BACKGROUND AND PURPOSE Experimental autoimmune encephalomyelitis (EAE) in the marmoset was monitored by serial MR imaging to determine correlates to the natural-history MR studies in multiple sclerosis (MS). The relationships of MR-revealed lesions to clinical status and histopathologic findings were also explored. METHODS We induced EAE by subcutaneous inoculation in two marmosets by human w...

Inhibition of phospholipase A(2) (PLA(2)) has recently been found to attenuate the pathogenesis of experimental autoimmune encephalomyelitis (EAE), a commonly used animal model of multiple sclerosis (MS). However, the protective mechanisms that underlie PLA(2) inhibition are still not well understood. In this study, we found that cytosolic PLA(2) (cPLA(2)) was highly expressed in infiltrating l...

Organ-specific autoimmune diseases are characterized by infiltrates, including T lymphocytes and activated macrophages. Macrophages and secondarily activated tissue resident counterparts can both present Ag to and contribute to cytokine secretion by T lymphocytes. We have previously shown a crucial role of peripheral macrophages in experimental allergic encephalomyelitis (EAE), a Th1-mediated d...

In multiple sclerosis (MS) and in its animal model, Experimental Autoimmune Encephalomyelitis (EAE), autoagressive and regulatory cells traffic into the Central Nervous System (CNS), and may alter the course of the disease. Consequently the role of immunocompetent cells is major determinants in EAE pathogenesis for instance, CD4 T helper 1 cells, have been identified as a key element in determi...

Therapies that target leukocyte trafficking pathways can reduce disease activity and improve clinical outcomes in multiple sclerosis (MS). Experimental autoimmune encephalomyelitis (EAE) is a widely studied animal model that shares many clinical and histological features with MS. Chemokine-like receptor-1 (CMKLR1) is a chemoattractant receptor that is expressed by key effector cells in EAE and ...

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...

BACKGROUND In multiple sclerosis, inflammation can successfully be prevented, while promoting repair is still a major challenge. Microglial cells, the resident phagocytes of the central nervous system (CNS), are hematopoietic-derived myeloid cells and express the triggering receptor expressed on myeloid cells 2 (TREM2), an innate immune receptor. Myeloid cells are an accessible source for ex vi...

Systemic injection of small amounts of transforming growth factor(TGF), a cytokine produced by lymphoid and other cells, has a profound effect in protecting mice from the inflammatory demyelinating lesions of experimental allergic encephalomyelitis (EAE; an animal model for multiple sclerosis). However, TGFhas side-effects, which might be avoided if the cells producing TGFcan be delivered to th...

Predominance of multiple sclerosis (MS) in women, reductions of disease flares during pregnancy, and their increase in the postpartum period have suggested a hormonal influence on MS activity. The hormone prolactin (PRL) has long been debated as a potential immune-stimulating factor in several autoimmune disorders, including MS and its animal model experimental autoimmune encephalomyelitis (EAE...

The study of an autoimmune disease model such as experimental allergic encephalomyelitis (EAE)' will hopefully reveal a means to control such disease. EAE is an antigen-specific T cell-mediated disease that is considered to be a model for multiple sclerosis due toits similar pattern ofcentral nervous system (CNS) lesions and demyelination (1, 2) . This disease was first noted in patients whohad...
