Abstract

Teneurins (TENs) represent transmembrane type II proteins highly conserved among the species and mainly expressed in the central nervous system (CNS). This family is constituted by four homologues named as teneurins 1-4 in vertebrates. These proteins exert an important role in the neuronal interaction, besides a possible regulatory activity in gene transcription. Previous studies determined that the terminal exon of each teneurin has a genomic sequence able to translate a peptide exhibiting high homology to corticotrophin-releasing factor (CRF). These peptides were named as c-terminal associated peptides (TCAP1-4), exerting significant modulatory activity in behavior disorders linked to stress. Studies focusing TENs and TCAPs have been of large interest, in view of the possible therapeutic applications of these peptides. However, basic information on these new peptidergic systems, such as their neuroanatomical distribution in the primate brain needs to be elucidated, in order to support their physiological findings and pharmacological use. Consequently, the present study aims to evaluate the detailed distribution of neurons exhibiting immunoreactivity to TENs1-4 and TCAPs1-4 in the non-human primate brain (Cebus apella) using immunohistochemistry and in situ hybridization methods.
