The IgG indices for all participants in this study were also analyzed according to Reiber Figure S2 in File S1 and on this basis significant elevations were observed in some patients in all three MS cohorts [ 38 ]. In this study, 11 SPMS subjects had two lumbar punctures performed months apart average days apart and 9 RRMS subjects undergoing an exacerbation had a lumbar puncture and then received treatment with high dose IVMP.

A second lumbar puncture was performed one month after treatment. In general, the chemokine levels were stable over time Figure 7. The goal of this study was to explore measurement and analysis methods to compare the levels of chemokines in both the serum and CSF in the relapsing and progressive phases of MS. The composite chemokine scores defined here are promising and can be applied to future studies. In these small cohorts of patients with relatively advanced disease, neither group of chemokines tracked preferentially with one particular disease stage. Heterogeneity in disease status, medication usage, advanced disease or substantial contributions of subclinical disease may have masked potential differences in the chemokine patterns and larger studies would be required to elucidate this important question.

This study confirms and extends previous observations demonstrating that both inflammatory and lymphoid chemokines are elevated in the CSF in RRMS especially during exacerbation [ 13 , 16 , 22 , 23 , 28 , 34 , 39 , 41 , 42 ]. While the magnitude of the chemokine response varied by disease stage, the relative proportion of inflammatory or lymphoid chemokines did not vary substantially. The median interval from conversion to SPMS was 8. Older MS patients, i. Despite the readily detectable CNS inflammation, there was little change in the serum levels of these chemokines in any of the MS groups we studied. Barring the small size of this feasibility study, there are several scenarios that could explain the lack of qualitative differences in the CSF chemokine signatures between the stable RRMS and SPMS subjects we studied.

First, the general notion that lymphoid chemokines are preferentially associated with meningeal inflammation as opposed to CNS inflammation in general in MS could be erroneous. Second, the contribution of the progressive cortical component of the disease in SPMS may be small relative to the classical white matter component. Given the presence of substantial cortical inflammation early in the disease process i. There were some surprises in this analysis. CCL21 is efficiently immobilized onto matrix and in this state can drive T cell crawling along reticular networks or lymphocyte entry into lymphatic compartments. In contrast CCL19 remains more soluble and therefore may report more accurately on relative levels of immune activity.

CXCL12 is produced by the vasculature and astrocytes and is key for retention of lymphocytes within the perivascular compartment [ 43 ]. Loss of CXCL12 in rodent models allows lymphocytes to leave the perivascular space and enter the parenchyma. Our multiplexed data are effectively identical with one of the earlier reports [ 39 ]. The impact of elevated levels of CXCL12 on the disease process is unclear. In general, there have been few robust blood indicators of peripheral lymphoid involvement in MS [ 17 , 48 ]. This result is in stark contrast to other autoimmune diseases.

In this light, the levels of CXCL13 correlated well with the Q IgM values, an observation that could be consistent with the recent suggestion that IgM oligoclonal bands may track with brain atrophy and lesion load [ 40 , 49 ]. CCL2 is clearly induced in the injured or inflamed brain, especially in astrocytes, yet the results from quantitation of CCL2 levels in the normal rodent brain are mixed ranging from no detectable RNA to detectable RNA and protein [ 52 ]. Local chemokine production by myeloid lineage cells lining the meningeal compartments could also bias this ratio.

In summary, we developed robust methods for the measurement and analysis of inflammatory and lymphoid chemokines in the CSF of MS patients.

Abstract Meningeal inflammation, including the presence of semi-organized tertiary lymphoid tissue, has been associated with cortical pathology at autopsy in secondary progressive multiple sclerosis SPMS. Introduction The pathology that drives progressive forms of MS remains poorly understood. Serum and CSF collection When lumbar punctures were performed, venous blood samples were collected into serum separator tubes. Chemokine Multiplex Assay. Results Study subjects A total of 12 normal controls and 33 MS subjects from a single center were enrolled into the study and the baseline characteristics are defined in Table 2.
