Introduction to Pharmacology and Cell Signaling
- Pharmacology is the study of the interaction between a chemical substance and a living system.
- A drug is a chemical substance, natural or synthetic, that can affect a biological or living system.
- Pharmacology has two main subdivisions: pharmacodynamics and pharmacokinetics.
- Pharmacodynamics describes the effect of a drug on the body, its mechanism of action, and its binding to a receptor.
- Pharmacokinetics describes the effect of the body on the drug, including absorption, distribution, metabolism, and elimination.
- Cell signaling is how cells communicate with each other using chemical compounds called ligands.
- Ligands are proteins or other molecules produced by a sending cell and released into the extracellular space.
- Receptors are macromolecule structures made of protein chains that receive and interact with ligands to produce a physiological or pharmacological effect.
- Signal transduction is the series of biochemical and molecular activity changes occurring inside the cell following ligand-receptor binding.
- Receptors are classified into two main categories: cell surface or transmembrane receptors and intracellular receptors.
- Cell surface transmembrane receptors include ligand-gated ion channel receptors, G-protein coupled receptors (GPCRs), and enzyme-coupled receptors.
- Understanding pharmacology and cell signaling is important for developing drugs that can effectively target specific receptors and produce desired physiological or pharmacological effects.
