Abstract
Drug development for multiple sclerosis (MS) clinical management focuses on both neuroprotection and repair strategies, and is challenging due to low permeability of the blood-brain barrier, off-target distribution, and the need for high doses of drugs. The changes in the extracellular matrix have been documented in MS patients. It has been shown that the expression of nidogen-1 increases in MS lesions. Laminin forms a stable complex with nidogen-1 through a heptapeptide which was selected to target the lesion area in this study. Here we showed that the peptide binding was specific to the injured area following lysophosphatidylcholine (LPC) induced demyelination. In vivo data showed enhanced delivery of the peptide-functionalized gold nanoparticles (Pep-GNPs) to the lesion area. In addition, Pep-GNPs administration significantly enhanced myelin content and reduced astrocyte/microglia activation. Results demonstrated the possibility of using this peptide to target and treat lesions in patients suffering from MS.

Abstract
Despite the significant differences in pathological background of neurodegenerative diseases, epileptic seizures are a comorbidity in many disorders such as Huntington disease (HD), Alzheimer's disease (AD), and multiple sclerosis (MS). Regarding the last one, specifically, it has been shown that the risk of developing epilepsy is three to six times higher in patients with MS compared to the general population. In this context, understanding the pathological processes underlying this connection will allow for the targeting of the common and shared pathological pathways involved in both conditions, which may provide a new avenue in the management of neurological disorders. This review provides an outlook of what is known so far about the bidirectional association between epilepsy and MS.

Abstract
Sox2 transcription factor has been frequently used for reprograming starting cells to neural progenitor/stem cells. In vivo administration of Sox2 in the adult mouse brain reprogrammed the transduced astrocytes to neurons. In searching for adequate cell source for repairing the myelin insults, here, we studied the possible conversion of astrocytes to oligodendrocyte lineage cells by Sox2, while an extensive demyelination exists in animal brain. Lentiviral particles expressing Sox2-GFP were injected into the corpora callosa of animals fed with cuprizone diet for 12 weeks. Transduced cells were mainly astrocytes that changed their fate to oligodendrocyte lineage cells by time. For further conformation astrocytes received the vector in culture and then transplanted to the animal brains. Tracing the fate of transplanted cells showed their conversion to oligodendrocyte lineage cells. In vitro transduced cell were also maintained in the oligodendrocyte progenitor cell (OPC) induction medium. Produced OPC-like cells were positive for specific markers. This study provides a new strategy for endogenous production of myelinating cells. After optimizing the experimental conditions for safety and feasibility, this approach may contribute into future cell based therapies in patients with white matter insults as like as those with multiple sclerosis.

Abstract
PURPOSE This study was designed to compare the efficacy and safety of oral versus intravenous ganciclovir in high-risk kidney recipients. METHODS Thirty-four, cytomegalovirus (CMV) seropositive recipients of kidneys from seropositive donors who had undergone antilymphocytic immunosuppressive therapy were assigned randomly to oral (1000 mg, three times a day, 12 weeks) versus intravenous (5 mg/kg, 2 weeks) ganciclovir prophylaxis. Follow-up was performed for 12 months. The patients were evaluated for clinical and laboratory outcomes regarding CMV serostatus, CMV disease, graft outcome, and ganciclovir side effects. RESULTS Sixteen patients in the oral group and 14 in the intravenous group completed the study. CMV infection occurred in 6 (37.5%) and 5 (35.7%) cases in the oral and intravenous groups, respectively (P = NS). The mean interval between prophylaxis initiation and the first positive CMV Ag result was 3 +/- 2.19 months, with no significant difference between the two groups. Only two patients in the intravenous group experienced CMV diseases, which were not tissue-invasive. Acute rejection episodes were observed in nine out of 30 recipients, but it did not show any association with the prophylaxis regimen or CMV serostatus. The patients tolerated oral ganciclovir well; the compliance percent was 81.6%. No complication was reported. CONCLUSION Oral and intravenous ganciclovir showed no significant difference to reduce the rate of CMV infection among high-risk kidney recipients. Oral ganciclovir was also effective and safe for the prevention of CMV disease. Moreover, it seems that CMV infection was not associated with acute rejection episodes.
