SUMMARY

1. The recognition of chemical messengers by cells depends on interaction with receptors.

2. When a hormone/neurotransmitter is present in excess, the number of active receptors is down-regulated. This occurs through internalization or desensitization.

3. Internalization: receptor-mediated endocytosis decreases the number of available receptors.

4. Desensitization: receptors are modified in ways that make them less responsive.

5. When a messenger is deficient, there is an increase in the number of active receptors.
