Term for molecule that is released within a cell when a hormone binds to a receptor and transmits signals (hormone cannot enter cell directly).
second messengers
What are 2 important examples of second messengers?
cAMP
tyrosine kinase
What kind of receptor interaction allows for a molecule to enter the cell since it is lipophilic and bind to nuclear receptors within a cell?
steroid receptor interactions
Term for mode of action when hormone is secreted in interstitial fluid and then into the circulation.
endocrine
Term for mode of action when hormone is secreted into a synapse and its effect is either local or at the level of the brain.
neuroendocrine
Term for mode of action where cell secretes a growth factor which binds to its own receptor or on a neighboring cell of the same class.
autocrine
Term for mode of action where hormone is secreted in interstitial fluid and the effect occurs nearby and does not go into the circulation.
paracrine
When a hormone first contacts a receptor, it leads to _________, while after prolonged exposure it leads to ________.
up-regulation
down-regulation
