Up regulation is the process when there is an increase of receptors on the surface of cells making them more sensitive to agents such as hormones. This is generally associated with pregnancy because hormone levels vary all the time. Up regulation activity increases signalling the cells to prepare for labor and delivery.

What is receptor desensitisation?
Receptors generate a cellular response upon binding their specific ligand. This response can vary in magnitude. Desensitisation is a phenomenon in which activation of a receptor can reduce the magnitude of the response if it is subsequently activated again. Usually the longer a receptor is activated for the greater the desensitisation will be. There are 3 general mechanisms as to how desensitisation occurs. The first is uncoupling of the receptor from proteins which generate the cellular response. The second is internalising receptors so that they cannot be activated. The third is reducing production of receptors so less are available. In general mechanism 1 is short term, 2 is mid-term and 3 is long term.
Which of the general categories of sensory receptor are located in the body except the brain?
Pain receptors
Which receives signals a fluid mosaic model or a receptor?
a receptor
What are important tissue receptor tumor markers?
Important tissue receptor tumor markers include estrogen receptor (ER), progesterone receptor (PR), and human epidermal growth factor receptor 2 (HER2) in breast cancer; epidermal growth factor receptor (EGFR) and anaplastic lymphoma kinase (ALK) in lung cancer; and the androgen receptor (AR) in prostate cancer. These markers help guide treatment decisions and predict response to targeted therapies.
Is CD4 an adhesion molecule?
The glycoprotein CD4 is a co-receptor. A co-receptor is "a cell surface receptor, which, when bound to its respective ligand, modulates antigen receptor binding or affects cellular activation after antigen-receptor interactions." (MediLexicon)
What is the receptor for equilibrium?
The Macula is the receptor for static equilibrium.
What receptor does aroma therapy stimulate?
What receptor is stimulated by aromatherapy
What is a molecule that acts as signal when it binds to a receptor?
Intracellular receptor
A protein on the cell membrane binds and recognized to specific substance is called a?
It is called a receptor protein.
How long does receptor activation take?
Receptor activation can happen within milliseconds to seconds when a ligand binds to the receptor, triggering a conformational change. The time it takes for the receptor to fully activate and initiate downstream signaling pathways can vary depending on the specific receptor and the cellular context.
What does the phrase density of receptor cells mean?
Density of receptor cells are the amount of receptor cells in a specific area of the body. This could be in the lips.
Drugs that increase receptor activation are those that?
Drugs that increase receptor activation are known as agonists. They bind to the receptor and produce a biological response. This can lead to a variety of effects depending on the specific receptor and drug involved.
