Suppressor of cytokine signaling (SOCS) proteins are feedback inhibitors of the JAK/STAT pathway. SOCS3 has a crucial role in inhibiting STAT3 activation, cytokine signaling, and inflammatory gene expression in macrophages/microglia. To determine the role of SOCS3 in myeloid cells in neuroinflammation, mice with conditional SOCS3 deletion in myeloid cells (LysMCre-SOCS3(fl/fl)) were tested for ...

The major challenge for progressive multiple sclerosis therapy is the promotion of remyelination from inflammation-induced demyelination. A switch from an M1- to an M2-dominant polarization of microglia is critical in these repair processes. In this study, we identified the homeobox gene msh-like homeobox-3 (Msx3) as a new pivotal regulator for microglial polarization. MSX3 was induced during m...

vicia sativa l., an annual winter growing leguminous plant, is a valuable source of protein and minerals for cattle. drought is one of the key stress factors that influence plant growth and development. in order to investigate common vetch physiological and molecular responses under normal irrigation (n) and two levels of drought stress [s1= 30% and s2= 10% field capacity (fc)], a greenhouse exp...

Interleukin 17 (IL-17), produced mainly by T helper 17 (Th17) cells, is increasingly recognized as a key regulator in various autoimmune diseases, including human multiple sclerosis (MS) and its animal model, experimental autoimmune encephalomyelitis (EAE). Although several microRNAs (miRNAs) with aberrant expression have been shown to contribute to the pathogenesis of MS and EAE, the mechanism...

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...

Multiple sclerosis (MS) is the most common chronic inflammatory demyelinating disease of the central nervous system (CNS) in young adults. Chronic treatments with histone deacetylase inhibitors (HDACis) have been reported to ameliorate experimental autoimmune encephalomyelitis (EAE), a rodent model of MS, by targeting immune responses. We have recently shown that the HDAC inhibition/knockdown i...

Objective(s): In the present study, C57BL/6 female mice (n=56) were used to explore the neuroprotective effects of riboflavin in motor disability of experimental autoimmune encephalomyelitis (EAE) as a model of multiple sclerosis. Materials and Methods: The animals were assigned into 7 groups: sham-operated 1 (SO1), healthy mice receiving PBS (phosphate buffer saline); sham-operated 2 (SO2), h...

The paracaspase MALT 1 is a major player in lymphocyte activation and proliferation. MALT1 mediates Ag-induced signaling to the transcription factor NF-κB by functioning both as a scaffold protein and cysteine protease. We studied the role of MALT1 in the development of experimental autoimmune encephalomyelitis (EAE), an animal model of multiple sclerosis. MALT1-knockout mice did not develop an...

Experimental autoimmune encephalomyelitis (EAE) is a CD4+ Th1-mediated demyelinating disease of the central nervous system that serves as a model for multiple sclerosis (MS). There are several considerations that suggest a role for chemokines in the disease process. First, chemokines are highly expressed in the central nervous system with a tight temporal relationship to disease activity. Secon...

Inflammation leads to induction of tissue stress conditions that might contribute to the generation of mechanisms limiting ongoing immune responses. We have shown previously that peptides derived from brain tissue of mice with experimental autoimmune encephalomyelitis (EAE) complexed with the chaperone heat shock protein 70 (Hsp70-pc) induce an NK-cell-dependent tolerance for subsequent EAE sen...
