INTRODUCTION The p75 neurotrophin receptor has been recognized as a death-signalling molecule under certain circumstances. Its role in motor neuron degeneration in amyotrophic lateral sclerosis (ALS) was analysed in SOD1-G93A transgenic mice and in spinal cords from human amyotrophic lateral sclerosis. METHOD The precise loss of motor neurons in SOD1-G93A(More)
The 75 kD low-affinity neurotrophin receptor (p75(NTR)) is expressed in developing and axotomised spinal motor neurons. There is now convincing evidence that p75(NTR) can, under some circumstances, become cytotoxic and promote neuronal cell death. We report here that a single application of antisense p75(NTR) oligodeoxynucleotides to the proximal nerve(More)
Motor neurons are lost during embryonic development, but it remains controversial whether motor neuron cell death occurs during postnatal life. In this study we investigated the effect of postnatal maturation on the number of intact spinal motor neurons in the rat using retrograde labelling with model-based counting, and an unbiased stereological counting(More)
The low affinity neurotrophin receptor (p75(NTR)) is implicated in promoting oligodendrocytic death after nerve growth factor (NGF) stimulation but NGF and neurotrophin-3 (NT-3) can also potentiate oligodendrocytic survival. We show regional variability in p75(NTR) expression within the central nervous system of the postnatal rat; expression is readily(More)
The 75-kDa low-affinity neurotrophin receptor (p75NTR) has been shown in previous reports to mediate neuronal cell death in vitro and in vivo under certain circumstances. Antisense oligonucleotides directed against p75NTR promote the survival of nerve growth factor-deprived dorsal root ganglia sensory neurons in vitro (Barrett, G.; Bartlett, P., Proc. Natl.(More)
