Increased EBV Reactivation in the Cerebrospinal Fluid of Patients with Early Multiple Sclerosis

Epstein-Barr virus (EBV) has been consistently associated with multiple sclerosis (MS), but whether this virus is a trigger of MS remains undetermined. Recently, EBV-infected B cells recognized by activated CD8_ T cells have been detected in the meninges of autopsied MS patients. In addition, a strong EBV-specific CD8_ T cell response in the blood of patients with MS of recent onset was reported. Here, to further explore the putative relationship between MS and EBV, we assessed the EBV-specific cellular and humoral immune responses in the blood and the cerebrospinal fluid (CSF) of patients with early MS or other neurological diseases, separated into inflammatory (IOND) and non-inflammatory (NIOND) groups. The MS non-associated neurotropic herpesvirus cytomegalovirus (CMV) served as a control. Fifty-eight study subjects were enrolled, including 44 patients (13 with early MS (onset of MS less than one year prior to the assay), 15 with IOND and 16 with NIOND) in the immunological arm of the study. The cellular immune response was investigated using a functional CFSE cytotoxic T lymphocyte (CTL) assay performed with short-term cultured EBV- or CMVspecific effector T cells from the CSF and the blood. The humoral immune response specific for these two viruses was also examined in both the blood and the CSF. The recruitment of a given virusspecific antibody in the CSF as compared to the blood was expressed as antibody indexes (AI). We found that, in the CSF of early MS patients, there was an enrichment in EBV-, but not CMV-specific, CD8_ CTL as compared to the CSF of IOND (P_ 0.003) and NIOND patients (P_0.0009), as well as compared to paired blood samples (P_0.005). Additionally, relative viral capsid antigen (VCA)-, but not EBV encoded nuclear antigen 1 (EBNA1)- or CMV-specific, AI were increased in the CSF of early MS as compared to IOND (P_0.002) or NIOND patients (P_0.008) and correlated with the EBVspecific CD8_ CTL responses in the CSF (rs_0.54, P_0.001). Fourteen additional patients were enrolled in the virological arm of the study: using semi-nested PCR, EBV-encoded nuclear RNA1 (EBER1)-a transcript expressed during all stages of EBV infection-was detected in the CSF of 2/4 early MS, but only 1/6 IOND and 0/4 NIOND patients. Altogether, our data suggest that a reactivation of EBV, but not CMV, is taking place in the central nervous system of patients with MS of recent onset. These data significantly strengthen the link between EBV and MS and may indicate a triggering role of EBV in this disease. This work was supported by grants from the Swiss National Foundation and from the Swiss Society for Multiple Sclerosis.

Quantification of 4 antidepressants and a metabolite by LC-MS for therapeutic drug monitoring.

A liquid chromatography method coupled to mass spectrometry was developed for the quantification of bupropion, its metabolite hydroxy-bupropion, moclobemide, reboxetine and trazodone in human plasma. The validation of the analytical procedure was assessed according to Société Française des Sciences et Techniques Pharmaceutiques and the latest Food and Drug Administration guidelines. The sample preparation was performed with 0.5mL of plasma extracted on a cation-exchange solid phase 96-well plate. The separation was achieved in 14min on a C18 XBridge column (2.1mm×100mm, 3.5μm) using a 50mM ammonium acetate pH 9/acetonitrile mobile phase in gradient mode. The compounds of interest were analysed in the single ion monitoring mode on a single quadrupole mass spectrometer working in positive electrospray ionisation mode. Two ions were selected per molecule to increase the number of identification points and to avoid as much as possible any false positives. Since selectivity is always a critical point for routine therapeutic drug monitoring, more than sixty common comedications for the psychiatric population were tested. For each analyte, the analytical procedure was validated to cover the common range of concentrations measured in plasma samples: 1-400ng/mL for reboxetine and bupropion, 2-2000ng/mL for hydroxy-bupropion, moclobemide, and trazodone. For all investigated compounds, reliable performance in terms of accuracy, precision, trueness, recovery, selectivity and stability was obtained. One year after its implementation in a routine process, this method demonstrated a high robustness with accurate values over the wide concentration range commonly observed among a psychiatric population.

New Radicals and new applications of Dynamic Nuclear Polarization of biological systems

Dynamic Nuclear Polarization (DNP) is an emerging technique that could revolutionize the NMR study of small molecules at very low concentrations by the increase in sensitivity that results from transfer of polarization between electronic and nuclear spins. Although the underlying physics has been known for a long time, in the last few years there has been a lot of excitement on the chemistry and biology NMR community caused by the demonstration that the highly polarized nuclei that are prepared in solid state at very low temperatures (1-2 K) could be rapidly transferred to liquid samples at room temperature and studied in solution by conventional NMR techniques. In favorable cases several order of magnitude increases in sensitivity have been achieved. The technique is now mature enough that a commercial instrument is available. The efficiency of DNP depends on two crucial aspects: i) the efficiency of the nuclear polarization process and ii) the efficiency of the transfer from the initial solid state to the fluid state in which NMR is measured. The preferred areas of application (iii) will be dictated by situations in which the low concentration of the sample or its intrinsic low receptivity are the limiting factors .

Fluid flow through the sedimentary cover in northern Switzerland recorded by calcite-celestite veins (Oftringen borehole, Olten)

Abundant veins filled by calcite, celestite and pyrite were found in the core of a 719 m deep borehole drilled in Oftringen near Olten, located in the north-western Molasse basin, close to the thrust of the Folded Jura. Host rocks are calcareous marl, argillaceous limestone and limestone of the Dogger and Malm. The delta O-18 values of vein calcite are lower than in host rock carbonate and, together with microthermometric data from fluid inclusions in vein calcite, indicate precipitation from a seawater-dominated fluid at average temperatures of 56-68A degrees C. Such temperatures were reached at the time of maximum burial of the sedimentary pile in the late Miocene. The depth profile of delta C-13 and Sr-87/Sr-86 values and Sr content of both whole-rock carbonate and vein calcite show marked trends towards negative delta C-13, high Sr-87/Sr-86, and low Sr content in the uppermost 50-150 m of the Jurassic profile (upper Oxfordian). The Sr-87/Sr-86 of vein minerals is generally higher than that of host rock carbonate, up to very high values corresponding to Burdigalian seawater (Upper Marine Molasse, Miocene), which represents the last marine incursion in the region. No evidence for internally derived radiogenic Sr (clay minerals) has been found and so an external source is required. S and O isotope composition of vein celestite and pyrite can be explained by bacterial reduction of Miocene seawater sulphate. The available data set suggests the vein mineralization precipitated from descending Burdigalian seawater and not from a fluid originating in the underlying Triassic evaporites.
