摘要: Brain-derived neurotrophic factor and neurotrophin-3 deficient mice were generated by gene targeting. The analysis of these has led to the characterization their role in survival neurons peripheral nervous system. NT-3 displayed severe movement defects most died shortly after birth. mutation causes loss substantial portions cranial spinal sensory sympathetic neurons. Significantly, proprioceptive afferents sense organs (muscle spindles Golgi tendon organs) completely absent homozygous mutant mice. BDNF deficiencies coordination balance. Excessive was detected ganglia examined, but not affected. marked reduction observed vestibular ganglion, leading a innervation epithelia compartments inner ear.
