title: Reciprocal age-dependent pattern of two neuronal markers, tetanus toxin and neuron-specific enolase, in postnatal rat sensory and sympathetic neurons.
abstract: Tetanus toxin (TT) and antibodies to neuron-specific enolase (NSE) were used to study the developmentally regulated expression of two neuronal markers in isolated and short-term cultured rat sensory and sympathetic neurons at different postnatal ages. The results show a reciprocal pattern of TT binding and NSE-immunoreactive neurons during postnatal maturation: there is a gradual transition from TT-positive, NSE-negative to TT-negative, NSE-positive phenotypic expressions. We conclude that TT may serve as a neuronal marker for newborn, anti-NSE antibodies as markers for adult neurons, and a combination of both for adolescent neurons.
