Naive T helper cells differentiate into functionally distinct effector subsets that drive specialized immune responses. Recent studies indicate that some of the effector subsets have plasticity. Here, we used an EAE model and found that Th17 cells deficient in the transcription factor BCL11B upregulated the Th2-associated proteins GATA3 and IL-4 without decreasing RAR-related orphan receptor γ ...

background and objectives: enteropathogenic escherichia coli (epec) strains can be detected by serogrouping and the presence of enterocyte attaching- effacing (eae) gene. most epec strains belong to a certain o antigenic group. locus of enterocyte effacement (lee) pathogenicity island contains the eae gene and secretory proteins (esps) that introduce the attaching-effacing lesion. lee inserted ...

We previously reported that mice with experimental autoimmune encephalomyelitis (EAE), a model of multiple sclerosis (MS), develop profound urinary bladder dysfunction. Because neurogenic bladder in MS patients causes marked bladder remodeling, we next examined morphometric and molecular alterations of the bladder in EAE mice. EAE was created in female SJL/J mice by immunization with the p139-1...

We recently demonstrated that human C-reactive protein (CRP), expressed hepatically in transgenic mice (CRPtg), improved the outcome of experimental autoimmune encephalomyelitis (EAE), a murine model of multiple sclerosis (MS). The liver is the primary site of CRP synthesis in humans and in CRPtg mice but is also expressed by both at low levels in the CNS. To determine if CNS expression of huma...

Estrogens can signal through either estrogen receptor α (ERα) or β (ERβ) to ameliorate experimental autoimmune encephalomyelitis (EAE), the most widely used mouse model of multiple sclerosis (MS). Cellular targets of estrogen-mediated neuroprotection are still being elucidated. Previously, we demonstrated that ERα on astrocytes, but not neurons, was critical for ERα ligand-mediated neuroprotect...

Adoptive transfer experimental autoimmune encephalomyelitis (AT-EAE) is an inflammatory demyelination that recapitulates in mouse spinal cord (SC) the human multiple sclerosis disease. We now analyze previously reported cDNA array data from age-matched young female adult control and passively myelin antigen-sensitized EAE mice with regard to organizational principles of the SC transcriptome in ...

IL-27 has been shown to play a suppressive role in experimental autoimmune encephalomyelitis (EAE) as demonstrated by more severe disease in IL-27R-deficient (WSX-1(-/-)) mice. However, whether IL-27 influences the induction or effector phase of EAE is unknown. This is an important question as therapies for autoimmune diseases are generally started after autoreactive T cells have been primed. I...

TWIK2 ion channels (K2P6.1, encoded by a gene named Kcnk6) belong to the family of two-pore domain potassium channels. TWIK2 is also considered as a “silent” channel because of its inability to produce measurable currents in heterologous expression systems and its intracellular retention. It is expressed in different mammalian tissues including lymphoid organs and the vascular syste...

The heparan sulfate-cleaving enzyme heparanase (HPSE) plays an important role in remodeling of the basement membrane and extracellular matrix during inflammation. Inducible HPSE enzymatic activity has been reported in leukocytes; however, little is known of the molecular mechanisms that regulate HPSE gene expression during inflammatory disease. In this study, HPSE expression and regulation in t...

BACKGROUND To elucidate mechanisms involved in multiple sclerosis (MS), we studied genetic regulation of experimental autoimmune encephalomyelitis (EAE) in rats, assuming a conservation of pathogenic pathways. In this study, we focused on Eae23, originally identified to regulate EAE in a (LEW.1AV1xPVG.1AV1)F2 cross. Our aim was to determine whether one or more genes within the 67 Mb region regu...
