Their specializations allow the receptors to innervate various central and peripheral targets. This differentiation takes place in equally perinatal and postnatal durations. The nonpeptidergic nociceptors change from the TrkA and begin expressing RET proto-oncogene, that is a transmembrane signaling element that allows the expression of glial mobile line-derived neurotrophic element (GDNF).
