Pregnancy-induced mechanisms regulating central and peripheral leptin sensitivity: lessons from sheep.

This review describes various aspects of the leptin resistance phenomenon and related physiological mechanisms that occur in pregnant sheep. Its main aim is to analyze the mechanisms that determine the occurrence of pregnancy-induced leptin resistance and to investigate the accompanying processes that affect the physiology of pregnancy and lactation in livestock. The main purpose of this analysis was to comprehensively understand the phenomenon of leptin resistance, including the causes of its emergence and its effects on nonrodent organisms.
