Their specializations enable the receptors to innervate unique central and peripheral targets. This differentiation takes place in each perinatal and postnatal periods. The nonpeptidergic nociceptors swap off the TrkA and begin expressing RET proto-oncogene, which happens to be a transmembrane signaling ingredient that enables the expression of glial cell line-derived neurotrophic component (GDNF).
