The study on the activity of the oligopeptidases Ndel1 (Nuclear distribution element-like 1) and angiotensin I converting enzyme (ACE) is motivated by the fact that these enzymes are neuropeptidases that act in the cleavage of neuropeptides such as neurotensin, which has already been demonstrated to be fundamental for response to antipsychotics and was also considered to be an endogenous antipsychotic. The neuropeptidergic pathway can modulate monoaminergic transmission, and changes in Ndel1 and ACE activity in individuals experiencing first-episode psychosis with schizophrenia have already been demonstrated. Therefore, we believe that evaluating the activity of these enzymes in animal models for mental disorders could contribute to better knowledge and perhaps to an understanding of the etiology of these disorders, such as schizophrenia and bipolar disorder.
