Peptides regulating food intake and their role in metabolic syndrome
Buderová, Markéta ; Maletínská, Lenka (advisor) ; Hojná, Silvie (referee)
Unhealthy lifestyle together with genetic factors can lead to serious health problems like metabolic syndrome (MetS). MetS is a cluster of risk factors such as abdominal obesity, dyslipidemia, insulin resistance and hypertension. Each component of MetS contributes to cardiovascular diseases, type 2 diabetes mellitus (T2DM) and non-alcoholic fatty liver disease. Treatment of MetS is primarily focused on lifestyle modification, especially weight loss. In severe cases, pharmacological treatment is also used. Pharmacological treatment includes peptide analogues that regulate food intake. Anorexigenic (food- reducing) peptides are involved in the regulation of food intake, together with orexigenic (food- increasing) peptides, which thus play an important role in maintaining energy homeostasis. Several analogues of anorexigenic peptides regulating food intake are already used for the treatment of obesity or T2DM. Other peptide analogues are in preclinical stages of testing or in the development of stable analogues. Elucidating the physiology and pathology of both anorexigenic and orexigenic peptides in the regulation of food intake may contribute to finding potential treatments for metabolic, cardiovascular, and other disorders.
