TGFalpha is a member of the epidermal growth factor (EGF) family with which it shares the same receptor, the EGF receptor (EGFR). Synthesis of TGFalpha and EGFR in reactive astrocytes developing after CNS insults is associated with the differentiative and mitogenic effects of TGFalpha on cultured astrocytes. This suggests a role for TGFalpha in the(More)
Motoneuronal degenerative diseases are characterized by their progressivity; once affected, the motoneurons remain in altered states during an intermediate phase of degeneration prior to their final disappearance. Whether this survival period coincides with active metabolic rearrangements in the affected neuron remains unknown. As a first step toward the(More)
Like other nonsteroidal anti-inflammatory drugs, nimesulide (4-nitro-2-phenoxymethane-sulfoanilide) triggers hepatitis in a few recipients. Although nimesulide has been shown to uncouple mitochondrial respiration and cause hepatocyte necrosis in the absence of albumin, mechanisms for cell death are incompletely understood, and comparisons with human(More)
