In vivo birthdating by BAPTISM reveals that trigeminal sensory neuron diversity depends on early neurogenesis.
Among sensory systems, the somatic sense is exceptional in its ability to detect a wide range of chemical, mechanical and thermal stimuli. How this sensory diversity is established during development remains largely elusive. We devised a method (BAPTISM) that uses the photoconvertible fluorescent protein Kaede to simultaneously analyze birthdate and cell fate in live zebrafish embryos. We found...
متن کاملBAPTI and BAPTISM birthdating of neurons in zebrafish.
This protocol describes how the photoconvertible protein Kaede can be used to determine the birthdates of neurons in live zebrafish. The methods used are birthdating analysis by photoconverted fluorescent protein tracing in vivo (BAPTI) and BAPTI combined with subpopulation markers (BAPTISM). Because Kaede can be converted from green to red fluorescence at any developmental time point, it serve...
متن کاملPainful Neuron-Microglia Interactions in the Trigeminal Sensory System
The trigeminal sensory system is unique in its innervation of structures specific to the orofacial area. Nociceptive trigeminal afferents are known to synapse with second-order neurons in the trigeminal subnucleus caudalis (Sp5C) in the brain stem. The activity of neurons within the Sp5C is responsible for the relay of nociceptive signals to higher brain centers. Recent evidence suggests that c...
متن کاملIn vivo effects of neurotrophin-3 during sensory neurogenesis.
The neurotrophins nerve growth factor, brain-derived neurotrophic factor and neurotrophin-3 are structurally related proteins regulating the number of neurons in peripheral ganglia of the nervous system. Increased levels of nerve growth factor or of brain-derived neurotrophic factor selectively prevent normally occurring neuronal death, while the targeted elimination of all three genes decrease...
متن کاملGeneration of somatic sensory neuron diversity and implications on sensory coding.
Neurons in the dorsal root ganglia (DRG) are composed of a variety of sensory modalities, three of which are pain-sensing nociceptors, temperature-sensing thermoceptors, and itch-sensing pruriceptors. All these neurons are emerged from a common pool of embryonic DRG neurons that are marked by the expression of the neurotrophin receptor TrkA. Here we discuss how intrinsic transcription factors i...
