According to a study from the United States, "Migration and hibernation in mammals may be preceded by a period of leptin resistance, which may in part account for the increasing adiposity and body mass that occurs during these periods. We hypothesized that hypothalamic expression of leptin receptor mRNA would decrease during the premigration (PM) period in the little brown myotis, Myotis lucifugus."

"Body mass of M. lucifugus increased during the PM period, but serum leptin levels did not change during that time. Hypothalamic mRNA levels for both the short (ObRa) and fully active long (ObRb) forms of the leptin receptor increased during PM, but the relative increase in...
