What is GLP-3? A Detailed Overview of Science

GLP-3 has become one of the most interesting topics of research in metabolic biology and peptide studies. This follows the rise of GLP-1 as one of the greatest peptides in the history of modern medical research. For a long time, the attention of the scientific community was focused on the physiological and clinical significance of GLP-1. Several successes in the treatment of diabetes, obesity, and other metabolic disorders have been achieved thanks to the studies of GLP-1. Jedoch, in contrast to GLP-1, GLP-3 has not yet drawn much attention to itself and remained mostly unexplored and understudied. Jedoch, the continuous improvement of molecular investigations, gene sequencing, and in situ experiments has eventually opened new frontiers in the investigation of GLP-3`s biological properties, functions, and importance for science.
GLP-3, which stands for glucagon-like peptide 3, refers to the family of glucagon-like peptides, which all originate from the transcription of proglucagon, a highly conservative gene in mammals which produces several peptides from different tissues and under different conditions, including glucagon, GLP-1, GLP-2, and GLP-3. Unlike GLP-1 and GLP-2, which already have established sequences and functions, GLP-3 is a relatively new subtype of peptide with a different sequence and biological function.While the presence of this peptide was shown in neurons of the brain and pancreas, it is mainly produced and released in intestinal endocrine cells, which demonstrates some distinct features of tissue-specific expression.
In order to understand better the peptide GLP-3, one should clarify its difference from the famous GLP-1. Although both peptides come from the same gene precursor and possess some structural commonalities, their functions are different. GLP-1 does have some important properties providing the insulin secretion, which allows one to maintain the blood sugar level in the body, prevent glucagon from being released, slow the process of gastric emptying, and suppress hunger. GLP-2 is mainly characterized as the peptide which manages mucosal growth, restores the function of the intestinal barrier, and ensures the absorption of nutrients. Jedoch, the peptide does not have any significant effects in terms of weight loss or lowering of blood sugar level as indicated by the results of prior studies. Most of the studies were conducted with using the in vitro and in vivo techniques, which showed that this peptide can help with maintaining intestinal homeostasis. The peptide is very good in promoting the growth of epithelial cells of the intestine, strengthening the barrier function of the intestine, and dangerous substance prevents from penetrating the intestine и boost inflammatory damage.
GLP-3 is linked to the chronic condition of low-grade inflammation that is thought to be responsible for many chronic metabolic conditions such as fatty liver, insulin resistance, and vascular lesions. In laboratory tests, it has been confirmed that long-term application of GLP-3 leads to reduced amount of pro-inflammatory substances in the body, improvement of general condition of inflammation in the body, as well as normalization of disturbed processes of energy metabolism.
Another important aspect of GLP-3 investigation is its possible connection with the metabolism in the nervous system. The peptide GLP-3, whose production occurs in the brain, can cross the BBB in animals, participate in the process of energy sensing in the human CNS, and influence metabolism activities in the nervous cells. GLP-3 differs from GLP-1 in terms of appetite effects, as this peptide can regulate neuro-inflammatory processes and influence activity of nerve cells.
Jedoch, at present, GLP-3 is investigated mainly in the laboratory conditions. Currently, all information and conclusions regarding its biological functions, mechanisms of action, and regulatory impacts are obtained mainly from cell culture experiments and tests on rodent models. The molecular pathways of GLP-3 activity in humans, effective concentration of the substance, safety profile, and possible side effects have not yet been verified through clinical studies.
Due to the developing nature of research in biomedicine GLP-3 can become the new successful target for attacking the intestinal inflammatory disorders and chronic metabolic diseases.
