The inflammatory response that accompanies central nervous system (CNS) injury can affect neurological outcome in both positive and negative ways. In the optic nerve, a CNS pathway that normally fails to regenerate when damaged, intraocular inflammation causes retinal ganglion cells (RGCs) to switch into an active growth state and extend lengthy axons down(More)
During development, radial glia cells contribute to neuronal migration and neurogenesis, and differentiate into astrocytes by the end of the developmental period. Recently, it was demonstrated that during development, radial glia cells, in addition to their role in migration, also give rise to neuroblasts. Furthermore, radial glial cells remain in the adult(More)
Bone marrow-derived cells have been used in different animal models of neurological diseases. We investigated the therapeutic potential of mesenchymal stem cells (MSC) injected into the vitreous body in a model of optic nerve injury. Adult (3-5 months old) Lister Hooded rats underwent unilateral optic nerve crush followed by injection of MSC or the vehicle(More)
The central nervous system (CNS) of adult mammals generally does not regenerate, and many studies have attempted to identify factors that could increase neuroprotection and/or axonal outgrowth after CNS lesions. Using the optic nerve crush of rats as a model for CNS injury, we investigated the effect of intravitreal transplantation of syngeneic bone-marrow(More)
Following optic nerve injury associated with acute or progressive diseases, retinal ganglion cells (RGCs) of adult mammals degenerate and undergo apoptosis. These diseases have limited therapeutic options, due to the low inherent capacity of RGCs to regenerate and due to the inhibitory milieu of the central nervous system. Among the numerous treatment(More)
Tuberculosis (TB) is still a major health concern and side-effects related to the treatment, especially drug-induced hepatotoxicity (DIH), should be better investigated. In the present study, a possible association between anti-TB DIH and cigarette smoking, N-acetyltransferase 2 (NAT2), Cytochrome P450 2E1 (CYP2E1) and Cytochrome P450 3A4 (CYP3A4) genotypes(More)
In adult mammals, the regeneration of the optic nerve is very limited and at the moment there are several groups trying different approaches to increase retinal ganglion cell (RGC) survival and axonal outgrowth. One promising approach is cell therapy. In previous work, we performed intravitreal transplantation of bone-marrow mononuclear cells (BMMCs) after(More)
PURPOSE Bone marrow mononuclear cells (BMMCs) have been used with considerable success to improve regeneration and/or functional recovery in animal models of neurologic diseases. Injected into the host, they migrate to the damaged areas and release cytokines and/or trophic factors, which are capable of altering the genetic program of the injured tissue(More)
The subventricular zone (SVZ) is recognized as one of the neurogenic regions in the adult mammalian central nervous system and the presence of cells that share similar characteristics with developmental radial glia, the radial glia-like cells (RGLCs) has been demonstrated in this region. In this study, we investigated whether and how SVZ cells respond to(More)
Amyotrophic lateral sclerosis (ALS) is a progressive neurological disease that selectively affects the motor neurons. The details of the mechanisms of selective motor-neuron death remain unknown and no effective therapy has been developed. We investigated the therapy with bone-marrow mononuclear cells (BMMC) in a mouse model of ALS (SOD1G93A mice). We(More)
