Adipose tissue, specifically adipocytes within the tissue, produce leptin and adiponectin (Reference 9). While adipose tissue contains various cell types, these two hormones are specifically secreted by the adipocytes themselves (Reference 9).
Adipose Tissue and its Hormones
Adipose tissue is more than just a storage site for fat. It functions as an endocrine organ, producing and secreting various hormones and proteins that influence metabolism, inflammation, and other physiological processes. The main cell type responsible for this hormonal activity is the adipocyte.
Key Hormones Secreted by Adipocytes
| Hormone | Primary Source | Function |
|---|---|---|
| Leptin | Adipocytes | Regulates appetite, energy expenditure, and reproductive function. |
| Adiponectin | Adipocytes | Improves insulin sensitivity, reduces inflammation, and protects against cardiovascular disease. |
It is important to remember that adipose tissue is a complex tissue comprising of adipocytes, connective tissue matrix, nerve tissue, stromovascular cells, and immune cells (Reference 8). While adipocytes secrete hormones like leptin and adiponectin, the nonadipocyte components also contribute to the production of secreted proteins (Reference 9).
