Endothelins (ETs) and their receptors are present in high levels in the brain and have been proposed to act as neuromodulators or neurotransmitters. However, neither their role nor their precise mechanism of action in the brain is understood. In this study, c-fos expression was used as a marker of neuronal activation in organotypic cultures of rat(More)
Autoreactive B lymphocytes that are not culled by central tolerance in the bone marrow frequently enter the peripheral repertoire in a state of functional impairment, termed anergy. These cells are recognized as a liability for autoimmunity, but their contribution to disease is not well understood. Insulin-specific 125Tg B cells support T cell-mediated type(More)
Endothelin (ET) is a potent vasoconstrictor which has also been proposed to act as a neuromodulator. We have investigated the action of ET-1 on neurones in vivo, using c-fos as a marker of neuronal activation. Intrastriatal injection of ET-1 caused seizures and barrel rolling which were prevented by pretreatment with the N-methyl-D-aspartate (NMDA) receptor(More)
