NEUROTRANSMITTERS NTs (Handout, Learn 1 ) Revised 10/15/15
... The effect of any NT could be depolarization (to create an EPSP) or hyperpolarization (to create an IPSP). It is the receptors present at the cleft that determine the response. Therefore, the same NT may have a stimulating effect in one part of the brain and an inhibitory effect in another. Any give ...

Mechanisms of Hormone Action
... Hormones are chemical messengers that invoke profound changes within target cells. There are two fundamental mechanisms by which such changes occur: • Activation of enzymes and other dynamic molecules: Most enzymes shuttle between conformational states that are catalytically active versus inactive, ...

Purinergic signalling
Purinergic signalling (or signaling: see American and British English differences) is a form of extracellular signalling mediated by purine nucleotides and nucleosides such as adenosine and ATP. It involves the activation of purinergic receptors in the cell and/or in nearby cells, thereby regulating cellular functions.The purinergic signalling complex of a cell is sometimes referred to as the “purinome”.
