Adiponectin
Adipose Tissue, Adipokines and Appetite Regulation
Adiponectin
Adiponectin is an adipose-derived protein hormone circulating in several oligomeric forms. It acts through receptor systems involved in glucose and lipid regulation.
Adipose tissue sends information
Adipose tissue contains adipocytes, vascular cells and immune populations with distinct secretory contributions. Depot, energy status and inflammation influence the resulting endocrine profile. A circulating association does not establish the producing cell or prove a causal metabolic effect.
Specific considerations
Concentration patterns differ from those of leptin and depend on metabolic context. Associations with insulin sensitivity do not independently establish a clinical benefit from manipulating one measured value.
Appetite is integrated
Hunger and food intake reflect endocrine signals together with neural reward, meals, sleep and environment. Low energy availability can occur at different body sizes. No single adipokine concentration can independently determine an athlete's fueling requirements.
