Aminopeptidase A (APA) and aspartyl aminopeptidase (ASAP) not only act as neuromodulators in the regional brain renin-angiotensin system, but also release N-terminal acidic amino acids (glutamate and aspartate). The hyperexcitability of amino acid neurotransmitters is responsible for several neurodegenerative processes affecting the central nervous system.(More)
State and function of breast depend on an endocrinological balance, the upsetting of which can be a factor favorable to the development of cancer. Enkephalins (ENK) have been considered as a particular form of adaptation to defense to the organism against neoplastic processes. However, ENK may modify the endocrine functions of glands such as the ovary or(More)
In the present review, the characteristics of mammalian neuropeptides have been studied. Neuropeptides are widely distributed not only in the nervous system but also in the periphery. They are synthesised by neurons as large precursor molecules (pre propeptides) which have to be cleaved and modified in order to form the mature neuropeptides. Neuropeptides(More)
Pyrrolidon carboxypeptidase (Pcp) is an omega peptidase that removes pyroglutamyl N-terminal residues of peptides such as thyrotrophin-releasing hormone (TRH), which is one of the neuropeptides that has been localized into many areas of the brain and acts as an endogenous neuromodulator of several parameters related to ethanol (EtOH) consumption. In this(More)
In developing cerebellum, where critical periods of vulnerability have been established for several basic substances, it has been extensively studied the wide array of abnormalities induced by exposure to ethanol (EtOH). However, little is known about the effects of EtOH consumption on cerebellar functions in adult individuals. Several studies show(More)
Pyroglutamyl aminopeptidase (pGluAP) is an omega peptidase that hydrolyzes biologically active peptides, such as thyrotropin-releasing hormone (TRH), with neuronal and extraendocrine functions. We analyzed the effects of a cholesterol-enriched diet on soluble and membrane-bound pGluAP activity in frontal cortex, pituitary and adrenal glands of male and(More)
