Brain insults such as the autoimmune inflammatory process in multiple sclerosis (MS) and experimental autoimmune encephalomyelitis (EAE) induce a measure of neurogenesis, but its regenerative therapeutic consequence is limited, because it fails to regenerate functional neurons and compensate the damage. Here, we investigated whether peripheral immunomodulatory treatment for MS/EAE, glatiramer a...

The spinal cord is a target of progesterone (PROG), as demonstrated by the expression of intracellular and membrane PROG receptors and by its myelinating and neuroprotective effects in trauma and neurodegeneration. Here we studied PROG effects in mice with experimental autoimmune encephalomyelitis (EAE), a model of multiple sclerosis characterized by demyelination and immune cell infiltration i...

Experimental allergic encephalomyelitis (EAE) serves as an animal model for certain neuroinflammatory diseases of the central nervous system, in particular multiple sclerosis (MS). EAE is accompanied by transient weakness or paralysis of hind limbs. We have investigated the effect of partial and transient conduction failure in the central nervous system on skeletal muscle function. At approxima...

INTRODUCTION Multiple sclerosis (MS) is an enigmatic autoimmune-driven inflammatory/demyelinating disease of the human central nervous system (CNS), affecting brain, spinal cord, and optic nerves. The cause of the disease is not known and the number of effective treatments is limited. Despite some clear successes, translation of immunological discoveries in the mouse experimental autoimmune enc...

Extracellular matrix metalloproteinase inducer (EMMPRIN, CD147) is a member of the Ig superfamily, with various physiological roles including the induction of matrix metalloproteinases (MMPs), leukocyte activation, and tumor progression. In this study, we illustrate a novel involvement of EMMPRIN in multiple sclerosis (MS) and its animal model, experimental autoimmune encephalomyelitis (EAE). W...

Objective We aimed to determine the role of the low-density lipoprotein receptor (LDLr) in neuroinflammation by inducing experimental autoimmune encephalomyelitis (EAE) in ldlr knock out mice. Methods MOG35-55 induced EAE in male and female ldlr-/- mice was assessed clinically and histopathologically. Expression of inflammatory mediators and apolipoprotein E (apoE) was investigated by qPCR. C...

Increased remissions in multiple sclerosis (MS) during late pregnancy may result from high levels of sex steroids such as estrogen and estriol. Estrogen (E2=17β-estradiol) protects against experimental autoimmune encephalomyelitis (EAE), but the cellular basis for E2-induced protection remains unclear. Treatment with relatively low doses of E2 can protect against clinical and histological signs...

Peroxisome proliferator-activated receptor (PPAR) is a family of nuclear receptor transcription factors that regulates immune cell growth, differentiation and homeostasis. We and others have shown earlier that in vivo treatment with PPAR , / or agonists ameliorates experimental autoimmune encephalomyelitis (EAE) model of multiple sclerosis (MS). In this study we show that C57BL/6 mice induced t...

Reactive oxygen species play a significant role in the pathogenesis of retinopathy in diabetes patients. The current study aimed to assess the effect of ethyl acetate extract (EAE) from Balanites aegyptiaca (10, 25 or 50 mg/kg b.w.) in experimental diabetic rats. To achieve this aim, five groups of male rats were included: control, diabetic, and diabetic rats treated with 10, 25, and 50 µg/kg b...

PI3Ks control signal transduction triggered by growth factors and G-protein-coupled receptors and regulate an array of biological processes, including cellular proliferation, differentiation, survival and migration. Herein, we investigated the role of PI3Kγ in the pathogenesis of EAE. We show that, in the absence of PI3Kγ expression, clinical signs of EAE were delayed and mitigated. PI3Kγ-defic...
