    Abstract Circulating levels of IgM anti-CD64, an immunosuppressive antibody recently identified in long-term stable multiple sclerosis (MS) patients, were found to fluctuate over time in MS patients. Antibody-positive patients showed a significantly lower annualized relapse rate value as well as reached sustained disability worsening and had a relapse in a significantly longer median time than those without antibody. Disease-modifying therapies (DMTs) only were the covariate influencing both the relapse occurrence and the disability accrual. Serum IgM anti-CD64 levels are associated with maintenance of clinical stability in MS and may be tested as a candidate biomarker predictive of benign course and favourable long-term response to DMTs treatment.

    Abstract The mechanism underlying the early invasion of the central nervous system by HIV-1 is unclear. Here, we summarize old and new findings supporting blood-brain barrier changes during HIV and experimental simian immunodeficiency virus (SIV) infection. The effect of inflammatory and toxic molecules secreted by monocytes and microglia on the functional integrity of tight junctions of brain endothelium is highlighted. Furthermore, recent findings on a possible direct role of the envelope and regulatory HIV-1 proteins (gp120, Tat, Nef) in causing the blood-brain barrier changes are reviewed. The possibility that these proteins, as circulating molecules, may bind to microvessel endothelial cells and cause blood-brain changes with no direct participation of the virus is raised. Several issues deserve further investigation and answers to these questions may provide keys for new therapeutic strategies in HIV-1 infection of the central nervous system.

    Abstract COR167, a novel CB2-selective high affinity agonist, was found to significantly inhibit, in a dose-dependent manner, the proliferation of both peripheral blood mononuclear cells and myelin basic protein-reactive T cell lines from normal healthy subjects and patients with relapsing-remitting multiple sclerosis (MS). In MS, a significantly higher inhibition was observed in patients on treatment with disease modifying drugs compared to those naive to treatment. The inhibitory activity of COR167 was exerted through a mixed mechanism involving atypical and incomplete shift of Th1 phenotype towards Th2 phenotype associated with slight reduction of IL-4 and IL-5 as well as strongly reduced levels of Th17-related cytokines. COR167 was also able to reduce in vitro migration of stimulated immunocompetent cells through human brain endothelium associated with a significant reduction of levels of several chemokines. These findings demonstrate that COR167 exerts potent immunomodulatory effects and confirm the cannabinoid CB2 receptor as a novel pharmacological target to counteract neuroinflammation.

    Abstract Background: Cannabinoid receptors have been detected in human gliomas and cannabinoids have been proposed as novel drug candidates in the treatment of brain tumors.
    Aims: To test the in vitro antitumor activity of COR167, a novel cannabinoid CB2-selective agonist displaying a high binding affinity for human CB2 receptors, on tumor cells isolated from human glioblastoma multiforme and anaplastic astrocytoma.
    Methods: Glioma cell cultures were established from two glioblastoma multiforme and two anaplastic astrocytomas. Proliferation was measured in the presence or absence of COR167 with a bromodeoxyuridine (BrdU) cell proliferation ELISA assay. CB2 receptor expression was detected by western blotting. Apoptosis was assessed with phycoerythrin (PE) annexin V flow cytometry kit. TGF-beta 1 and 2 levels were analyzed in culture supernatants with commercial ELISAs.
    Results: COR167 was found to significantly reduce the proliferation of both glioblastoma and anaplastic astrocytoma in a dose-dependent manner at lower doses than other known, less specific CB2 agonists. This activity is independent of apoptosis and is associated with a significant reduction of TGF-beta 1 and 2 levels in supernatants of glioma cell cultures.
    Conclusion: These findings add to the role of cannabinoid CB2 receptor as a possible pharmacological target to counteract glial tumor growth and encourage further work to explore any other pharmacological effect of this novel CB2 agonist useful in the treatment of human gliomas.

    Abstract In multiple sclerosis, neuropathic pain is a frequent condition, negatively influencing the overall quality of life. Cranial neuralgias, including trigeminal, glossopharyngeal neuralgias, as well as occipital neuralgia, are typical expression of neuropathic pain. Neuralgias are characterised by paroxysmal painful attacks of electric shock-like sensation, occurring spontaneously or evoked by innocuous stimuli in specific trigger areas. In multiple sclerosis, demyelination in the centrally myelinated part of the cranial nerve roots plays an important role in the origin of neuralgic pain. These painful syndromes arising in multiple sclerosis are therefore considered "symptomatic", in contrast to classic cranial neuralgias, in which no cause other than a neurovascular contact is identified. At this time, the evidence on the management of symptomatic cranial neuralgias in multiple sclerosis is fragmentary and a comprehensive review addressing this topic is still lacking. For that reason, treatment is often based on personal clinical experience as well as on anecdotal reports. The aim of this review is to critically summarise the latest findings regarding the pathogenesis, the diagnosis, the instrumental evaluation and the medical as well as neurosurgical treatment of symptomatic trigeminal, glossopharyngeal and occipital neuralgia in multiple sclerosis, providing useful insights for neurologists and neurosurgeons and a broad range of specialists potentially involved in the treatment of these painful syndromes.

    Abstract Purpose: Fingolimod is the first oral drug approved for treatment of relapsing-remitting multiple sclerosis (RR-MS), and it has potential macular side effects. Despite the qualitative evidence of macular oedema under treatment, longitudinal quantitative assessment is lacking. To address this issue, we measured macular volume and central foveal thickness in a cohort of MS patients on fingolimod over 12 months of treatment.
    Methods: Central foveal thickness (CFT) and total macular volume (TMV) were longitudinally recorded with spectral-domain optical coherence tomography in a cohort of 23 RR-MS patients treated with fingolimod at baseline, 3, 6 and 12 months. OCT parameters were analysed considering previous history of optic neuritis (ON). Comparison of means was performed with variance analysis (ANOVA).
    Results: Macular oedema occurred in none of the patients. Comparing both groups of patients (with and without previous ON), no statistically significant difference was found during the follow-up both for CFT and TMV (p = 0.99 and p = 0.96, respectively) although a slight early but not significant TMV reduction was detected.
    Conclusions: In our cohort, therapy with fingolimod did not cause any change in CFT and TMV in MS patients during a 12-month follow-up independent of previous ON.
