Bioinformatics Analyses Determined the Distinct CNS and Peripheral Surrogate Biomarker Candidates between Two Mouse Models for Progressive Multiple Sclerosis

ABSTRACT: Previously, we have established two distinct progressive multiple sclerosis (MS) models by induction of experimental autoimmune encephalomyelitis (EAE) with myelin oligodendrocyte glycoprotein (MOG) in two mouse strains. A.SW mice develop ataxia with antibody deposition, but no T cell infiltration, in the central nervous system (CNS), while SJL/J mice develop paralysis with CNS T cell infiltration. In this study, we determined biomarkers contributing to the heterogeneities of the two models. Using the CNS and spleen microarray transcriptome and cytokine data, we conducted computational supervised analyses (volcano plot, heat map, and pathway analysis) and unsupervised principal component analysis (PCA) with pattern matching analysis (PMA).

Myelin-reactive B cells exacerbate the severity of CD4+ T cell-driven CNS autoimmunity in an IL-23-dependent manner

Project description:B cells and T cells collaborate in multiple sclerosis (MS) pathogenesis. IgH[MOG]mice possess a B cell repertoire skewed to recognize myelin oligodendrocyte glycoprotein (MOG). Here, we show that upon immunization with the T cell-obligate autoantigen, MOG[35-55], IgH[MOG] mice develop rapid and exacerbated experimental autoimmune encephalomyelitis (EAE) relative to wildtype (WT) counterparts, characterized by aggregation of T and B cells in the IgH[MOG] meninges and by CD4+T helper 17 (Th17) cells in theCNS. Unusually, production of the Th17 maintenance factor IL-23 is observed from IgH[MOG]CNS-infiltrating and meningeal B cells, andin vivoblockade of IL-23p19 attenuates disease severity in IgH[MOG] mice. In the CNS parenchyma and dura mater of IgH[MOG] mice, we observe an increased frequency of CD4+PD-1+CXCR5-T cells that share numerous characteristics with the recently described T peripheral helper (Tph) cell subset. Further, CNS-infiltrating B and Tph cells from IgH[MOG] mice show increased reactive oxygen species (ROS) production. Meningeal inflammation, Tph-like cell accumulation in the CNS and B/Tph cell production of ROS were all reduced upon p19 blockade. Altogether, MOG-specific B cells promote autoimmune inflammation of the CNS parenchyma and meninges inan IL-23 dependent manner.

Transcriptional profile of the CNS of pups from Zika virus-infected SJL mothers treated with nanoliposomes loaded with AHR antagonist CH223191

Project description:SJL pregnant mice were infected with Zika virus and treated with nanoliposomes loaded with AHR antagonist CH223191 or control nanoliposomes. RNA-Seq analysis was performed in CNS samples from the pups.

Treatment with nanoliposomes loaded with ITE and MOG(35-55) ameliorates EAE

Project description:To evaluate the therapeutic potential of NLP(ITE+MOG) in a mouse model of secondary progressive multiple sclerosis, we induced EAE in NOD mice and initiated weekly treatment with nanoliposomes beginning at 35 days post immunization during the chronic phase of disease. NLP(ITE+MOG) administration ameliorated EAE, and the transcriptional analysis of CNS-resident astrocytes, microglia and monocytes revealed decreased expression of genes associated with pro-inflammatory responses and neurodegeneration.

Identification of gene expression patterns in lymphoma-prone SJL mice of different ages

Project description:SJL mice spontaneously develop mature B cell lineage lymphomas. These studies were designed to evaluate significant gene expression differences between spleens of control mice that do not develop lymphomas compared to spleens from SJL mice of differeing ages 22 samples were tested from 4 groups of mice - 10 samples from one group and 4 samples each from the other three groups. One sample per array

Whole-transcriptome microarray to identify sexually dimorphic RNA transcripts that are differentially expressed in disease-susceptible versus nonsusceptible CNS regions of male and female SJL mice

Project description:We hypothesized that sexual dimorphism in experimental autoimmune enecphalomyelitis arises from sexually dimorphic and CNS-region specific expression of genes that regulate BBB permeability and leukocyte entry. To test this hypothesis, we profiled total RNA from the cerebella and frontal cortices of naïve female versus male SJL mice 100 ng of total RNA was extracted from cerebella and frontal cortices of naïve SJL female and male littermates to identify differential expression of gene transcripts unique to female cerebellum.

CNS antigen-specific control of early B-lineage development in the meninges

Project description:In this work we report that early developing B cells present in the meninges of mice at all ages. Single cell RNA-sequencing (scRNA-seq) analysis revealed a consecutive trajectory of meningeal developing B cells in mice and non-human primates (NHPs). Parabiosis together with lineage tracing of hematopoietic stem cells (HSCs) showed that meningeal developing B cells are continuously replenished from the HSC-derived progenitors via a circulation-independent route. Importantly, autoreactive immature B cells which recognize myelin oligodendrocyte glycoprotein (MOG), a central nervous system (CNS)-specific antigen, are eliminated from the meninges but not BM. Furthermore, genetic deletion of MOG tolerated the development/presence/residence of self-reactive B cells in the meninges. Thus, we propose that meninges function as a unique reservoir for B cell development, allowing in situ negative selection of CNS-antigen-autoreactive B cell clones to ensure a local non-self-reactive immune repertoire.

Project description:in the current study we identified a miRNAs signature able to discriminate between typical and atypical endometrial hyperplasia the identification of molecular marker that can differentiate between these two distinct pathological conditions is highly considered to be useful for the clinical management of the patients, owing to the fact that hyperplasia with atypical change is associated with higher risk of develop cancer.

Gene expression profiling of mouse experimental autoimmune encephalomyelitis (EAE) from spinal cord preparations of opticospinal EAE (OSE) and MOG-induced EAE

Project description:Genetic opticospinal EAE (OSE) and MOG-induced EAE (MOG-EAE) are two experimental autoimmune encephalomyelitis (EAE) mouse models of human multiple sclerosis. For the OSE model, double-transgenic 2D2 (TCRMOG) x IgHMOG mice were used. For MOG-EAE, wildtype C57BL/6 mice were immunized with a MOG peptide consisting of the amino acids 35-55, administered in complete Freund’s adjuvant containing 5mg / ml Mycobacterium tuberculosi. The severity of EAE was rated on the scale 0: healthy animal; 1: animal with a flaccid tail; [...]; 4: animal with both hind legs paralyzed. The case groups in the experiment were: OSE1: OSE with disease score 1; OSE4: OSE with disease score 4; MOG4: MOG-EAE injected with both MOG and adjuvant, with disease score 4. The control groups in the experiment were: OSE0: OSE with disease score 0; CFA: C57BL/6 mice injected only with adjuvant (no MOG); WT: Wildtype C57BL/6 mice. The aim of the experiment was to assess gene expression differences 1) between OSE4 and OSE0, 2) between OSE1 and OSE0, and 3) between MOG4 and CFA. For control, WT was compared to OSE0 and CFA. Subsequently, differentially expressed transcripts were compared, first, between the OSE4 vs. OSE0 and the MOG4 vs. CFA contrasts (different EAE models) and, second, between the OSE4 vs. OSE0 and the OSE1 vs. OSE0 contrasts (different EAE severity).
