Leptin
From MEpedia, a crowd-sourced encyclopedia of ME and CFS science and history
Leptin is a hormone involved in energy expenditure. Blood leptin levels vary exponentially with body fat mass (not linearly). Higher leptin levels are correlated with higher levels of inflammation.
Purpose[edit | edit source]
Leptin is primarily produced in the adipocytes of white adipose (fat) tissue. It helps to regulate energy balance by inhibiting feelings of hunger.
In M.E.[edit | edit source]
Two studies found correlation between leptin levels and symptom severity.[1][2] Another study found raised leptin levels in patients.[3] Several other studies have been published on leptin in ME and CFS.[4][5][6]
Australian researcher Michael Musker is undertaking a study entitled "Chronic fatigue syndrome: Leptin, interleukin 6 and clinical symptoms".[7][8]
