Receptor (Overview)

An organ, cell or molecule that accepts an outside signal and causes an internal change. Eyes receive light, touch receptors send messages to the brain when stimulated by pressure and estrogen receptors bind Estradiol causing responses of normal breast, ovary and uterus cells to rising and falling levels of the female steroid hormones. Most of the time "receptor" refers to one of the molecular typ.

What is receptor expression?

What is receptor expression?

Surface receptors: Each cell has a membrane surface with numerous different proteins that can interact with other signals- proteins or small molecules like hormones- producing reactions within the cell. The nucleus and other parts of the cell control what receptors are present on the surface and how many. This is the biologic machinery and communication network of all biologic systems. ...Read more

Does the body always build a tolerance to a drug you take, or the receptor it affects?

Does the body always build a tolerance to a drug you take, or the receptor it affects?

Not always: The body does not necessarily build a tolerance to all medications. Some are more prone to this than others, such as pain medications and benzodiazepines (ex xanax). Persons taking these medications long term will usually require more of the medication over time to get the same response. Most other medictaions do not result in building up tolerance. ...Read more
