular mechanisms is still limited. Here we assessed the efficacy of the systemic(More)

This article presents a stochastic model of lymphocyte recruitment in inflamed brain microvessels. Recent studies about the inflammatory process of the brain that leads to multiple sclerosis have revealed that lymphocyte extravasation is a sequence of dynamical states, mediated by partially overlapped interactions of different adhesion molecules and(More)
In this study we have examined the effects of interleukin 10 (IL-10) on polymorphonuclear leukocytes (PMN), and found that it is a potent inhibitor of tumor necrosis factor (TNF), IL-10, and IL-8 secretion triggered by lipopolysaccharide (LPS). Cytokine production by phagocytosing PMN was also inhibited by IL-10, but to a lesser extent than the LPS-induced(More)
