Hormones are chemical messengers that interact with receptors present on the surface of a cell membrane or with receptors that are located inside the cell, in the cytoplasm (cytoplasmic receptors).

Hormones are signals or chemical ... hormones to target cells so they can mediate their actions; The signal from the hormone may be conveyed by second messengers within the cells; Finally, once ...

The hormone is made not only in fat tissue but also in immune cells known as macrophages within muscle, where it helps with repair after an injury (Nat. Commun. 2017, DOI: 10.1038/s41467-017-00522-7).

A team from the Institut Curie, Inserm, and CNRS[1] has uncovered a new molecular mechanism, previously unknown, linking ...

The researchers found that when the stress hormone levels were heightened, it prevented these cells from secreting a molecule called Gas6, which was shown to activate the hair follicle stem cells.

Mature fat cells produce a hormone that regulates the differentiation of nearby stem cells in response to glucocorticoid hormones and high-fat diets, researchers have found.
