Study Notes
Receptor Types
- G-Protein Coupled Receptors (GPCRs) are involved in activating G-proteins and secondary messengers like cAMP, IP3, and DAG.
- Metabotropic receptors specifically activate G-proteins and establish significant cellular responses.
Neurotransmitters
- Norepinephrine is primarily associated with adrenergic receptors, playing a crucial role in the sympathetic nervous system.
Heart Regulation
- M2 Muscarinic Receptors in the heart function to decrease heart rate, contrasting with β1 adrenergic receptors which increase heart rate and contractility.
- Activation of β2 adrenergic receptors in the lungs results in bronchodilation, improving airflow.
Hypertension Treatment
- Aliskiren is a direct renin inhibitor, specifically utilized for treating hypertension.
- Clonidine acts as an α2 agonist, also employed in managing hypertension.
Cholinesterase Inhibitors
- In treating Alzheimer's disease, cholinesterase inhibitors aim to increase acetylcholine levels in the brain, enhancing cognitive function.
Parkinson's Disease
- Pramipexole is a commonly used dopamine agonist in the treatment of Parkinson's disease, improving motor control.
Bladder Management
- β3 receptor activation induces bladder detrusor relaxation, aiding in preventing excessive urination.
Migraine Treatment
- 5HT1B/1D receptors are targeted for migraine treatments; their activation leads to vasoconstriction of cerebral blood vessels.
Gastric Acid Secretion
- Stimulation of H2 receptors is associated with increased gastric acid secretion in the stomach, influencing digestive processes.
