Presentation of the self antigen myelin basic protein by dendritic cells leads to experimental autoimmune encephalomyelitis.
Bone marrow (BM)-derived dendritic cells (DC) are potent stimulators of naive CD4+ T cell activation. Because DC are efficient at Ag processing and could potentially present self Ags, we investigated the role of DC in the presentation of an encephalitogenic peptide from myelin basic protein (Ac1-11) in the induction of experimental autoimmune encephalomyelitis (EAE). To determine if DC could pr...
متن کاملA fusion protein consisting of IL-16 and the encephalitogenic peptide of myelin basic protein constitutes an antigen-specific tolerogenic vaccine that inhibits experimental autoimmune encephalomyelitis.
To test a novel concept for the generation of tolerogenic vaccines, fusion proteins were constructed encompassing a tolerogenic or biasing cytokine and the major encephalitogenic peptide of guinea pig myelin basic protein (GPMBP; i.e., neuroantigen or NAg). The cytokine domain was predicted to condition APC while simultaneously targeting the covalently linked encephalitogenic peptide to the MHC...
متن کاملExperimental autoimmune encephalomyelitis disrupts endocannabinoid-mediated neuroprotection.
Focal cerebral ischemia and traumatic brain injury induce an escalating amount of cell death because of harmful mediators diffusing from the original lesion site. Evidence suggests that healthy cells surrounding these lesions attempt to protect themselves by producing endocannabinoids (eCBs) and activating cannabinoid receptors, the molecular target for marijuana-derived compounds. Indeed, acti...
متن کاملTargeting Non-classical Myelin Epitopes to Treat Experimental Autoimmune Encephalomyelitis
Qa-1 epitopes, the peptides that bind to non-classical major histocompatibility complex Ib Qa-1 molecules and are recognized by Qa-1-restricted CD8+ regulatory T (Treg) cells, have been identified in pathogenic autoimmune cells that attack myelin sheath in experimental autoimmune encephalomyelitis (EAE, an animal model for multiple sclerosis [MS]). Additionally, immunization with such epitopes ...
متن کاملBilirubin possesses powerful immunomodulatory activity and suppresses experimental autoimmune encephalomyelitis.
Bilirubin, an abundant bile pigment in mammalian serum, was once considered a toxic waste product and has more recently been recognized as a potent antioxidant of physiological importance. However, its potential biological functions in other fields are not well understood. Herein we show that bilirubin is also a powerful immunomodulatory agent. Bilirubin significantly inhibited Ag-specific and ...
